On receipt of a request as referred to in Article 21, paragraph (1) or Article 23, paragraph (2) of the Air Pollution Control Act (Act No. 97 of 1968), Article 17, paragraph (1) of the Noise Regulation Act (Act No. 98 of 1968), or Article 16, paragraph (1) of the Vibration Regulation Act (Act No. 64 of 1976), or on learning that a traffic nuisance has occurred and finding it to be necessary to do so, a public safety commission may carry out the administrative processes to prevent traffic nuisances over which it has authority pursuant to Article 4, paragraph (1). When doing so, the public safety commission may ask the prefectural governor or head of the relevant local government to provide materials relating to the traffic nuisance, if it finds this to be necessary.
If a public safety commission seeks to prohibit motor vehicles from entering onto a road based on Article 4, paragraph (1) using road signs or markings as referred to in Article 8, paragraph (1), and the prohibition is likely to have a significant effect on road traffic across a wide area, it must hear the opinions of the prefectural governor, the heads of the relevant local administrative organs, and the persons that Cabinet Order prescribes.
Before regulating traffic based on Article 4, paragraph (1) using road signs or markings as referred to in Article 2, paragraph (1), item (iii), item (iii)-4, item (iv), item (iv)-2, or item (vii), Article 4, paragraph (3), Article 8, paragraph (1), Article 13, paragraph (2), Article 17, paragraph (4), paragraph (5), item (v), or paragraph (6), Article 17-2, paragraph (1), Article 22, paragraph (1), Article 23, Article 34, paragraph (5), Article 49, paragraph (1), Article 63-4, paragraph (1), item (i), or Article 63-7, paragraph (2) (but only road signs or markings that Cabinet Office Order/Order of the Ministry of Land, Infrastructure, Transport and Tourism prescribes, if they are as referred to in Article 17, paragraph (6); and only road signs or markings showing a maximum speed limit exceeding that which Cabinet Order prescribes as referred to in Article 22, paragraph (1), if they are as referred to in that paragraph; the same applies hereinafter in this Article), a public safety commission (or the chief of a police station to whom authority has been delegated pursuant to Article 5, paragraph (1); the same applies hereinafter in this Article) must hear the opinion of the manager of the road on which the traffic would be so regulated (but only if it is a road as under the Road Act, for road signs or markings other than as referred to in Article 22, paragraph (1) and Article 63-4, paragraph (1), item (i)); provided, however, that this does not apply if traffic will be regulated using road signs or markings as prescribed in Article 8, paragraph (1) and urgent circumstances are found to compel the commission to do otherwise, in which case the commission is to notify the manager of its regulation of traffic promptly after doing so.
公安委員会（第五条第一項の規定により権限を委任された警察署長を含む。以下この条において同じ。）は、第四条第一項の規定に基づき、第二条第一項第三号、第三号の四、第四号、第四号の二若しくは第七号、第四条第三項、第八条第一項、第十三条第二項、第十七条第四項、第五項第五号若しくは第六項、第十七条の二第一項、第二十二条第一項、第二十三条、第三十四条第五項、第四十九条第一項、第六十三条の四第一項第一号又は第六十三条の七第二項の道路標識等（第十七条第六項の道路標識等にあつては内閣府令・国土交通省令で定めるものに限り、第二十二条第一項の道路標識等にあつては同項の政令で定める最高速度を超える最高速度に係るものに限る。以下この条において同じ。）により交通の規制を行おうとするときは、当該規制の適用される道路（第二十二条第一項及び第六十三条の四第一項第一号の道路標識等以外の道路標識等に係る場合にあつては、道路法による道路に限る。）の管理者の意見を聴かなければならない。ただし、第八条第一項の道路標識等による交通の規制を行う場合において、緊急を要するためやむを得ないと認められるときは、この限りでないものとし、この場合には、事後において、速やかに当該交通の規制に係る事項を通知しなければならない。
Notwithstanding the main clause of the preceding paragraph, before regulating traffic on a national expressway or limited highway based on Article 4, paragraph (1) using road signs or markings as referred to in the main clause of the preceding paragraph, Article 17, paragraph (5), item (iv), Article 30, Article 42, or Article 75-4, a public safety commission must consult with the manager of the road in question. The proviso of the preceding paragraph applies mutatis mutandis to such a consultation.
Before prohibiting Stopping and parking or parking based on Article 4, paragraph (1) on a part of the road that road signs or markings as referred to in Article 44, paragraph (1) or Article 45, paragraph (1) show to be an on-street parking spot, a public safety commission must specify the timeframe of that prohibition after hearing the opinion of the local government that set in place the on-street parking spot regarding the fact that it seeks to prohibit this and the timeframe of the prohibition. In such a case, the commission may implement the prohibition without hearing the opinion of the local government if urgent circumstances are found to compel this, and when it has implemented the prohibition, it must promptly give notice of the fact that it has implemented the prohibition and of the timeframe of the prohibition.
Before designating, based on Article 4, paragraph (1), a part of the road that road signs or markings as referred to in Article 49, paragraph (1) show to be an on-street parking spot as a time-restricted parking zone, a public safety commission must hear the opinion of the local government that set in place the on-street parking spot.
If a parking space maintenance plan (but only one in which the particulars set forth in Article 3, paragraph (2), item (iv) of the Parking Spaces Act have been provided for) has been established pursuant to Article 4, paragraph (1) of that Act, before designating a time-restricted parking zone, based on Article 4, paragraph (1), using road signs or markings as referred to in Article 49, paragraph (1) within a parking space maintenance zone as prescribed in Article 3, paragraph (1) of the Parking Spaces Act, a public safety commission must hear the opinion of the municipality that has established the plan.
