Question 78 of 160

You feel the bus hydroplaning slightly in heavy rain despite having ABS. What does this tell you?

Pick an answer

ABS is what caused the hydroplaning in the first place
Hydroplaning is impossible with ABS, so something else must be wrong with the tires or the road surface
ABS cannot restore traction lost when the tires ride on top of water, it only helps once the wheels can grip again
ABS has failed and needs immediate replacement

Correct!

Not quite. The correct answer is highlighted.

Correct answer to question 78 (School Bus): ABS cannot restore traction lost when the tires ride on top of water, it only helps once the wheels can grip again

Why

ABS manages wheel lockup, but it can't create traction that isn't there when tires are riding on a layer of water; it only starts helping again once the tires regain contact with the road.
