  **第一項**  道路運送法第九条第一項に規定する一般乗合旅客自動車運送事業者による同法第五条第一項第三号に規定する路線定期運行の用に供する自動車その他の政令で定める自動車（以下この条において「路線バス等」という。）の優先通行帯であることが道路標識等により表示されている車両通行帯が設けられている道路においては、自動車（路線バス等を除く。以下この条において同じ。）は、路線バス等が後方から接近してきた場合に当該道路における交通の混雑のため当該車両通行帯から出ることができないこととなるときは、当該車両通行帯を通行してはならず、また、当該車両通行帯を通行している場合において、後方から路線バス等が接近してきたときは、その正常な運行に支障を及ぼさないように、すみやかに当該車両通行帯の外に出なければならない。ただし、この法律の他の規定により通行すべきこととされている道路の部分が当該車両通行帯であるとき、又は道路の状況その他の事情によりやむを得ないときは、この限りでない。

  On a road with a vehicle traffic lane indicated by road signs or markings to be a priority lane for motor vehicles that a provider of motor carrier services for ride-sharing by general passengers as prescribed in Article 9, paragraph (1) of the Road Transportation Act make available for scheduled transportation on fixed routes as prescribed in Article 5, paragraph (1), item (iii) of that Act or for any other motor vehicle as prescribed by Cabinet Order (hereinafter referred to in this Article as a "fixed-route bus or other such motor vehicle"), a motor vehicle (other than a fixed-route bus or other such motor vehicle; the same applies hereinafter in this Article) must not proceed down that lane if traffic congestion on the road would render it unable to move out of the lane in the event that a fixed-route bus or other such motor vehicle approached from behind; and if a fixed-route bus or other such motor vehicle approaches from behind when a motor vehicle is proceeding down such a lane, the motor vehicle must promptly move out of the lane so as not to obstruct its regular operation; provided, however, that this does not apply if a motor vehicle is required pursuant to other provisions of this Act to proceed down that lane or if a motor vehicle must proceed down that lane due to road conditions or other compelling circumstances.
