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

The rule of thumb for determining the distance a vehicle travels in one second based on its speed is to divide the speed in kilometers per hour by ten and then multiply by a factor. The most accurate approach combines options effectively.

For example, dividing by ten gives you the speed in meters per second. Multiplying that by three provides a rough estimate for stopping distance, while multiplying by five can give insight into reaction distance.

Understanding this calculation is crucial for safe driving, as it helps drivers anticipate stopping distances and improve reaction times, critical factors in road safety under German traffic regulations. Always consider both stopping and reaction distances when calculating travel distances based on speed.
