It’s difficult to say at the exact time of the collision, but at about the 21:00 mark, it clearly shows the light red for the vet’s direction of travel.
Yes. As I noted, at 20:55 you can see a green light in the vette’s direction of travel, I also note that you can see the signal turn yellow.
Guess what happens next?
See post #37, re-watch the video, and get back to us, m’kay?
