By which rule of thumb can you determine from the speed the distance in metres a motor vehicle travels in one second?

To determine the distance a vehicle travels in one second based on its speed in km/h, you can use the formula: {Speed in km/h}/10. The result gives you the distance in meters for each second of travel.

However, for a more precise measurement, this distance can be adjusted based on kinematic principles. The combination involving multiplication by 3 accounts for the fact that this distance remains fairly constant under typical driving conditions. It's essential to understand these rules for better estimating stopping distances and reaction times on the road, which are critical for safe driving according to German traffic laws.

Knowing how to calculate this can enhance your awareness on the road and improve overall safety.
