What is the primary function of an escape ramp?

The primary function of an escape ramp is to reduce the speed of runaway vehicles, particularly large trucks or vehicles that have lost their brakes. These ramps are designed to safely divert vehicles off the main roadway when they are experiencing braking failures or other emergencies.

Escape ramps are typically built with materials that can slow down a vehicle, such as gravel or sand, and they are strategically placed on steep grades where the risk of runaway vehicles is higher. When a driver realizes they cannot maintain control, they can use the escape ramp to come to a stop, preventing potential accidents or collisions on the highway.

This function is crucial for enhancing road safety for everyone, as it provides a method for drivers to avoid dangerous situations caused by mechanical failures. Other choices, such as allowing vehicles to turn around, parking safely, or maintenance access, do not align with the essential purpose of escape ramps in emergency situations.
