Is it forbidden to park the car immediately after the countdown post you see here?

In the photo, you are driving along a street towards a level crossing, before which there are signs B-20 "STOP" and G-3 "St Andrew's cross". On the right, you can see a countdown post with one stripe (G-1c) - the last of the three posts placed before a level crossing. The Road Traffic Act prohibits parking along the whole stretch from this post to the level crossing, on both sides of the road. The answer is: yes.

The Road Traffic Act prohibits parking before and after a level crossing, on both sides of the road, on the stretch from the level crossing to the countdown post with one stripe. The Regulation on road signs and signals explains that G-1 posts inform you that you are approaching a level crossing: the post with three stripes stands under the warning sign, the one with two stripes at 2/3, and the one with one stripe at 1/3 of the distance from the sign to the level crossing. A car parked there would block the view of the tracks and the signs, so if you want to stop for longer, do it before the post with one stripe or only after the level crossing, beyond a stretch of the same length.

Legal basis: Art. 49 para. 2 point 3 of the Road Traffic Act (Prawo o ruchu drogowym); § 78 para. 1 and 2 of the Regulation on road signs and signals
