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. 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.

2. Pass obstacle on the right

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

3. Mandatory right

This traffic sign indicates a mandatory direction to the right. Traffic must proceed to the right at the sign and may not continue straight ahead or to the left.

4. Road with two-way traffic

This traffic sign indicates the start of two-way traffic. From this point, traffic may travel in both directions on the road. Be prepared for oncoming vehicles.
