Why this is the answer
The correct answer in the official bank: Drive to the right Turn before the sign.
A round blue sign is a mandatory sign that must be obeyed. A straight horizontal arrow pointing right means you must turn right before the sign, at the junction or spot in front of it. A bent arrow that goes up and then turns right means turning after the sign. Winding roads and double bends are shown by triangular warning signs, not blue circles.
