In general, two significant classes of vehicles are considered when DUI charges are filed: personal vehicles and commercial motor vehicles (CMVs). A personal vehicle is any vehicle that is owned or leased by an individual for personal use. A personal vehicle can be a car, truck, SUV, motorcycle, or even a riding lawn mower for the purposes of DUI law.
A commercial motor vehicle is a vehicle that requires a commercial driver’s license (CDL) to operate. Individuals with a CDL are held to a higher standard for acceptable blood alcohol content (BAC) and can lose their CDL if they are convicted of a DUI or refuse to take a BAC test. It does not matter if the CDL holder was charged with a DUI in their personal vehicle or their work vehicle; they may still lose their CDL license for a year or more.
