Road signs are important visual signals that provide information to drivers and pedestrians. They help ensure safety by indicating rules, warnings, and directions. Common types of road signs include stop signs, yield signs, and speed limit signs, each designed to convey specific messages quickly and clearly. These signs are standardized in many countries, using shapes and colors to communicate effectively. For example, red typically indicates a prohibition, while green signals permission or guidance. Understanding road signs is essential for safe navigation on roads and highways, helping to prevent accidents and maintain order in traffic.
