Are you allowed to turn left to the parking space in the place marked in such a way?

The car park is on the left side of the road, but at its entrance the roadway is divided by a double solid line. Turning left would mean crossing this line, which the rules prohibit. So you cannot turn into the car park at this place.

Sign P-4 "double solid line" separates lanes for opposite directions and means that you must not cross it or drive onto it. On the earlier section the line was broken and you were allowed to cross it, but exactly level with the car park the road authority painted a double solid line. So you drive on and look for a place where the line is broken again or where you are allowed to make a U-turn.
