38. Turn prohibition
A turn prohibition prevents drivers from turning in the direction indicated by a traffic sign. It may prohibit a left turn, a right turn or a U-turn at an intersection or along a specified section of road.
Drivers must continue along a permitted route and follow any lane arrows or mandatory-direction signs. A turn prohibition does not itself determine priority or speed, and any exemption for cyclists, public transport or other road users must be expressly indicated.

What is a turn prohibition?
A turn prohibition prevents drivers from making a particular turn or change of direction indicated by a traffic sign.
Is a prohibited turn the same as a mandatory direction?
No. A prohibition sign identifies a movement that may not be made. A mandatory-direction sign identifies the direction or directions that must be followed.
Does a turn prohibition change priority?
No. Drivers making another permitted movement must still follow traffic lights, priority signs and the ordinary rules concerning pedestrians, cyclists and other vehicles.
Does a turn prohibition impose a speed limit?
No. The applicable general, zonal or posted speed limit remains in force.
Must you use an indicator for a permitted turn?
Yes, where local law requires it. Signal early enough to communicate your intention and stop signalling after completing the movement.
