ATV and dirt bike operators are now going to be allowed on some county roads in Wise County. The ordinance, approved by the county Board of Supervisors, sets basic rules to allow ATV and other off-road recreational vehicles on roads and highways within the county. County Attorney Karen Mullins said the ordinance is not a blanket authority for off-road vehicle operators to drive on all county roads, though.Mullins said the county will have to coordinate with the Virginia Department of Transportation to designate roadways for authorized off-road vehicle use.
