Mandatory signs give an instruction which you are obliged to follow. For example, they might tell you that you have to drive in a particular direction. If a mandatory sign indicates that a certain type of traffic is permitted then this means that all other traffic is prohibited. For example, a pedestrian path may only be used by pedestrians and all other traffic is prohibited.
