It's common sense to move away from any lane where you see an emergency vehicle along a roadway. In Missouri, it's more than just a good idea or suggestion though. As a matter of fact, you can get a serious fine for violating Missouri's Move Over law. It can cost you seriously big bucks.
It's no secret there are automated red light ticket cameras in Hannibal, Missouri and there's been talk of them being installed in St. Louis. Would you drive differently in the big city if there was an eye in the sky watching you?
I am not a lawyer and don't play one on TV either, but I have done some research into whether or not you can get a ticket for not abiding by a yellow advisory sign in Missouri. The short answer is it's very complicated.
If you cast a wary eye on red light ticket cameras when you pass them in Illinois, you should know there is a new law involving them that may affect future traffic regulators being placed in an intersection near you.
