How must you act in a situation if you have stopped before a railway crossing at the prohibiting traffic-light signal, when the train has already passed but the light and sound signals have not yet turned off?

1. 1Continue travelling across the crossing in any case.
2. 2Continue travelling across the crossing only after making sure there is no approaching train.
3. 3Wait for the prohibiting traffic-light signal and the audible signal to switch off, and also make sure there is no approaching train, after which continue travelling.
