In the first crash, one man died and three others were hurt after colliding with the plow on U.S. 250 just east of Wilmot in Stark County Friday morning.
Troopers say the driver of a Dodge Neon was west bound on U.S. 250 when he lost control and went left of center striking an Ohio Department of Transportation snow plow in the eastbound lanes.
There were four men in the car. Troopers say the passenger in the front seat, a 21-year-old male, died at the scene.
The driver was transported to Union Hospital in Dover with minor injuries. The two passengers in the back were taken to Aultman Hospital in Canton with serious injuries. The driver of the snowplow was not hurt.
No identities on those involved have been released.
In the second crash, an accident south of Youngstown, 22-year-old Rodney Van Meter
of Canfield was killed when his car ran off the side of slushy Ohio 11 and struck a parked state highway snow plow truck.
Weather conditions may have played a role in the accidents, but both remain under investigation.
The area was under a Winter Weather Advisory at the time of the accident with snow, sleet and freezing rain predicted.
The storm dropped several inches of snow on much of Ohio and forced the cancellation of some flights at Port Columbus International Airport.
