求翻译：在繁忙的十字路口，四面都悬挂着红、黄、绿、三色交通信号灯，它是不出声的“交通警”。红绿灯是国际统一的交通信号灯。红灯是停止信号，绿灯是通行信号。交叉路口，几个方向来的车都汇集在这儿，有的要直行，有的要拐弯，到底让谁先走，这就是要听从红绿灯指挥。红灯亮，行或左转弯，在不碍行人和车辆情况下，允许车辆右转弯；绿灯亮，准许车辆直行或转弯；黄灯亮，停在路口停止线或人行横道线以内，已经继续通行；黄灯闪烁时，警告车辆注意安全。是什么意思？

In a busy intersection, surrounded by hanging red, yellow, green, three-color traffic lights, it is no sound of traffic police. The traffic light is the international harmonization of traffic lights. The red stop signal, the green traffic signal. Crossroads of several directions to the car together
