South Australia

Understanding road laws


When children are prescribed special purpose car seats, modified Australian standard car seats, specialty harnesses/vests, and other devices (e.g seatbelt buckle covers) there are specific road rules that must be complied with in South Australia.

The most common rules for South Australia are summarised below.

There are different rules for transporting children under 7 years, and children 7 to under 16 years.

If a child with disability or medical condition (under 16 years of age) is prescribed a special purpose car seat, modified Australian standard car seat, or specialty harness/vest the following road rules must be complied with.

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.

Read more about these welcome changes in our media release.

Advice to Parent form

MACA recommends an Advice to Parent form be carried in each vehicle the child travels in. In some states and territories, this is a legal requirement.

The MACA Guide, provided free to participants of our online training course, includes detailed information to assist prescribers in completing the form.
