The facts

On average 34 people are killed in road crashes in WA each year while not wearing a seat belt. Wearing a seat belt is one of easiest ways to protect drivers and passengers in a vehicle. You are 10 times more likely to be killed in a road crash if you’re not wearing a seat belt in a car.

In the event of a crash seat belts:

  • prevent ejection from vehicle
  • decrease the time it takes for an occupant to come to a stop
  • spread the impact force over a greater area of the body, and
  • minimise contact with the interior of the vehicle

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.

Use the Road Safety Commission’s Child Car Restraint Calculator to ensure your child has the appropriate restraint.

Western Australian laws specify by age the type of child car seat or seat belt 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 seat belt or child safety harness.
