What is aquaplaning?
Answer and explanation
Correct answer: A. Tyres lifted off the road by a film of water
- Step 1: A wedge of water can lift the tyres off the road. Step 2. Ease off the accelerator and do not brake hard. Answer: Tyres lifted off the road by a film of water. Why not the others: The engine drowning after driving through a flood: a flooded engine is a separate fault from tyres losing contact with the road. Brakes sticking in wet weather: brake seizure is a mechanical fault with no link to water on the road. A slow tyre puncture in the rain: a puncture is air loss, not water lifting the tyre.
