①A police or traffic patrol officer as prescribed in Article 114-4, paragraph (1) (hereinafter referred to as an "officer") may control traffic using hand signals and other signals (hereinafter referred to as "alternative signals"). On finding it to be particularly necessary to do so in order to prevent road hazards and otherwise ensure the safety and fluidity of traffic, an officer may use an alternative signal with a different meaning from that of a signal displayed by a traffic light, regardless of the signal displayed by the traffic light.

②On finding a compelling reason to do so in order to ensure that traffic runs smoothly on a road (other than a national expressway or limited highway; the same applies in paragraph (4)) on which severe traffic congestion is likely to occur due to a severe back-up of vehicle or streetcar traffic, a police officer may prohibit or restrict vehicles or streetcars from entering a location or order the driver of a vehicle or streetcar at the location to back up or comply with different traffic rules than those prescribed in Article 8, paragraph (1), or Chapter III, Section 1, 3, or 6, but only so far as is necessary in order to reduce congestion.

③On finding the measures prescribed in the preceding paragraph to be insufficient to reduce congestion at a location, a police officer may issue the necessary instructions to relevant persons at the location, but only so far as is necessary to reduce congestion.

④When there is a risk that a traffic hazard will arise on a road due to road damage, an outbreak of fire, or other circumstances, and a police officer finds there to be an urgent need to prevent a hazard on that road, the officer may temporarily prohibit or restrict the passage of pedestrians, etc. or vehicles or streetcars on that road, but only to the extent necessary.

⑤Cabinet Order provides for the meanings of alternative signals referred to in paragraph (1).
