Warning signs alert you that there may be dangers or changed road conditions ahead. The signs are usually diamond-shaped with pictures, diagrams, symbols or words in black on a yellow background.
These are some of the most common warning signs.

Advisory speed sign
Sometimes an advisory speed sign is used with a warning sign. For example, to show the maximum speed that’s safe in good conditions, or how long you should look out for a particular hazard.
Variable message sign
Some roads have large electronic signs (called variable message signs). These signs warn you of changes in traffic conditions ahead – for example, fog, a crash, roadworks, congestion, road closures or police operations.
