In the situation that you see here, can you enter the railway crossing?

In the photo you are approaching a level crossing with half-barriers; the traffic lights at the crossing show a red light, and the half-barrier on the right is being lowered. In this situation you are not allowed to enter the crossing. The answer is: no.

The Road Traffic Act prohibits entering the crossing if the lowering of the barriers or half-barriers has started or their raising has not been completed, and also driving around lowered barriers; the Regulation on road signs and signals specifies that flashing red signals mean a ban on entering beyond the device that shows them. The half-barrier closes only your lane, but this is not an invitation to drive around it on the left - driving around it like this is one of the most dangerous petty offences. You stop before the traffic lights and wait until the half-barriers go up and the lights go out.

Legal basis: Art. 28 para. 1 and para. 3 point 1 of the Road Traffic Act (Prawo o ruchu drogowym); § 98 para. 5 of the Regulation on road signs and signals
