Oversize Permits and Escort Requirements by State

Legal limits, permit triggers, pilot car rules and official state permit links in one map, built for heavy haul and open deck freight moving out of Los Angeles.

Oversize basics

When Does a Load Need an Oversize Permit?

Five quick checks before you book an open deck or heavy haul truck. Each state then adds its own permit, escort and travel rules.

Planning guide only. General examples for planning, not legal advice, a permit or a route approval. Rules change, and each state’s permit office and your issued permit control. IZ Freight makes no warranty and is not liable for decisions based on this page. Verify with the state DOT before you move. Last checked Oct 16, 2026.

8 ft 6 inLegal width

Wider than 8 ft 6 in?

Federal rules set 102 inches as the standard width on the National Network. Anything wider is a wide load and needs a permit in every state it crosses.

80,000 lbInterstate gross

Heavier than 80,000 lb?

The federal Interstate limit is 80,000 lb gross, 20,000 lb per single axle and 34,000 lb per tandem, plus the bridge formula. Non-divisible loads over that need an overweight permit.

13 ft 6 in to 14 ftTypical legal height

Taller than the state allows?

Legal height is set by each state, often 13 ft 6 in in the East and 14 ft in much of the West. Over that needs a permit, and very tall loads can need a height pole and route survey.

Pilot carsEscort thresholds

When do you need escorts?

Each state sets its own width, height and length triggers for pilot cars, and the permit tells you how many and where they run. Pick any state on the map below to open its official permit office, phone and escort rules.

DaylightTravel windows

When can the load move?

Most states limit oversize moves to daylight, keep wide loads off the road on major holidays, and add city curfews. The permit is the final word.

Permit and escort tiers explained

California oversize permits: key facts

Legal without a permit: 8' 6" (102 in) wide, 14' 0" high, 20,000 lb single axle, 34,000 lb tandem, bridge table up to 80,000 lb^12,16,25,27.
Legal length: 40' 0" single vehicle; 65' 0" California Legal combination; STAA 53' 0" trailer with 40' 0" kingpin to rear axle^18,19,20.
Caltrans permits cover state highways only. Cities and counties issue their own permits for local streets^31,254.
Pilot rules by route color begin over 10' 0" wide, and any Caltrans-permitted load over 12' 0" wide needs pilot cars^53,55,254.
Over 15' 0" wide (16' 0" on yellow routes) means a CHP escort and a variance^59,87.
A single trip permit is valid for seven consecutive days and is issued no more than three working days before the first travel day⁸⁸.
Apply in CTPS and build the route in CalRoute^242,243.
Loads over 10' 0" wide face weekday metro curfews in Los Angeles, San Diego, Sacramento and San Francisco^53,77.

Legal limits and the six things to check before you book.

Caltrans issues permits for state highways under Vehicle Code 35780. Cities and counties issue their own permits for local streets³¹. Caltrans follows the Transportation Permits Manual, which state regulation adopts⁴³. Every state highway is coded twice: for size on the truck and pilot car maps, and for weight through bridge ratings by axle class⁷⁷.

Legal width: 8' 6" (102 in)¹²
Legal height: 14' 0", and over 13' 6" only where clearance is safe¹⁶
Legal length: 40' 0" single vehicle; 65' 0" California Legal combination; STAA 53' 0" trailer with 40' 0" kingpin to rear axle^18,19,20
Legal weight: 20,000 lb single axle, 34,000 lb tandem, bridge table up to 80,000 lb^25,27
Permit office: Caltrans Transportation Permits, 1120 N Street, Sacramento. (916) 322-1297, 8 am to 5 pm Monday to Friday, closed state holidays⁷²

Before you book

Exact numbers. If the dimensions or weights checked in the field do not match the permit, the permit is void⁵³.
Timing. A single trip permit is valid for seven consecutive days and is issued no more than three working days before the first travel day⁸⁸.
Red routes. Annual permits are not valid on red pilot car routes, so those segments need a single trip permit⁵³.
CHP escorts. For a variance that needs a CHP escort, CHP and you must agree a move date within 7 calendar days of preliminary route approval, or the permit waits in a six-month queue⁸⁹. Caltrans re-issues a queued permit once you and CHP notify the Caltrans Variance Permits Office at least 14 calendar days before the move date⁸⁹.
Rush hours. Loads over 10' 0" wide face weekday metro curfews in Los Angeles, San Diego, Sacramento and San Francisco^53,77.

Written for shippers, freight forwarders, construction companies, equipment dealers, brokers and buyers alike. It covers California oversize permits, overweight and heavy-haul routing, Port of Los Angeles and Long Beach moves, construction equipment transport and high-value freight staging.

How IZ handles it

IZ Freight plans the move from Los Angeles and books it through our network of carriers, powered by Armstrong Transport. The carrier on the load files the Caltrans and local permits, books pilot cars or CHP escorts when the permit calls for them, and runs the permitted route. Our job is to get your dimensions, weights, dates and pickup details right up front, so the permit matches the load at the scale.

Width: too wide

Legal width, when pilot cars and CHP come in, signs, curfews and watch-outs.

Route color

What the colors mean

Single trip rules from the Caltrans pilot car maps. A limit applies when the load is over the number, except the blue and brown CHP height trigger, which starts at 17' 0". Red routes have their own rules. Planning only; the permit controls.

Sources for the slider: pilot car legend, CHP escort table, variance timing, height and survey rules, signs and holiday conditions^{2,16,17,23,53,55,59,87,89}.

Legal without a permit

Legal width: 8' 6" (102 in)¹²

Special mobile and construction equipment can run up to 120 in wide under the listed exemptions¹³.
Manufactured homes can get width permits up to 14' 0"³⁷.
Cities may ban combinations wider than 96 in on posted streets¹².

