How long may a driver remain in the passing lane on the autobahn?

On the autobahn, drivers are expected to use the left lane for overtaking and should return to the right lane once they have safely passed another vehicle. There is no specific time limit for how long a driver can remain in the passing lane, but they must not linger unnecessarily and should yield to faster traffic. Failing to do so can result in fines or penalties. It's important for drivers to be mindful of other road users and maintain safe driving practices.
