The two forms of road signs are regulatory and informative.
Regulatory signs are designed to give drivers specific instructions or prohibitions, such as speed limits, stop signs, or no parking zones. They help regulate traffic flow and ensure the safety of drivers, pedestrians, and other road users.
Informative signs, on the other hand, provide drivers with information about the road ahead, such as upcoming exits, destinations, or distances. They may also provide guidance on services available, such as rest areas, fuel stations, or emergency services. These signs are designed to help drivers navigate the road network and plan their journey effectively.
