If you must use a truck escape (runaway) ramp, what should you expect and do?
- A.Aim for the ramp only if you can exit it at speed
- B.Avoid the ramp because it will always roll the vehicle
- C.Steer into the ramp as directed and let its deep material or upgrade slow the vehicle, using it rather than risking an uncontrolled descent
- D.Use the ramp as a shortcut parking area
Correct answer
C. Steer into the ramp as directed and let its deep material or upgrade slow the vehicle, using it rather than risking an uncontrolled descent
Why
Escape ramps are built to absorb the energy of a vehicle whose brakes cannot hold it on the grade. Using one may damage the vehicle, but it is designed to stop the descent before speed causes a far worse crash.
