About Level crossing: markers, the Saint Andrew's cross, and the red flashing light: which statement is correct?
A level crossing without barriers (recognisable by the locomotive-symbol sign) is less dangerous, so you may drive over it faster.
You must stop as soon as the crossing lights start flashing red and the alarm bells start ringing; the barriers only lower a few seconds later.
Overtaking just before or on a level crossing is legally prohibited, just like at a pedestrian crossing (zebra crossing).
Just before a level crossing you always wait until after the crossing to overtake a cyclist, even with a clear view and enough room.
