Children under 2 and 30 pounds ride rear-facing with a 5-point harness; under 4 and 40 pounds in a 5-point harness; under 8 and 57 inches in a harness or booster. All of these must be in a rear seat.
Is the New Jersey car seat law changing?
No. As of October 6, 2026, when SeatChecker last checked the statute, no enacted change to the New Jersey car seat law is scheduled. Current law: Children under 2 and 30 pounds ride rear-facing with a 5-point harness; under 4 and 40 pounds in a 5-point harness; under 8 and 57 inches in a harness or booster. All of these must be in a rear seat.
When can my child stop using a booster in New Jersey?
Once the child is 8 years old or 57 inches (4 feet 9 inches) tall. Pediatricians recommend keeping a child in a booster until the seat belt actually fits.
What age can a child sit in the front seat in New Jersey?
In New Jersey, the front-seat rule comes from the back-seat law. A child under 8 and under 57 inches must ride in a rear seat. If the vehicle has no rear seats, the child may be in the front, but a rear-facing seat may not be in front of an active passenger airbag. The American Academy of Pediatrics recommends the back seat for all children under 13. That is best practice, not a legal requirement in New Jersey.
What is the fine for a car seat violation in New Jersey?
A violation carries a fine in the $50 to $75 range, with the exact amount set within that range by the court.
