At what point should a driver whose brakes are overheating and fading on a grade decide to use the runaway ramp?
- A.Only after the service brakes have failed entirely and speed is at its peak
- B.Before speed builds beyond control, while the truck can still be steered into the ramp entry
- C.After passing the ramp to see if the road levels out
- D.Never, because using a ramp counts against the driver
Correct answer
B. Before speed builds beyond control, while the truck can still be steered into the ramp entry
Why
A ramp used early, at a manageable speed, is a controlled stop with gravel damage at worst. Waiting until the truck is running away at full speed turns the same ramp into a crash, so the decision belongs at the first clear signs of fade.
