Robert Kuchcinski was driving an 18-wheel tractor-trailer on Interstate 15 near Tremonton on June 16, 2012, when he reached for something across the cab, causing the truck to drift out of its travel lane. A Utah Highway Patrol trooper stopped Kuchcinski and cited him with failure to stay in his lane, a class C misdemeanor. The trooper then required Kuchcinski to take Breathalyzer and field sobriety tests. Kuchcinski had difficulty with a balance test, which he told the trooper was likely due to a severe inner-ear infection, according to the court filing.
