Priority A: Interstates, parkways and major arteries such as US 23, US 60, KY 11 and KY 32, etc., with the highest traffic volume. While all roads are treated during a winter storm, these receive top priority with a goal of a one-hour turnaround time on interstates and two-hour turnaround on other A routes.
Priority B: Highways that are not as heavily traveled as ‘A' routes, which include KY 111, KY 36, KY 2, KY 5, etc., are treated next. All Priority B routes should be completely treated during a routine winter storm with a goal of a four-hour turnaround.
Priority C: Mainly rural and other low-volume routes are third on the list. The cabinet's goal is to treat Priority C routes within 8 hours of the beginning of a routine snow event, and with an 8 hour turnaround time after that.
