In the presented situation, are you approaching a level crossing with barriers?

In the video you are driving along a road through a forest behind a silver car, and on the right you pass warning sign A-9 with a fence symbol, with countdown marker post G-1a with three bars below it. You are approaching a level crossing with barriers - this is exactly what the sign with the fence tells you. The answer is: yes.

The Regulation on road signs and signals states that sign A-9 "level crossing with barriers" warns of a level crossing equipped with barriers or half-barriers, and countdown marker posts G-1a, G-1b and G-1c with three, two and one bar inform you that you are approaching the crossing; the post with three bars stands at the warning sign, and the next ones at two thirds and one third of the distance to the tracks. A crossing without barriers is marked by a different sign - A-10 with a locomotive symbol. The Road Traffic Act requires you to exercise particular caution when approaching a crossing and to make sure that no rail vehicle is approaching, and it also prohibits entering the crossing when the barriers are being lowered, are down or are being raised. From marker post G-1a you slow down, do not start overtaking, and look out for the barriers and the traffic lights.

Legal basis: § 6 para. 1 and 2 and § 78 para. 1 and 2 of the Regulation on road signs and signals; Art. 28 para. 1 and para. 3 point 1 of the Road Traffic Act (Prawo o ruchu drogowym)
