About Special lights: tram/bus, level crossing, bridge and lane: which statement is WRONG?
A white flashing light at a level crossing means exactly the opposite: no train is approaching, you may proceed.
A red cross means the lane may NOT be used, full stop.
Tram/bus lights ALSO apply to drivers of other vehicles lawfully using a bus lane or bus strip the light relates to.
At pedestrian lights, a flashing green means pedestrians may no longer start to cross.
Explanation
trap: flashing as a stop signal. Flashing green in fact means crossing is still allowed; it only warns that the red light will appear soon. Only red means you may no longer start
