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 communicate specific messages quickly and clearly. These signs are standardized in many countries, using shapes and colors to convey their meanings. For example, a red octagon typically indicates a stop, while a yellow diamond warns of potential hazards ahead. Understanding road signs is essential for safe navigation on roads and highways.
