I recently got nailed going 55 in a 25 zone. Oops.
AZ state law states that any time you go 20 mph over the posted speed limit, or 86 mph, whichever comes first, it's a misdemeanor, criminal speeding.
I was very nice to Mr. Officer Sir and he wrote it up for failure to observe posted traffic control devices, which is a "regular" speeding ticket and I was able to go to driving school. Otherwise, it would have been ( I think) three points on my license, a big fine and a mandatory appearance at the local courthouse.
