A speed limit is the maximum legal speed at which vehicles can travel on a specific road or area. It is set by local or national authorities to ensure safety for all road users, including drivers, pedestrians, and cyclists. Speed limits can vary based on the type of road, such as highways, residential areas, or school zones. Enforcement of speed limits is important to reduce accidents and improve traffic flow. Drivers who exceed the speed limit may face fines or penalties. Signs indicating the speed limit are placed along roads to inform drivers of the current limit, helping to maintain safe driving conditions.
