A Modesto woman died Sunday afternoon when the all-terrain vehicle she was riding hit a levee berm, the California Highway Patrol said.
The 34-year-old, whose name was not released, was riding the Honda Ranchero ATV in an orchard near McHenry Avenue and Patterson Road when the accident occurred just before 4 p.m.
The ATV, which was moving at high speed, hit a levee and the woman flew off the vehicle. She was taken to Doctors Medical Center, where she was pronounced dead.
The woman was not wearing a helmet, the CHP said. Authorities do not believe alcohol or drugs was a factor in the accident, which remains under investigation.
