Vehicles will drive through the intersection in the following order:

Explication

The bus's path does not conflict with the shown trajectories, so it can clear the intersection first without crossing them. The tram continues straight on its rails while the motorcycle turns right without crossing those rails, allowing them to move together; the truck's wide curve is a U-turn through the junction and must wait for all three to clear before going last. Putting the truck earlier would make its U-turn cut across traffic it must yield to.
