Are you obliged to yield the right of way to vehicles approaching from the left at the nearest junction?

In the video you are driving along a road through a village and approaching a junction; on the right there is sign A-7 "give way" with plate T-6c showing that the priority road runs across your road. At the nearest junction you must give way to vehicles approaching from the left. The answer is: yes.

The Regulation on road signs and signals states that sign A-7 "give way" warns of a junction with a priority road, and the Road Traffic Act requires a driver approaching a junction to give way to vehicles travelling on the priority road, no matter which direction they are coming from - from the left and from the right. The right-hand rule, under which you give way only to vehicles from the right, applies only at uncontrolled junctions of equal roads, without signs. Beyond sign A-7 you slow down and, if necessary, stop, look left, right and left again, because a vehicle from the left is coming in the lane nearer to you, and you drive onto the junction only when you will not force anyone to brake. You recognise the A-7 triangle by its point facing down; unlike B-20, it does not require you to stop if the road is clear. At country junctions with limited visibility, however, you often have to stop to be able to see the intersecting road at all.

Legal basis: § 5 para. 5 of the Regulation on road signs and signals; Art. 25 para. 1 and Art. 2 point 23 of the Road Traffic Act (Prawo o ruchu drogowym)
