When faced with a circular sign with a blue background and a white arrow pointing to the right, what must drivers do?

Question

DentroTest · Accepted Answer

Circular signs with a blue background and white pictograms or arrows are mandatory signs (the R-400 series, for the mandatory direction). In particular, sign R-400d tells drivers that they are strictly required to follow the direction indicated by the arrow, which in this case is the right turn at the intersection. It must not be confused with a prohibition sign (which would have a red border and a white background) or with a recommendation or information sign (which usually appears on square or rectangular panels).
