Intersection Speed Zones

We’re putting in Intersection Speed Zones at intersections which have a high crash rate and where we know having lower speeds approaching the intersection will help improve people’s safety.

About Intersection Speed Zones

Intersection Speed Zones are electronic signs that detect when someone is turning into or out of a side road and temporarily reduce the legal speed limit on the state highway (usually from 100 km/h to 60km/h or 70km/h). They also do this when someone is crossing the state highway from a side road. Intersection Speed Zones are sometimes called rural intersection activated warning signs or RIAWS and are already being successfully used at 13 locations on state highways around the country to improve intersection safety with minimal delays for road users.
