Mandatory signs

A mandatory sign is a traffic sign that tells drivers what they must do. Instead of prohibiting actions, these signs impose obligations such as following a specific direction, using a particular lane, or keeping a minimum speed. Their purpose is to guide traffic safely and efficiently by ensuring that all road users follow the same required behaviour in places where it is necessary for order and safety.

1. Mandatory roundabout direction

This traffic sign indicates the mandatory direction around a roundabout. Traffic must circulate in the direction shown by the arrows. The sign does not itself determine priority; follow the applicable priority signs, traffic signals and local rules.

2. Turning right mandatory

This traffic sign indicates that turning right is mandatory at the junction ahead. Traffic must turn right and may not continue straight ahead or turn left.

3. Pass obstacle on the left

This traffic sign indicates that traffic must pass an obstacle on the left. Keep to the left of the obstacle and follow any accompanying signs or road markings.

4. Driving straight ahead or turning right mandatory

5. Driving straight ahead mandatory

This traffic sign indicates that driving straight ahead is mandatory. Traffic must continue straight ahead and may not turn left or right at the location to which the sign applies.

6. Mandatory path for cyclists

This traffic sign indicates a mandatory path for cyclists. Cyclists must use the designated path where the sign applies. Other road users may use the path only where the applicable signs or local rules permit them to do so.

7. Mandatory shared pedestrian and cycle path

This traffic sign indicates a mandatory shared path for pedestrians and cyclists. Pedestrians and cyclists must use the same designated path rather than separate sections. They must share the space safely and follow the applicable local rules.

8. Start of a minimum speed

This traffic sign indicates the start of a minimum speed. Road users covered by the sign must travel at or above the indicated speed when conditions allow. Driving more slowly may still be necessary because of traffic, weather, road conditions or another safety-related reason.
