Speed Limits

There are two types of roads in the district – Council owned roads and the main roads that are owned and managed by the state government Department of Planning, Transport and Infrastructure (DPTI).

DPTI are the only authority with the legislative power to set and change speed limits. DPTI have produced a Speed Limit Guideline for South Australia document that provides a point of reference for applying speed limits throughout South Australia to make roads, roadsides and road-related areas safer for all road users.

Speed Limit Signage

Current legislation in SA does not allow speed limit signage on unsealed roads, and drivers should drive to the conditions.

Installation of new speed limits signs must be approved by DPTI as the speed limit authority.

Speed limit signs are typically displayed on main roads entering townships to signal the transition to a new speed zone.

If you believe a speed limit sign is missing or is warranted please contact us. Please provide in the request;

  • your name, address, and contact details 
  • location of road and required sign
  • why the sign is required and the observations

Speed Limit Reviews

The DPTI document (mentioned above) sets out the process for Council to review and approve requests change speed limits on roads. See Section and 2.5.3 for detailed information.

Council can request a speed limit review by DPTI of a sealed road where it feels an investigation is warranted.

Before requesting a speed limit review by DPTI, Council will assess the road against a number of criteria, including:

  • Traffic counts and function of road
  • Average speeds (based on traffic surveys)
  • Level of development and access points onto the road
  • Roadside hazards and number of crashes in past 5 years

If the road meets the criteria for further review, it will be sent to DPTI to request a review, where a similar but more rigorous process is undertaken.
