What is the primary purpose of truck escape ramps on long grades?

• A. To slow traffic
• B. To avoid damage to vehicles
• C. To reduce fuel consumption
• D. To provide emergency parking

Answer: (B)

Escape ramps are safety devices on long grades designed for braking emergencies when a heavy truck’s brakes fail or overheat on a descent. They provide a controlled area, often with materials that slow and stop the vehicle, so the truck can come to a halt without crashing into traffic or going off the road. The main purpose is to prevent damage to the truck, other vehicles, and roadside property by stopping the runaway vehicle safely. They’re not intended to slow regular traffic, serve as parking spaces, or improve fuel efficiency.