Bay Bridge tunnel. Loads over 14' 0" high need a CHP escort westbound through the Yerba Buena Island tunnel⁷⁷.

Route limits: red, dashed and coast

Wire heights are minimums. CPUC General Order 95 sets minimum wire heights when lines are installed²⁵⁷.
Over urban streets and rural road crossings: 18' 0" for communication lines and 20' 0" to 30' 0" for supply lines, by voltage²⁵⁷.
Sag and heat change real heights, so loads near these heights need a measured route survey²⁵⁷.
Keep clear of energized lines. Keep every part of the load at least 6' 0" from lines of 600 volts to 50 kV, 10' 0" up to 345 kV, 16' 0" up to 750 kV and 20' 0" up to 1,000 kV²³⁷.
Treat every line as energized until its owner confirms it is not and it is visibly grounded at the site²³⁷.
Cranes traveling. A spotter is required if any part of boom equipment will come within 20' 0" of a line²³⁸.
Encroachment permit. Work in the state right-of-way needs a separate Caltrans encroachment permit⁷⁹.

Route survey for loads over 17' 0" high: every structure, wire and owner, tight turns, fuel stops, overnight parking, speed and timing. The transporter certifies in writing that signal, wire and sign removal is arranged⁷⁶.

Length: too long

Overall length, overhang, kingpin to rear axle and the LONG LOAD sign.

Legal without a permit

Legal length: 40' 0" single vehicle; 65' 0" California Legal combination; STAA 53' 0" trailer with 40' 0" kingpin to rear axle^18,19,20

Front overhang is legal to 3' 0" past the front tires or bumper, or 4' 0" for vehicle loads²².
On a permit, front overhang over 25' 0" needs a pilot. The maximum is 30' 0"⁷³.
Rear overhang is legal up to two-thirds of the wheelbase, past the last point of support²³.
On a permit, rear overhang over 25' 0" needs a pilot. The maximum is 35' 0"^73,77.
Ask the permit writer where the 25' 0" is measured from; the manual gives two methods^73,77.

Will my trailer make it? North Coast and Tahoe

One card per area. Each gives the roads in and a short answer for a 53' trailer and for a 48' trailer or shorter.

What a kingpin advisory means. A yellow advisory (30 to 38 ft) is a warning, not a ban⁶⁵. On a permit, KPRA over 38' 0" needs a pilot^54,77. A 53' trailer can have KPRA up to 40' 0"²⁰, so on a 30' advisory road, measure yours first, and if it is over 30' 0", pick a trailer that measures 30' 0" or less. Where it is a ban: SR 108 at Sonora Pass prohibits KPRA over 38' 0"⁵⁸, and on a permit, the SR 1 red segments in Marin and Sonoma apply, including a CHP escort for any 2-vehicle combination between Northern Ave and Stinson Beach⁵⁷.

Eureka and Arcata

From the south on US 101 (Richardson Grove) or from Redding on SR 299

SR 299 from Redding to US 101 is an STAA route²²². Coming up US 101 from the south, Richardson Grove carries a 32' kingpin advisory for 2.9 miles, and from the Humboldt County line south to about Leggett the road is California Legal, which means 65' 0" overall⁵⁷¹⁹.

53' trailer: Mixed: pick your roadSR 299 from Redding is the easy way in. On US 101 through Richardson Grove, the 32' advisory applies, and the combination must fit 65' 0" overall on the California Legal stretch.
48' trailer or shorter: Mixed: pick your roadSame choice: SR 299 is open, and on US 101 the 32' advisory and the 65' 0" overall rule on the California Legal stretch still apply.

Crescent City and the Oregon line

US 101 north from Eureka, or US 199 from Oregon

US 101 from Eureka to Crescent City and the Oregon line is an STAA Terminal Access route⁵⁷. US 199 carries a 30' kingpin advisory⁵⁷. On a permit, US 199 has red segments from US 101 to SR 197 and from the Middle Fork Smith River to the Oregon line⁵⁷.

53' trailer: Open routeUse US 101 from Eureka. On US 199, the 30' advisory applies to your KPRA.
48' trailer or shorter: Open routeUS 101 is open. On US 199, the 30' advisory applies to your actual KPRA.

Fort Bragg, Mendocino and the Sonoma and Marin coast

SR 1, SR 20, SR 128 and SR 253

Every way in, SR 1, SR 20 from Willits, SR 128 and SR 253, carries a 30' kingpin advisory, with short California Legal pieces near Fort Bragg and Willits⁵⁷²²¹. On a permit, SR 1 in Sonoma and Marin has red segments, and between Northern Ave and Stinson Beach CHP escorts any 2-vehicle combination⁵⁷.

53' trailer: Advisory: check KPRACheck your KPRA before you book; a 53' trailer can measure up to 40' 0", well over the 30' advisory.
48' trailer or shorter: Advisory: check KPRAThe 30' advisories still apply to your actual KPRA, so measure it first.

Humboldt inland

SR 36 and SR 96

SR 36 carries a 30' kingpin advisory from US 101 near Alton to near Dinsmore⁵⁷. SR 96 carries a 36' advisory in Humboldt and 30' at Happy Camp, and eastbound STAA trucks may not turn right onto southbound SR 263⁵⁷. On a permit, both roads have red segments⁵⁷.

53' trailer: Advisory: check KPRACheck your KPRA against the 30' and 36' advisories before you pick these roads.
48' trailer or shorter: Advisory: check KPRAThe same advisories apply to your actual KPRA.

