These signs help maintain safety and order by indicating speed limits, parking restrictions, and other rules. Common examples include stop signs, yield signs, and speed limit signs. These signs are usually rectangular or square and often feature red, white, or black colors. They are designed to be easily recognizable and understandable, ensuring that all road users can comply with the regulations. Following regulatory signs is crucial for safe driving and preventing accidents.
