Charlie, he's talking about the vehicle, not the driver. You're speaking of the driver's license, which has different requirements in different states. In Colorado, for example, I don't need anything other than a regular drivers license to legally drive a 45 foot, 50,000 lb. coach. In other states, anything over 26,000 lbs. needs some other license. But none of the affect the legality of the vehicle itself.
But in Illinois you DO. This is right out of the book.
In Illinois if the vehicle is over loaded on any axle it is parked until it IS made legal.
I know in the last couple of years the State Police have been stopping many drag racers with MH pulling enclosed trailers looking for infractions. I know one guy personally that was stopped and his rig impounded because he did NOT have the correct licence. He had his trailer lettered and the cop said he needed a CDL to drive the rig, because it was a commercial rig. The guy went to court, and lost ! He had to either remove the lettering or get a CDL to drive it.
