A speed limit is the maximum legal speed at which a vehicle can travel on a specific road or highway. It is set by local or national authorities to ensure safety for all road users, including drivers, passengers, pedestrians, and cyclists. Speed limits can vary based on the type of road, traffic conditions, and surrounding environment. Enforcement of speed limits is typically carried out by law enforcement agencies using tools like radar guns and speed cameras. Violating speed limits can result in fines, points on a driver's license, or other penalties. Adhering to speed limits helps reduce accidents and promotes safer driving conditions for everyone on the road.
