When are you not allowed to park on the right-hand lane?

Your selection of all three options is correct. In Germany, you are not allowed to park on the right-hand lane under the following circumstances:

1. If there is a paved hard shoulder, parking on the right-hand lane is prohibited to ensure safety for emergencies and traffic flow.
2. If there are rails integrated into the road lane, this is designed to direct traffic and prevent parking that could obstruct movement.
3. If there is a designated parking lane to the right, parking is restricted to that designated area, maintaining order and ensuring that traffic can move without interference.

Selecting all three options is important as they reflect key regulations aimed at maintaining safety and efficiency on the roads. This understanding helps drivers navigate safely and legally when dealing with road markings and signs.
