Marker signs
What do marker signs look like?
Marker signs are square and have yellow symbols on a black background, or black symbols on a white background. There are exceptions to this rule of thumb. Marker signs provide information about how the road continues or about obstacles on or near the roadway.

The sign indicates a sharp curve ahead, and you must reduce your speed considerably. It is placed perpendicular to the road so you see it as you approach the curve. This variant marks a left-hand curve.

Is the background marker important for the theory test and the driving test?
The background marker is part of the curriculum, but it is not the most important thing you need to know for the theory test or the driving test. Even so, it is a good idea to know what it means.
What is a background marker?
A background marker is a sign used in sharp curves or at T-junctions (an intersection with three roads). The sign indicates that the speed limit is too high for the curve, and that you must slow down before entering the curve. At T-junctions it is used if there are not enough other signs warning about the intersection. This sign also shows that the curve goes to the left.
When the sign is yellow and red, it is temporary.
When you see this sign, you must remember to slow down in good time. If you drive too fast, you may end up driving off the road.
