Show the correct answer
Correct answer
B. Simultaneously pressing the brake and clutch pedals as strong as possible.
Explanation
The question is about the way of braking a lorry with ABS that stops the vehicle most quickly. It is pressing the brake pedal as hard as possible and pressing the clutch pedal at the same time - the answer is B.
The Road Traffic Act requires a driver to brake in a way that does not create danger, and with a sudden obstacle every metre counts. With ABS you brake in an emergency with one strong movement: you press the brake pedal all the way down and hold it, and you press the clutch at the same time so that the engine does not stall and jerk the vehicle. Then ABS itself controls the braking force on each wheel so that none of them locks. Pumping the brake (answer A) is the method for vehicles without ABS - with ABS it only makes the braking distance longer, because you keep taking your foot off the brake. Pressing the pedal gradually (answer C) also wastes valuable metres at the start of braking.
