A limited-access highway is a type of road that does not allow certain things. It does not allow vehicles to enter or exit the road whenever they want. This means that cars, buses, bicycles, and even people on foot cannot get onto the highway unless there is an access point. Access points are usually marked by signs and can be seen from the side of the road. The limited-access highway is designed this way for safety, as it reduces the chances of a car crash or other type of accident. It also makes it easier for cars to travel longer distances without having to worry about people walking, running, or cycling in the way.
