You are travelling at 40 km/h. The braking distance for evasive braking is approximately 8 metres. How long is the braking distance at 50 km/h given otherwise the same conditions?

When traveling at higher speeds, the braking distance increases significantly due to the physics of motion and the need for more time to slow down. The relationship between speed and braking distance is not linear; rather, it increases with the square of the speed.

In this scenario, if you know that the braking distance at 40 km/h is approximately 8 meters, you can calculate the braking distance at 50 km/h by recognizing that as speed increases, the distance required to come to a stop also increases. The formula for braking distance is often approximated by a factor of the square of the speed increase.

Therefore, at 50 km/h, the braking distance will be greater than at 40 km/h, leading to distances of around 11 to 12.5 meters depending on the factors like road conditions and vehicle type. By understanding this, you can appreciate the importance of maintaining appropriate speeds for the conditions and knowing that faster speeds require longer stopping distances, which is critical for safety in traffic according to German traffic regulations.
