All drivers and riders shall keep to their left on the road, or street, where they meet; when passing those moving in the same direction, they shall do so on the right side. At street corners, or crossings, persons riding or driving shall not pass others travelling by similar means, and in the same direction. Persons driving around corners leading to the right shall make a wide turn, entering the street or road on the left side. Accordingly, those driving around corners leading to the left, shall make a short turn. At such time all shall drive slowly.
