绿灯亮时，准许车辆通行，黄灯闪烁时，已越过停止线的车辆可以继续通行；没有通过的应该减速慢行到停车线前停止并等待，红灯亮时，禁止车辆通行。给行人看的叫人行横道灯，通常指由红、绿（绿为蓝绿）二种颜色灯组成用来指挥交通通行的信号灯，红灯停，绿灯行。(When the green light is on, the vehicle is allowed to pass. When the yellow light is flashing, the vehicles that have crossed the stop line can continue to pass.You should slow down to stop and wait at the stop line. No traffic is allowed when the red light is on.Pedestrian crossing lights for pedestrians, usually denoted by red, green (green, blue, green), two color lamps used to direct traffic signals, stop at red lights and green.)
