Green light = go
Red light = stop
Yellow light = go like hell so you don't have to stop
I've started through a green light before it turned, but I won't go that far through an intersection until I see the green...
But one night when I lived in Missouri I ran a COMPLETELY red light, and what's more is I didn't even know it until the 8-year-old in the back seat said something about telling my aunt :o Then I looked back in the rear view and realized that he was totally right!
