A one-vehicle accident caused a backup in Prescott Friday morning. Fire officials say crews were called to the roundabout at Willow Lake Road and Highway 89 at around 7 a.m. on reports of an accident. When the first crew arrived, they found a work truck that had overturned going through the intersection. One person was in the truck, and he was able to get out of the vehicle unharmed. He refused transportation to a nearby hospital. The area was cleared and traffic went back to normal a short time later. No other vehicles were involved in the accident.