Lake Tahoe

SR 89, SR 28, SR 267 and US 50

SR 89 from Truckee to Tahoe City and SR 28 along the north shore are STAA routes²²³. SR 267 and US 50 from Pollock Pines to Meyers are California Legal only, which means 65' 0" overall²²³¹⁹. The SR 89 west shore from Homewood to South Lake Tahoe carries a 30' advisory, and on a permit, Meeks Bay to US 50 is a red segment⁵⁷.

53' trailer: Mixed: pick your roadThe north shore via SR 89 and SR 28 is open. On SR 267 and US 50 over Echo Summit, the combination must fit 65' 0" overall; on the west shore, check your KPRA.
48' trailer or shorter: Mixed: pick your roadA 48' trailer combination is also an STAA vehicle, so the same roads apply²⁰.

The 40/38 rule. A 53' 0" STAA trailer may have KPRA up to 40' 0" with two or more axles, or 38' 0" with a single axle²⁰.
A 48' 0" trailer has no KPRA limit²⁰.
California Legal combinations have the same 40/38 limits within 65' 0" overall^18,65.
Advisories. Yellow signs read "over __ feet kingpin to rear axle not advised," from 30 to 38 feet. They are not bans⁶⁵.
On a permit, an advisory route is a dashed route, and KPRA over 38' 0" needs a pilot^54,77.
Enforceable bans. SR 108 at Sonora Pass bans KPRA over 38' 0"⁵⁸.
SR 152 restricts combinations over 45' 0" on the posted segment⁵⁸.
SR 175 restricts vehicles over 39' 0"⁵⁸.
North Coast. US 101 at Richardson Grove carries a 32' advisory with a California Legal segment; US 199 and most coastal state routes (SR 1, 20, 36, 96, 128, 162, 169, 253, 254) carry 30' advisories. SR 299 is STAA from US 101 to Redding^221,222.
Tahoe and Sierra. SR 89 on the west shore carries a 30' advisory. SR 89 from Tahoe City to Truckee and SR 28 are STAA; SR 267 and US 50 from Pollock Pines to Meyers are California Legal only²²³.

Needs a permit when over

Purple: 1.5 x 700 x (L + 40). Tandem maximum 60,000 lb with 8-tire axles, 56,000 lb with 4-tire axles^83,75.
Green: 1.3 x 700 x (L + 40). Tandem maximum 52,000 lb with 8-tire axles, 48,000 lb with 4-tire axles^81,75.
Orange: 700 x (L + 40), minimum 32,000 lb. Tandem maximum 42,800 lb on the Orange chart. Chapter 3 of the Caltrans Transportation Permits Manual lists 42,000 lb with 8-tire axles and 40,000 lb with 4-tire axles^82,75.
L is the spread from first to last axle in the group, in feet^81,82,83.
Axles with 8 tires add 15% on 8' wide axles and 25% on 10' wide axles⁸³.
Axles closer than 3' 6" count as one axle on the charts⁸³.
A single axle on 4 tires charts at 28,000 lb Purple, 24,000 lb Green and 20,000 lb Orange. Steer axles stay limited by their tires^25,83.
A tridem is three axles spread 8' 0" to 10' 4"⁷⁹. Fixed axles on one frame spread more than 10' 4" get no extralegal weight unless they steer⁷⁵.
Groups closer than 18' 1" are close coupled; Caltrans figures them with averaged bonus factors^75,84.
Air or hydraulic booster axles and single-axle "Joe Dog" jeeps are not permitted in California⁷⁹.
Each loading group counts as two axles for routing, so a tractor with a tridem trailer still routes as a 5-axle class⁷⁷.
Bridge analysis covers 5 to 13 axles, up to 135' long⁷⁷.

No extra weight is allowed for a load that can be reduced or repositioned to legal⁵³.
Qualify the equipment. Axles must be at least 96 in wide for extra weight⁷².
A lift axle counts toward extra weight only if its axle group shares one suspension, each axle carries within 10% of an equal share, and the lift controls are outside the cab⁷⁵.
Mixed suspensions in one axle group are not allowed⁷⁵.
Structure review for loads over the Purple chart or a bridge rating. It can take up to two weeks and is valid for 60 days⁷⁶.

Heavy-haul setups and best-case weight

Heavy haul rides on a lowboy (RGN) or a tri-axle trailer. Pick a setup to see what each axle group can carry when every bridge is Purple.

5 axles. Tractor + 2-axle lowboy (RGN). All-Purple best case: 113,450 lb, routed as a 5-axle class.

Tractor + 2-axle lowboy (RGN): Purple chart limit per axle group
Group	Axles	Spread	Purple limit
Steer	1	single	20,000 lb^25,51
Drives	2	4' 6"	46,725 lb^51,83
Trailer axles	2	4' 6"	46,725 lb^51,83
Gross	5		113,450 lb

The basic heavy-haul setup. Routed as a 5-axle class⁷⁷.
The two groups must be at least 18' 1" apart, or the close-coupling math applies⁷⁵.

6 axles. Tractor + tri-axle step deck. All-Purple best case: 126,725 lb, routed as a 5-axle class.

Tractor + tri-axle step deck: Purple chart limit per axle group
Group	Axles	Spread	Purple limit
Steer	1	single	20,000 lb^25,51
Drives	2	4' 6"	46,725 lb^51,83
Trailer tridem (bonus)	3	10' 0"	60,000 lb⁷⁵
Gross	6		126,725 lb

Axles on 60" centers make a 10' 0" tridem. A qualifying bonus tridem gets 60,000 lb; without the bonus it is 52,500 lb, or 119,225 lb gross^51,75.
One bonus tridem with a 3-axle tractor still routes as a 5-axle class⁷⁵.

