You are travelling at 50 km/h and brake normally. What is the braking distance according to the rule of thumb?

You answered correctly. In Germany, the rule of thumb for calculating the braking distance at normal braking is: (speed in km/h divided by 10) times itself. At 50 km/h, that means 5 × 5 = 25 meters. This quick calculation helps drivers estimate how far their car needs to stop in normal conditions and increases your safety margin. Remember, in wet or slippery conditions, the actual stopping distance will be longer.
