You increase your speed from 50 km/h to 100 km/h. How does the reaction distance change in accordance with the rule of thumb?

When you increase your speed from 50 km/h to 100 km/h, the reaction distance, which is the distance your vehicle travels while you react to a hazard, significantly increases. According to the rule of thumb in German traffic regulations, doubling your speed quadruples your reaction distance. This means if your reaction distance at 50 km/h is 15 meters, it becomes approximately 60 meters at 100 km/h, demonstrating a considerable increase in stopping distance and highlighting the importance of driving at appropriate speeds for conditions. Understanding this concept is essential for safe driving as it emphasizes the need for adequate stopping distance based on your speed.
