You intend to turn left at this junction. Do you have priority over any vehicles that may emerge?

In the video you are driving on a country road towards a junction marked with sign D-1 with plate T-6a, on which the priority road turns right and a thin line goes off to the left. When you intend to turn left, you do not have right of way over all vehicles that may appear. The answer is: no.

The Regulation on road signs and signals states that plate T-6a under sign D-1 shows the actual route of the priority road through the junction. Since the thick line turns right, the priority road goes off to the right, and the road to the left, into which you want to turn, is a minor road. When turning left, you leave the priority road, so you must give way to vehicles driving on it - above all those approaching from the right, along the thick line; they will cross your path. So you cannot say that you have right of way "over all" vehicles. The Road Traffic Act also requires you to exercise particular caution when approaching a junction. A rule to remember: sign D-1 gives right of way only in the direction of the thick line; every turn off it means entering a minor road, where you give way to those who stay on the main road.
