To make a right turn and exit the road, a driver must bring a vehicle (other than a specified small motorized bicycle or light road vehicle, or a trolleybus) as close as possible to the center of the road beforehand (or as close as possible to the right edge of the road, if the road is a one-way street) and drive at reduced speed.
Once the driver of a vehicle indicates the intention to make a left or right turn in order to exit the road and brings the vehicle towards the left edge, center, or right edge of the road pursuant to the preceding two paragraphs, the driver of a vehicle behind the turning vehicle must not obstruct the course of the turning vehicle unless avoiding this would make the driver have to suddenly change speed or direction.
