红灯停下等着英语怎么说

"红灯停下等着" 的英文表达为 "stop at a red light and wait."

这个表达的来源可以追溯到交通信号系统的使用。在交通信号灯的信号系统中，红灯表示停止，黄灯表示准备停止，绿灯表示通行。所以当车辆在红灯时，就需要停下来并等待绿灯出现，才能继续行驶。

下面是一些英文例句及其中文翻译：

"I had to stop at the red light and wait for it to turn green before I could continue driving."（我必须在红灯处停下来，等待它变成绿灯才能继续开车。）
"The traffic was heavy, so I had to stop at every red light and wait for it to change."（交通很拥挤，所以我必须在每个红灯处停下来，等待它变化。）
"I was in a hurry, but I couldn't run the red light. I had to stop and wait for it to turn green."（我很匆忙，但我不能闯红灯。我必须停下来等待它变成绿灯。）