6 axles. Tractor + 3-axle lowboy (RGN). All-Purple best case: 125,893 lb, routed as a 5-axle class.

Tractor + 3-axle lowboy (RGN): Purple chart limit per axle group
Group	Axles	Spread	Purple limit
Steer	1	single	20,000 lb^25,51
Drives	2	4' 6"	46,725 lb^51,83
Trailer tridem (bonus)	3	9' 0"	59,168 lb⁷⁵
Gross	6		125,893 lb

Axles on 54" centers make a 9' 0" tridem. Without the bonus it charts at 51,450 lb, or 118,175 lb gross^51,83.
Bonus tridems need 4 tires per axle, 8' 0" wide axles and a spread of 8' 0" to 10' 4"⁷⁵.
A bonus tridem cannot be close coupled or mounted on a crane. If the rig has a mechanical booster (MDU), it must be inspected loaded⁷⁵.

7 axles. Tractor + 2-axle jeep + 2-axle RGN. All-Purple best case: 160,175 lb, routed as a 7-axle class.

Tractor + 2-axle jeep + 2-axle RGN: Purple chart limit per axle group
Group	Axles	Spread	Purple limit
Steer	1	single	20,000 lb^25,51
Drives	2	4' 6"	46,725 lb^51,83
Jeep	2	4' 6"	46,725 lb^51,83
Trailer axles	2	4' 6"	46,725 lb^51,83
Gross	7		160,175 lb

A jeep is a short multi-axle dolly that adds a loading group ahead of the trailer⁷⁹. Each group counts as two axles for routing, so this routes as a 7-axle class⁷⁷.
Every group must sit at least 18' 1" from the next⁷⁵.

9 axles. Tractor + 3-axle jeep + 3-axle RGN. All-Purple best case: 185,061 lb, routed as a 9-axle class.

Tractor + 3-axle jeep + 3-axle RGN: Purple chart limit per axle group
Group	Axles	Spread	Purple limit
Steer	1	single	20,000 lb^25,51
Drives	2	4' 6"	46,725 lb^51,83
Jeep tridem (bonus)	3	9' 0"	59,168 lb⁷⁵
Trailer tridem (bonus)	3	9' 0"	59,168 lb⁷⁵
Gross	9		185,061 lb

Two bonus tridems in a 3-vehicle combination route as a 9-axle class⁷⁵. The two tridems must be at least 25' 0" apart⁷⁵.
Without the bonus the tridems chart at 51,450 lb each, or 169,625 lb gross⁸³.
If the gap between the axle groups on either side of the deck is over 40' 0" and the rig is under 135', Caltrans routes it as an 11-axle class⁷⁷.

11 axles. Tractor + 3-axle jeep + 3-axle RGN + 2-axle mechanical booster. Best case: route and bridge review.

Gross	11		Route and bridge review⁷⁷

Caltrans counts a mechanical booster (MDU) and its trailer as one vehicle for routing, so this rig routes as a 3-vehicle combination. Confirm the routing class with Caltrans⁷⁵.
A booster usually sits less than 18' 1" behind the trailer axles. That is close coupling, so Caltrans works out the weight from the actual spacings^75,84.
Only a mechanical distribution unit (MDU) qualifies. Air or hydraulic boosters are not permitted in California^72,79.

13 axles. Tri-drive tractor + 3-axle jeep + 3-axle RGN + 3-axle mechanical booster. Best case: route and bridge review.

Gross	13		Route and bridge review⁷⁷

At most two tridems per combination can take the bonus, and they must be at least 25' 0" apart, so the third tridem charts without it⁷⁵.
A four-axle power unit needs a vehicle inspection for extra weight⁵¹.
Over 135' without a pusher needs a variance⁷⁷.

How these are figured: steer 20,000 lb, tandems on 4' 6" centers, tridems on 54" or 60" centers, and every group at least 18' 1" from the next^25,75,83. Drawings share one scale. Caltrans sets the actual weights on the permit, and trailer, tire and bridge ratings can cut them.

No fixed gross cap. Caltrans permits weight per axle group, not for gross weight, so 150,000 lb is not a Caltrans limit⁷⁵.

Route limits: red, dashed and coast

Bridges are rated by chart. Tandem maximum: 60,000 lb Purple, 52,000 lb Green and 42,800 lb Orange; longer axle groups chart higher. X means no permits⁷⁷.
Each bridge has a five-letter code, one letter for each routed class of 5, 7, 9, 11 and 13 axles (for example PPPGG)⁷⁷.
On the annual maps, a red symbol marks a state bridge closed to Green or Purple loads⁵⁴.

Most moves cross several colors. Pilot and travel rules follow each segment's color. For weight, one Green or Orange bridge sets the chart for the whole move, using the letter for your class⁷⁷. Plan for the hardest segment, not the average.

How to read the colors

YellowGreenBlueBrownRedDashedWhat each color allows

Permit loads are routed on the pilot car maps. Yellow: multilane highways. Green: non-standard freeways and two-lane roads with 12' lanes and shoulders. Blue: two-lane roads with lanes of 11' or more. Brown: narrower two-lane roads. Red: roads with operational restrictions^55,77.
A solid line follows the color rules. A dashed line of any color marks a kingpin advisory; KPRA over 38' 0" needs a pilot^55,77.
Red segments follow their own row in the Red Route Summary Table^54,57.

Search a highway such as I-5, US 101 or SR 1, then tap a road to see whether STAA 53' trucks are allowed, the kingpin limit, the pilot car route color and any red route rules.
Turn on the single trip or annual pilot car maps; annual maps can be switched between California Legal and STAA trucks and Legal, Green or Purple weight.
The map was digitized from 96 Caltrans truck route and pilot car maps, listed under Caltrans route maps in the Sources index. Pilot car colors follow the Caltrans legends^54,55. Basemap data © OpenStreetMap contributors.

