In which direction is a passenger car allowed to drive?

Explication

The blue lane panel couples the right-pointing arrow with a bus symbol, so that movement is reserved for route vehicles and is closed to cars. For a sedan the remaining permitted movements are straight ahead and to the left, and a permitted left turn also allows turning to the opposite direction. Claiming every direction ignores the bus-only right turn, and dropping the straight movement narrows the permission without any ground.
