Is it allowed to stopover at the entry to the gate?

In the video you are driving along a housing estate street with detached houses; on the right, cars are parked by the kerb, and between them you can see the entrance to a property gate. Parking at this entrance is not allowed. The answer is: no.

The Road Traffic Act prohibits parking in a place that obstructs entry or exit, in particular to and from a gate, garage, car park or parking bay. A car left at an entrance blocks the residents and may be towed away at the owner's expense. You park so that the whole entrance stays clear, and if you have to park right next to it, you leave space for the manoeuvre of a vehicle coming out.

Legal basis: Art. 49 para. 2 point 1 of the Road Traffic Act (Prawo o ruchu drogowym)
