What is the rule of thumb when calculating the braking distance for evasive braking on a dry, even and asphalted roadway?

The rule of thumb for calculating braking distance during evasive braking is important for ensuring road safety. The correct combination involves using a formula that takes into account both the speed of the vehicle and a multiplier based on the conditions of the road. Specifically, the formula helps estimate the stopping distance of a vehicle given its speed in kilometers per hour.

In this context, the braking distance increases with speed, which is why the first part of the formula uses the speed divided by 10. This value is then multiplied by itself (to represent the kinetic energy of the vehicle), and the result is divided by 2 to account for the deceleration when braking.

Selecting the correct answer helps drivers understand how distance will increase under specific conditions, which is essential for maintaining safe distances from other vehicles, especially in emergency situations. Understanding these calculations can help prevent accidents and promote safer driving behaviors in accordance with German traffic regulations.
