Pennsylvania Car Seat Laws: Requirements and Guidelines

Frequently Asked Questions

What Are the Height and Weight Requirements for Car Seats in Pennsylvania?

Pennsylvania law requires children under age 2 to ride on rear-facing seats. The law requires children under the age of 4 to be secured in the appropriate child restraint system (rear-facing or forward-facing seat). Children who have outgrown rear-facing seats should ride on forward-facing seats until at least the age of 4.

What Are the Rear Facing Car Seat Laws in Pennsylvania?

Pennsylvania law requires children under age 2 to ride on rear-facing seats or until the manufacturer's maximum weight and height limits have been exceeded. There are two types of rear-facing seats - infant-only seats and convertible seats. Infant-only seats are designed for newborns and premature babies, however, infants usually outgrow this seat within a short period of time and then transition to convertible seats which allow them to remain rear-facing for a longer period.

What Are the Forward Facing Car Seat Laws in Pennsylvania?

The law requires children under the age of 4 to be secured in the appropriate child restraint system (rear-facing or forward-facing seat). This means children who have outgrown rear-facing seats should ride on forward-facing seats until at least the age of 4. Use a seat that is equipped with a harness and tether. A five-point harness is preferable because it allows you to secure the straps across the child's stronger parts (hips and shoulders).

What Are the Booster Seat Laws in Pennsylvania?

The law requires children of 4-8 years to ride on a booster seat. Booster seats are designed to raise children so that regular seat belts can fit properly. A proper fit means the lap belt lies flat across the upper thighs and the shoulder belt lies snug across the middle of the chest area. An improper fit may result in the lap and shoulder belt crossing the stomach and neck, and this can cause serious injuries to the child in case of an accident.

When Can a Child Sit in the Front Seat in Pennsylvania?

The law does not cover specific requirements for children to sit in the front seat. However, the law requires airbags to be removed or deactivated before a rear-facing child safety seat is installed in the front seat. The Pennsylvania Department of Transportation recommends keeping children in the back seat until they are 13 years old. The back seat is considered to be generally safer, and it's also farther away from the point of impact in case of a head-on collision.

What Are the Laws for Children Between 8 and 18 in Pennsylvania?

Children who are 8 years or older but younger than 18 years are required to ride while wearing seat belts regardless of where they are sitting in the car.

Is it Illegal to Leave a Child Alone in a Car in Pennsylvania?

You are not allowed to leave a child under the age of 6 unattended inside a vehicle. We do not recommend leaving children unattended in your vehicle for any length of time.

Is it Illegal to Smoke in a Vehicle With a Child in Pennsylvania?

Corrected a misattribution: the pre-1966 vehicle exemption in 75 Pa.C.S. 4581 belongs to the general adult seat belt clause, not the child passenger restraint requirement, which carries no model-year exemption.
