The correct course of action when a driver in the passing lane of the autobahn sees a vehicle approaching from behind with flashing headlights is to change lanes immediately. This action is a conventional signal indicating that the following vehicle intends to pass. Maintaining speed in this scenario would not prioritize the safer and more efficient flow of traffic, which is crucial on high-speed roads such as the autobahn.

In such situations, those in the passing lane should be attentive to the behavior of the vehicles behind them and make a conscious effort to yield to faster traffic. This helps ensure that the left lane remains clear for overtaking, allowing for safer driving conditions for all motorists on the road. It's vital for drivers to be aware of the custom and rules surrounding highway driving, particularly in regions like Germany where specific practices, such as yielding to vehicles with flashing lights, are standard.
