Michigan Motorcycle Accidents: No-Fault Priority, the Helmet Law, and Your Right to Sue

You were hurt on your motorcycle in Michigan, and the insurance rules don’t match what you’ve heard about car crashes. Here’s the plain answer. Michigan’s no-fault law doesn’t count a motorcycle as a “motor vehicle,” so your motorcycle policy doesn’t include personal injury protection (PIP), the no-fault coverage for medical bills and lost pay. But if a car or truck was involved, you can claim PIP from that vehicle’s insurer first, then down a list set by law. If no motor vehicle was involved, PIP may not be available at all. And you can sue the driver who caused the crash: for pain and suffering if your injury is serious enough under Michigan law, and for losses PIP doesn’t cover.

These rules are current as of September 2026. For how fault is proved and how other states compare, see our national guide to motorcycle accident claims.

Why doesn’t Michigan’s no-fault law treat a motorcycle like a car?

Because the law defines them differently. A “motor vehicle” under the no-fault act is a powered road vehicle with more than two wheels, and the definition expressly leaves out motorcycles (MCL 500.3101(3)(i)). A motorcycle has a seat, no more than three wheels and an engine over 50 cc. Mopeds and off-road vehicles aren’t motorcycles and follow different rules (MCL 500.3101(3)(g)).

Your motorcycle policy won’t pay PIP, but the Michigan Department of Insurance and Financial Services (DIFS), the state’s insurance regulator, says a rider hurt in a crash involving a motor vehicle may still be entitled to it, in most cases from the insurer of that vehicle’s owner.

Who pays your PIP if a car or truck was involved?

If you were on a motorcycle, as operator or passenger, and the crash “shows evidence of the involvement of a motor vehicle,” you claim PIP from these insurers, in this order (MCL 500.3114(5)):

1. The insurer of the car or truck’s owner or registrant
2. The insurer of its driver
3. The auto insurer of the motorcycle’s operator
4. The auto insurer of the motorcycle’s owner or registrant

If none applies, you claim through the Michigan Assigned Claims Plan (MCL 500.3172(1)).

PIP pays reasonably necessary medical care; lost income for up to three years, generally 85% of it and capped for each 30-day period; and up to $20 a day for household help, for three years (MCL 500.3107(1)). The medical limit on the policy that pays applies to you (MCL 500.3107c(5)). See what Michigan PIP pays for coverage levels and the current wage cap.

If your care costs more than the paying policy’s limit, you can claim the rest from an at-fault driver (MCL 500.3135(3)(c)). If PIP is denied or cut off, see what to do when a Michigan PIP claim is denied.

What if the car never touched you?

A car can count as involved without a collision, but being nearby isn’t enough. The Michigan Court of Appeals has held that without a collision, “the operation of the motor vehicle must have created an actual need for the motorcyclist to take evasive action.” It ruled against PIP for a rider who braked at approaching headlights and crashed, because nothing showed he needed to (Detroit Medical Center v Progressive Michigan Insurance Co, 302 Mich App 392 (2013)).

The same court applied that rule in Stuth v Home-Owners Insurance Co. A van veered onto the double yellow line as the rider rounded a curve, and he steered off the road and was hurt. The van never entered his lane, didn’t stop, and no one else saw it. The trial judge believed him and ruled that he was entitled to PIP. The Court of Appeals accepted that the van was there but reversed: he had agreed there would have been no accident if he had stayed on his path, so the van hadn’t created an actual, objective need to take evasive action. In January 2024 the Michigan Supreme Court declined to review the case, over two justices’ dissent.

So if a car ran you off the road, write down everything about it, look for witnesses and video, and ask a lawyer whether it counts. A crash into a parked car counts only in narrow cases, such as a car parked in a way that caused an unreasonable risk of the injury (MCL 500.3106(1)(a)).

Who can’t get PIP at all?

These riders can’t get PIP from any insurer or the Assigned Claims Plan (MCL 500.3113, 500.3173):

• The owner or registrant of an uninsured motorcycle involved in the crash (MCL 500.3103(1), 500.3113(b)). Using someone else’s bike for more than 30 consecutive days can make you an owner; borrowing one with permission for less than 30 consecutive days doesn’t (MCL 500.3101(3)(l)(ii)).
• Someone willingly riding a bike they knew or should have known was taken unlawfully (MCL 500.3113(a)).
• An operator the motorcycle’s policy named as excluded (MCL 500.3113(d)).
• A nonresident, unless they own a motor vehicle registered and insured in Michigan (MCL 500.3113(c)).

