9. Advisory speed

An advisory speed is a recommended speed for a particular road section or hazard rather than a legally imposed maximum speed. It may be shown near bends, junctions, steep gradients, roadworks or other locations where a lower speed can help drivers negotiate the road safely.

Drivers should treat an advisory speed as guidance for safe driving conditions and should travel even more slowly when weather, visibility, traffic or road conditions require it. A separate legally binding speed limit must still be obeyed.

What is an advisory speed?

An advisory speed is a recommended speed intended to help drivers negotiate a road section or hazard safely.

Is an advisory speed the same as a speed limit?

No. An advisory speed normally provides guidance, while a regulatory maximum-speed sign establishes a legally enforceable speed limit.

Can you drive slower than an advisory speed?

Yes. Drivers should reduce their speed further whenever road, traffic, visibility or weather conditions make the recommended speed unsafe.
