Yes: Correct
U-turns are generally allowed unless explicitly prohibited by road signs, markings, or traffic rules. If there are no signs indicating a restriction on U-turns and the road conditions permit it (e.g., sufficient visibility, no traffic congestion, and safety for other road users), then making a U-turn is permissible. There are some places where U-turns are prohibited: at level crossings, in tunnels, underpasses and sections of road affected by the “Tunnel” sign (S-5), as well as on motorways and dual carriageways except in places designated for this purpose, and, in general, on all sections of road where overtaking is prohibited, unless U-turns are expressly authorized.
No: This would be incorrect unless there are clear prohibitions, such as a “No U-turn” sign, double continuous lines, or specific local traffic laws that restrict U-turns on that stretch of road.
