By which rule of thumb can you determine the braking distance in metres from speed when braking normally?

The braking distance in meters can be determined using the formula: (Speed in km/h / 10) x (Speed in km/h / 10). This means you take the speed in kilometers per hour, divide it by 10 to convert it to a more manageable figure, and then square that result to find the braking distance in meters. This formula is derived from the physics of motion and the relationship between speed and stopping distance, which is especially important in German traffic law to ensure safety on the roads.

Understanding this helps drivers maintain safe distances and react appropriately according to their speed, contributing to overall traffic safety. When determining braking distances, it is crucial to consider both the speed and the specific braking conditions.
