Regulatory traffic signs

This section includes the signs that show a road regulation is in place. These must be obeyed.

Regulatory signs show the course a driver must follow and an action they are required to take or forbidden to take. They are usually circular and have a red border and black symbols or letters on a white background. Mandatory regulatory signs that indicate the direction traffic must take at junctions are blue and white.

The following is an alternative design for the 80kmh speed limit sign. This sign may be provided:

On a local road to indicate that a speed limit of 80kmh applies; or
At a location where special speed limit bye-laws specify that the special speed limit of 80kmh applies in respect of a local road or part of a local road in a built-up area.
