When driving a bus in a reserved lane and reaching an intersection regulated by a traffic light with an illuminated horizontal white stripe, what must you do if you intend to continue straight ahead?

AMake a mandatory turn to the right or to the left, since the sign prohibits only continuing straight ahead.

BContinue without stopping, since it is an indication that affects only trams.

CStop the vehicle, since that sign prohibits passage with the same effect as a steady red light.
