All 48 states · Agency of CRST · Asset-based capacity
Vector Logistics moves flatbed, heavy haul, and oversize freight in all 48 states as an agency of CRST. This is the California chapter: Caltrans permits, the strictest escort and curfew rules in the West, CARB-compliant equipment, the Grapevine and Donner, the ports, and what a load moving into, out of, or across California will actually need.
Heavy haul in California
California is the state where national brokers get burned. Caltrans permits are not expensive, but the rules attached to them are the strictest in the West: escorts at lower widths than neighboring states, no oversize travel on weekends and holidays for larger loads, curfews in every metro, and a trucking fleet that has to meet CARB emissions rules just to be on the road. A load that runs routine through Arizona and Nevada can be a two-escort, weekday-only, daylight-only move the moment it crosses the state line.
I have pulled oversize through the Grapevine and down the Cajon, and I know which of those rules bind on which lanes. Vector Logistics quotes California on the real route with the real escort count and the real travel windows, with CRST's asset-based, CARB-compliant capacity behind every load.
The numbers
Standard limits on California highways. The numbers are ordinary; the escort and travel-time rules attached to anything over them are not.
| Dimension | California legal limit | Over that means |
|---|---|---|
| Width | 8 ft 6 in | Over-width permit. One pilot car generally required over about 12 ft on two-lane routes and in many metro areas, two pilots as width increases; California adds escorts earlier than most neighboring states. |
| Height | 14 ft | Over-height permit. Route clearance is checked structure by structure; many older urban routes have lower postings. Height-pole escort at larger heights. |
| Length | 53 ft trailer on the designated network, 65 ft combination | Over-length permit. Rear pilot on mountain and two-lane routes; California's kingpin-to-rear-axle rules also restrict what trailers can go where. |
| Gross weight | 80,000 lb | Overweight permit. California is strict on axle weights and bridge formula; heavy moves are routed around restricted structures and may need engineering review above roughly 250,000 lb. |
| Axle weight | 20,000 lb single, 34,000 lb tandem | Permit tables allow more with spacing; California enforces at the scale, not on paper. |
Add to that the CARB rules: most heavy trucks operating in California must meet model-year and emissions requirements and be enrolled in Clean Truck Check. A carrier that is fine in Idaho may not be legal to enter California at all. Every truck we put on a California load is compliant; that is part of what CRST's network gives us.
Permits and escorts
Permits come from the Caltrans Transportation Permits office. Routine single-trip permits are issued quickly and are inexpensive. The operating rules are where California is different:
Roads
The spine from the Oregon line to San Diego. The Tejon Pass (the Grapevine) between the Central Valley and LA is a long grade with winter closures and wind holds for tall loads. North of Sacramento it is open and easy; through the Bay Area feeder routes and the LA basin it is curfews and night windows.
The main route east to Reno and on to Salt Lake. Chain controls and closures in winter, construction in summer, and oversize restrictions over the summit. Loads from the Northwest headed to Nevada often avoid it by running US-97 and US-395 or I-84 to I-80 through Utah.
LA and the Inland Empire to Las Vegas. Cajon is a heavy truck grade with its own oversize windows, and the Inland Empire warehouse corridor is curfew territory. The most common route for Southern California to Nevada, Utah, and Arizona heavy haul.
I-10 out of LA through Palm Springs to Blythe; I-40 out of Barstow to Needles. Both open and oversize-friendly once clear of the metro. Wind holds near Palm Springs for high-profile loads.
Bakersfield, Fresno, Modesto, Stockton. Ag equipment, food processing, and solar and energy construction. Lower structure clearances on older sections than I-5, so tall loads get routed carefully.
Narrower, slower, and restrictive for wide loads through the coastal towns. The right route for some Bay Area and Central Coast destinations, rarely the right through-route.
Who ships here
Why Vector
California is the state most likely to turn a routine oversize move into a missed delivery, and the reasons are all knowable in advance: escort count, travel window, curfew, CARB compliance, routed permit. We know them because we have run them. Every California load Vector Logistics books runs on CRST's compliant, asset-based network with CRST's cargo insurance behind it, and one person accountable for the plan from pickup to delivery, whether that pickup is in Long Beach or Lewiston.
Typical California heavy haul move: 336-class excavator, 11 ft wide, 12 ft 6 in travel height, 84,000 lb, Salem, OR to Bakersfield, CA. Routine permits in Oregon, then California: over-width and overweight permit, one pilot car on parts of the route, weekday daylight travel only, CARB-compliant carrier required. Three days instead of two, and the escort is the cost difference.
The same machine to Reno instead of Bakersfield runs without an escort. Destination state changes the move.

Questions we get
Caltrans requires pilot cars at lower widths than neighboring states, restricts larger oversize loads from moving on weekends and holidays, enforces peak-hour curfews in every major metro, routes permits around restricted bridges, and requires trucks to meet CARB emissions rules. None of it is unmanageable, but all of it has to be planned before the truck is dispatched.
As a general rule, one pilot car over about 12 feet wide on two-lane routes and in many urban areas, with a second as width increases, plus escorts for over-length loads on mountain routes and height-pole escorts for tall loads. Thresholds are lower than Arizona, Nevada, or Texas, so a load that runs without an escort in those states often needs one in California.
Larger oversize loads generally cannot move on weekends or on and around holidays in California. Smaller permit loads have more flexibility. We build California schedules on weekday daylight windows and tell you up front what that does to transit time.
CARB is the California Air Resources Board. Heavy trucks operating in California must meet engine model-year and emissions requirements and be enrolled in the Clean Truck Check program. A carrier that is not compliant cannot legally run your load in the state. Every truck we put on a California move is compliant.
14 feet on most state highways and Interstates. Over 14 feet requires an over-height permit and a structure-by-structure clearance check, and older urban routes frequently have lower postings.
Yes. Project cargo, machinery, and transformers out of LA, Long Beach, and Oakland to sites across the West are regular moves, with CRST's asset-based capacity and cargo insurance behind them. We also handle the interstate leg into Arizona, Nevada, Oregon, and beyond on the same quote.
