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.
