Child car restraints

The age and height of a child should be taken into consideration when choosing the appropriate car restraint for your child. Avoid old or worn restraints, that are more than 10 years old or have previously been in a crash. And ensure your child car restraint has been correctly installed in your vehicle.

Western Australian laws specify by age the type of child car seat or seatbelt that a child should use:

  • Birth to under six months to be restrained in a rearward facing child restraint (e.g. infant capsule).
  • Six months to under four to be restrained in either a rearward or forward facing child restraint with in-built harness.
  • Four to under seven to be restrained in either a forward-facing child restraint or booster seat restrained by a correctly adjusted and fastened seatbelt or child safety harness.
