For the continuous flashing yellow light, the vehicle and pedestrians are reminded to pay attention to the passage and confirm the safety and pass. This kind of lamp does not control the role of traffic advancement and letting, some hanging over the intersection, and some use the yellow light plus flash when the traffic signal is stopped at night to remind the vehicle and pedestrians that the front is an intersection. Be cautious, watch and pass safely. At the intersection where the flashing warning light flashes, when vehicles and pedestrians pass, they must abide by the principle of ensuring safety, and also comply with the traffic regulations that do not have traffic signals or traffic signs to control intersections.
