Road signs are primarily precautionary devices used to guide road users. They are designed to provide important information to drivers and pedestrians, such as speed limits, traffic rules, directions, warnings, and hazards. The purpose of road signs is to help ensure the safety of all road users by providing them with the necessary information to navigate roads, intersections, and other traffic situations safely and efficiently. Road signs are an essential part of road safety and are meant to be understood by everyone regardless of their language or literacy level.
