The Car Seat Rules

In Pennsylvania, the operator of a passenger car, Class I or II truck, motor home, or classic or antique vehicle fastens a child in a restraint suited to the child's age, anywhere in the vehicle including the cargo area.
- Under two years of age: a rear-facing child passenger restraint system, used until the child outgrows the manufacturer's weight and height limits.
- Under four years of age: a child passenger restraint system.
- Four years of age or older but under eight: a fastened seat belt and an appropriately fitting booster seat.
- Eight years of age or older but under 18: a properly adjusted and fastened seat belt, which the driver secures or causes to be secured.
Adults. Each driver and front seat occupant wears a properly adjusted and fastened seat belt, apart from listed exemptions such as a written medical verification.
