Operating a truck in California means complying with both federal FMCSA regulations and a separate layer of state-specific requirements. Here's what you need to know heading into 2026.

Advanced Clean Fleets and CARB compliance

California's Advanced Clean Fleets regulation is the biggest regulatory shift in years. The California Air Resources Board (CARB) is phasing in requirements for zero-emission vehicles in certain fleet categories. While the full mandate doesn't take effect for all fleets immediately, 2026 brings new reporting requirements and compliance milestones for high-priority and federal fleets.

If you operate drayage trucks at California ports or railyards, you're already subject to zero-emission requirements that are tightening this year. Check the CARB Advanced Clean Fleets page for your specific compliance timeline.

AB5 and independent contractors

Assembly Bill 5 (AB5) remains a factor for California trucking operations, though the landscape continues to evolve through court challenges and exemptions. The core issue: California applies the ABC test to determine whether a worker is an employee or independent contractor, which is stricter than the federal standard.

For motor carriers, this affects how you engage owner-operators. While federal preemption arguments have had some success in court, the legal situation remains unsettled. If you use independent contractors in California, make sure you understand the current state of the law and consult with a transportation attorney if needed.

California Motor Carrier Permit (MCP)

Every motor carrier operating in California — including interstate carriers — must hold a valid California Motor Carrier Permit (MCP) issued by the DMV. This is separate from your federal operating authority. The MCP requires proof of California-compliant insurance, and penalties for operating without one are steep.

If you've recently started operating in California or your permit has lapsed, you can apply through the California DMV Motor Carriers page.

BIT inspections

California's Biennial Inspection of Terminals (BIT) program requires motor carriers based in California to have their vehicles, maintenance records, and driver files inspected every 25 months by a CHP-authorized inspector. Your terminal gets a satisfactory or unsatisfactory rating, and an unsatisfactory rating can lead to enforcement action.

If your BIT inspection is coming up in 2026, start preparing now — make sure maintenance records are complete, driver qualification files are current, and vehicles are in compliance.

Key deadlines and filings

  • UCR registration — Due annually. Check ucr.gov for the current filing period.
  • IFTA quarterly filings — Due the last day of the month following each quarter (April 30, July 31, October 31, January 31).
  • IRS Form 2290 (HVUT) — Due August 31 annually for trucks over 55,000 lbs.
  • MCS-150 updates — Required every 24 months or when your operation changes.

Stay compliant, stay insured

Regulatory compliance and insurance go hand in hand. A lapsed MCP or a failed BIT inspection doesn't just mean fines — it can affect your insurability.
