What is the correct conduct?

In the scenario presented, the tram has priority over other vehicles, which is a key aspect of German traffic laws. When faced with a situation where a tram is approaching and you have the option to either let the tram pass or allow another vehicle (like the tractor) to turn, it's imperative to give way to the tram.

The correct conduct in this situation is to let the tram through. This is outlined in the German road traffic regulations, which stipulate that trams typically have priority over road vehicles on tram tracks. It's crucial to prioritize the tram as this helps maintain public transport flow and safety.

If the question had multiple answer choices, understanding and selecting the correct combination ensures that you're following traffic rules appropriately, promoting a safer environment for all road users.
