You are driving at 80 km/h behind a motor vehicle. What is the minimum safe distance you must observe?

The correct answer for maintaining a safe distance when driving behind another vehicle at 80 km/h is a "distance of 2 seconds." This rule is based on German traffic regulations, which suggest that a safe following distance should allow for adequate reaction time in case the vehicle ahead suddenly brakes.

A following distance of 1 second may not provide enough time to react safely, especially in emergency situations. The option about the distance of 15 metres can also be misleading, as it varies depending on the speed of the vehicle. Thus, the best rule of thumb is to maintain a distance that allows for 2 seconds of travel time behind the vehicle in front of you.

This approach is essential for ensuring safety on the roads, reducing the risk of collisions, and promoting responsible driving behavior.
