NEAR NASHVILLE (CNN) -- One person was killed and 16 others injured Thursday in three separate chain-reaction crashes involving 176 cars north of Nashville, authorities said.
Heavy fog and black ice were thought to have contributed to the crashes on State Highway 386 in Sumner County, said county emergency medical services Capt. Vincent Riley.
The name of the deceased victim has been identified as 28-year-old Paul Warren of Hendersonville, TN.
Police are treating the incident as four separate wrecks that all happened within the span of a few minutes.
Hendersonville police say the series of wrecks began at 6:56 a.m. Traffic stopped and another pile-up happened. The third pile-up was the one that caused Warren's death. The fourth crash happened shortly thereafter.
The wrecks covered a two-mile stretch of Vietnam Vets Boulevard, beginning roughly at the bridge over Gallatin Road and ending close to the Saundersville Road exit.
The incidents began when a car ran off the highway and caused a chain reaction accident in "heavy, heavy fog," he said.
At least one school bus, with children aboard, was involved in the crashes, he said. None of the children were injured.
The man who died was driving a compact car that went under a semitrailer, Riley said. The 16 people transported to local hospitals were not critically injured, he said.
The highway remained closed throughout most of the day as authorities attempted to clear the wreckage. As of Thursday afternoon, one side of the highway was still blocked with 50 cars that were not driveable.