What if no car or truck was involved?

Think of a slide on gravel, a pothole, a deer, or a crash with another motorcycle. PIP pays for injuries arising from the use of a motor vehicle (MCL 500.3105(1)), and DIFS says that when a motorcycle crash doesn’t involve one, PIP may not be available. The Assigned Claims Plan has the same motor vehicle requirement (MCL 500.3172(1)).

What pays instead:

• Your health insurance.
• Your motorcycle policy’s medical coverage, if you bought it. The law designs it for a “motorcycle accident,” one with no motor vehicle involved, and it covers the policyholder, their spouse and relatives who live with them (MCL 500.3101(3)(h), 500.3114(1)). Each insurer sets its own maximum (DIFS).
• A claim against whoever caused the crash, such as a road agency that didn’t fix a dangerous defect (see the deadlines below) or another rider. Ask a lawyer how that claim works.

What does the Assigned Claims Plan cover, and what are its limits?

The Michigan Assigned Claims Plan is the safety net for people hurt in a Michigan crash involving a motor vehicle. You apply to the Michigan Automobile Insurance Placement Facility, which assigns your claim to an insurer (MCL 500.3172(3), 500.3174). You can use it if no PIP insurance applies or can be identified (as after some hit-and-run crashes), if insurers dispute who pays, or if the insurer that owes you can’t pay because of financial trouble (MCL 500.3172(1)). In a dispute, the plan assigns an insurer to start paying while a court sorts it out (MCL 500.3172(6)).

Its limits:

• Medical care is capped at $250,000 in most cases (MCL 500.3172(7)).
• Other coverage comes first. Unless the plan is paying because insurers dispute who owes you, benefits are reduced by other coverage for the same loss, such as health insurance, but not Medicare or Medicaid (MCL 500.3172(5)).
• One year to notify. Notify the plan within one year of the crash (MCL 500.3174), and file its claim form with reasonable proof of your loss (MCL 500.3172(3)).

Do you have to wear a helmet in Michigan?

Yes, unless you’re 21 or older and meet the conditions. Every operator and passenger must wear a crash helmet approved by the Michigan State Police, with these exceptions (MCL 257.658(4)-(6)):

That $20,000 is the optional motorcycle medical coverage described above (MCL 257.658(5)(c), 500.3103).

In 2024, 184 motorcyclists died in Michigan crashes. Of the 170 whose helmet use was known, 77 (45%) weren’t wearing one, compared with 34% nationwide, according to the National Highway Traffic Safety Administration (NHTSA), whose counts include moped and scooter riders.

Does riding without a helmet hurt your claim?

Not your PIP. PIP is paid without regard to fault (MCL 500.3105(2)), and riding without a helmet isn’t among the reasons the law lists for denying it (MCL 500.3113).

Your claim against the driver is less certain. The helmet law doesn’t say how riding without one affects an injury claim, and it has nothing like the seat-belt law’s 5% cap on reduced recovery (MCL 257.710e(8)). The other side may argue that a helmet would have prevented or reduced a head injury, to cut your damages. Don’t assume your claim is over, or that it’s unaffected. Ask a lawyer how it could affect yours.

Can you sue the driver who caused the crash?

Yes. The no-fault law limits lawsuits against drivers, but it keeps these claims open (MCL 500.3135).

Pain and suffering, if your injury meets the threshold

You can recover noneconomic damages (pain, suffering and other harm that doesn’t come with a bill) only if the crash caused death, serious impairment of body function or permanent serious disfigurement (MCL 500.3135(1)). This is called the threshold. A serious impairment must (MCL 500.3135(5)):

1. be objectively manifested, meaning someone other than you can observe or perceive it from actual symptoms or conditions,
2. affect an important body function, one of great value, significance or consequence to you, and
3. affect your general ability to lead your normal life, meaning it has had an influence on some of your capacity to live the way you normally did.

It doesn’t have to be permanent. The statute sets no minimum time, and each case compares your life before and after the crash (MCL 500.3135(5)(c)). See how the serious impairment threshold works.

Money losses above PIP

You can also claim medical costs above the PIP limit that applied to you, and lost income beyond PIP’s monthly cap or its three years (MCL 500.3135(3)(c)). Michigan residents don’t need to meet the threshold for this; nonresidents do (MCL 500.3135(3)(d)). If the policy that paid your PIP had a $250,000 medical limit and your care costs $400,000, you can claim the other $150,000 from the at-fault driver.

