You read right, the one person who is supposed to stay sober for the ride home gets busted for DUI.  

The driver was participating in a college van program to provide a safe way for drunk college students to get back to the dorms or home safely.

The University of Colorado "Ram Ride" is the program the driver was taking part in and the liquored up driver was pulled over for speeding and then arrested for DUI.  His passenger was reportedly another one of the volunteers for the program.
