Child Restraint Laws

California Vehicle Code requires children to be secured in an appropriate child passenger restraint (safety seat or booster seat) in the back seat of a vehicle, until they are at least 8 years old or 4 feet 9 inches tall.

  • Seat can never be forward facing.

Facts About Child Restraint Use

National Highway Traffic Safety Administration (NHTSA)

  • Motor vehicle crashes are the leading cause of death for the age group 4 through 15.
  • Of the 459 occupant fatalities among children from birth through age 4 in 2002, nearly 40 percent were completely unrestrained.
  • In a 2004 study conducted for NHTSA, misuse of child restraints was approximately 73 percent.  The most common problems were loose harness straps securing the child to the seat and loose attachment of the child safety seat to the vehicle.


During 2006, a total of 1,537 children from birth through age 15 were killed in passenger vehicle crashes.  Approximately 50 percent of passenger vehicle occupants in this age group were unrestrained.  The breakdown by age group was:

    • 34 percent of children from birth through age 4 were unrestrained.
    • 40 percent of children ages 5 through 7 were unrestrained.
    • 52 percent of children ages 8 through 12 were unrestrained.

If 100 percent of motor vehicle occupants younger than age 5 had been protected by child safety seats, an estimated 518 lives (an additional 98 lives) could have been saved in 2006.

From 1975 through 2008, an estimated 8,959 lives were saved by the use of child restraints (child safety seats or adult belts).
