Michigan Seat Belt Law: Who Must Buckle Up, Car Seat Rules and Your Injury Claim

You were hurt in a Michigan crash, and now an insurance adjuster wants to know whether you were wearing a seat belt. If you weren’t, and you’re afraid that ends your claim, that’s a normal worry. Here is the plain answer.

Michigan requires every driver and front-seat passenger to buckle up, and every child under 16 to be belted or in the right car seat, wherever they sit (MCL 257.710d, 257.710e). Police can stop you for a seat belt violation alone, and the ticket costs $65 with no points. Where the law required a belt, not wearing one can reduce what you recover from the at-fault driver by no more than 5%, so it doesn’t end your claim. It doesn’t reduce your no-fault personal injury protection (PIP) benefits at all (MCL 257.710e(8), 500.3105(2)).

What is the seat belt law in Michigan?

Every driver and every front-seat passenger must wear a “properly adjusted and fastened safety belt.” Children under 16 must be buckled up or in the right car seat in every seat, and the driver is responsible for them (MCL 257.710e(3), (5); 257.710d(1)).

The State of Michigan’s seat belt law is MCL 257.710e; its car seat law is MCL 257.710d:

The Michigan State Police’s Office of Highway Safety Planning (OHSP) says a shoulder belt worn behind your back or under your arm doesn’t comply and carries the same penalty as no belt. Teen drivers are responsible for passengers under 16, too; see what teen drivers should do after a crash.

Do back-seat passengers have to wear a seat belt in Michigan?

Only passengers under 16. The law requires belts for the driver and front-seat passengers and for children in every seat, but not for passengers 16 and older in the back (MCL 257.710e(3), (5)). It’s still the safer choice: OHSP calls buckling up “the single most effective thing you can do to protect yourself in a crash.”

Is Michigan a primary seat belt state?

Yes. According to OHSP, police can stop a vehicle and write a ticket just because the driver, a front-seat passenger or a passenger under 16 isn’t buckled up.

Under secondary enforcement, police could ticket a belt violation only after stopping a driver for something else. Michigan’s law has been primary since 2000, and it would switch to secondary only if OHSP certified that compliance fell below 80% in the previous year (MCL 257.710e(7)). A 2025 Michigan State University survey for OHSP measured front-seat belt use at 93.2%. The car seat law has no secondary-enforcement rule (MCL 257.710d).

What are Michigan’s car seat and booster seat laws?

A child must ride in a rear-facing car seat until age 2 and a forward-facing harnessed seat until age 5, moving up sooner only by outgrowing the seat, and then in a booster seat until age 8 or 4 feet 9 inches. Children under 13 must ride in the back seat if the vehicle has one (MCL 257.710d).

These rules took effect April 2, 2025, under 2024 Public Act 21 (Michigan State Police Legal Update No. 162). Each stage ends at the age or size limit, whichever comes first:

Each seat must fit the child and be set up as the seat maker and vehicle maker instruct (MCL 257.710d(3)). The law sets a minimum. “To maximize safety,” the Legislature recommends keeping a child in a car seat or booster as long as it fits (MCL 257.710d(4)).

When can a child ride in the front seat in Michigan?

At 13. A younger child may ride in front only if the vehicle has no back seat or every back seat is taken by other children, and a rear-facing seat may go in front only if the front passenger air bag is turned off (MCL 257.710d(2), (4)).

Can you use a car seat again after a crash?

Not after a moderate or severe crash: the National Highway Traffic Safety Administration (NHTSA) recommends replacing the seat. After a minor crash, which NHTSA defines as one where the vehicle could be driven away, the door nearest the seat wasn’t damaged, no passengers were hurt, no air bags deployed and the seat shows no visible damage, it doesn’t automatically need replacing. NHTSA also says to always follow the seat maker’s instructions.

How much is a seat belt ticket in Michigan?

$65, as of September 2026: a $25 fine and court costs set by statute, plus a $40 justice system assessment, as OHSP explains (MCL 257.907(2)(o), (12)).

It’s a civil infraction, not a crime, with no points, and it isn’t entered on your driving record (MCL 257.6a, 257.710e(9), (13); 257.732(16)(e)). A car seat or booster violation is a separate civil infraction for the driver, with no points and no report to the Secretary of State (MCL 257.710d(7), (8)). The fine is up to $10 plus court costs, and the $40 assessment applies unless the fine and costs total $10 or less (MCL 257.907(2)(n), (12)). The court can waive the fine, costs and assessment if, before the appearance date, you show you’ve gotten a proper seat and received education from a certified child passenger safety technician (MCL 257.907(11)).

Who is exempt from Michigan’s seat belt law?

Only the vehicles and people the statute lists, such as buses, motorcycles and pre-1965 cars. A medical exemption requires a physician’s written verification that you can’t wear a belt for physical or medical reasons; keep it with you (MCL 257.710e(1)).

