One person was killed and five were taken to the hospital after a wreck involving a tractor-trailer and six motorcycles on Interstate 85 southbound in Greensboro, Friday morning.
Officials said six motorcycles from out-of-state were parked on the side of the road taking a break when a tractor-trailer hit them.
Witnesses said they saw the tractor-trailer swerve and go off the road, hitting the motorcyclists.
The truck then came to a stop further up on I-85.
Authorities said the tractor-trailer is out of Florida and there was a passenger in the front seat.
After speaking with the tractor-trailer driver, troopers said they think he fell asleep at the wheel. Troopers said they think the only reason he stopped about half a mile up the road is because he had a flat tire from the crash.
The names of the victims are not being released yet, but troopers did say they are all from Virginia.
The investigation is ongoing.
