A road sign is a visual indicator placed along roads to provide important information to drivers and pedestrians. These signs can convey various messages, such as traffic regulations, warnings about hazards, or directions to specific locations. Common types of road signs include stop signs, yield signs, and speed limit signs. Road signs are designed to be easily recognizable and understandable, often using symbols and colors to convey their messages quickly. For example, a red octagon typically indicates a stop sign, while a yellow diamond warns of potential dangers ahead. Proper adherence to road signs is crucial for maintaining safety on the roads.
