A standard licence is all thats needed , as long as the vehicle is under 18,000 lbs , 9 tons U.S. , Of course the vehicle is also registered as an antique and insured as such . Which gives you a reduced premium but there are limits as a result , you cant use the vehicle a daily driver , you cant haul cargo or use for business but you can drive it as needed to check it mechanically say after any drive line repairs , you can drive to and from events , if you belong to a group, or to parades or displays and some states limit operation to daytime or weekends. I have only recently relocated and will have to check if any other laws apply in this state.
