Warning signs

What do warning signs look like?

Warning signs are triangular with a white background, red border and black symbols. There are exceptions to this rule of thumb. They alert you to particular dangers — places on the road where you need to be extra attentive and drive at a low enough speed to handle the hazard.

Is the speed bump warning sign important for the theory test and the practical driving test?

The speed bump warning sign is important both on the theory test and during the practical driving test. On the theory test you may be asked what the speed bump warning sign warns about and how you should react. During the practical driving test you must show that you recognize the speed bump warning sign, slow down in time, and drive safely over the bumps.

What is the speed bump warning sign?

The speed bump warning sign warns that a raised section of the road is coming, also called a speed bump or speed hump. The sign is triangular with a red border and a black, wave-shaped symbol showing bumps in the road.

When do you encounter the speed bump warning sign?

You often find the speed bump warning sign in:

Residential areas – to slow speeds where children and pedestrians are present.
School routes – to ensure a safe route to school.
Narrow or winding roads – where visibility or road design requires low speed.

In the picture you see the speed bump warning sign that warns before a section with several bumps.

What happens if you drive too fast over the speed bump?

If you drive too fast over the speed bump, you can lose control, damage the car, and create discomfort for the passengers. In the worst case you can lose control and crash. During the practical driving test, the examiner assesses whether you adjust your speed to the conditions.

Why is the speed bump warning sign important?

The speed bump warning sign helps reduce speed in areas with vulnerable road users. By warning about bumps it gives you time to slow down and drive safely, which reduces the risk of accidents.

Supplementary signs with the speed bump warning sign

The speed bump warning sign can have supplementary signs such as:

802 Distance – tells how many meters there are to the first speed bump.
804 Extent – indicates the length of the section with several speed bumps.

Supervised driving and the speed bump warning sign

When you are supervised driving, the accompanying driver is mainly responsible for safety and that speed rules are followed. You should slow down at the speed bump warning sign to avoid discomfort and to show good control during the practical driving test.

Can the speed bump warning sign have supplementary signs? – Yes, supplementary signs for distance (802) or extent (804).
Do I have to stop at the speed bump? – No, you only need to slow down enough to drive safely over the bumps.
