What is the right course of action?

When encountering this situation, the traffic rules dictate that you must prioritize the tram and the motorcycle.

1. Allowing the tram to pass is essential because trams have right of way at most intersections, especially when signals or signage indicate their priority.
2. Similarly, allowing the motorcycle to pass is crucial in this context. As both the tram and the motorcycle are in a position to move through the intersection, it's necessary to yield to both to ensure safety and compliance with traffic regulations.

Understanding these rules is vital to prevent accidents and to show respect for other road users' rights, especially in mixed traffic scenarios like this one.
