California Truck Dispatch Services

California is a headhaul state: more truck freight leaves it than comes in. In the federal Freight Analysis Framework, about 142 million tons left California by truck for other states in 2022, against about 101 million tons arriving. For owner-operators, that makes California one of the best places in the country to find an outbound load, as long as your truck meets the state's rules.

Those rules are the catch. California has its own emissions program, its own permits and a 55 mph truck speed limit. Here's what an out-of-state owner-operator needs to know, and where the freight is.

Before you run California: the rules

Check these before you book your first California load. Each one can stop a truck at a scale or a port gate.

• Clean Truck Check. The California Air Resources Board's heavy-duty inspection program covers diesel trucks over 14,000 lbs GVWR that operate in California, wherever they're registered. Trucks must be reported in CARB's system with the annual fee paid, and pass periodic emissions tests. Twice-a-year testing began in 2025. See CARB's Clean Truck Check page for your truck's schedule.
• Engine year. CARB's Truck and Bus Regulation requires most heavy trucks in California to have 2010 or newer engines. An older engine can keep you out of the state entirely.
• Motor Carrier Permit. The California DMV requires an MCP for carriers running trucks of two or more axles over 10,000 lbs GVWR in the state, with some exceptions. If you'll haul any load that starts and ends in California, read the DMV's MCP page first.
• 55 mph. Trucks with three or more axles and anything pulling a trailer are limited to 55 mph in California. Plan transit times at that speed, not 65 or 70. Our trip planner takes your average speed.
• Fuel tax. California's diesel rate on the IFTA matrix is 97.9 cents a gallon for the 4th quarter of 2026, the highest in the lower 48. Many drivers fuel in Arizona or Oregon when the route allows. The IFTA calculator shows how it nets out.

We don't tell you your truck is compliant. You do. What your dispatcher does is ask about your CARB status before booking anything that touches California, so you never accept a load you can't legally run.

Where California's freight comes from

The Port of Los Angeles alone handled 10.2 million TEUs in 2025, according to its facts and figures page. Furniture, auto parts, plastic products, apparel and electronics led its imports. Most of those containers are unloaded at warehouses inland, and that's where over-the-road trucks pick up. Port container drayage needs trucks registered in the ports' and CARB's drayage programs, so most owner-operators work the warehouse side instead.

Agriculture is the other giant. The California Department of Food and Agriculture says the state grows over a third of the country's vegetables and three-quarters of its fruits and nuts. In the FAF6 data, "other foodstuffs" is the single biggest commodity leaving California origins by truck, at about 172 million tons in 2022, with other agricultural products adding about 57 million.

California lanes: where the outbound loads go

By FAF6 tonnage, the top destinations for California truck freight are Arizona, Texas, Illinois, Nevada and Washington. That lines up with the lanes most owner-operators know:

• I-10 east to Phoenix, El Paso and Texas, the busiest way out of Southern California.
• I-15 north through Las Vegas toward Salt Lake City, and on to the northern plains.
• I-40 east from Barstow toward Albuquerque, Oklahoma City and Memphis.
• I-5 north through the Central Valley to Oregon and Washington.
• I-80 east from the Bay Area and Sacramento over Donner Summit toward Reno and Chicago.

Long outbound runs to Chicago, Dallas and the Southeast are where California pays. The return trip is the hard part. Freight heading west into California is thinner than freight heading east, so plan the reload before you deliver. Our guide on cutting deadhead covers how.

Equipment that fits California

• Reefer is California's signature freight. Produce moves almost all year as harvests shift from the Imperial Valley in winter to the Salinas Valley and Central Valley in spring through fall.
• Dry van runs on the import flow from the Inland Empire, plus packaged food and beverages from the Central Valley.
• Power only fits the big warehouse campuses, where brokers move pre-loaded trailers between distribution centers and out of state.
• Flatbed follows construction, lumber from the north and building materials. Expect tarping and tight securement checks at California scales.
• Box truck and hotshot work mostly inside the big metros and on expedited runs. Box trucks under 14,001 lbs aren't covered by Clean Truck Check, but larger box trucks are.

Seasons and weather

Caltrans posts chain levels on its truck chain requirements page. On Donner, trucks are usually required to carry link chains when controls are up. If you run I-80 in winter, carry chains that fit your drive tires. The seasonal freight calendar shows how California's harvests fit the national picture.

An Inland Empire van week through Utah and Nevada

Here's how a dispatcher might plan a week for a dry van based in the Inland Empire, with a truck that's current on Clean Truck Check. The goal is to leave on long, well-paid outbound freight and come home on shorter loads.

An example of how a week can be planned, not a promise of loads, rates or miles. Distances are rounded.

The hardest leg is the one back into California, so the plan books it before Wednesday's delivery. At 55 mph, every leg takes longer than the same miles in Arizona or Nevada, which is why we plan California runs by hours, not just miles.

California checklist: CARB, MCP, 55 mph and chains

• Make sure your truck is reported in CARB's Clean Truck Check system, the fee is paid and your periodic test is current.
• Check that your engine meets CARB's Truck and Bus Regulation before you accept the first California load.
• Plan transit time at 55 mph, the California limit for trucks pulling trailers.
• If the load starts and ends in California, check whether you need a DMV Motor Carrier Permit.
• In winter, carry chains that fit your drive tires for I-80 over Donner Summit and watch for I-5 closures on the Grapevine.

Dispatch in California with us

California freight starts with compliance, so your dispatcher checks your CARB status and engine year before the first booking. After that, the goal is a long, well-paid load out of the Inland Empire or the Central Valley, with the run home planned before you leave.
