In this situation, are you allowed to drive, at the intersection, in the direction opposite to the direction shown on the mandatory traffic sign?

The C-12 'Roundabout' sign is a mandatory sign that indicates the required direction of travel at a junction. According to the arrows on the sign, traffic around the central island moves in a counter-clockwise direction. Driving in the opposite direction is strictly forbidden, as it would mean driving against the flow of traffic, which is extremely dangerous.
