You are driving at approximately 80 km/h on the autobahn. Which distance must you keep from the vehicle travelling in front?

On the autobahn and other roads outside built-up areas, the safe distance to the vehicle in front should be at least half your speed in meters. At 80 km/h, this means you must leave at least 40 meters, but the rule requires a minimum of 50 meters for higher speeds. Keeping this distance gives you enough time and space to react and stop safely in case the vehicle ahead brakes suddenly. This helps prevent rear-end collisions and is a key part of road safety on fast roads like the autobahn. So, choosing "at least 50 m" was correct for your speed.
