Types of traffic lights with meanings
||Pedestrians may proceed and cross.|
|Vehicles other than lightweight vehicles, and streetcars/trams may go straight or turn left or right. Mopeds making two-step right turn may go straight ahead to the point for turning right, and change the direction they are heading.|
|Lightweight vehicles (bicycles, carts, etc.) may go straight and turn left. When turning right, these vehicles must proceed to the point of making a right turn, stop and change their direction to the right and wait at that point.|
||Pedestrians must not start to cross.
A pedestrian who is already crossing the road must finish crossing quickly or else turn back.
|Vehicles and streetcars/trams may not move further than the stopping point. However, if a vehicle is rapidly approaching the stopping point when the signal changes to yellow, and cannot stop safely, it may continue to proceed.|
||Pedestrians must not cross.|
|Vehicles and streetcars/trams may not proceed past the stopping point.|
|A vehicle or streetcar/tram, when already making a left turn at an intersection, may continue to proceed even if the signal light on the left is red.|
|A vehicle or streetcar/tram, when already making a right turn at an intersection, may continue to proceed even if the signal light on the right is red. In this case, the vehicle or streetcar/tram, must not obstruct the traffic of vehicles or streetcars/trams approaching on a green light. However, lightweight vehicles and mopeds making a two-step right turn must stop after crossing the road and wait at that point while the signal light on the right is red.|
|Green arrow light
||Vehicles may proceed in the direction indicated by the arrow even if the signal light is yellow or red. (Vehicles may also make a U-turn when the signal arrow is indicating a right turn.) However, in the case of a signal arrow indicating a right turn, lightweight vehicles and mopeds making a two-step right turn may not proceed.|
|Yellow arrow light
||Streetcars/trams may proceed in the direction indicated by the arrow even if the signal light is yellow or red, but pedestrians and vehicles may not proceed.|
|Flashing yellow light
||Pedestrians, vehicles and streetcars/trams may proceed carefully, paying attention to other traffic.|
|Flashing red light
||Pedestrians may proceed carefully, paying attention to other traffic.|
|Vehicles and streetcars/trams must stop at the stopping point before proceeding.|
(Note) The term “stopping point” in this table refers to the point just before the stop line. In the absence of such a line, it is defined as follows:
- 1.A point just before an intersection (where a crosswalk/pedestrian crossing or a bicycle crossing lane is located close to an intersection, just before the crosswalk/pedestrian crossing or the bicycle crossing lane);
- 2.A point just before a crosswalk/pedestrian crossing, a bicycle crossing lane or a railroad crossing in places other than intersections; or
- 3.The point where a traffic lights can be seen in places other than intersections without a crosswalk/pedestrian crossing, bicycle crossing lane or railroad crossing nearby.
The term “vehicles” refers to automobiles, mopeds, lightweight vehicles such as bicycles and carts, and trolley buses.
