The most common rules for New South Wales are summarised below.

Road rules

There are different rules for transporting children under 7 years, and children 7 to under 16 years, and vehicle standard exemption requirements for the legal use of seatbelt buckle covers.

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 harness/vest the following road rules must be complied with.

Seatbelt buckle covers

The NSW Vehicle Standards Information 49 (VSI 49) provides the conditions that must be met for the legal use of a seatbelt buckle cover, without needing to apply to Transport for NSW for approval.

VSI 49 requires the following:

  • medical certificate to be carried in the vehicle with the buckle cover manufacturer’s instructions attached.
  • the seatbelt buckle cover must comply with AS 4370:1996 (note this standard is out of date) and be fitted in accordance with manufacturer’s instructions.
  • the seatbelt buckle cover must be removed when not being used by the nominated person.

NOTE: VSI 49 has not been updated since 2007 and includes out-of-date information. MACA has requested that VSI 49 be reviewed. MACA has been advised by Transport for NSW that VSI 49 is being updated.

For more information refer to MACA's buckle cover model policy.

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.

Disclaimer: The Advice to Parent form is only for use by MACA trained professionals. MACA bears no responsibility for unauthorised use of this form.
