Wheel stops may be provided where it is considered necessary to limit the travel of a vehicle into a parking space. Note they should be avoided in any situation where they may be in the path of pedestrians moving to or from parked vehicles, or crossing a car park for any other purpose.

Wheel Stops shall not obstruct accessible travel paths for people with disabilities.

All kerbs, wheel stops, low barriers and other obstructions that could be a tripping hazard to pedestrians shall be surfaced in a colour contrasting with their surroundings.

Wheel stops are typically used to:
(i) limit kerb overhang which is inconvenient or hazardous for pedestrians.
(ii) inhibit contact with an end barrier or high kerb.
(iii) inhibit encroachment into an opposing parking space.
Wheel stops shall be:
(i) Between 90 and 100 mm in height, and
(ii) 1650 ±50 mm in width.

Positioning of wheel stops:
If reverse-in parking is likely and encroachment over the end of the parking space cannot be tolerated, wheel stop positions shall be set at the rear-in position and all vehicles required to back in.
