When you approach a crossing marked in this manner, should you expect limited visibility?

In the photo you are approaching a level crossing; by the tracks there are a St Andrew's cross G-3 and sign B-20 "STOP", and above them a traffic mirror. When approaching a level crossing marked like this, you can expect limited visibility. The answer is: yes.

The Regulation on road signs and signals states that sign B-20 "STOP" means no entry without stopping, applied accordingly before tracks for rail vehicles, and the St Andrew's cross marks the place to stop because of train traffic at a level crossing without barriers. The set of signs itself tells you about visibility: B-20 is placed before a level crossing when the tracks cannot be seen from the road over a sufficient distance, and a traffic mirror is installed precisely so that the driver can see the section of track hidden by bushes, buildings or a bend. The Road Traffic Act requires you to exercise particular caution when approaching a level crossing and, before entering the tracks, to make sure that no rail vehicle is approaching - here this means stopping before the tracks, looking in the mirror and in both directions along the tracks, and if necessary opening the window to hear a train.

Legal basis: Art. 28 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym); § 21 para. 1, 2 and 4 and § 78 para. 5 of the Regulation on road signs and signals
