South Australia
Understanding road laws

Introduction
This page explains the main road rules in South Australia for travelling in cars. These rules include exemptions where a person with a disability or medical condition needs an alternative restraint or method of travel.
But research shows these exemptions don’t always keep people safe. To support safer outcomes, we recommend seeking an assessment from a MACA trained allied health professional.
To improve protection for children with disabilities and medical conditions under the road rules, we successfully advocated for the current review of the Australian Child Restraint Road Rules to be inclusive of children with disabilities and medical conditions.
The National Transport Commission is now leading an inclusive review, and we are participating in the review’s Expert Advisory Group.

South Australian road rules
The South Australian Road Rules provide requirements for how people must be restrained when travelling in a motor vehicle, in the following age groups:
• Under 6 months
• 6 months to under 4 years
• 4 years to under 7 years
• 7 years to under 16 years
• 16 years and over
The rules define approved vehicle restraints, which are generally Australian standard car seats and seatbelts that comply with the Australian Design Rules. The type of vehicle restraint required will depend on the person's age and size.
Where a person with a disability or medical condition is unable to travel in an approved vehicle restraint, there are road rule exemptions that allow the person to travel in an alternative way. There are conditions that must be complied with, such as a medical certificate.

Exemptions
An exemption is required when a person is prescribed a non-approved vehicle restraint, or is unable to wear the seatbelt properly adjusted and fastened. Examples of alternative methods of travel include:
- special purpose car seat
- modified Australian standard car seat
- specialty harness/vest
- additional recline (which may mean the seatbelt is not being worn properly adjusted and fastened)
- in rare cases, no child restraint or vehicle seatbelt
There is also an exemption to allow a child under 7 years to travel in the front row of a vehicle, which has two or more rows, due to their disability or medical condition.
The most common exemption road rules for South Australia are summarised below.
MACA Certified Professionals can help families and clients comply with these requirements.

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.

Transport safety advice for parents/clients
MACA recommends that a Transport Safety Advice Form be completed by a prescriber (e.g., occupational therapist) where a person with disability/medical condition has been assessed and prescribed an alternative method of travel.
It is recommended that this advice to parent/client form is carried in the vehicle the person travels in at all times as it provides important information about the prescribed method of travel.
This form has been developed for use by MACA Certified Professionals and is available from MACAhub Pro.
