What is the right course of action?

In this scenario, it's important to understand the right of way rules as they pertain to the vehicles involved.

1. **Trams**: In Germany, trams often have priority over other vehicles, particularly at intersections. If you encounter a tram stop, and a tram is either approaching or just departed, you may need to yield to it.

2. **Red Car**: The red car may also indicate that it has the right of way, especially if it is already approaching when you are preparing to turn.

3. **First to Proceed**: If you are the first in the intersection without any other vehicles that have the right of way, you may proceed.

Considering these elements, a complete understanding is essential. You must give way to the tram and possibly to the red car, depending on the specific situation. This ensures safety for all road users and adherence to traffic regulations. Always assess the environment and prioritize the right of way accordingly. Understanding these principles will help navigate similar situations in real-life driving scenarios.
