I can't give you a straight answer to this because it comes down to "interpretation" by the local state or local police. Here in my area, I have a 12,000 pound Bri-Mar trailer., As such, any trailer over 10,000 GVW requires a CDL or supplement to your license. For me, I would cross the scale anyway.. Most areas, I do believe really don't push the issue and probably will let you drive by. Best thing to do is call your local state police and Dpt of transportation. Ask them the same questions, and thereby, you will know how they "interpret" the laws in your district..
