Pennsylvania Child Car Seat Laws (2025)

As of January 2025, Pennsylvania has specific laws regarding child passenger safety to ensure the well-being of young passengers. In this article we outline age-appropriate car seat and booster seat requirements, as well as general safety guidelines in PA. 

What is The Car Seat Law in Pennsylvania? 

Pennsylvania car seat laws require children to use appropriate restraints based on weight and age:

• Infants & Toddlers (0-2 years): Rear-facing car seat until at least 2 years old.
• Young Children (2-4 years, under 40 lbs): Forward-facing car seat with a harness.
• Children (4-8 years, over 40 lbs): Booster seat until 8 years old.
• Older Children (8-12 years, over 80 lbs): Seat belt if they fit properly.

Current Laws For Car Seats in Pennsylvania (PA):

Rear-facing Car Seats: Birth to age 2

Pennsylvania law requires children under two years old to be secured in a rear-facing car seat. Children must remain rear-facing until they exceed the seat’s height and weight limits. Failure to comply can result in a fine. The law follows recommendations from the American Academy of Pediatrics.

Rear-facing car seats significantly reduce the risk of severe injury or death in the event of a car accident. It is crucial to consult the specific instructions and weight/height limits provided by the car seat manufacturer and to seek guidance from a certified child passenger safety technician for proper installation and usage.

Forward-facing seats: Ages 2 to 4

In Pennsylvania, children aged 2 to 4 must be properly restrained in a forward-facing car seat with a harness system. This ensures optimal safety and protection during travel.

Booster Seats: Ages 4 to 8

Pennsylvania’s car seat laws require children under 2 years old to be secured in a rear-facing car seat. Children between 2 and 4 years old must use a forward-facing car seat with a harness. Kids aged 4 to 8 must be in a booster seat. All children under 8 must be in an appropriate child restraint system.

Booster seats are essential for ensuring proper seat belt fit, positioning the lap belt across the child’s hips and the shoulder belt across their chest and shoulder. This positioning optimizes safety by distributing the force of a crash impact over the strongest parts of the child’s skeleton.

Seat Belts: Ages 8 to 18

Pennsylvania law mandates that all children aged 8 to 18 must wear a seatbelt while traveling in a motor vehicle.

While there is no specific law in Pennsylvania prohibiting children from sitting in the front seat, airbags pose serious risks to young passengers, the Pennsylvania Department of Transportation strongly recommends that children under 13 ride in the back seat. 

Penalties for Violating Pennsylvania’s Child Passenger Protection Law

Violations of Pennsylvania’s child passenger safety laws can carry fines. However, there may be opportunities to mitigate the penalty. If the driver can provide proof of acquiring an appropriate child passenger restraint system (such as a car seat or booster seat) after receiving the citation, the fine may be dismissed. This provision aims to encourage compliance with the law and ensure the safety of children traveling in vehicles.

How to Ensure Proper Car Seat Installation

Step1: Refer to your car seat’s instruction manual and your vehicle owner’s manual.

Step 2: Ensure the car seat is securely fastened and does not move more than an inch in any direction.

Step 3: Attend a Car Seat Check through CHOP or another certified program to have a professional inspect your installation.
