What is the correct course of action on this one-way road?

Your answer to wait until the roadworks allow you to pass is correct because reversing or turning around on a one-way street is generally unsafe and often prohibited. On a one-way road with construction blocking the way, you must wait until the workers or officials indicate that it is safe to continue forward. This is to avoid conflicts with traffic and pedestrians, and to ensure safety.

In German traffic rules, you should never reverse on a one-way street unless absolutely necessary and with extreme caution, and turning around is not an option if it disrupts traffic or is not allowed. Waiting patiently and following instructions from road workers is the safest and legally correct action. This helps keep traffic orderly and prevents accidents.