Truck routes for legal-size trucks

STAA routes (green National Network and blue terminal access) take STAA trucks: a 48' 0" trailer, or a 53' 0" trailer with KPRA of 40' 0", or 38' 0" on a single-axle trailer²⁰.
California Legal routes (black) allow 65' 0" overall^19,65.
Yellow advisory routes post KPRA advisories from 30 to 38 feet⁶⁵.
Red marks enforceable special restrictions, listed below⁵⁸.

Routes, coast and mountains

SR 1 and the North Coast, Big Sur, Tahoe and the Sierra passes, red routes and the ports.

Check Caltrans QuickMap (quickmap.dot.ca.gov) or 1-800-427-7623 the day you travel. Road conditions can change quickly²⁵².

SR 1, the North Coast and Big Sur

Eureka and Arcata. SR 299 is STAA from US 101 to Redding^50,57.
US 101 from the south is California Legal (65' 0", KPRA 40' 0") through Richardson Grove^50,57.
On the pilot car maps, US 101 runs brown from Crescent City to Big Lagoon and dashed brown through Richardson Grove⁵⁷.
Coast routes. SR 1, 20, 128, 253 and 162 carry 30' KPRA advisories with dashed or red pilot car segments; SR 1 in Marin and Sonoma has red segments, including one that needs CHP for any two-vehicle combination^221,224,57.
North Coast. US 101 and SR 299 have weigh stations at Little River, Ridgewood, Buckhorn and Whiskeytown²⁴⁷.
Big Sur (SR 1). Caltrans reported Highway 1 open, with all emergency projects done, as of January 14, 2026^248,249. Storms can still close it²⁴⁹.

Tahoe and the Sierra passes

Sierra passes. Caltrans closes Ebbetts (SR 4), Sonora (SR 108) and Monitor (SR 89) every winter. Snow removal usually starts the first Monday of April, aiming to reopen before Memorial Day²⁵¹.
After a storm closure, Caltrans reopened Ebbetts from Lake Alpine to Raymond Meadows on October 13, 2026²⁵².
Tahoe. Chain controls stop permit loads⁷².
Holidays, Friday afternoons, Sundays and roads to recreation areas may add limits⁷³.
Some cities and counties require their own night-move permit⁷³.
Loads from Nevada pass a CDFA station at Truckee, Meyers, Long Valley or Topaz²⁵⁶.
Tahoe. SR 89 from Truckee to Tahoe City and SR 28 are STAA. SR 267 and US 50 from Pollock Pines to Meyers are California Legal only, and US 50 runs red on the pilot car map from Ice House Road to SR 89^223,57.

Chains, snow and wind

Chains stop permit loads. No permit travel when chains are mandatory⁵³.
When controls are posted, every heavy vehicle over 6,500 lb must chain up. There is no snow-tire exemption, and cable chains may not be allowed for big rigs⁴⁸.
Where chains hit most. I-5 north of Redding, I-80 over Donner Pass and US 50 at Echo Summit; sometimes SR 58 Tehachapi, I-15 Cajon Pass and I-5 Tejon Pass (the Grapevine)⁴⁸. Check Caltrans QuickMap before dispatch.
Wind. Manufactured housing may not move when wind makes the towed unit whip or swerve, and a wind-related crash is prima facie evidence of a violation⁵³.

Ports of Los Angeles, Long Beach and other California ports

Port of Los Angeles

Overweight container corridor permits allow up to 95,000 lb gross (truck, chassis, container and contents)¹⁰¹.
The Caltrans sea container permit covers 7 axles, KPRA 40' 0", 65' 0" overall and 95,000 lb, with axles of 20,000, 43,500 and 43,500 lb^62,86. Allow at least 14 business days for the annual permit⁶⁴.
City of Los Angeles street permits are separate¹¹⁹.
Caltrans limits travel to three state highway segments: 2.82 miles of SR 47 and SR 103 (Terminal Island Freeway, W 20th Street to Terminal Island), 2.4 miles of SR 1 (Sanford Avenue in Los Angeles to Harbor Avenue in Long Beach) and 1.8 miles of SR 710 (Pier S Avenue on the Seaside Freeway to Pico Avenue)⁸⁶.
VC 35700.5 still lists 3.66 miles of SR 47 and SR 103 plus the SR 1 segment, so follow the permit³⁰.

Port of Long Beach

The City of Long Beach Overweight Vehicle Special Permit covers ocean containers over 80,000 lb, up to 95,000 lb, with a CHP 407F inspection¹²³. The same Caltrans sea container permit applies on the state corridor⁶².

Port of Oakland

Heavy Container Permit Program: separate City and Port permits, with specially inspected 3-axle chassis for 40' containers up to 95,000 lb⁹⁷. Non-compliant trucks hauling overweight or oversize cargo may be admitted at the terminal operator's discretion⁹⁶. The port lists a heavyweight corridor on its trucker page⁹⁸.

Port of San Diego

Tenth Avenue Marine Terminal handles breakbulk with a 100 metric ton mobile harbor crane, 8 acres of laydown and 10 acres covered¹⁰⁴. National City Marine Terminal handles vehicles and project cargo¹⁰⁵.

Port of Hueneme

Breakbulk and project cargo terminal next to Naval Base Ventura County, which runs its own gates^92,114.

Port of Stockton

Tariff truck hours are 8:00 AM to 5:00 PM¹⁰⁷. Berth 2 and Berths 10 and 11 handle heavy lifts, with a marshaling area at 10 and 11¹⁰⁶.