The belt law doesn’t apply to the driver or passengers of:

• a vehicle made before January 1, 1965
• a bus, a motorcycle or a moped (for helmet rules, see Michigan motorcycle accident law)
• a vehicle that federal law doesn’t require to have seat belts
• a commercial or U.S. Postal Service vehicle that makes frequent stops to pick up or deliver goods or services
• a vehicle driven by a Postal Service rural carrier on a rural route

It also doesn’t apply to school bus passengers. A driver complies when there are more passengers than belts and every belt is in use as the law requires, and a driver doing road work in a work zone needs only the lap belt (MCL 257.710e(2), (4), (6)).

The car seat law doesn’t apply in buses, school buses, taxicabs, on mopeds or motorcycles, or in other vehicles federal law doesn’t require to have belts. The Secretary of State can also exempt groups of children by rule when a car seat is impractical because of physical unfitness, a medical problem or body size (MCL 257.710d(6), (9)).

Does not wearing a seat belt affect an injury claim in Michigan?

If the law required a belt, not wearing one can reduce what you recover from the at-fault driver, but by no more than 5%. It doesn’t reduce your PIP benefits, which are due without regard to fault (MCL 257.710e(8), 500.3105(2)).

The rule, word for word:

“Failure to wear a safety belt in violation of this section may be considered evidence of negligence and may reduce the recovery for damages arising out of the ownership, maintenance, or operation of a motor vehicle. However, that negligence must not reduce the recovery for damages by more than 5%.” (MCL 257.710e(8))

The word “may” appears twice: the seat belt is evidence to weigh, not an automatic deduction. And the side claiming you were at fault has to prove it (MCL 600.2960(1)).

How much can a missing seat belt cost you?

No more than 5%: on a $100,000 recovery, $5,000 at most. Whether you can claim pain and suffering at all still depends on your injury (MCL 500.3135(1)), as our guide to Michigan’s serious impairment threshold explains.

How does it fit with Michigan’s comparative fault rules?

Michigan reduces your damages by your percentage of fault (MCL 600.2959), and in a crash lawsuit for pain and suffering, no damages go to a party more than 50% at fault (MCL 500.3135(2)(b)). A seat belt doesn’t cause a crash, so the other side may argue instead that a belt would have prevented or reduced your injuries. Any fault for the crash itself reduces your damages too, but the seat belt part alone can’t take more than 5%. See how comparative fault works in Michigan.

Does a missing seat belt reduce your PIP benefits?

No. PIP benefits for medical care, lost income and help at home are due “without regard to fault” (MCL 500.3105(2), 500.3107(1)). The seat belt rule reduces a “recovery for damages,” such as your claim against the at-fault driver. See what Michigan no-fault benefits pay.

What if you were in the back seat, or your child was hurt?

The 5% rule covers failing to wear a belt “in violation of this section,” but Michigan doesn’t require adults in the back seat to buckle up, and the car seat law has no matching 5% rule. If either fits you, don’t assume the answer either way; ask a lawyer how the seat belt could come up in your claim.

What if the insurer says you weren’t buckled?

The other driver’s insurer handles claims like yours every day, and it may raise the seat belt to justify a lower offer. That’s its position, not a finding. Evidence decides it:

• The crash report. Michigan’s UD-10 crash report records each person’s restraint use, based on the officer’s investigation, and only the police agency that wrote it can change it (Michigan State Police). Our guide to Michigan car accident claims explains how to get a copy.
• The event data recorder. If the vehicle has one and was built on or after September 1, 2012, federal rules generally require it to record whether the driver was buckled just before the crash (49 CFR 563.3, 563.7).
• Your own words. Answer seat belt questions truthfully. If you don’t remember, say so rather than guess.

What to do next

1. Get medical care, and keep every record. See a doctor soon and describe every symptom, belted or not.
2. Give your auto insurer written notice within one year. Unless it has already paid PIP benefits, you can lose the right to sue for them without written notice of your injury within a year of the crash (MCL 500.3145(1)).
3. Check the crash report’s restraint entries. If one is wrong, contact the police agency that wrote the report, with photos or other proof.
4. Replace your child’s car seat after anything but a minor crash, using NHTSA’s test above. Photograph the old seat first, and if your child was hurt, keep it.
5. Get a free case review before you accept a seat belt cut. If an insurer wants more than 5%, or you aren’t sure the law required a belt, get a free case review or compare Michigan injury lawyers, and get any fee agreement in writing.

What waiting can cost

• Your PIP benefits. Without written notice or a payment within a year of the crash, you can lose the right to sue for PIP benefits (MCL 500.3145(1)).
• Your lawsuit. Most injury lawsuits must be filed within three years of the injury (MCL 600.5805(2)). See every Michigan injury deadline in one place.
• Proof that you were buckled. Damaged cars get repaired or scrapped, and the event data recorder goes with them.

What a good outcome looks like

Your PIP insurer pays your medical bills and wage benefits on time, belt or no belt. Any seat belt reduction rests on evidence and stays within the 5% the law allows. From worrying that a seat belt ruined your claim to knowing exactly how much it can matter, and how little.
