FAYETTEVILLE, N.C. (AP) - A highway worker has been killed after a tractor-trailer careened into two safety vehicles along Interstate 95 in North Carolina before crushing a tractor mowing the median.

The Fayetteville Observer reported the truck scraped two parked vehicles warning about a lane closed to protect workers ahead.

The Highway Patrol says the truck then rear-ended the mowing tractor just north of Fayetteville, killing the worker just before noon Wednesday. Mower driver John Glenn McLean of Erwin was one of several family members working for a company with a contract to cut grass for the state Department of Transportation.

Tractor-trailer driver Luis Valdes of Lehigh Acres, Fla., was taken to a hospital for treatment.

Trooper Greg Steffens says the wreck is under investigation.
