Flatbed trucking in California

What rides on a flatbed in California

A lot of what California builds with will not fit through trailer doors. Structural steel, rebar and lumber go to new housing tracts from Riverside County up to the Central Valley. Machinery and steel products that land at the Long Beach and Los Angeles harbors leave on open decks for plants inland. Out in the deserts, solar racking, inverters and battery storage enclosures head to project sites in the Imperial Valley and the Coachella Valley.

Farm country needs open decks too. Irrigation pipe, pumps, tractors and harvest equipment move between dealers and growers around Fresno, Visalia and the Salinas Valley. Data center builders in the state call for flatbeds and step decks to bring generators, switchgear and transformers to site, which our West Coast data center flatbed page explains.

California rules a flatbed load has to meet

Width is the first number we check. Any vehicle or load wider than 8 feet 6 inches needs a transportation permit from Caltrans. Height tops out at 14 feet, and a load over 13 feet 6 inches may only use roads where the driver has judged the clearance safe, so a tall piece often rides on a step deck instead.

A 53 foot flatbed is legal on the national truck network and the terminal access routes as long as the kingpin sits no more than 40 feet ahead of the rear axles, or 38 feet with a single axle. Some cities and counties hold that distance to 38 feet on their own streets. Gross weight without a permit is 80,000 pounds, with 20,000 pounds on a single axle and 34,000 on a tandem.

Permit loads wide enough for a pilot car follow the Caltrans route colors. On the least restrictive yellow routes that means one pilot car over 12 feet wide, two over 15 feet and a Highway Patrol escort over 16 feet, and those loads come off the road for the afternoons and evenings around the major holidays. Every truck pulls into Highway Patrol scales when the signs say so, and loads entering from Arizona, Nevada or Oregon pass agricultural inspection stations that check for pests.

Where we run flatbeds in California

Two open deck lanes into the state are ones we regularly book: out of Phoenix west across the desert on Interstate 8 to San Diego County, and out of Phoenix to Salinas on the Central Coast. Both have their own pages, Phoenix to San Diego and Phoenix to Salinas. Several times a year flatbeds also come west from Phoenix to Riverside and San Bernardino counties and to Los Angeles County, south from Salinas toward Los Angeles, and down from the Bay Area on the San Francisco to Los Angeles lane.

Inside the state we quote open deck loads out of Stockton, Modesto and Bakersfield to Long Beach, Fontana and Victorville, and north to Redding and Eureka near the Oregon line.

Passes, chain controls and summer heat

When California posts chain controls, trucks over 6,500 pounds must mount chains on a drive axle and on a braked trailer axle, and snow tires do not excuse them. For flatbeds in and out of Southern California the passes that matter are Interstate 5 over Tejon Pass, Interstate 15 over Cajon Pass and State Route 58 near Tehachapi. Farther north, Interstate 80 over Donner Pass, US 50 over Echo Summit and Interstate 5 north of Redding see chain controls through the winter.

Summer brings the other problem. In the Imperial and Coachella valleys and along Interstate 10 toward Blythe, afternoon heat is hard on tires and on crews unloading by hand, so early appointments help. Wind advisories in the passes and the high desert can also slow a tall or light load until the gusts drop.

What our dispatcher needs to book it

Give us each piece’s length, width and height, the heaviest item and the gross weight, plus how it loads: forklift from the side, overhead crane, or a dock. Tell us whether it needs tarps (lumber tarps, steel tarps or a smoke tarp across the front of the load) and whether the receiver has a forklift or a crane on site.

Enter those details on the quote form along with both cities and the dates. One dispatcher keeps the load from your first call to the signed delivery receipt, confirms the carrier’s straps, chains and edge protection suit the freight, and sends the paperwork when the receiver signs.
