Pennsylvania car seat laws are a little unusual in that the requirements are age-based only. There are no height or weight references or exclusions, except to state that a child must ride in a car seat or booster seat appropriate for his or her weight and height.

In Pennsylvania, infants must ride rear facing until at least age 2. Kids under 4 must ride in an appropriate child safety seat. Kids age 4 through age 7 must ride in either a safety seat or a booster seat.

All kids under 18 must to buckle up. Kids are safer in the back seat until age 13.

Pennsylvania’s child passenger safety law is primary, which means police can pull over any vehicle if they suspect a child under 8 is not properly restrained. Fines for this infraction are $75 plus court costs, but this is adjusted annually.

According to best practices by safety experts, kids are safest riding in each stage of safety seat until they reach the maximum height or weight limit for the seat. Only then should they move on to the next stage.

ALWAYS use booster seats with BOTH a shoulder belt and lap belt. Using a booster without a shoulder belt eliminates upper body protection and increases risk of severe injury.

Kids should continue to use a booster seat until an adult seat belt fits correctly, usually around 4′-9″ (57″) tall. This means a child can sit comfortably against the seat back (no slouching) with their knees bent at the seat front. The shoulder belt will cross the shoulder and chest, avoiding the neck and face. The lap belt will cross over the upper legs, not the stomach.
