In what orientation must a flashing illuminated white stripe be on a bus-only traffic light to be equivalent to a conventional steady yellow light?

Question

DentroTest · Accepted Answer

Annex I of the General Traffic Regulations (section 4.4) regulates the traffic lights reserved for trams and regular-service buses, with an illuminated white stripe on a black circular background. The horizontal stripe prohibits passage under the same conditions as a non-flashing red light; the vertical one allows passage straight ahead; the oblique one, turning toward the side it indicates. When the white stripe, vertical or oblique, is lit flashing, the vehicles it affects must stop under the same conditions as if it were a steady yellow light. For that reason, the vertical or oblique position is the one equivalent to yellow. The horizontal position is equivalent to red, and the answer that admits the horizontal or the vertical fails precisely because it includes the horizontal.
