• the row next to the curb or shoulder, those who want to change direction to the right;
• the row next to the axis of the road or next to the separation marking of the directions, those who want to change direction to the left. When traffic takes place on one-way roads, the drivers of vehicles who intend to turn left are obliged to occupy the row next to the curb or the shoulder on the left side;
• either of the rows, those who want to go straight ahead.
