The Ohio Department of Transportation and the Youngstown Road Department had trucks out early Tuesday pre-treating wet roads to prevent them from turning icy as temperatures plummet.

The temperature was already below freezing by 4 am, heading into the teens this afternoon.

Authorities in Trumbull County were called out to a couple of accidents between 4 and 6 am.

A truck rolled over on North River Road just east of North Road in Howland shortly before 5 am, temporarily closing the road.
