Where may you park here?

You answered correctly. In this situation, you are allowed to park on both the left and right-hand hard shoulders. This is indicated by the blue parking direction sign on the right, which shows arrows pointing to both sides. In Germany, if parking is permitted on both shoulders, you can choose either side as long as you do not endanger or obstruct traffic. If only one side was allowed, the sign would indicate that direction only. Always check for local signs and rules before parking.
