I just know you can go about 80mph until you get pass the state line into Tenn.Then might wanna slow down.My girl scared the shit out of me when I was sleep and she went from 95mph to like 65mph after seeing three white tahoes with off road equipment.Lol Tenn. and AL. ride in Tahoes she didnt know.But all the ones I seen were white with black beadlock wheels and tint.They sit in the clearings in between the threes you cant see them until you get close.But in the end I say just ride 75-80mph and youll be ok.
