Coverage

Primary Auto Liability Insurance for Trucking

Primary auto liability is the coverage that pays third parties when you hurt someone or damage their property with your truck. It's required by FMCSA before you can run under your own MC number, and the federal minimums depend on what you haul.

What Primary Auto Liability Insurance Covers

  • Bodily injury you cause to other drivers, passengers, or pedestrians in an at-fault accident
  • Property damage to other vehicles, guardrails, buildings, or anything else you hit
  • Legal defense costs if you're sued after a covered accident, including attorney fees
  • Settlements and judgments up to your policy limit, typically $750,000 or $1 million
  • Federally filed financial responsibility under your MC number (the MCS-90 endorsement)
  • Medical payments for injured third parties on most policies, up to a sub-limit

Common Exclusions

  • Most policies exclude damage to your own truck and trailer — that's what physical damage covers
  • Typical exclusions include damage to the freight you're hauling — that requires motor truck cargo
  • Most policies exclude injury to your own employees or drivers — workers comp or occupational accident handles that
  • Typical exclusions include intentional acts, hauling outside your filed radius, or operating without a valid CDL
  • Most policies exclude personal, non-business use if you're leased on — that needs non-trucking liability
  • Specific exclusions vary by carrier; always read your declarations page before assuming a loss is covered
Exclusions vary by carrier. Always review your policy declarations and exclusions schedule before binding.

Who Needs Primary Auto Liability Insurance?

If you run under your own MC number, primary auto liability isn't optional. FMCSA won't activate your authority without a Form MCS-90 or BMC-91 filing from a licensed insurer. Own authority operators must carry at least $750,000 for general freight, $1 million for most hazmat and auto-haulers, and $5 million for certain bulk hazardous materials. Leased-on drivers usually don't buy this — the motor carrier they pull for provides primary coverage while under dispatch. If that's you, see leased-on operators for what you actually need to carry.

What Primary Auto Liability Insurance Costs

Primary Auto Liability Insurance typically runs $8,000–$20,000+ per year for new authority owner operators.

Driving record, years in operation, radius of operation, and commodities all move the premium. New authority typically costs more than established carriers.
