Most people who are charged with DUI in Colorado and seek an attorney have done so when driving an ordinary passenger car.  However, there are a few who are more creative and present new challenges for their DUI defense attorney.  This story involves a gentleman who backed his bulldozer into a river at 1:30 in the morning.  To be clear, one does not have to be driving a car or truck to be charged with drunk driving.  Operating any motor vehicle as well as bicycles and other modes of transportation can result with a trip to DUI court.
