Child Passenger Safety When it comes to selecting the right car seat for your child, one size does not fit all. There are three types of car seats: rear-facing, forward-facing, and the booster, with each best suited to protect a child based on their age and size. California’s Occupant Protection Law California law requires all children under two years old to ride in a rear-facing car seat, unless the child weighs 40 or more pounds OR is 40 or more inches tall. Children under the age of 8 are required to be secured in a car or booster seat. Children who are 8 years old OR at least 4’9” may be secured by a booster seat, but at minimum wear a seat belt. Choosing A Car Seat Keep your child in rear and forward-facing seats as long as possible. Do not rush to move a child into a booster seat before they are ready. Booster seats are recommended until a child reaches a height of 4’9”. All children 13 and under should ride in the back seat.
