Child Car Seat Laws

The California Child Car Seat Installation, Inspection & Instruction Law is in effect as of January 1, 2013.


  • Infants under the age of one and weighing no more than 35 pounds should be in an infant-only, rear-facing child safety seat (or a convertible child safety seat turned to face the rear of the vehicle), installed in the back seat.
  • Children between the ages of one and four and weighing between 20 and 40 pounds can be in a forward-facing, forward-facing only, or convertible child safety seat, or a high-back booster or harness, installed in the back seat of the vehicle.
  • Children between the ages of four and eight can be in a high-back or no-back belt-positioning booster, installed in the back seat of the vehicle. If the child is under the age of eight, but at least four feet and nine inches tall, a booster isn't required.

As of January 1, 2012 California Booster Seat Law prohibited parents, guardians, or drivers from transporting on a highway in a motor vehicle any child under 8 years oldor under 4 feet 9 inches without securing that child in a child restraint which meets federal motor vehicle safety standards. In addition, all kids younger than eight, must be secured in the back seat.
