Tennessee passed a new law (copy attached) that was signed into law in April, 2016. This allows you to register a UTV as a “Class I off-highway vehicle. The registration fee is $10 (plus any applicable County wheel tax). It allows you to drive on any county road in the state. You cross over a state or federal highway, but can’t drive on them. You still have to have required safety equipment as noted above, but the affidavit is no longer necessary. I registered mine on Wednesday in Knox County. I printed out the statue in case I had any issues, but it was no problem at all. The person at the DMV who helped me said she’s been familiar with the new law since it passed, but I was the first person to actually come in and register with the new Class I status. It does appear you must be a TN resident to register.
I went out for a drive Wednesday night and drove right past a stopped police care. He waved and smiled as a drove by. Hope to see more RZR’s out on the road!
