HEBER CITY — A father and son from Las Vegas suffered serious injuries Monday when their sport-utility vehicle rolled after being hit by a tractor-trailer truck near Strawberry Reservoir.

The crash happened about 9:10 a.m. when John F. Mahan failed to yield to the tanker truck as he turned his Ford Explorer left onto U.S. 40 from a side road, according to Utah Highway Patrol Cpl. Todd Johnson.

The tanker truck slammed into the side of the SUV near the rear tire, causing the smaller vehicle to roll.

Mahan, 63, was wearing a seat belt and remained in the SUV. His son, 43-year-old John F. Mahan Jr., was not wearing a seat belt and was ejected, Johnson said.

Both men were taken to Heber Valley Medical Center by ambulance. They had been released from the hospital Monday night.

Troopers cited the elder Mahan for failure to yield, Johnson said.

The driver of the tanker truck, 51-year-old Scott Ray Adams of Roosevelt, was not injured in the crash.
