Michigan Seat Belt Law: Fines, Exemptions, and Child Rules

Michigan’s seat belt law requires every driver and front-seat passenger to wear a properly fastened seat belt on any public road, and it requires children under 16 to be restrained no matter where they sit. Police can pull you over for a belt violation on its own. The ticket is a civil infraction of roughly $65 with no points, but being unbuckled can also cut into an injury settlement if you’re hurt in a crash.

Who Has to Buckle Up

Under MCL 257.710e, the driver and every front-seat passenger must wear a properly adjusted and fastened seat belt whenever the vehicle is on a Michigan street or highway.¹

Children under 13 fall under a separate, stricter child restraint statute, MCL 257.710d. Passengers aged 13 through 15 come back under the general belt law and must buckle up whether they sit in front or in back.²

Here is the gap that surprises most people: adults 16 and older riding in the rear seat are not required by Michigan law to wear a belt. Safety groups recommend belting up in every seat, but there is no ticket for an unbuckled adult in back.¹

Child Restraint Rules

Michigan updated its child passenger safety law effective April 2, 2025, adding a mandatory rear-facing stage and tightening the move from car seat to booster to belt. The driver is the one on the hook. If a child in the vehicle isn’t properly restrained, the driver gets the ticket.³

The stages work by age and size:

Rear-facing car seat until the child turns 2 or exceeds the seat manufacturer’s height or weight limit, whichever comes first.
Forward-facing car seat with a harness after the child outgrows the rear-facing seat, until age 5 or the manufacturer’s limits.
Booster seat after the child outgrows the forward-facing harness, until the child reaches 4 feet 9 inches or turns 8.
A regular seat belt after the booster stage, with the child in the rear seat when one is available, until age 13.

⁴

At every stage the restraint has to match the child’s current weight and height, and it must be installed according to both the car seat maker’s and the vehicle maker’s instructions.²

Front-Seat and Airbag Rule for Children Under 4

Children under 4 must ride in a car seat in the back. If the vehicle has no rear seat, or every rear seat is already taken by another child under 4, the child may ride up front. A child in a rear-facing car seat can only ride in front if the passenger-side airbag is turned off, because a deploying airbag can seriously injure a small child in a rear-facing seat.⁴

Enforcement and the Fine

Michigan enforces its seat belt law as a primary offense. An officer can stop you solely because someone in the vehicle appears unbuckled, with no other reason needed.⁵

A belt violation is a civil infraction, not a crime. The fine runs about $65, though court costs can raise the total depending on the court. No points go on your driving record, and the violation does not appear on the abstract sent to the Secretary of State.¹ The same treatment applies to a child restraint violation under MCL 257.710d: civil infraction, no points.²

Exemptions

The statute carves out specific situations where the belt requirement does not apply:¹

Vehicles manufactured before January 1, 1965, which predate federal belt requirements and typically have no belt hardware.
A person with a physical or medical condition that makes belt use unsafe, if they carry a written physician’s statement explaining the condition. Keep the letter in the vehicle so you can show it if you’re stopped.
Passengers on buses, including school buses.
Motorcycles and mopeds, which have their own laws.
Drivers and passengers in commercial or U.S. Postal Service vehicles while making frequent delivery stops, and rural mail carriers on their routes.
Any motor vehicle federal law does not require to be equipped with seat belts.

How a Belt Violation Affects an Injury Claim

The bigger financial consequence of skipping the belt usually isn’t the ticket. It’s what happens if you get hurt. Michigan law lets the other driver’s insurer argue that failing to wear a belt made your injuries worse, treating that failure as evidence of negligence that can reduce your recovery in a lawsuit.¹

The statute caps that reduction at 5% of your total damages. On a $200,000 verdict, the most the defense can shave off for the unbuckled belt is $10,000. The defense still has to prove that wearing a belt would have actually prevented or reduced your specific injuries. A citation by itself isn’t a blanket reduction.¹

The 5% cap covers third-party injury claims only. It does not reduce your first-party no-fault benefits, so PIP medical coverage, wage loss, and replacement services are not affected by whether you were belted. The cap also does not apply to product liability cases against vehicle manufacturers, where courts have let the belt defense be weighed as ordinary comparative fault with no statutory ceiling.

Riding in a Pickup Truck Bed

Michigan restricts who can ride in the open bed of a pickup on public roads. Anyone under 18 is generally prohibited from riding in the cargo area, with one everyday exception: a passenger under 18 may ride in the bed if the vehicle is moving at 15 miles per hour or less.⁶

Additional exceptions cover parades, farming operations, construction work, military vehicles, and emergencies. Adults 18 and older may legally ride in a pickup bed at any speed.⁷

Responding to a Seat Belt Ticket

Your citation states a deadline to respond. You have three options:

Admit responsibility and pay the fine by the deadline. The infraction is resolved, though it may still be visible to your insurer.
Admit with explanation and request an informal hearing before a magistrate. You can explain the circumstances, and the magistrate may reduce the fine, though the infraction still stands.
Deny responsibility and request a formal hearing. You and the citing officer both present your side, and a judge or magistrate decides whether the violation occurred.

Ignore the ticket and the court enters a default judgment. Michigan no longer suspends licenses solely for unpaid civil infraction fines, a change that took effect in 2021, but a default still brings added fees and possible collection actions.
