Road laws

On 25 September 2020, Western Australia introduced new laws relating to transporting children (under 16 years) with disabilities and medical conditions in motor vehicles.

The law exempts a child with a disability or medical condition from travelling in an Australian standard car seat providing certain conditions are met.

Advice to Parent form

The Advice to Parent form, together with the medical certificate, must be carried by the driver in the vehicle the child is travelling in at all times.

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