What is the function of the ABS in a lorry?
Show the correct answer
Correct answer
C. It enables driving during emergency braking.
Explanation
The question is about the job of the ABS system in a lorry. It allows you to steer the vehicle during emergency braking - the answer is C.
The Road Traffic Act requires a vehicle to allow the driver to use the steering and braking devices easily and reliably. ABS makes sure that the wheels do not lock during hard braking: many times a second it lowers and raises the pressure in the brakes of the wheel that is starting to lock. A wheel that keeps rolling still responds to the steering wheel, so you can go around an obstacle, and the vehicle combination does not jackknife. It is not true that ABS always makes the braking distance shorter (answer A) - on loose gravel or snow it may even make it longer. Nor is it insensitive to the road surface (answer B), because it does not increase grip.
