Deputies responded to a four-vehicle crash Friday morning around 5:50 a.m. in the area of E. Highway 95 and S. Avenue 5E.
YCSO said a white 2002 Chevrolet Trailblazer was driving westbound on E. Highway 95 when it merged into oncoming traffic and crashed with a gold 1999 Toyota 4Runner driving eastbound.