The driver’s liability insurance usually pays. For policies issued or renewed after July 1, 2020, that’s at least $250,000 per person and $500,000 per crash, unless the policyholder signed a form choosing lower limits, as low as $50,000 and $100,000 (MCL 500.3009(1), (5)). See how PIP and a lawsuit fit together.

How your share of fault counts

Michigan gives a motorcycle the full use of a lane (MCL 257.660(2)) but bars riders from passing between lines of traffic (MCL 257.660(5)), so lane splitting can be used to argue that you share the blame. And if alcohol or a controlled substance impaired your ability to function and, as a result, you were 50% or more the cause of the crash, you can’t recover at all (MCL 600.2955a(1)). See how comparative fault works in Michigan.

What about damage to your motorcycle?

PIP pays for bodily injury, not your bike (MCL 500.3105(1)).

• Collision coverage on your motorcycle policy pays, if you bought it (DIFS).
• A parked bike hit by a car may be covered by the no-fault property protection insurance of the vehicles involved, which excludes vehicles unless they were parked in a way that didn’t cause an unreasonable risk of the damage. A lawsuit for those benefits is due within one year (MCL 500.3121(1), 500.3123(1)(a), 500.3125, 500.3145(5)).
• The $3,000 “mini-tort” that car owners use for uncovered damage applies to damage “to a motor vehicle” (MCL 500.3135(3)(e)), a term that excludes motorcycles (MCL 500.3101(3)(i)). The statute doesn’t spell out what that means for your bike, so ask a lawyer what you can recover for it and your gear.

What if the driver had no insurance, or not enough?

Your PIP doesn’t depend on the other driver’s insurance; you just move down the priority list. But pain and suffering and losses above PIP come from the at-fault driver, who may have too little insurance or none.

That’s what uninsured (UM) and underinsured (UIM) motorist coverage is for, and in Michigan it’s optional. The law requires only liability insurance on a motorcycle (MCL 500.3103(1)), and the Michigan Supreme Court has called uninsured motorist coverage “optional,” with rights and limits that are “purely contractual” (Rory v Continental Insurance Co, 473 Mich 457 (2005)). Check your motorcycle policy and any car policy, and read the deadline. In Rory, the policy required a claim or suit within one year of the accident. The injured people learned the other driver was uninsured only after suing her, more than a year after the crash, and the Court enforced the one-year limit.

What are the deadlines after a Michigan motorcycle crash?

Road agencies must keep the part of the road built for vehicle travel in reasonable repair (MCL 691.1402(1)). The notice must give the exact location and nature of the defect, your injury and known witnesses (MCL 691.1404(1)). For state and county roads and children, see every Michigan injury deadline in one place.

What to do next

1. Get medical care, and keep every record. Tell providers about every symptom, including any blow to the head, and what you can no longer do.
2. Identify every insurer. Get the car’s owner, driver and insurance details from the crash report, plus your own car and motorcycle policies.
3. Send written notice now to the insurer first in line, and to the others if you’re unsure which one owes you (MCL 500.3145(1)). If no policy applies, notify the Assigned Claims Plan (MCL 500.3174).
4. Preserve evidence: your helmet, gear and bike, plus photos, witness names and video, especially if a car ran you off the road without touching you.
5. Get a free case review before you give the other driver’s insurer a recorded statement or sign a release, or compare Michigan motorcycle accident lawyers. Get the fee in writing; see how injury lawyers get paid.

What waiting can cost

• Your PIP benefits. Without written notice or a payment within one year, you can lose the right to sue for them (MCL 500.3145(1)).
• A road-defect claim. Notice to the agency is due within 120 days.
• Proof that a car was involved. Witnesses move on and video gets recorded over.
• Your UM/UIM claim and your lawsuit. Your policy may set its own deadline (Rory enforced one year), and a lawsuit against the driver is generally too late after three years.

What a good outcome looks like

The right insurer pays your medical bills and wage-loss benefits while you heal. Fault is decided on the evidence, not on assumptions about riders. If your injury meets the threshold, the at-fault driver’s insurer pays for your pain and suffering and the losses PIP doesn’t reach, and your underinsured motorist coverage, if you have it, helps when theirs runs out. You make each decision knowing your coverage, your deadlines and your lawyer’s fee. From wondering which insurance covers a rider after a Michigan crash to knowing whether PIP applies, who pays it and when you can sue the other driver.
