In the presented situation, are you obliged only to turn right?

In the photo you are approaching a junction in a town; on the right there are signs C-8 "turn right or left", D-21 "hospital" and D-6, and opposite you can see sign B-2 "no entry". You do not have to turn only right - you may also turn left. The answer is: no.

The Regulation on road signs and signals states that sign C-8 requires the driver to drive in the direction shown by the arrows, that is right or left, and it applies at the nearest junction. Going straight on is also ruled out by sign B-2 on the street opposite. You choose the direction in good time, signal it with the indicator and, before turning, give way to pedestrians on the crossing.

Legal basis: § 35 para. 1 point 8 and para. 2 and § 17 para. 1 of the Regulation on road signs and signals
