In Austrian vehicle safety and driving technique, what physical sensation does the driver experience through the brake pedal when ABS activates?
Answer and explanation
Correct answer: A. Rapid pulsing or vibration of the pedal accompanied by clicking noises
- Step 1: During ABS regulation, hydraulic valves pulse pressure rapidly (up to dozens of times per second), producing noticeable pedal chatter; drivers must keep pressing hard. Answer: Rapid pulsing or vibration of the pedal accompanied by clicking noises. Why not the others: The pedal sinks to the floor and loses all hydraulic resistance, The pedal locks rock-hard and cannot be pressed down any further and The pedal springs upwards and pushes the driver's foot off do not reflect Austrian technical safety guidelines.
