Age for booster seat NJ
In New Jersey, children are required to use booster seats until they meet one of two criteria:
- Age: They turn 8 years old.
- Height: They reach 4’9″ (57 inches) tall.
So, as long as a child is under 8 years old and under 4’9″ tall, they must use a booster seat while riding in the back seat of a vehicle.
Here’s a breakdown of New Jersey’s child passenger safety law:
- Under 2 years old and 30 pounds: Rear-facing car seat with a 5-point harness.
- Under 4 years old and 40 pounds: Forward-facing car seat with a 5-point harness.
- Under 8 years old and 57 inches tall: Booster seat with a lap belt properly positioned across the upper thighs and shoulder belt across the chest.
- 8 years old or 57 inches tall: Seat belt properly adjusted (lap belt across upper thighs and shoulder belt across chest/collarbone).
Even though it’s not legally required, some safety experts recommend children use booster seats until they reach 4’9″ tall, regardless of age. This is because even at 8 years old, a child’s body proportions may not be mature enough for the adult seat belt to fit properly in a crash.
