You are driving at the recommended speed on the motorway and want to leave it at the next exit. What should you do?

The combination of choices you selected is correct because it follows the essential principles of safe driving when exiting a motorway according to German traffic rules.

1. Ceasing overtaking maneuvers in good time is crucial as it ensures you do not put yourself and other drivers at risk while preparing to exit. This is important for maintaining safety and preventing potential accidents.

2. Significantly reducing your speed on the exit lane is necessary because exit lanes are typically designed for slower speeds than the main motorway. This helps in safely navigating the curve of the exit and merging into the next road.

Both of these actions are aimed at ensuring a smooth and safe transition from the motorway, which is required by German traffic regulations to promote road safety. It is important to make the necessary adjustments to your speed and maneuvers to accommodate for the different driving conditions outside the motorway.