Port of West Sacramento

30' channel. The North Terminal at 2895 Industrial Blvd has had a private operator since July 1, 2013, mainly for bulk cargo such as rice and cement¹⁰⁸.

Port of Richmond

Five city-owned and ten private terminals with BNSF and UP rail. Terminal 3 has two 37 short ton container cranes¹⁰³.

Humboldt Bay

Terminals include Fairhaven, Redwood Marine Terminal Berths 1 and 2, Schneider Dock and Sierra Pacific^94,95. The offshore wind heavy-lift terminal is a proposed project⁹³. Road access from the south is US 101, California Legal (65' 0", KPRA 40' 0")⁵⁰.

Drayage registration and clean truck rules

At Los Angeles, drayage trucks must be in the Port Drayage Truck Registry (PDTR) and the State registry before entry¹⁰⁰.
Since October 1, 2018, only 2014 or newer trucks can be newly entered¹⁰⁰.
The Clean Truck Fund Rate is collected through PortCheck¹⁰².
CARB repealed the Advanced Clean Fleets drayage and high-priority fleet rules (Board Resolution 25-9)¹³². The repeal was approved and filed on September 10, 2026¹²⁹.
Drayage trucks still need state registration and Truck and Bus and Clean Truck Check compliance^130,131,133.

Getting the permit

CTPS steps, timing, superloads, pilot cars and CHP escorts, local permits and insurance.

Caltrans permits cover state highways only, and the routing marks with an asterisk where a city or county permit may be needed²⁵⁴. Any oversize load that crosses a state highway needs a state permit⁷². Caltrans permits only loads that cannot reasonably be divided without ruining their use or value⁷².

Permit types and lead times

Single trip. Valid for seven consecutive days⁸⁸.
Issued no more than three working days before the first travel day⁸⁸.
Return trips can be added, up to 14 days in total⁴⁵.
Repetitive and annual. For repeat moves, under the same statute³¹.
Annual permits are not valid on solid or dashed red pilot car routes; those segments need a single trip permit⁵³.
Annual permits allow one pilot car at most and must follow the weekly short-term restrictions^53,54.
Variance. Needed over 17' 0" high, over 16' 0" wide on yellow routes or 15' 0" on other routes, over 135' 0" long, or for a structure review^76,241.
When a CHP escort is needed, CHP and the permittee must agree a move date within 7 calendar days of preliminary route approval. If not, the permit goes into a six-month "pending CHP release" queue⁸⁹.
Queued permits are re-issued at least 14 calendar days before the move date⁸⁹.
CHP is also required whenever the load uses opposing lanes or must slow to cross a structure⁸⁷.
Emergency moves. Allowed under VC 35002(c), with the written permit obtained afterward⁷⁸.

Rules every permit carries

The permit, paper or electronic, rides in the truck and is shown on demand³³.
Breaking any permit condition is unlawful³⁵.
Inside a city, the driver may leave the route on nonresidential streets only to avoid breaking local traffic rules, then must return to it³⁵.

Single trip and annual permits

Register in CTPS. All applications go through the California Transportation Permit System (formerly STARS2)^72,242.
The route is built in CalRoute, which checks height and weight conflicts before you submit^72,242.
Send exact data. Company details, load description and dimensions, hauling vehicle, kingpin to rear axle, overall length, loaded height, width, front and rear overhang, axle spacings, axle widths and tires⁷².
Inspection report when needed. Required for four-axle power units, steer axles over 20,000 lb, cranes and other fixed loads, combinations of 9 or more axles and mechanical distribution units. Allow about two weeks⁷⁵.
Out-of-state companies need them too⁵¹.
Pay on time. After approval, an unpaid single trip application is denied after 6 business hours, or 16 for annual²⁴².
Incomplete applications are denied. Applications are handled in the order received⁷².
Carry the permit. Single trip and variance permits may be printed or electronic. Annual and repetitive permits must be the original hard copy⁷².
No signal or a dead phone still counts as no permit²⁵⁴.
Changes need a rider. Any change needs a permit rider or a new permit, and permits cannot be transferred⁷².
Recheck bid routes. Caltrans will check a route for a future move, but the answer is not binding and must be rechecked before the move⁷².

Variance (superload) steps

Justify the move. Show the load is still over the limits at its smallest size and weight, and that no other mode is reasonably available. Cost alone is not a reason⁷⁶.
Equipment review first if the hauling equipment is non-standard⁷⁶.
Apply at least 30 days before the move. There are no verbal approvals, and incomplete applications are denied⁷⁶.
Route survey for loads over 17' 0" high, certified in writing by the transporter⁷⁶.
Structure review for loads over the Purple chart or a bridge rating. It can take up to two weeks and is valid for 60 days⁷⁶.
District review, then issue. The District Traffic Manager reviews the route and can recommend another route or time⁷⁶.
CHP escort if required. Do not book CHP until Caltrans has approved the route⁷⁶.

Common reasons for denial

Less than 3 in of clearance under any structure⁷².
A combination over 135' 0" (that goes to a variance)⁷².
More than 7 loading groups⁷².
Front overhang over 30' 0"⁷².

Pilot cars and CHP escorts

Placement. One pilot leads on 2- or 3-lane highways and follows on highways of 4 or more lanes, divided highways and freeways^77,254.
With two pilots, one leads and one follows. A pilot for rear overhang always follows^77,254.
Duties. Pilots keep radio contact with the load and cross every open CHP scale with it⁷⁷.
Pilots may not stop or hold opposing traffic, tow, or escort more than one load unless the permit allows it⁷⁷.
Out of service. Not meeting the pilot car rules puts the load out of service until fixed⁷⁷.

