What will happen if, while braking on a motorcycle, the anti-lock braking system is initiated (ABS)?

Correct answer
B. This will help me to bypass obstacles without releasing the brake.
Explanation
In the photo you can see the ABS warning light - red letters in a circle with brackets. If the anti-lock braking system comes into action while you are braking on a motorcycle, it will let you go around obstacles without releasing the brake - answer B.
ABS measures the rotation of the wheels, and when a wheel starts to lock, it reduces the pressure in the brake for a fraction of a second and then increases it again - many times per second. The wheel keeps rolling all the time, so it keeps its side grip: you can turn and go around an obstacle without releasing the brake, and the motorcycle does not skid (so answer C is the opposite of the truth). Answer A is a popular myth - ABS does not shorten the braking distance in all conditions; on loose gravel, snow or deep sand a locked wheel pushes a ridge of material in front of it and brakes in a shorter distance than a rolling one, and ABS then makes the distance longer. The main advantage of ABS is stability and steering control. The Road Traffic Act requires you to brake without causing danger; with ABS, in an emergency you brake hard, with both hands, feeling the lever pulse, and you do not ease the pressure until you have passed the danger.
