This happened to me once as a passenger. The left turn arrow turned green and the driver thought she had a green light and went through the intersection even though we now had traffic coming at us. Little scary as a passenger, but nothing happened overall.

I also once was taking a left turn and did that thing where you wait in the middle of the intersection till it turns red and then go. Turns out a cop was directly behind me lolol I got pulled over and let go with a warning.

You'll be okay 💜
