Why are buses and trucks equipped with antilock brakes (ABS)?
Correct answer: To keep them from skidding when the driver brakes suddenly.
Answer options
- ATo keep them from skidding when the driver brakes suddenly Correct
- BTo keep them from skidding when the driver turns too sharply
- CTo always shorten the distance needed to stop
Why
ABS senses when a wheel is about to lock during sudden, hard braking and adjusts brake pressure so the wheels keep turning and the vehicle does not skid. It will not necessarily shorten the stop, and it does nothing to prevent a skid caused by turning too sharply.
