Michigan Commercial Trucking Insurance

Trucking Insurance Requirements in Michigan: Interstate vs Intrastate

Which rules apply to you depends on where you run, not on what you drive. If you cross state lines, federal rules apply and your filings go to FMCSA. If you operate only inside Michigan, the state's own limits and filings apply instead, through the Michigan State Police, Commercial Vehicle Enforcement Division (CVED), Regulatory and Credentialing Section. If you do both, you follow whichever insurance requirement is higher.

Michigan writes the federal rules into state law. Under MCL 480.11a the state adopts 49 CFR parts 40, 382, 383, 385, 387, 390 through 393 and 395 through 399, and reads the word interstate in those rules as intrastate or interstate. That adoption covers intrastate vehicles that meet the federal commercial motor vehicle definition in 49 CFR §383.5, meaning a single unit or combination rated at 26,001 lbs or more, or a vehicle of any size hauling placarded hazardous materials. Lighter intrastate trucks still answer to the driver qualification, driving and equipment rules in parts 391 through 393. One Michigan-specific carve-out runs the other way: under MCL 480.15, an intrastate carrier's drivers in seasonal construction-related work may not operate more than 12 hours or be on duty more than 16 hours in a day, on a 70-hour, 7-day or 80-hour, 8-day cycle.

Intrastate for-hire authority has no weight floor. The Motor Carrier Act bars a carrier of general commodities from running for hire on any Michigan public highway without a certificate of authority, whatever the truck weighs. Weight matters in two other places. The Michigan State Police asks for a USDOT number on units over 26,001 lbs, and the federal rules Michigan adopts, including the Part 387 insurance schedule, attach to intrastate vehicles at that same commercial motor vehicle line.

The Michigan sequence is set by statute and by the CVED checklist. Applications go through the online CVED Authority Portal only. Before approval you need a USDOT number if any unit is over 26,001 lbs, your business registered with the state or county clerk, proof of workers' compensation insurance or an approved exclusion form from the Workers' Compensation Agency, and a certificate of liability plus a Form E from your insurer. Under MCL 479.9 the carrier has to demonstrate workers' comp compliance at initial application, so comp is part of getting authority here, not something to sort out later. Processing can take up to 30 days, and an application missing documents at that point is dismissed. The certificate is also a calendar-year credential: under MCL 479.10 it ends December 31, renewal runs from October 1 to December 1, and a carrier that has not renewed with proof of insurance is canceled on January 1 and may not operate its vehicles.

Minimum Insurance Requirements in Michigan

Interstate carriers operating in Michigan meet the federal minimums set in 49 CFR §387.

Michigan intrastate minimums

The first three rows come from the federal schedule at 49 CFR §387.9, which Michigan adopts for intrastate commercial motor vehicles. For lighter for-hire trucks under 26,001 lbs, CVED still requires a Form E before it grants authority, but the dollar figure behind that filing is not published in the statute, so confirm it with CVED before you quote a light-truck operation. Household goods movers also need a Form H for cargo. The last two rows apply to every truck registered in Michigan, for-hire or not, because MCL 500.3101 makes no-fault coverage part of the registration obligation. For a for-hire carrier the federal limit already sits above the residual liability defaults in MCL 500.3009; the no-fault row is the one that changes how the policy is built.

The legal minimum and the practical minimum are rarely the same number. The federal requirement for general freight is $750,000, but many brokers and shippers will not tender a load without $1,000,000 in auto liability and $100,000 in cargo coverage. See the coverages we offer for what sits inside each of those limits.

Insurance Filings and Registration in Michigan

Federally, your insurer, not you, files the BMC-91 or BMC-91X electronically with FMCSA. The MCS-90 is the related endorsement attached to the policy itself rather than a separate filing. Neither is something the operator submits directly.

In Michigan, the liability filing is Form E, with Form H (household goods carriers) for cargo, filed with Michigan State Police CVED, filed by your insurance company and matched to your CVED number. Intrastate-only carriers, household goods carriers and wreckers doing police-initiated tows apply for CVED Authority through the online CVED Authority Portal, buy a decal for each vehicle, and renew every year from October 1 to December 1.

CVED's checklist asks for a certificate of liability and a Form E from your insurer. The certificate you can print is not the filing; the Form E is what CVED records against your authority. Household goods carriers add a Form H.

Interstate carriers are not exempt from CVED entirely. A UCR-registered carrier hauling point to point inside Michigan needs its insurance filings, paid UCR, business registration and proof of workers' comp or an exclusion form. It does not renew annually as long as UCR stays current, but the Motor Carrier Act revokes the intrastate authority of a UCR carrier that has not renewed UCR by January 1.

