A light signal with no level crossing sign is positioned before a level crossing, and in front of a junction with a road to the right. The red light is illuminated. Where must you wait?

In the scenario with a red light positioned before a level crossing, it indicates that you must stop. As per German traffic rules, when a red light is illuminated, you have to wait at the stop line if there is one available. If there is no stop line, you should stop in front of the traffic light.

This is crucial for safety at level crossings, as approaching trains could be present, and stopping at the correct position helps prevent accidents. It's important to recognize and adhere to traffic signals to maintain safe driving practices.
