A 60-year-old Georgia man is dead after tipping his semi on Interstate 80 west of Cheyenne.

The Wyoming Highway Patrol says the accident happened around 5:23 a.m. Sunday.

The Patrol says Charles Mosteller was headed west on I-80 when he failed to negotiate a right-hand curve near milepost 337, went into the median and tipped his rig onto the driver's side.

Mosteller was wearing his seat belt, but died from his injuries.​

The Patrol says it's possible Mosteller fell asleep or had a medical condition which led to the crash.
