What is the typical overall stopping distance at 30 mph on a dry road, according to the Highway Code?
Answer and explanation
Correct answer: C. 23 metres
- Step 1: Overall distance is thinking distance plus braking distance. Step 2. At 30 mph that is 9 m plus 14 m, giving 23 m. Answer: 23 metres. Why not the others: 12 m is the figure for 20 mph, 36 m is for 40 mph and 53 m is for 50 mph.