Under MCL 479.8 each intrastate vehicle carries a CVED-issued cab card and displays the decal, and power units show the carrier's name, city and state on both sides. A vehicle marked to 49 CFR §390.21 meets the name requirement. The statute also calls for the carrier's state account number and a separate unit number on both sides of each power unit, and those markings come off when a vehicle leaves the authority.

Added equipment cannot run until its decal and cab card have been issued and attached, so add a truck to CVED before it goes to work rather than after, and add it to your policy the same day.

The two moments that matter are the ones people get wrong. With new authority, the filing usually has to be completed before the authority becomes active, so the policy comes first, not last. When switching insurers, the old filing is replaced by the new one, and the whole job is making sure there is no gap between them. We sequence both filings as part of binding the policy, so the state record never shows a gap. Get a Michigan quote.

What Commercial Truck Insurance Costs in Michigan and What Drives It

Three things do more than anything else to shape a Michigan truck quote, and the first one exists because of how the state's auto insurance law is built.

Beyond that, a Michigan rate moves on what an underwriter checks anywhere: your operating radius, what you haul, the age and value of the equipment, the driving records of the people behind the wheel, and how long the authority has been active.

Your overall profile decides how many markets will quote a Michigan risk at all. Recent violations, an authority under a year old, or thin driving history shrink the list of willing insurers, and adding hazmat, heavy haul or cross-border work shrinks it again. That is a market-access problem first and a price problem second.

How Michigan Law Affects Your Coverage

Michigan uses modified comparative fault under MCL 600.2959. Damages are reduced by the injured person's share of fault, and if that share is greater than the combined fault of everyone else, economic damages are still reduced but noneconomic damages are not awarded at all. The no-fault statute says the same for auto cases: under MCL 500.3135 noneconomic damages are not assessed in favor of a party more than 50% at fault. For a carrier, the fault split decides both whether a pain-and-suffering claim survives and how much of it you pay, which is why dash-cam and telematics evidence carries real weight in a Michigan claim.

Michigan is a no-fault state, and a truck policy here is built around it. Under MCL 500.3101 the owner or registrant of a vehicle required to be registered in Michigan maintains personal injury protection, property protection insurance and residual liability while the vehicle is driven on a highway. PIP pays allowable medical expenses up to the level selected under MCL 500.3107c, plus work loss and replacement services. Property protection insurance under MCL 500.3121 pays for damage the truck does in Michigan to other people's property, such as buildings, fences and properly parked vehicles, up to $1,000,000 per accident under one policy, without regard to fault. In exchange, MCL 500.3135 limits lawsuits: an injured person sues for pain and suffering only after death, serious impairment of body function or permanent serious disfigurement, and can still sue for medical and wage losses above their own PIP level. Damage to a moving vehicle is handled by collision coverage and a small-claims mini-tort action of up to $3,000.

Uninsured and underinsured motorist coverage is optional in Michigan. MCL 500.3101 requires PIP, property protection insurance and residual liability, and the Department of Insurance and Financial Services lists those three as the mandatory coverages. UM and UIM are not among them, so they may be absent from a Michigan policy unless you ask. PIP still pays your medical and wage benefits after a crash with an uninsured driver, which is why UM here mainly matters for the pain-and-suffering claim you could otherwise not collect on. Check the declarations page rather than assuming.

PIP, uninsured motorist and the rest of the stack are explained in full in our guide to what each coverage pays for and when.

How Michigan no-fault changes a truck policy

Start with who pays for injuries. Under MCL 500.3114, an employee hurt while riding in a vehicle owned or registered by the employer collects PIP from the insurer of that vehicle, so a fleet's own policy is first in line for its employee drivers. Benefits paid under state or federal law, workers' compensation included, are subtracted from PIP under the same chapter, which is why comp and PIP have to be read together rather than bought in isolation.

Then look at your own truck and freight. The statute abolishes most tort liability for damage caused by an insured vehicle in Michigan, and property protection insurance does not pay for damage to moving vehicles or what is in them. Read together, MCL 500.3135 and the property protection exclusions generally leave a trucker whose rig is hit by an insured driver in Michigan with a mini-tort claim of up to $3,000 for damage not covered by insurance, and not much more. For a tractor and trailer worth far more than that, collision and cargo coverage are what actually pay. This is informational, not legal advice; ask your own attorney how it applies to a specific loss.