CHP escorts

Show full table: CHP escort guideline

CHP escort guideline (CHP manual HPM 82.6, 2021). Where it differs, the Caltrans CHP escort table in TPPM 2021-01 and the escort trigger table above govern.
Route (pilot car color)	CHP escort likely when	Source
A: Yellow (multilane, 12' lanes)	Width 17' 0" or more with 3+ lanes; 16' 0" or more with 2 lanes	²⁵⁴
B: Green	Width over 15' 0"	²⁵⁴
C, D, E: Blue, Brown, Red	Width over 15' 0", or length over 135' 0"	²⁵⁴
Any route	Over 17' 0" high needs route review; any obstacle within 3 inches of load height may require CHP	²⁵⁴

Process. Caltrans notifies the CHP Division variance coordinator, who reviews the route survey and permits. The carrier signs a CHP letter of agreement²⁵⁴.
Lead time. CHP recommends about 10 business days for typical escorts and about four months for larger escort contracts. Book only after Caltrans approves the route^76,254.
Day of move. A current CVSA Level I decal is required, or CHP does a Level I inspection²⁵⁴.
The carrier supplies radios. Missing or mismatched permits from any agency delay or cancel the escort²⁵⁴.

Local street permits

Cities and counties issue permits for their own streets, so a load going to a jobsite or yard usually needs both³¹.

Show full table: local agency permits

Local agency permits on top of Caltrans
Agency	Key rules	Source
Los Angeles County Public Works (unincorporated + contract cities)	TPAP online; apply 2 business days ahead near holidays; structures review 10 business days or more; night moves 3 weeks ahead; office hours differ between the web page (7 to 5 Mon to Fri) and the contacts PDF (Mon to Thu); call ahead	^120,121,122

Insurance and liability

No bond and no proof of insurance are normally required for a Caltrans permit⁷².
The transporter must meet the financial responsibility law and is liable for damage to the highway, people or property⁷².
Exception. Caltrans or a local agency may require extra insurance or other security for unusually large or heavy loads that put public facilities at substantial risk³².
Route responsibility. An employee or contractor who leaves a written route can be personally guilty of a misdemeanor³⁵.

Who to call

Single trip, annual, repetitive: (916) 322-1297⁵²
Variance permits: (916) 323-2893⁵²
Construction restrictions in CalRoute: Liaison.Permits@dot.ca.gov²⁴⁴
After-hours emergencies: Caltrans HQ Communication Center, (916) 653-3442. Applying late is not an emergency⁷²

Checklist and common traps

Checklist

Give exact dimensions and weights, to the inch and pound. If field checks differ, the permit is void⁵³.
Ask early: a single trip permit is issued no more than 3 working days ahead and is valid 7 days⁸⁸.
Variances with CHP are re-issued 14 calendar days or more before the move⁸⁹.
Los Angeles County structure review takes 10 business days¹²⁰. Los Angeles City loads over 18' high need 4 days¹¹⁹.
Do not plan pilot-car moves for holiday afternoons⁶⁰; Thanksgiving starts Wed 4 PM⁷⁷.

Traps

CHP recommends about 10 business days' notice for an escort, and about four months for larger escort contracts. Separately, on a CHP escorted variance, you and CHP must agree a move date within 7 calendar days of preliminary route approval, or the permit waits in a six-month queue^89,254.
Report damage to state property within 72 hours⁵³.
Stop at all scales⁵³.
No convoys unless the permit says so⁵³.

What officers check

The permit. Immediately available, unaltered, with every attachment and rider²⁵⁴.
Dimensions. Any amount over the permitted width, length or height is a violation. Length is measured on both sides and averaged²⁵⁴.
Weight. Checked per axle and axle group; gross is not considered on an extra-weight permit²⁵⁴.
Axle spacing. "MIN" means more is fine, "MAX" means less is fine, and an unlabeled spacing must be exact²⁵⁴.
Route and conditions. Off route is a statutory violation. Time of day, weather, pilot cars, signs and flags are all checked²⁵⁴.
Divisibility. If moving or removing part of the load would make it legal, the permit is invalid²⁵⁴.

An officer can order the load adjusted or removed at a safe spot, or stop the move until a permit is obtained²³⁵.
Every commercial vehicle must stop at an open scale when signs say so, cranes and fixed-load rigs included^246,254.
Pilot cars cross the scale with the load⁷⁷.

Caltrans compliance points

Points add up over a rolling 12 months and can suspend permit privileges²³⁹.
Major violations, 6 points: no permit, off route, an altered permit, a curfew or night violation, missing pilots, or a load not as described²³⁹.
Minor violations, 3 points: a reducible load, or missing signs or flags²³⁹.
Width or length over the permit: 1 point per foot. Weight up to 6,000 lb over: 1 point per 1,000 lb²³⁹.
Privileges are suspended immediately for a bridge hit, or, when not authorized on the permit, height over 17' 0", width over 16' 0" on yellow routes or 15' 0" on other routes, length over 135' 0", or weight more than 10,000 lb over the permitted weight²³⁹.

Frequently asked questions

Do I need a California permit for a load that just crosses a State highway?

Yes. Any crossing of a State highway needs a State permit, and a city or county permit is likely at the ends⁷².

Does a Caltrans permit cover city streets?

No. It covers only State highways. An asterisk in the routing marks where a local permit may be needed²⁵⁴.

How far ahead can I get a single trip permit?

Up to 3 working days ahead⁸⁸. A variance needs at least 30 days⁷⁶.

Can I email my application?

No. Apply in CTPS and build the route in CalRoute^242,243.

What happens if I don't pay right away?

Single trip applications are denied after 6 business hours unpaid; annual applications after 16²⁴².

