Question

DentroTest · Accepted Answer

According to the General Traffic Regulations, traffic lights showing an illuminated white stripe on a black circular background are intended mainly for trams and regular-service buses. However, the rules specify that they are also binding on the drivers of any other vehicle traveling in a lane specifically reserved for buses (bus lane). Therefore, a discretionary-transport bus is only required to obey these lights when it is driving in a bus lane; if it drives in the ordinary lanes of the roadway, it must follow the conventional circular traffic lights.
