Regulatory signs are important traffic signs that inform drivers of the laws and regulations they must follow on the road. These signs help maintain safety and order by indicating speed limits, parking rules, and other essential driving regulations. Common examples include stop signs, yield signs, and speed limit signs. These signs are usually rectangular or square and often feature bright colors like red, white, and black to grab attention. By obeying regulatory signs, drivers can help prevent accidents and ensure a smoother flow of traffic. Understanding these signs is crucial for all road users, including pedestrians and cyclists.
