Warning Signs

The essentials

Warning signs give advance notice of possible hazards or changes in road conditions. This topic helps recognize their general appearance and understand what conditions require advance speed reduction or increased attention.

What to remember

Warning signs generally do not command ‘stop’; they warn in advance of hazards such as bends, intersections, pedestrians, roadworks or slippery sections. The correct response is usually to adjust speed and attention so that you are ready to act when the hazard is reached. A supplementary plate may specify the distance to the hazard or the extent of the hazardous section.
