What are exit ramps used for?

Exit ramps are specifically designed for vehicles to leave or exit from the highway safely. They provide a dedicated pathway that allows drivers to transition from high-speed highway travel to lower-speed local roads or access points, improving overall safety and traffic flow. This function is crucial, as it enables vehicles to decelerate and navigate away from fast-moving highway traffic, significantly reducing the risk of collisions.

The other options describe scenarios that are not appropriate for exit ramps. Entering the highway typically uses entry ramps, while parking or resting is not permitted on exit ramps, as they are designed solely for the purpose of exiting the highway.
