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?

In the context of German traffic rules, reaction distance increases significantly with speed. The rule of thumb states that when you double your speed, your reaction distance increases by a factor of four.

1. When you travel at 50 km/h, the typical reaction distance is around 15 meters. At 100 km/h, the reaction distance becomes approximately 60 meters, not 30 meters or 100 meters.
2. Understanding this principle is critical for safe driving, as it emphasizes the need for longer stopping distances at higher speeds, which helps prevent accidents.

Selecting the correct combination is essential because it highlights the exponential relationship between speed and stopping distance in traffic scenarios.
