Safety Tips

Make Safe Choices

  • Select a car seat based on your child’s age and size. Choose a seat that fits in your vehicle, and use it every time.
  • Always refer to your specific car seat manufacturer’s instructions (check height and weight limits) and read the vehicle owner’s manual on how to install the car seat using the seat belt or lower anchors and a tether, if available.
  • To maximize safety, keep your child in the car seat for as long as possible, as long as the child fits within the manufacturer’s height and weight requirements.
  • Keep your child in the back seat at least through age 12.

California Car Seat Law

California law requires all children under two years old to ride in a rear-facing car seat, unless the child weighs 40 pounds or more, OR is 40 inches or more tall.

Children under the age of 8 are required to be secured in the back seat in a car seat or booster seat. Children who are 8 years old OR at least 4’9” may be secured by a booster seat, but at a minimum, wear a seat belt.
