Child car restraint requirements in Western Australia

Posted on: Monday, 15 May 2017 at 12:00:00 AM

Using an appropriate child car restraint can greatly reduce the risk of death or serious injury to a child in the event of a crash.

The effectiveness of a child car restraint is dependent on correct installation.

The following information is intended as a quick reference guide to using child car restraints in Western Australia:

  • Children from birth up to the age of six months must be in a rearward facing child car restraint (capsule or rearward convertible).
  • Children from six months up to the age of four years must be in either a rearward or forward facing restraint with an internal five point harness.
  • Children from four years up to the age of seven years must be restrained in either a forward facing restraint with an internal five point harness or a booster seat restrained by a lap sash seat belt or child safety harness.

A child aged six months or more must remain rearward facing until they reach at least the minimum height markers required in forward facing mode.

A child aged four years and above can use a booster seat once they reach the minimum height limit for the booster seat being used.

Many booster seats will allow a child to remain in them until well past 7 years old, with some allowing children to use them until approximately 10 years of age.
