What should you do now?

Your answer is correct because after passing the "End of all temporary restrictions" sign, you must continue to comply with the "Rechtsfahrgebot," which requires you to drive as far to the right as possible when it is safe. This means you should not stay unnecessarily in the middle or left lanes once overtaking is complete. Braking is not necessary unless traffic conditions require it, and moving into the left-hand lane without a need to overtake would be against the rule. Driving on the right helps traffic flow smoothly and safely on German roads, especially on multi-lane highways.
