If you're talking about Bristol/Kingsport/Johnson City, I frequent those area's a few times a year. Have some friends that are more like family that live in Kingsport.
Just giving you fair warning in advance
Just kidding.
Pretty good area. Least, most of it.
I will also give you a heads up that if you venture across the state line into the Virginia side of it, they will pull over out of state tags 10 to 1 before they will VA tags.
Window tint is frequent ticket that they give you the option of sitting there on the side of the road and remove it or be issued a ticket. Most people will just take the ticket.
They also look for any type of vehicle infraction that they can. Poor tire tread, speeding, riding too close to the white line, etc.
I have lots of family that drive commercial trucks. They have even been known to make them sit on the side of the road and slide a big white piece of cardboard under the cab to see if the vehicle is leaking any fluids. More than 2 drops in a half an hour and you're wrote up.
