In this situation, does the flashing yellow light allow you to drive beyond the traffic lights without stopping?

In the situation shown, the signal is flashing yellow, which according to § 98 para. 6 of the Regulation on Road Signs and Signals warns of danger and commands extreme caution, but does not prohibit entry or mandate an absolute stop. In such a case, the vertical signs apply, and the visible sign D-1 "priority road" confirms your right of way. Thus, if road conditions permit, you may pass through the intersection without stopping.
