Speed limits are rules set by local governments to control how fast vehicles can travel on roads. These limits help ensure safety for everyone, including drivers, passengers, and pedestrians. For example, a school zone might have a lower speed limit to protect children walking to and from school. Different types of roads have different speed limits. Highways usually allow faster speeds, while residential areas often have lower limits to reduce the risk of accidents. Drivers must pay attention to speed limit signs to avoid fines and keep the roads safe for all users.
