Los Angeles trucking companies follow FMCSA safety rules for interstate work and California’s own rules, enforced by the CHP, for trucks that run in the state.
Our team helps carriers set up and keep what both require, from the CA number and motor carrier permit to driver files, drug testing, and inspection records, so they are ready for an audit.
The federal rules apply when you run a commercial motor vehicle in interstate commerce. Under 49 CFR 390.5T, that is a vehicle of 10,001 pounds or more, one that carries more than 8 passengers (including the driver) for pay or more than 15 without pay, or one hauling hazardous materials in placarded amounts.
The federal definition of interstate commerce includes transportation between two places in one state “as part of trade, traffic, or transportation originating or terminating outside the State or the United States.” An import container moving from a San Pedro Bay terminal to a warehouse in the Inland Empire can fall under the federal rules even though the truck never leaves California.
California reaches more trucks than the federal rules do. Anyone paid to haul property, and generally anyone running a commercial vehicle of 10,001 pounds or more, even for their own goods, needs a DMV motor carrier permit (MCP). Behind it sit a USDOT number and a California carrier identification number (CA#) from the CHP. Your trucks must show the CA# on both sides unless they display a valid USDOT number, as our guide on how to mark a commercial motor vehicle explains.
Two more differences affect hiring and logs. California lets drivers aged 18 to 20 drive for pay inside the state, but not in interstate commerce or with hazardous materials. And since January 1, 2024, intrastate drivers must record their hours on an electronic logging device unless an exemption applies.
Our California DOT compliance page covers the state rules in full, and our California motor carrier permit service handles the CA# and the MCP.
The ports. Los Angeles and Long Beach share the San Pedro Bay port complex, and much of the region’s truck work is drayage between its terminals, rail yards, and warehouses.
Under the port’s Clean Truck Program, every licensed motor carrier making regular calls at its cargo terminals needs an approved concession agreement, and every truck entering a marine terminal must be listed in the Ports Drayage Truck Registry. Since October 1, 2018, new registrations of trucks entering service there must be model year 2014 or newer.
Carriers that move cargo through the port 24 times a year or less can use a temporary access permit instead of a concession, as long as their trucks meet the program’s requirements.
State emissions rules apply on top. Drayage trucks must comply with California’s drayage truck law, and under CARB’s Truck and Bus regulation, diesel vehicles over 14,000 pounds operating in California have needed a 2010 or newer engine since January 1, 2023, with few exceptions. The DMV denies registration to trucks that don’t comply. Our Los Angeles commercial truck insurance page explains the coverage the port concession requires.
Inside the Overweight Container Corridor, permits allow a gross vehicle weight of 95,000 pounds for the truck, chassis, container, and contents, with proper equipment. Each agency on the route issues its own permit, so a trip through several cities on the corridor map needs a permit from each one.
Your vehicles and your records. Under California’s Basic Inspection of Terminals (BIT) program, carriers that run truck tractors, trucks with three or more axles over 10,000 pounds, commercial vehicles of 26,001 pounds or more, and certain other vehicles, such as placarded hazmat trucks, must tell the CHP about every California terminal where those vehicles and their maintenance and driver records can be inspected.
The CHP picks terminals through a performance-based system and gives priority to terminals it has never inspected. The sample depends on fleet size, counted separately for power units and trailers: every vehicle in a fleet of one or two, up to 20 in a fleet of 91 or more. A carrier that doesn’t make vehicles and records available gets an unsatisfactory rating.
The same vehicles must be inspected at least every 90 days under Vehicle Code 34505.5. The inspection covers brake adjustment, brake components and leaks, steering and suspension, tires and wheels, and connecting devices. Defects must be fixed and signed off before the vehicle runs again, except to a place of repair, and the records stay at your terminal for two years.
An unsatisfactory terminal rating brings a reinspection within 120 days and can lead to a suspended MCP. Trucks in interstate commerce also need the federal annual inspection under 49 CFR 396.17, at least once every 12 months, with proof carried on the vehicle.
Five sets of records. A new carrier is monitored for 18 months, and FMCSA runs a safety audit once it has operated long enough to have records to review, generally at least 3 months (49 CFR 385.307). The audit covers:
Some violations fail the audit on their own. 49 CFR 385.321 lists 16, including having no drug and alcohol testing program, operating without the required insurance, and knowingly using a driver without a valid CDL. If you fail, you have 60 days to fix the problems, or 45 days if you carry passengers or placarded hazmat, before your registration is revoked (49 CFR 385.319).
Our new entrant safety audit checklist walks through each record, our DOT safety compliance page explains what each program requires, and our audit guidance and support service prepares you and stays with you through the audit.
Our California office is at 8560 Vineyard Ave, Suite 112, in Rancho Cucamonga, and we support carriers across the country. Our compliance programs come in three levels:
Across the programs, the work ranges from driver qualification file management and CSA monitoring to mock audits and hours-of-service management. We also handle trucking permits, IFTA, UCR, and commercial truck insurance, so your paperwork, filings, and coverage stay in step.
Use the form below to tell us about your company. Include your USDOT number, or let us know you don’t have one yet, and our team will follow up with the right program.
Yes. Our California office is at 8560 Vineyard Ave, Suite 112, Rancho Cucamonga, CA 91730. We also have offices in Miami, Houston, and Richardson, near Dallas.
They keep a carrier’s FMCSA and state records in order: driver qualification files, drug and alcohol testing, hours of service, and vehicle maintenance and inspections. Ours also include CSA monitoring, mock audits, and support during a DOT audit.
Most need a USDOT number, a CA number from the CHP, and a DMV motor carrier permit, which requires proof of insurance and proof of workers’ compensation or a signed exemption. Carriers that employ commercial drivers also need an Employer Pull Notice requester code.
Yes, if they need a CA number. The CHP won’t assign a CA number without a USDOT number, and FMCSA lists California among the states that require one from intrastate commercial vehicle registrants.
