At night on the N36 near Vriezenveen you are driving 100 km/h. What is your reaction distance per the book's rule of thumb?
- ✓ 27.50 m
- 1 second
- Practically 0 m, since it's negligible
Correct answer: 27.50 m
Explanation
'1 second' is the reaction second (time); the reaction distance (metres) is ((100:2)+10%):2 = 27.50 m
Why learners get this wrong
- '1 second' is the reaction second (time); the reaction distance (metres) is ((100:2)+10%):2 = 27.50 m
- At 100 km/h the reaction distance is 27.50 m — a substantial part of your stopping distance, not something to ignore
