When driving straight on through this intersection, do you have priority over the vehicle on the right?

In the video you are driving along a street among houses and trees behind a red car; on the right there is sign D-1 "priority road", under it D-6 with plate T-27, and a white car is coming out of an intersecting road on the right. When driving straight on through this junction, you have right of way over the vehicle on the right. The answer is: yes.

The Regulation on road signs and signals states that sign D-1 "priority road" marks the start or continuation of a priority road; a driver coming out of the intersecting road sees sign A-7 or B-20 and must give way to you. The right-hand rule, which would give right of way to the white car, applies only at uncontrolled junctions of equal roads - the yellow diamond cancels it. However, the Road Traffic Act requires you to exercise particular caution when approaching a junction and a pedestrian crossing, which according to plate T-27 is used especially often by children. You watch the white car and do not force your way through if its driver has not noticed the sign - right of way does not protect you from a collision, and the principle of limited trust tells you to allow for other people's mistakes.

Legal basis: § 43 para. 1 and § 47 para. 5 of the Regulation on road signs and signals; Art. 25 para. 1, Art. 26 para. 1 and Art. 4 of the Road Traffic Act (Prawo o ruchu drogowym)
