That’s the legal purpose of a yellow light, yes. However people have been getting worse and worse with actually following it. Now on green I always wait a few seconds for some yahoo to come flying through on the side street claiming he made it on yellow
In Canada yellow means stop, unless it’s too late to stop then you need to get through the intersection during the grace period before it turns red.
Does it mean something else in the USA?
no, that is pretty much what it means in the USA. it is a heads up the light will be red in a moment
