Does this sign indicate the end of a road with right of way?

The sign visible in the recording is D-1 "priority road" placed together with the T-6a plate, which indicates the course of the priority road through the intersection (in this case, it turns left). This sign informs about the beginning or continuation of a priority road, not its end. The end of such a road would be indicated by the D-2 sign "end of priority road", crossed out with a black line.
