When are road signs primarily used?

Road signs play a crucial role in ensuring the safe and efficient operation of roadways. Their primary purpose is to provide important operational and safety instructions to drivers. This includes conveying rules about speed limits, indicating when to stop or yield, and alerting drivers to potential hazards, such as curves, intersections, or construction zones. By following these signs, drivers can make informed decisions that contribute to road safety for themselves and others.

While some signs might also inform about local attractions or road conditions, these are secondary to their main function of guiding drivers and enhancing safety. Aesthetic purposes are not a factor in the design or placement of road signs, as their main focus is functionality and the clear communication of critical information.
