Understanding road laws
Safe car travel
Safe and comfortable car travel is important for everyone.
Car seats, booster seats and seatbelts help protect passengers if a vehicle stops suddenly or is involved in a crash. Using the right restraint for a person’s size and needs can reduce the risk of serious injury or death.
Western Australian road rules
If a person with disability or a medical condition can travel safely in a standard Australian child restraint, booster seat or vehicle seatbelt, the table below shows the minimum legal requirements and best practice recommendations for safer travel.

Alternative restraints and methods of travel
Some people with disability or a medical condition cannot travel safely using a standard child restraint, booster seat or vehicle seatbelt.
Western Australian road rules include provisions that may allow alternative methods of travel for people with disability or medical conditions. The requirements depend on the person’s age and how they need to travel.
Alternative methods of travel may include:
- special purpose car seats
- modified child restraints or vehicle seatbelts
- specialty harness/vests
- buckle covers
- extra recline or positioning supports
- travelling in the front row of a vehicle when the person is under 7 years of age
- in rare circumstances, travelling without a child restraint or seatbelt.
A medical certificate and/or other approval may be required. A MACA Certified Professional can help with transport assessments and documentation.

Seatbelt buckle covers
A seatbelt buckle cover may be considered where a person is repeatedly releasing their seatbelt and this creates a safety risk.
In Western Australia, approval is required to legally use a seatbelt buckle cover.
Because buckle covers can introduce additional safety risks, including making it harder to release a person quickly in an emergency, they should only be considered following an appropriate assessment.
A MACA Certified Professional can assess the person’s transport needs and help with the requirements for using a buckle cover.

School and community transport
Children and adults with disability may need additional supports, an alternative restraint or another travel arrangement when using school, community or other organised transport services.
In addition to road-rule and vehicle-standard requirements, transport providers, schools and organisations may have their own policies and approval processes.
If a person is having difficulty travelling safely, speak with the relevant transport provider or organisation and consider seeking an assessment from a MACA Certified Professional.

- assess transport needs
