Get a attorney in or around Dover, TN. Spend the money if you have it. If you just don't have the money and you don't want to or can't go to court in Dover, then pay the ticket, but you just pay the ticket, you will be pleading guilty and will probably get the points on your driver's license. if you hire an attorney, he might be able to stop the points on your driver's license.
22 miles per hour in Kentucky carries 6 points on any road or highway in this state (16-25 mph over speed limit). In addition to the points there will be an assessment of approximately of a $44.00 fine plus approx. $135.00.
I would contact local counsel in Dover, TN to see if the charge can be amended (if you were on the highway) or to see if they have some type of diversion program.They may have a referral to drivers reeducation program so that points won't be assessed on your license.
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
