What is the main safety purpose of knowing escape ramp locations on your route?

Explanation:
Knowing escape ramp locations is crucial because they provide a safe, engineered way to stop a heavy vehicle that has lost braking control on a downhill grade. Escape ramps are designed to dissipate the truck’s kinetic energy using materials like sand or gravel and a longer, steeper approach, allowing a controlled deceleration and stop without a high-speed crash. On long downgrades, brake fade or brake failure can lead to a runaway, and the ramp offers a last-resort option to prevent a serious crash. This is their sole safety purpose—far from improving fuel economy or serving as a routine stop.
