A driver's typical thinking distance is 12 metres. What is the typical overall stopping distance at that speed?
Answer and explanation
Correct answer: B. 36 metres
- Step 1: Thinking distance of 12 m matches 40 mph in the Highway Code table. Step 2. At 40 mph the braking distance is 24 m, so the overall distance is 12 + 24 = 36 m. Answer: 36 metres. Why not the others: 24 m is only the braking distance, 48 m is double the thinking distance, and 53 m belongs to 50 mph.
