A 57-year-old man died Tuesday when he lost control of his UTV.

The accident happened at about 3:37 p.m. in the open desert of the Imperial Sand Dunes Recreation Area. The Lake Havasu, Arizona man apparently lost control of a 2009 Polaris Ranger causing the UTV to overturn. The driver was wearing a helmet but was not wearing his safety belt. He was pronounced dead at the scene. The accident remains under investigation.
