What should you do now?

In this scenario, you should only pass the construction site and move into the oncoming lane if you are sure that no oncoming vehicles are coming. German traffic law requires you to yield to oncoming traffic when your lane is blocked (for example, by roadworks), and you may only use the opposite lane to pass the obstruction if it is clear. That is why selecting the answer about proceeding "if it is clear that there is no oncoming traffic" is correct.

Answers suggesting that oncoming traffic must already be waiting, or that you do not need to consider oncoming traffic, are incorrect. The right of way goes to vehicles approaching unobstructed in their own lane. Always check carefully for oncoming vehicles before entering the opposite lane, and only proceed when it is safe and clear. This rule helps prevent head-on collisions and ensures smooth, safe traffic flow at temporary or partial obstructions.
