Maryland Car Seat Laws: Requirements and Guidelines
Overview of Maryland Car Seat Laws
Maryland's child passenger safety law is found in Transportation Article Section 22-412.2 of the Maryland Code. The law requires all children under the age of 8 to be secured in a child safety seat that meets federal safety standards, unless the child is at least 4 feet 9 inches tall. Children ages 8 through 15 must wear a seat belt in every seating position.
Maryland updated its child passenger safety law effective October 1, 2022, adding a specific rear-facing requirement for children under 2. The state also operates the KISS (Kids in Safety Seats) program through the Maryland Department of Health to educate parents and caregivers about proper car seat use.
Rear-Facing Car Seat Requirements in Maryland
Under Maryland law, children under the age of 2 must ride in a rear-facing child safety seat until they reach the weight or height limit set by the car seat manufacturer. This requirement took effect on October 1, 2022, as part of updates to Section 22-412.2.
Why Rear-Facing Is Safest
Rear-facing seats protect a young child's head, neck, and spinal cord during a collision. The seat distributes crash forces across the child's entire back rather than concentrating them on the neck and head. According to NHTSA, rear-facing seats reduce fatal crash injuries by 71% for infants under 1 year old.
Types of Rear-Facing Seats
Maryland parents can choose from two main types:
- Infant-only seats support babies from approximately 4 to 35 pounds. These seats often come with a detachable base and carry handle.
- Convertible seats work rear-facing and forward-facing. Many support rear-facing use up to 40 or 50 pounds, allowing children to stay rear-facing well past age 2.
The KISS program recommends placing rear-facing seats in the back seat of the vehicle and never in front of an active airbag. Always follow the manufacturer's instructions for harness adjustments and recline angle.
Forward-Facing Car Seat Requirements in Maryland
Once a child outgrows the rear-facing seat's height or weight limit, the child transitions to a forward-facing car seat with a five-point harness. The KISS program recommends children use forward-facing seats from approximately 20 to 65 pounds, depending on the specific seat.
Proper Use of Forward-Facing Seats
Forward-facing seats should be installed in the back seat using the LATCH system or the vehicle's seat belt, plus the top tether strap. The harness straps should sit at or above the child's shoulders. The chest clip should rest at armpit level, and the harness should be tight enough that you cannot pinch excess webbing at the shoulder.
Children should remain in a forward-facing harness seat as long as possible before transitioning to a booster. Many forward-facing seats support children up to 65 pounds, which means some children can use them until age 6 or 7.
Booster Seat Requirements in Maryland
Maryland law requires children under 8 who have outgrown their forward-facing harness seat and are shorter than 4 feet 9 inches to ride in a federally approved booster seat. A booster seat lifts the child so the vehicle's lap and shoulder belt fits properly across the body.
Proper Booster Seat Fit
For a correct fit in a booster seat:
- The lap belt should sit low across the upper thighs, not across the stomach
- The shoulder belt should cross the center of the chest and rest on the shoulder, not the neck
- The child should sit with their back flat against the vehicle seat back
Types of Booster Seats
| Booster Type | Best For | Head Support |
|---|---|---|
| High-back booster | Vehicles without adjustable rear headrests | Built-in head and neck support |
| Backless booster | Vehicles with adjustable headrests in the rear | Relies on vehicle headrest |
The KISS program advises against using booster seats with lap-only seat belts. A lap-shoulder combination belt is required for a booster to work correctly. Most booster seats support children up to 100 or 120 pounds, so the primary factor for transitioning out of a booster is height rather than weight.
Seat Belt Requirements for Children in Maryland
Children ages 8 through 15 must wear a seat belt in every seating position in the vehicle. A seat belt fits properly when:
- The lap portion sits low and snug across the upper thighs
- The shoulder portion crosses the chest and rests on the shoulder
- The child can sit all the way back against the seat with knees bent at the seat edge
If the seat belt does not fit correctly, the child should continue using a booster seat even after turning 8. The Maryland Department of Transportation recommends keeping children in the back seat until at least age 13.

Penalties for Car Seat Violations in Maryland
Violating Maryland's child safety seat law under Section 22-412.2 carries the following consequences:
- Standard fine: $50 for a violation
- Rear-facing violation (first offense): A written warning for a first-time violation involving a child under 2 not in a rear-facing seat
- Fine waiver: A judge may waive the fine if the driver did not own a car seat at the time of the violation, acquires one before the hearing, and provides proof to the court
- Multiple children: Failure to provide proper restraints for more than one child in the same vehicle at the same time counts as a single violation
Car seat violations in Maryland are civil citations. They do not add points to a driver's license and do not appear on a criminal record.
Exemptions to Maryland Car Seat Laws
Maryland's car seat law includes several exemptions:
- Taxis and for-hire vehicles: Taxis are exempt from child car seat requirements. However, parents should still bring a car seat when using any vehicle with their child.
- Vehicle types: The law applies to Class A (passenger), Class E (truck), and Class M (multipurpose) vehicles registered or capable of being registered in Maryland. It does not apply to buses.
- Medical exemptions: Children with medical conditions that prevent use of standard restraints may qualify for an exemption with a physician's written statement.
The KISS Program in Maryland
Maryland's Kids in Safety Seats (KISS) program is one of the oldest child passenger safety programs in the country. Operated by the Maryland Department of Health, KISS provides:
- Free car seat inspections by certified technicians
- Car seat installation education for parents and caregivers
- Information about car seat recalls and expiration dates
- Low-cost car seat distribution for qualifying families
Parents can locate a car seat inspection station through the KISS program or through the NHTSA car seat inspection locator.
Leaving a Child Unattended in a Vehicle in Maryland
Maryland law makes it illegal to leave a child under 8 years old unattended in a motor vehicle. An unattended child means there is no responsible person at least 13 years old present in the vehicle. Violations can result in a fine of up to $500 or imprisonment for up to 30 days for a first offense.
Smoking in a Vehicle with a Child in Maryland
It is illegal to smoke in a motor vehicle in Maryland when a child under 8 is present. This includes cigarettes, cigars, and pipes. The law aims to protect children from secondhand smoke exposure in enclosed spaces.
Car Seat Replacement Guidelines in Maryland
Maryland does not have a specific law requiring car seat replacement on a set schedule. However, the KISS program and NHTSA recommend:
- Replacing any car seat that has been in a moderate or severe crash
- Checking the manufacturer's expiration date (typically 6 to 10 years from manufacture)
- Never using a car seat with an unknown history, such as one purchased at a yard sale without documentation
- Registering your car seat with the manufacturer to receive recall notices
