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.
South 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.
The South 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.

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.

Australian Road Rules Review
MACA welcomes and strongly supports updates to child restraint rules in the Australian Road Rules. Proposed changes being considered are outlined in the National Transport Commission (NTC) Issues Paper. As a member of the NTC’s Expert Advisory Group, MACA actively contributed to the development of the paper.
A summary report outlining the feedback received during the consultation is available on the NTC website.
Next steps
The NTC will use feedback from the Issues Paper consultation to inform the development of a regulation impact statement.
A further round of public consultation is expected mid-2026.

Improving access to specialty products
From 30 March 2024, South Australian families of children with disability no longer need to attend the Department for Infrastructure and Transport’s (DIT) office in Regency Park in person for a vehicle inspection to use a speciality child restraint that has been prescribed for their child’s needs.
This follows three years of advocacy from MACA to remove unnecessary laws and processes impacting on families' access to and use of specialty products, such as special purpose car seats.
