Speeding refers to driving a vehicle faster than the legal speed limit set for a particular road. It can be dangerous because it reduces the driver's ability to react to sudden changes, such as a pedestrian crossing or a car stopping unexpectedly. When drivers exceed the speed limit, they not only put themselves at risk but also endanger others on the road, including cyclists and motorcyclists. Law enforcement agencies often monitor speeding through the use of radar guns and speed cameras. If caught, drivers may face fines, points on their driving record, or even license suspension. It's important to obey speed limits to ensure safety for everyone on the road.