Can the driver show the permit on a phone?

Yes for single trip and variance permits. Annual and repetitive permits must be the original hard copy. No signal means non-compliant^72,254.

How do I change a permit after it's issued?

Get a rider or a new permit⁷².

Can I move a sea container on an oversize permit?

Generally no. Containers are treated as reducible, so single trip permits are allowed only when justified to protect critical surfaces. Annual container permits are available, and there is a separate overweight container permit for the port corridor^74,254.

When does my load become a superload (variance)?

Over 17' 0" high, over 16' 0" wide on yellow routes or over 15' 0" on others, over 135' 0" long, or when a structure review is needed⁷⁶.

How wide can I go before I need pilot cars?

Pilots are required over 12' 0" wide. They may also be required on narrower loads depending on the route²⁵⁴.

One pilot car: front or back?

Front on 2–3 lane roads; back on 4+ lane roads, divided highways and freeways. When the pilot is required for rear overhang over 25' 0", it follows on every road⁷⁷.

What equipment does a California pilot car need?

At least 60 in wide; company name on both sides; amber warning lamps; a yellow OVERSIZE sign of at least 440 sq in mounted with its bottom 48 in or more above the road; red flags; a STOP/SLOW paddle; a vest; a hand flag; a two-way radio^8,254.

When will CHP escort my load?

When it meets the CHP escort table: over 16' 0" wide on yellow routes (CHP's own table uses 17' 0" where there are 3 or more lanes) and over 15' 0" on green, blue and brown routes; over 185' 0" long on yellow and green routes or over 135' 0" on blue and brown routes (green, blue and brown routes have no length trigger on controlled-access roadways); 17' 0" or more high on blue and brown routes; or when the load must slow to cross structures. Red routes have their own restrictions, and any load over 17' 0" high also needs a route survey^87,254.

How much notice does CHP need?

About 10 business days for typical escorts and about four months for larger escort contracts. Book only after Caltrans has approved the route^76,254.

What does CHP inspect before an escorted move?

A current CVSA Level I decal (or a Level I inspection), all permits from every jurisdiction, and radios for all escort vehicles²⁵⁴.

Do I need my truck inspected by Caltrans?

Yes for 4-axle tractors, steer axles over 20,000 lb, cranes and fixed loads, 9+ axle combinations and MDUs, including for out-of-state carriers. Allow about 2 weeks^51,75.

How close can my load get to power lines?

At least 6' 0" from 600 V–50 kV lines, with more for higher voltage (8 CCR 2946). Call the utility to verify voltage^237,259.

Who lifts the wires for a tall load?

The line owner, by arrangement. Variance route surveys must list wires and their owners, and the transporter certifies the arrangements⁷⁶.

How high are power lines over streets?

The GO 95 minimum is 18' 0" for communication lines over urban streets, and 20' 0" to 30' 0" for supply lines depending on voltage²⁵⁷.

My lowboy might hang up on a rail crossing. What's the rule?

Don't enter any rail crossing without enough undercarriage clearance or room on the far side (VC 22526)²³⁴.

Must my permit load stop at the scales?

Yes, when they are open. Cranes and fixed-load rigs too, and pilot cars cross with the load^77,246,254.

What will the officer measure?

Width, height and length against the permit (any excess is a violation), axle weights after tolerance, and exact axle spacings. Length is averaged from both sides²⁵⁴.

What happens if I'm caught off-route?

It is a statutory violation and the load may be held until a rider is issued. It is also 6 compliance points^239,254.

Do I need insurance or a bond for a Caltrans permit?

No bond and no proof of insurance normally; standard financial responsibility applies. Extra security can be required for unusually large or heavy loads^32,72.

Who pays if my load damages a bridge or sign?

The transporter is liable⁷².

Can I move at night?

It depends on the route color and width (see the route color table). Some cities require their own night-move permit⁷³.

Can I move when it's raining or snowing?

Not on hazardous surfaces, when chains are required, or with visibility under 1,000'⁷².

Where are the agricultural inspection stations on the way in?

There are 16 CDFA stations on the main highways from Oregon, Nevada and Arizona (see Entering California)²⁵⁵.

Can a farmer move a wide combine without a permit?

On its own wheels, incidentally, yes. Hauled as a load over 102 in (Interstate) or 120 in (other highways), only within 25 miles, by a farmer or farm employee carrying a signed note²⁴⁵.

Is Highway 1 through Big Sur open for deliveries?

Caltrans reported all of Highway 1 open as of January 14, 2026, and warns of occasional weather closures. Check QuickMap the day you travel^248,249.

FAQ

Oversize Permit Questions

Do I need an oversize permit for a load wider than 8 ft 6 in?

Yes. The standard legal width is 8 ft 6 in (102 inches) on the National Network. A wider load needs a permit from every state on the route, and some also need pilot cars.

What is the legal weight limit without a permit?

On the Interstate it is 80,000 lb gross, 20,000 lb on a single axle and 34,000 lb on a tandem, subject to the federal bridge formula. Non-divisible loads over that need an overweight permit.

When do I need a pilot car or escort?

Each state sets its own width, height and length triggers. The permit lists how many escorts you need and where they run, so check every state on the route.

Can oversize loads move at night or on holidays?

Most states limit oversize travel to daylight and stop wide loads on major holidays. Some allow night moves for certain sizes when the permit says so.

Who gets the permits for my load?

When you book with IZ Freight, our network of carriers handles permits, escorts and routing for each state on the lane, with IZ coordinating the move from Los Angeles.

Is this page a legal source for permit rules?

No. It is a planning guide. Rules change, so always confirm with the state permit office before a move.
