Notwithstanding paragraph (2) and the preceding paragraph, to make a right turn on a road for which road signs or markings designate that, for a right turn of a general motorized bicycle at an intersection where traffic control is carried out, the bicycle must proceed along the side edge of the intersection, and on any other road with three or more vehicle traffic lanes on the left side of the road (or on the road itself, if it is a one-way street) (hereinafter referred to in this paragraph as a "multi-lane road") (but only when turning right at an intersection where traffic control is carried out), the driver of a general motorized bicycle must bring it as close as possible to the left edge of the road beforehand, and drive at reduced speed along the side edge of the intersection; provided, however, that this does not apply when road signs or markings designate, on a multi-lane road, that a general motorized bicycle must move beforehand towards the center or the right edge of the road for a right turn at an intersection where traffic control is carried out.
一般原動機付自転車は、第二項及び前項の規定にかかわらず、道路標識等により交通整理の行われている交差点における一般原動機付自転車の右折につき交差点の側端に沿つて通行すべきことが指定されている道路及び道路の左側部分（一方通行となつている道路にあつては、道路）に車両通行帯が三以上設けられているその他の道路（以下この項において「多通行帯道路」という。）において右折するとき（交通整理の行われている交差点において右折する場合に限る。）は、あらかじめその前からできる限り道路の左側端に寄り、かつ、交差点の側端に沿つて徐行しなければならない。ただし、多通行帯道路において、交通整理の行われている交差点における一般原動機付自転車の右折につきあらかじめ道路の中央又は右側端に寄るべきことが道路標識等により指定されているときは、この限りでない。
When the driver of a vehicle uses a hand or turn signal to indicate the intention to move towards the left edge, center, or right edge of the road pursuant to the preceding paragraphs before turning left or right on a road, the driver of a vehicles behind that vehicle must not obstruct the change of course unless avoiding this would make that driver have to suddenly change speed or direction.
