Where should you stop your vehicle when you are obliged to stop before a railway crossing?

1. In the place with the best field of view, without disturbing train traffic.
2. After the stop line, eight meters before the proximate rail.
3. Correct answer: Before the stop line. If there is no stop line – before the barrier.. If there is no barrier – at least four meters before the nearest rail.
4. Before the barrier. If there is no barrier – six meters before the nearest rail.

WhyStop before the stop line; if there is none, before the barrier; if there is no barrier either, at least 4 m from the nearest rail. The other numbers are made up.
