我在美國考的，沒有聽過這個說法！


Signals lie
Never enter an intersection at the top of the posted speed, even if you have a solid green light. A green light at an intersection is an indicator that you have the right-of-way. But a green light cannot think or see and will not stop another oncoming vehicle. Don’t trust them.

Slow down
Slow down slightly before entering an intersection and see for yourself that it is safe to enter. The immediate danger is the traffic coming from your LEFT on the cross-street. Look left first to make sure all traffic is stopped or stopping before you enter the intersection. Then look right. If it is safe, enter the intersection and roll through with your foot off the accelerator and covering your brake.
