You approach a roundabout with a tram line crossing the exit. Which principle is best?

1. Give free passage to the tram when required, but follow roundabout signs and markings for the exact priority situation
2. A tram always has to yield to a motorcycle inside any roundabout exit
3. A motorcycle always has to stop for trams even when signs give the tram give-way on entry
4. Ignore tram tracks if the motorcycle can accelerate across them
