Theory test
You increase your speed from 30 km/h to 90 km/h. How is the breaking distance affected?
First calculate how many times higher the speed is:
90 / 30 = 3 times the speed
“The braking distance [...] increases quadratically with increasing speed.” (Driving Licence Book, 19th Edition, page 120)
- 32 = 3*3 = 9

- The road conditions are as in the photo. Suddenly, an obstacle appears 40 metres down the road, which causes you to brake quickly. Approximately how long will your reaction distance be if your reaction time is 1 second and you are driving at 70 km/h?
