Additional signs – clarification for traffic control

Additional signs are used alongside main signs to provide extra information that is not evident from the traffic sign alone. They can specify how far the sign is valid, which vehicles it applies to, or the time period it is restricted to. This improves traffic flow and safety by offering road users precise information.
