1、交通规则traffic rules或者traffic regulations
遵守交通规则obey the traffic rules 或者observant of the traffic rules
You should be observant of the traffic rules.你应当遵守交通规则。
2、违反交通规则break the traffic rules 或者be against the traffic rules
If we break the traffic rules, we will get a fine and even be in danger.如果我们违反了交通规则，我们会收到罚单甚至处于危险状态。
3、很多人都会将“闯红灯”说成”break the red light”，这是不对的，真正的表达是”run the red light”,而break用于违反规则、法律等，像上面提到的break traffic rules.
Love life,refuse running red lights.珍爱生命，拒绝闯红灯。It's dangerous to run through the red light.闯红灯是非常危险的事。
5、为了不闯红灯，那就要等红灯啦，那么“等红灯”用英语怎么表达呢？千万不要说出wait for the red light,“等红灯”的目的其实是等红灯变绿，正确的说法就是 wait for the green light或者wait for the red light to change.
I'm waiting for the green light.我正在等红灯。
6、“green light”不仅有“绿灯”的意思，也有“准许”的意思。很好理解，其实就是给别人在心里开绿灯。
“give sb/sth the green light”意思是“给某人/某事许可”
“get the green light”则是“得到许可”
My boss gave me the green light to start the project.我老板同意我开始这个项目了。If we want to go outing, we must get the green light from the teacher.如果我们想外出旅游，我们必须得到老师的批准。
