In this situation, are you approaching a multi-track level crossing?

In the video you are driving in fog on a road through fields and approaching a level crossing without barriers; before the tracks there are posts, traffic lights and a red-and-white double St Andrew's cross - sign G-4. The double cross means that you are approaching a multi-track level crossing. The answer is: yes.

The Regulation on road signs and signals provides that signs G-3 "St Andrew's cross before a single-track level crossing" and G-4 "St Andrew's cross before a multi-track level crossing" mark the place to stop because of train traffic at a level crossing without barriers, and inform you that there is one track or more than one track at the crossing, respectively. With several tracks, a train that has just passed may hide a second one coming from the opposite direction, which is why the Road Traffic Act requires you to make sure before entering that no rail vehicle is approaching - you look both ways along all the tracks, and in fog you slow down even more.

Legal basis: § 78 para. 5 of the Regulation on road signs and signals; Art. 28 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
