Check your child's stage in Maryland
Enter age, height, and weight. We show the Maryland law separately from best practice.
4′9″ = 57 in. Enter only the boxes you have; this state uses child safety seat required while under 8 AND shorter than 4′9″; reaching age 8 or 4′9″ exits.

The four stages in Maryland
Each rung is tagged Law or best practice.
A child younger than 2 must ride in a rear-facing child safety seat until they reach the seat manufacturer’s weight or height limit. This became law under SB 176, effective October 1, 2022. A first rear-facing violation draws a written warning rather than a fine.
After rear-facing, Maryland requires a child under 8 to be in a child safety seat per the manufacturer’s instructions but does not set a separate forward-facing harness age.
AAP/NHTSA best practice: use a forward-facing harness seat after rear-facing, then a booster. That is a recommendation, not a Maryland statutory stage.
A child under 8 must be secured in a child safety seat (a booster counts) per the manufacturer’s instructions, unless the child is 4′9″ or taller. Reaching age 8 or 4′9″ ends the requirement.
Exit rule: child safety seat required while under 8 AND shorter than 4′9″; reaching age 8 or 4′9″ exits. The adult belt must fit — lap low across the hips, shoulder belt across the chest.
Front seat, the fine & the source
Seating rule, the exact booster logic, and any recent change.
Maryland §22-412.2 has no front-seat-only age rule. Back-seat placement for young children is best practice, not Maryland law.
| Booster exit logic | Age 8 or 4′9″ — whichever first |
| Seat belt OK | Age 8, or once the child is 4′9″ or taller |
| First-offense fine | $50 $50 per violation. A judge may waive the fine if the person did not own a seat at the time, buys one before the hearing, and shows proof to the court. |
| Statute | Md. Transp. §22-412.2 |
Maryland added the rear-facing-under-2 requirement through SB 176, effective October 1, 2022. A first violation of that specific rear-facing rule is a written warning, not a fine. Summaries predating October 2022 do not include the rear-facing mandate.
What Maryland parents get wrong
Maryland keeps its main rule simple: a child under 8 must ride in a child safety seat, which includes a booster, unless the child is already 4′9″ or taller. So the booster exit is age or height: reaching 8 or 4′9″ ends the requirement. As of October 1, 2022, Maryland also codified rear-facing for children under 2 through SB 176, so rear-facing is law here rather than only a recommendation, though a first rear-facing violation brings a written warning instead of a fine. Maryland does not set a separate forward-facing harness age, and it has no front-seat age ban. The standard fine is $50, and a judge may waive it if the driver did not own a seat but buys one before the court date.
Common questions
When can a child stop using a booster in Maryland?
At age 8, or once the child is 4′9″ (57 in) or taller. Maryland requires a child safety seat, booster included, while a child is under 8 and shorter than 4′9″.
Does Maryland require rear-facing car seats by age?
Yes, since October 1, 2022 (SB 176). A child under 2 must ride rear-facing until they reach the seat’s weight or height limit. A first violation of this rear-facing rule is a written warning.
Do children have to ride in the back seat in Maryland?
Not by law. Maryland §22-412.2 has no front-seat age rule. Back-seat placement for young children is a recommendation, not a statute.
What is the fine for a car-seat violation in Maryland?
$50 per violation. A judge may waive it if the person did not own a seat at the time, buys one before the hearing, and shows proof to the court.