Out-of-state trucks sit differently. A nonresident owner who operates a vehicle not registered in Michigan for more than 30 days in a calendar year has to maintain Michigan security under MCL 500.3102. A nonresident who does not own a Michigan-registered, Michigan-insured vehicle is generally not entitled to Michigan PIP, and a nonresident can sue for economic loss only after meeting the serious-injury threshold. If you are based elsewhere and run Michigan regularly, ask how your policy answers a Michigan loss before you have one.

Finally, lapses bite harder here. An owner of a vehicle without the required security is not entitled to PIP, cannot collect noneconomic damages or mini-tort for injuries or damage while driving that vehicle, and loses the tort protection that insured vehicles get. Operating without security is also a misdemeanor.

Frost laws and Michigan weight limits

Michigan's weight law works from axle loads and axle spacing under MCL 257.722. The interstate system carries an 80,000 lb gross limit with the federal bridge formula, while off the interstate, vehicles above that gross weight are held to the state's per-axle maximums instead. That makes the axle configuration on a unit matter as much as its gross weight.

Every spring, seasonal restrictions cut those limits. The statute names March, April and May and reduces maximum axle loads by 25% on concrete or concrete-base pavement and 35% on other roads, with lower per-inch tire loads too. MDOT and local road agencies can impose or lift restrictions when conditions warrant, and MDOT sets its own dates from frost-depth measurements, so the real start and end come from MDOT bulletins, the Truck Operators Map and county road commission postings rather than from the calendar. Local restrictions can differ from state routes.

There are carve-outs that matter to specific operators. Haulers of agricultural commodities picking up from or delivering to a farm can get a county road commission permit for county roads that lifts the seasonal reduction with 48 hours' notice. Milk haulers can ask for route exemptions. A propane delivery truck to a residence is exempt when its tank is no more than half full and it stays at or under 35 mph. Agricultural commodities and raw timber moving from harvest or farm storage to the first delivery point also get a 10% higher axle load, but not on interstates and not on restricted roads during frost-law season.

The insurance side is indirect but real. Frost-law season compresses spring hauling into fewer legal routes and lighter loads, which tends to add trips, detours and schedule pressure. An overweight citation is not an insurance matter, but the rerouting, extra trips and rushed scheduling around it are where losses come from.

Cross-border freight at Detroit and Port Huron

Michigan's crossings into Ontario, including the Ambassador Bridge at Detroit and the Blue Water Bridge at Port Huron, make Canadian miles part of the job for some Michigan carriers. The state's no-fault law treats the two sides of the border differently. Under MCL 500.3111, PIP benefits follow a covered person into accidents elsewhere in the United States and in Canada. Property protection insurance does not travel: it is not payable for property damage from accidents outside Michigan.

What carries you once you are in Canada is your liability and physical damage coverage, and whether the policy territory includes Canada is a policy question, not a state one. Canadian and Ontario requirements are set on their side of the border, so confirm with your insurer, and with the Canadian authorities, that your limits and proof of insurance satisfy them before the first run.

Cargo is the other gap. A load that clears customs, waits at a border facility or sits in a Windsor or Sarnia yard overnight needs a cargo form that covers it there. Ask where your cargo coverage applies and whether it restricts unattended vehicles, because a border delay is exactly when those conditions come into play.

Truck Insurance by Vehicle Type in Michigan

See all vehicle types we cover.

Coverage Beyond the Legal Minimum

In Michigan the broker requirement usually sets your real liability and cargo limits. Brokers and shippers commonly ask for $1,000,000 in auto liability and $100,000 in motor truck cargo before tendering a load, and automotive supply contracts often add their own cargo and delivery terms on top. Read those terms closely: standard cargo coverage responds to physical loss or damage, not to the cost of a late delivery.

If the truck is financed or leased, the lender or lessor requires physical damage coverage for as long as there is a balance, usually with the lienholder named. In Michigan that coverage does extra work. Because the no-fault law limits what you can recover from an insured driver who damages your moving truck to a small mini-tort claim, collision on your own policy is the practical way that damage gets paid, lender or not.

Cross-border and interchange work add a third source. Carriers running into Ontario need to confirm the policy territory, and carriers pulling trailers they do not own under an interchange agreement need trailer interchange coverage sized to the equipment.

See the coverages we offer for how each of these fits together.

Fleet Insurance in Michigan

A second truck and a hired driver turn a Michigan owner-operator into a fleet. Each added power unit needs its own CVED decal and cab card before it runs intrastate, and each Michigan-registered unit carries the no-fault layer, so PIP and property protection scale with the schedule. Driver files, a hiring standard and Clearinghouse obligations come with the employees.

