What should you do?
Stop at the stop line when the red lights flash and stay stopped until they go out, even if one train has passed.
How to recognise it
Yellow rectangular plates reading STOP nuair a lasann na soilse dearga and STOP When Red Lights Show.
Common confusion
Flashing red lights at a crossing mean stop just like a red traffic light; they are not an amber-style caution.
