What Commercial Auto Insurance Is Required in Michigan?

Michigan's commercial auto insurance requirements for most businesses are:

  • $250,000 for bodily injury or death of one person per accident
  • $500,000 for bodily injury or death of two or more people per accident
  • $10,000 for property damage per accident

Every Michigan commercial auto policy must also include personal injury protection (PIP) and property protection insurance (PPI) under the state's no-fault law. Coverage minimums increase based on vehicle weight, passenger capacity, cargo type and whether operations cross state lines.

Michigan Commercial Auto Insurance Alternatives

Michigan issues self-insurance certificates to commercial fleets with more than 25 registered vehicles, a net worth above $15 million and approval from the Department of Insurance and Financial Services (DIFS) under MCL 500.3101d. Self-insured businesses must still comply with all no-fault PIP, PPI and bodily injury requirements, including the $250,000/$500,000 default liability limits.

Michigan does not allow cash deposits or surety bonds as alternatives to commercial auto insurance for standard operations. Businesses that don't qualify for self-insurance must carry a standard commercial auto policy.

Special Michigan Commercial Auto Insurance Coverage Circumstances

Beyond standard liability, four Michigan-specific situations require additional coverage or separate documentation:

    Leased commercial vehicles

    Michigan leasing companies either add the lessee to the lessor's own policy or require the lessee to carry coverage at Michigan's $250,000/$500,000/$10,000 default limits or higher. Michigan's liability minimums won't cover the remaining lease balance if the vehicle is totaled. Gap insurance bridges the difference between the vehicle's actual cash value and what you still owe, which matters most on newer trucks and vans where depreciation outpaces payoff.

    Canada Border Commerce

    A Michigan commercial auto policy doesn't automatically provide full protection once you cross into Ontario. If your vehicles use the Ambassador Bridge, Blue Water Bridge, Gordie Howe International Bridge or the Sault Ste. Marie crossing, confirm with your insurer that your policy extends into Canada and satisfies Ontario's C$200,000 minimum liability threshold. The U.S. Department of State's Canada travel advisory lists current entry and documentation requirements for commercial operators.

    No-Fault PIP Coverage Elections

    Michigan's 2019 no-fault reform (Public Acts 21 and 22) introduced a menu of PIP medical coverage options, from unlimited benefits down to a complete opt-out for drivers with qualifying health insurance. Fleet operators should track which PIP level applies to each vehicle, because under MCL 500.3135(3)(c), the at-fault party is now liable for a victim's medical costs above the victim's PIP cap. A lower PIP election can reduce premiums but increase lawsuit exposure.

    Farm Vehicles on Public Roads

    Michigan farm tractors and implements of husbandry are exempt from registration under MCL 257.216 as long as they stay off public highways. The moment you operate agricultural equipment on a road, Michigan's full no-fault insurance mandate applies. Operating an uninsured farm vehicle on a public road is a misdemeanor. If your operation moves farm machinery between properties on public roads, carry a commercial auto policy that covers those vehicles during transit to avoid a misdemeanor charge and loss of no-fault benefits.

Michigan Commercial Auto Insurance Enforcement and Penalties

Officers in Michigan can verify insurance status at any traffic stop and file charges on the spot if the driver can't produce proof of coverage. The Secretary of State's office also monitors insurance-to-registration records and can cancel plates on vehicles that show a coverage lapse.

Failure to produce proof
Up to $50 civil infraction
None
Court may order license surrender; $25 assessment fee
No insurance (first conviction)
$200–$500
Up to 1 year
License suspended until proof of coverage; plates may be canceled
No insurance (subsequent convictions)
$200–$500
Up to 1 year
Extended suspension; reinstatement fee of $125+

Reinstatement after a suspension for no insurance requires an SR-22 filing with the Michigan Secretary of State, kept active for three to five years depending on the violation. Under MCL 500.3135(2)(c), an uninsured vehicle owner in Michigan loses the right to recover no-fault PIP benefits and can't sue for pain and suffering, even when not at fault.

How to Verify Your Business Meets Michigan Commercial Auto Insurance Requirements

Use these checks for every vehicle in your fleet to confirm you're meeting Michigan's state and, where applicable, federal insurance rules.

  1. 1

    Identify how each vehicle is used

    Michigan's coverage tier depends on the vehicle's function, so confirm whether each vehicle hauls freight, carries passengers, serves a job site or just moves employees between locations. A commercial policy isn't required if the vehicle is only used for occasional work errands, unless it's titled to the business or used regularly for business purposes.

  2. 2

    Check each vehicle's weight rating

    Look up the GVWR on the driver-side door sticker. Any vehicle rated at 10,001 lbs or above may trigger federal FMCSA insurance obligations that exceed Michigan's state-level defaults.

  3. 3

    Determine whether state or federal rules apply

    Federal FMCSA minimums replace Michigan's limits whenever your vehicles carry cargo or passengers across state lines. This includes operations where your leg stays within Michigan but the shipment is part of a broader interstate route.

  4. 4

    Confirm your liability limits meet the correct requirement

    Michigan's default is $250,000/$500,000/$10,000. For-hire passenger carriers and interstate freight haulers must meet thresholds of $1,500,000 to $5,000,000 CSL depending on seat count, cargo type and vehicle weight.

  5. 5

    Verify your PIP and PPI elections

    Every commercial auto policy in Michigan must include PIP and property protection insurance. Review which PIP medical coverage tier you've selected for each vehicle, especially if your fleet has mixed elections across different trucks or vans.

  6. 6

    Confirm your policy reflects actual vehicle use

    Cross-check that your Michigan policy classifies each vehicle correctly, lists all regular drivers and matches coverage to how the vehicle operates day to day.

  7. 7

    Check for Canada border coverage gaps

    If any of your vehicles cross into Ontario, verify that your policy provides liability coverage in Canada and meets Ontario's C$200,000 threshold.

Michigan Commercial Auto Insurance Requirements: Bottom Line

Your required coverage in Michigan depends on vehicle weight, passenger capacity, cargo type, PIP elections and whether your routes cross state lines or the Canadian border. Verify that each vehicle's policy limits, use classification and no-fault elections line up with the specific requirement tier that governs how that vehicle operates.

Michigan Commercial Auto Insurance Requirements: Next Steps

Michigan's legal minimums set the least amount of coverage the law allows. What your business needs depends on your exposure, which often runs higher than the statutory floor.
