Oh, boy, that sucks. Kentucky has one of the strictest Move-Over laws. I was asking because most states, including mine, classify "failure to yield to an emergency vehicle" as a petty traffic offense, not a misdemeanor.
Consult a traffic attorney and see if they can get it dismissed by the SA's office in exchange for you taking a traffic safety class and being put on probation. If it doesn't work, even though it's a Class B misdemeanor, it's just a moving violation (which I'm assuming didn't result in any harm) and shouldn't affect your chances much as long as you can explain what happened. Drug, theft, and violent offenses are what raise red flags.
