What are you required to do when you notice the following traffic sign (in the picture) placed above your driving lane?

- Slow down before the level crossing, and if a train is approaching - stop.
- Correct answer: Do not enter this lane and do not continue driving in it.
- Slow down before the level crossing and pass the tracks without delay or interruption.
- Stop before the tracks until the train passes.
Why this is the answer
The correct answer in the official bank: Do not enter this lane and do not continue driving in it.
A red X placed above a lane means the lane is closed to traffic. You must not enter it, and anyone already driving in it must move carefully into an open lane. Although it looks like the X of a level crossing, this sign has nothing to do with a train.
