Maryland car seat laws require every child under 16 to be restrained whenever they ride in a vehicle, with the type of restraint set by age and height: rear-facing under 2, a child safety seat from 2 through 7 unless the child is already 4 feet 9 inches tall, and a seat belt (at minimum) from 8 through 15.1Maryland General Assembly. Maryland Transportation Code 22-412.2 It’s a primary offense, so an officer can pull you over for the violation alone.
Rear-Facing Until Age 2
Every child under 2 has to ride in a rear-facing car seat that meets federal safety standards and is used according to the manufacturer’s instructions.1Maryland General Assembly. Maryland Transportation Code 22-412.2 The manufacturer’s limits matter: a child who turns 2 but still fits within the seat’s rear-facing weight and height limits can stay rear-facing, and many seats accommodate children well past their second birthday.
Once the child turns 2 or outgrows the rear-facing limits of the seat, they move into the next category.
Child Safety Seats From Ages 2 Through 7
Children between 2 and 7 must ride in an appropriate child safety seat unless they have already reached 4 feet 9 inches in height.1Maryland General Assembly. Maryland Transportation Code 22-412.2 Under Maryland law, “child safety seat” covers forward-facing harnessed seats, belt-positioning boosters, and other federally approved child restraint devices.2Maryland Department of Health. Kids In Safety Seats – Maryland Child Passenger Safety Law A regular seat belt alone does not satisfy the law for this age group.
The move from a harnessed forward-facing seat to a booster depends on the manufacturer’s weight and height limits for your particular seat, not on a specific birthday. Most children transition when they outgrow the harness, which is typically somewhere between 40 and 65 pounds.
The seat has to be installed according to both the car seat manufacturer’s instructions and the vehicle manufacturer’s instructions.1Maryland General Assembly. Maryland Transportation Code 22-412.2 If your vehicle’s manual says a particular seating position isn’t compatible with a car seat, installing one there can put you out of compliance even though a seat is physically present.
The 4-Foot-9-Inch Height Exception
A child who has reached 4 feet 9 inches can legally ride in a standard seat belt regardless of age.1Maryland General Assembly. Maryland Transportation Code 22-412.2 A tall 6-year-old who clears that mark can use just a seat belt; a smaller 7-year-old who hasn’t still needs a booster.
Seat Belts From Ages 8 Through 15
Restraint requirements don’t end at 8. Children from 8 through 15 must be secured in either a child safety seat or a seat belt every time they ride.1Maryland General Assembly. Maryland Transportation Code 22-412.2 For most kids this age that means a seat belt, but if an older child is small enough that the belt doesn’t fit correctly, a booster remains legal. Maryland sets no upper age limit on booster use.
Front Seat and Airbag Rule
Maryland doesn’t broadly ban children from the front seat, but there is one hard prohibition: you cannot place a rear-facing car seat in the front passenger position if the airbag is active.2Maryland Department of Health. Kids In Safety Seats – Maryland Child Passenger Safety Law If your vehicle has no way to deactivate the passenger airbag and no back seat, you cannot legally install a rear-facing seat up front.
Medical Exemptions
If a physician licensed in the state where your vehicle is registered certifies in writing that a child safety seat is impractical because of the child’s weight, height, physical condition, or another medical reason, you won’t be found in violation.1Maryland General Assembly. Maryland Transportation Code 22-412.2 Keep the written certification in the vehicle. Without it, an officer has no way to verify the exemption during a stop.
Fines, Warnings, and the Fine Waiver
A child restraint violation is a primary offense, so an officer can stop you based on it alone. The driver receives the citation, whether or not the child’s parent is in the car.
The standard fine is $50.1Maryland General Assembly. Maryland Transportation Code 22-412.2 There’s one exception: if your child is under 2 and is in a car seat that isn’t rear-facing, the first offense results in a written warning rather than a fine. Later violations carry the standard $50 penalty.
A judge can waive the fine entirely if three things are true: you didn’t have a car seat at the time of the stop, you bought one before your court date, and you bring proof of purchase to court.1Maryland General Assembly. Maryland Transportation Code 22-412.2
One other protection worth knowing: a child restraint violation cannot be used as evidence of negligence in a civil lawsuit. If you’re in a crash and your child’s seat wasn’t fully compliant, the other side cannot point to the violation to argue fault.1Maryland General Assembly. Maryland Transportation Code 22-412.2
Replacing a Car Seat After a Crash
NHTSA says a car seat does not need replacement after a minor crash, but all five of these conditions must be true for the crash to qualify as minor:3NHTSA. Car Seat Use After a Crash
- You were able to drive the vehicle away from the scene.
- The door nearest the car seat was undamaged.
- Nobody in the vehicle was injured.
- None of the airbags deployed.
- The car seat itself shows no visible damage.
If any one of those isn’t true, replace the seat. Many auto insurance policies cover the replacement, so check with your insurer first.
Free Car Seat Inspections
Maryland’s Kids In Safety Seats program, run through the Department of Health, offers free car seat checks where a certified technician verifies that your seat is installed correctly and matched to your child’s size.4Maryland Department of Health. Kids in Safety Seats – KISS Inspection events rotate around the state, and the program also offers video appointments over Zoom if you can’t make it in person.