Under MCL 418.115, Michigan's workers' compensation law applies to a private employer that regularly employs three or more people at one time, or fewer than three if at least one has worked 35 or more hours a week for that employer for 13 weeks or longer in the preceding 52. Trucking adds a second trigger: the Motor Carrier Act requires a carrier to demonstrate comp compliance to CVED at initial application, with either proof of coverage or an approved exclusion form from the Workers' Disability Compensation Agency. Comp also interacts with no-fault. Benefits paid under workers' compensation are subtracted from PIP, so for an employee hurt on the job in a company truck, the comp policy responds first.

If you lease on owner-operators, MCL 418.161 treats a person serving your business as an employee for workers' comp unless that person maintains a separate business, holds themselves out to and serves the public, and is an employer subject to the act. When the state's administrative hearing system decides coverage, it applies the IRS 20-factor test, and someone you withhold federal income tax for is presumed to be an employee. Get it wrong and the driver is a comp obligation you did not insure. This is informational; confirm a specific arrangement with the agency or your own attorney.

Your CVED authority and its Form E belong to the carrier, while the decals and cab cards are per vehicle. The annual renewal carries proof of insurance for the whole operation, so a fleet that adds and removes units through the year should keep CVED's equipment list, the policy schedule and the physical decals in step, and surrender decals on units it retires.

Michigan freight supports a short-radius fleet around the Detroit, Grand Rapids and Lansing manufacturing base, with automotive parts, steel and packaged goods moving on tight schedules. Farther north, agriculture, timber and seasonal construction set the pace, with frost laws shaping spring. That mix decides the radius you declare and the equipment you buy.

Running 11 or more units changes the program itself. Deductible structures, loss-sensitive rating and the rest are covered in our guide to fleet insurance for 10 or more trucks.

Switching or Renewing Your Policy in Michigan

MCL 500.3020 applies to casualty policies including all classes of motor vehicle coverage, and it lets an insurer cancel on not less than 10 days' written notice mailed to your last known address. The notice has to tell you not to operate the vehicle, or any other vehicle, unless it is insured as the law requires. Michigan's longer 30-day termination notice in MCL 500.2123 is written for private passenger nonfleet auto policies, so a truck policy written to a business generally falls under the 10-day rule. Check the named insured and the cancellation condition on your own policy.

We did not find a Michigan statute that sets a separate nonrenewal notice period for commercial auto, so the nonrenewal condition in your policy governs. Read it at binding, and start shopping about 60 days before expiration rather than waiting for a notice that may come late.

The filings are where a switch can go wrong. Federally, 49 CFR §387.313 keeps a BMC-91 filing in force until 30 days after the cancellation notice reaches FMCSA. On the Michigan side, CVED grants and renews authority only with proof of insurance on file, and filings are matched to your CVED number. Have the new insurer file its Form E before the old one is cancelled, and do not let a gap open between them.

The Michigan State Police runs a public motor carrier status search on its CVED site. After a switch, check that your authority still shows active and that the new filing has been received, and keep the old policy in place until it has.

Send us your current declarations page, your loss runs and your authority details and we will tell you what your options look like. If you want to understand the process first, read how switching works, step by step or work through our checklist for preparing a renewal.

How to Get Commercial Truck Insurance in Michigan

1. Sort out your authority and know which one you need. Know whether you are applying for FMCSA interstate authority, CVED Authority for Michigan intrastate for-hire work, or both, and have your USDOT number ready if any unit is over 26,001 lbs. CVED will not approve an application without a Form E from your insurer and proof of workers' comp or an exclusion form, so the policy comes before the authority.
2. Confirm your cargo, radius and where you run. Tell the underwriter what you haul, how far, and whether you cross into Ontario or run frost-law routes. Hazmat, heavy haul, automotive just-in-time and cross-border work each change which markets can write you and which limits apply.
3. Choose your coverage, including the no-fault selections. Start from the limit your authority requires, then check it against brokers, contracts and any lienholder. On a Michigan-registered unit, make the PIP medical selection on the signed form deliberately, and decide on UM and UIM, which are optional here. See our coverages page for what each part of the stack does.
4. Compare quotes from multiple carriers. No-fault structure, PIP selections and cross-border exposure price differently from one Michigan market to the next, so a single quote tells you little about what the risk is worth.
5. Bind the policy and get both filings on record. For interstate authority your insurer files the BMC-91 or BMC-91X with FMCSA. For Michigan intrastate authority your insurer files the Form E with CVED, plus a Form H if you move household goods. Both filings come from the insurance company, not from you, and carriers running both need both. New authorities should expect to pay more than an established carrier until there is a clean operating and claims history behind them.
