Police charged Matt Roloff with a DUI in June 2007 when a deputy followed his vehicle leaving a bar and subsequently stopped Roloff for erratic driving. At the time of the traffic stop, Roloff was driving a 2005 Chevrolet van through an unincorporated area of Washington County, Oregon. In January 2008, Circuit Judge Donald R. Letourneau found Roloff not guilty.
Roloff claimed the reason he had appeared to be driving erratically was that it was difficult for him to control the vehicle because it was equipped with smaller pedal and brake extensions for his wife. Both Roloff and his wife, Amy, have dwarfism diagnoses. Roloff further claimed that he had dropped someone off in the bar parking lot. A witness from the bar testified that he had not seen Roloff drinking that night; however, the Washington County police report of Roloff's arrest noted that he had failed the field sobriety test and had refused to take the breathalyzer test. Judge Letourneau ruled in favor of Roloff, asserting that the prosecution had not proven beyond reasonable doubt that the defendant had indeed been intoxicated.
Police had previously charged Roloff with a DUI in 2003 after he swerved his vehicle off the road and into a ditch. The charge was dismissed upon Roloff's successful completion of an alcohol diversion course.
Matt Roloff has a type of dwarfism called diastrophic dysplasia, which was the result of repetitive surgeries during his childhood. He works as a computer software salesman for Direct Access Solutions, which he co-founded, and Amdocs. Roloff appears on the television show "Little People, Big World," which airs on TLC as of 2015. Roloff and his wife, Amy, are active in philanthropy related to dwarfism.
