It seems like a lot of people in Utah are crazy drivers. Throw in hills and curves and you will get accidents. Not a lot of hospitals near by either.
Be careful driving and watch out for other divers. Even people who I have spoken with in Utah say there are wild drivers out there.
I wasn't sure where to put this. At first I found it quite comical and actually not the first time I've seen this in Utah. Came across the same thing in Torrey, Utah. I'm sure this is suppose to be a deterrent against speeders as they pass through Kanab. But as a tourist, if you are in need of assistance, probably not so funny if you approach the patrol car to ask for help.
