You intend to make a U-turn at the junction while the vehicle is entering the junction. Are you obliged to yield the right of way?

In the video, you are entering a small roundabout in a housing estate, marked only with sign C-12 "roundabout", without sign A-7; you intend to make a U-turn on it. On such a roundabout the right-hand rule applies, so while driving around the island you must give way to a vehicle entering the roundabout from your right. The answer is: yes.

The Regulation on road signs and signals states that sign C-12 means that at the junction traffic moves around the island in the direction shown on the sign, and the Road Traffic Act requires you to give way to a vehicle coming from the right. Only sign A-7 before the entry reverses this rule and gives right of way to those driving on the roundabout. While making the U-turn, you watch every entry on the right and, if necessary, stop on the roundabout.

Legal basis: § 36 para. 1 of the Regulation on road signs and signals; Art. 25 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
