What Commercial Auto Insurance is Required?

Any mandated commercial auto insurance limits typically apply to the liability coverage portion of the policy, but some states may require PIP and Medpay. If limit requirements are higher in the case of federally required coverage, you may have to opt for a CSL or combined single limit policy with $1 million or higher coverage, depending on vehicle use.

In short, your business insurance requirements apply to the following parts of what a commercial vehicle policy covers:

  • Bodily Injury Liability: Pays for injuries to other people when you or an employee causes an accident while driving a covered business vehicle, with limits on a per accident and per person basis.
  • Property Damage Liability: Pays for damage you cause to another person’s vehicle, building or other property in a covered accident on a per accident basis.
  • Combined Single Limit (CSL): Provides one total liability limit that can be used for both bodily injury and property damage claims from the same accident.
  • Personal Injury Protection (PIP): Pays covered medical expenses and, depending on the state, lost wages and other accident-related costs for you and your passengers regardless of fault.
  • Medical Payments Coverage (MedPay): Pays reasonable medical and funeral expenses for you and your passengers after an accident, regardless of who caused it up to a certain limit per person.
  • Uninsured Motorist (UM) and Underinsured Motorist (UIM) Coverage: Pays for covered injuries and, where available, property damage when an at-fault driver has no or insufficient auto insurance.

Federal Commercial Vehicle Requirements

Most states treat commercial and personal vehicles the same when it comes to liability minimums. But if your business falls into certain categories, you'll face much higher federal requirements from the Federal Motor Carrier Safety Administration (FMCSA):

    Interstate commerce

    Transporting goods or passengers across state lines for compensation requires motor carrier numbers (MC numbers) and higher insurance minimums. General freight carriers operating vehicles over 10,001 lbs need $750,000 minimum liability coverage.

  • Hazardous material transport

    Any business hauling hazmat faces federal oversight regardless of whether they cross state lines. These operations require $5,000,000 minimum liability coverage, making this the highest federal requirement.

    High-capacity passenger transport

    The federal government requires higher coverage for vehicles that carry multiple passengers in interstate service. Buses and vans built for 16 or more passengers need $5,000,000 liability, while smaller passenger vehicles (those that can seat between nine and 15 passengers) require $1,500,000.

Federal requirements can change and may have additional conditions. Consult with FMCSA or a commercial insurance specialist for current regulations affecting your specific business operations.

Federal liability requirements represent minimum coverage amounts and don't include deductibles, which vary by insurer and policy terms.

Is Minimum Commercial Auto Insurance Enough?

Minimum commercial auto insurance rarely provides adequate protection for most businesses. Some states only require $25,000 per person, which may not be sufficient protection. The Centers for Disease Control and Prevention (CDC) put the average cost of medical bills from motor vehicle accidents at $14,126 in 2023. Severe cases requiring hospitalization can cost much more.

Commercial Auto Insurance Requirements: Bottom Line

Commercial auto insurance requirements vary by state and business type, with most states requiring liability coverage ranging from $15,000 to $50,000 per person for bodily injury, while businesses using vehicles commercially need coverage that exceeds personal auto policy limits.

Most small businesses should buy more than state minimums and consider general liability coverage plus industry-specific protection. Obtain coverage by gathering documentation on your vehicles and drivers, then work with insurers to get the required certificates for compliance and comprehensive protection.
