Travelling on a main road after a lengthy period of time of following behind, you are finally able to overtake a very slow-moving car. What should you do?

The selected answer is correct because it aligns with the principle of safely merging back into the lane after overtaking. According to German traffic regulations, after overtaking, it is crucial to ensure that you do not impede the vehicle you have just passed by returning to your lane too soon. This promotes safe driving practices and helps maintain a smooth flow of traffic.

Braking to call attention to the slow driver's speed or driving slowly to emphasize the impact of their driving style is not appropriate. It can create confusion and potentially lead to traffic disturbances. Always prioritize safety and courtesy when overtaking, ensuring adequate distance before returning to your lane. This underscores the importance of awareness and respect for other road users on the road.
