Just heard a guy on the radio talking about getting nailed by DOT commercial vehicle enforcement (the blue cars) for improper vehicle license and drivers license on a RAGBRI support bus. Seems they say you must have a commercial plate that covers the full GVWR of the bus and a commercial drivers license. Several people were ticketed between Manchester and Dubuque. I don't have a bus, but it appears there may be a general misunderstanding of the law in some of our county courthouses. If you have a tailgating bus you might want to look into it. Fines were apparently running between 600 and 900$.
