Child Restraints

California has strict child passenger safety laws to protect kids:

Children Under 2 Years Old

  • Must ride in a rear-facing child safety seat unless the child:
    • Weighs 40 or more pounds, or
    • Is 40 or more inches tall
  • Rear-facing seats offer better support for infants’ heads, necks, and spines.
  • Never place a rear-facing seat in front of an active airbag – it’s dangerous.
  • The back seat is the safest place.

Children Under 8 Years Old (or Under 4’9” Tall)

  • Must be secured in a child safety seat or booster seat in the back seat.
  • Progression of restraint:
    • Rear-facing seat (until at least age 2 and until maxing out limits)
    • Forward-facing harness seat
    • Booster seat (until seat belt fits properly)
  • Booster lifts child so seat belt fits correctly.

Back Seat Requirement

  • Children under 8 must sit in the back seat, not the front,
    • Unless:
      • The vehicle has no rear seats
      • The rear seats are side- or rear-facing jump seats
      • There is a medical necessity (with a doctor’s note)
      • All rear seats are occupied by younger children
  • Back seat is much safer in a crash due to distance from airbags and frontal impacts.

Children 8 to 16 (or 4’9” and Taller)

  • Must wear a seat belt properly.
  • They may use the vehicle’s regular seat belt if it fits:
    • Lap belt low on hips, touching thighs
    • Shoulder belt across the chest
  • If the belt doesn’t fit properly, a booster seat is still recommended.
  • Many kids need a booster until age 10–12 for proper belt fit.
  • Legally at age 8 or 4’9”, the booster is no longer required, but may still be safest.

Penalties

  • Fines are significant for failing to properly restrain a child.
  • The driver receives a point on their driving record.
  • More importantly, unrestrained children can be seriously injured or killed even in minor crashes.
