Which of these makes your braking distance longer?
Answer and explanation
Correct answer: C. Wet roads and worn tyres
- Step 1: Braking distance depends on grip, the vehicle's condition, the road and the speed. Step 2. Poor tyres and slippery surfaces reduce grip, so braking takes longer. Answer: Wet roads and worn tyres. Why not the others: Quick reactions affect thinking distance, and dry roads with good brakes shorten braking.
