Operation & SafetyQuestion 57 of 60
What is the effect of anti-lock braking systems (ABS) on air brake vehicles?
a.They shorten the vehicle's normal stopping distance dramatically
b.They replace the need for the parking brake
c.They help keep the wheels from locking up during hard braking so you can maintain steering control
d.They eliminate the need to check air pressure
Explanation
ABS helps prevent the wheels from locking during hard or emergency braking, which helps you keep control and steer. ABS does not necessarily shorten stopping distance or let you drive faster; it is a system to help you retain control. You still brake normally, and the ABS works only when needed.
