Where must a child under 8 ride in a car in California?
You are driving a 6-year-old who is 4 feet 2 inches tall. Where and how must the child ride?
The answer
A child under 8 must use a child restraint system in a rear seat, apart from the listed exceptions. At 8 or older, or at least 4 ft 9 in, a properly fitted seat belt may be used.
The handbook says children under 8 must use a child restraint in a rear seat. Children under 2, under 40 pounds and under 3 ft 4 in must be in a rear-facing restraint and may not ride in the front seat of an airbag-equipped vehicle.
A child who is 8 or older, or at least 4 ft 9 in, may use a properly secured seat belt that meets federal standards. The CHP guide says to check the fit: the belt should sit low on the hips and across the shoulder and collarbone.
Exceptions
- The handbook lists front-seat exceptions: no rear seat exists, rear seats are side-facing jump seats or rear-facing, the restraint cannot be installed properly in the rear, all rear seats are occupied by children 7 or younger, or a medical reason.
Why this rule matters for safety
Adult seat belts do not fit small children and can injure them in a crash. A fitted restraint in the rear seat protects them, and the rear seat also keeps them away from front airbags.
