Question

In terms of impulse, what is the benefit of a “runaway truck ramp” on steep mountain roads?

Expert Solution

Step 1

Truck escape ramps are designated emergency areas where heavy-duty vehicles can be quickly slowed down in the case of brake failure using sand, gravel, and/or wire nets. The majority of these ramps resemble exit ramps from a highway leading to a dead end.

Gravel piled up to 48 inches deep is used on flat, unpaved runaway ramps to prevent runaway. There are steep runaway ramps with a long ascent. These use a gravity escape ramp (the part that is uphill) and an arrester bed made of gravel or sand to halt a runaway truck.
