What is the purpose of an escape ramp?

The purpose of an escape ramp is specifically designed to slow and stop vehicles that have lost their brakes. When a vehicle, typically a large truck or bus, experiences brake failure, it can travel at high speeds downhill, posing significant risks to the driver and others on the road. Escape ramps are strategically placed on steep grades to provide a safe area for these vehicles to reduce speed and come to a stop, thereby preventing accidents and potential injuries.

These ramps are equipped with materials such as sand, gravel, or tires, which help with the deceleration process. The design of an escape ramp allows it to be effective in emergencies, providing a crucial safety measure for drivers.

While other options relate to different aspects of road or vehicle management, they do not capture the primary and critical function of escape ramps in emergency braking scenarios.
