About a month and a half ago, I got into a bad car wreck in an intersection. I was turning left and I had a green arrow and a green light, so I went. Bad idea.
What I'm still really confused about is this: When I have a green light AND a green arrow, what does that mean? And when I have a red light and a green arrow, what does that mean?
I just got a new car and I don't want to make the same mistake twice.
