Like rdale said... each location (county/city) has their own "Levels". In Franklin County we are under a Level 2 which means the only people allowed on the roads are those responding to an emergency. I got to go out and play a little while ago... Our dept. was toned for a tree and electrical lines down and blocking the road. When we got there it was only a phone line, and the tree was quickly cut up and removed from the road. I believe State and Federal roads/highways are exempt from being closed by local officials.
