A speed limit sign is a traffic sign that displays the maximum or minimum speed at which vehicles are allowed to travel on a particular road. This sign helps regulate traffic flow, promote safety, and prevent accidents by ensuring drivers do not exceed speeds that could be dangerous for road conditions or other drivers. Speed limit signs are typically marked with a number indicating the speed in miles per hour (mph) or kilometers per hour (km/h). Drivers must follow the speed limit to avoid fines or accidents and maintain safe driving conditions for everyone on the road.
