SAVANNAH, GA (December 21, 2012) Traffic investigators are trying to determine if a medical condition could have caused a Savannah man to drive the wrong way on the Truman Parkway today, causing several crashes.

Joseph Sero, 42, of Autum Leaves Court, was transported to Memorial University Medical Center after the Jeep Cherokee he was driving crashed head-on into another Jeep Cherokee on the overpass across Victory Drive about 1:30 p.m.

Investigators are trying to confirm if low blood sugar could have caused a medical crisis that disoriented him.

Thomas Wood, 29, of Chevis Road, the driver of the other Jeep, was transported for treatment as well.

Officers from the Major Accident Investigation Team (MAIT) of the Savannah-Chatham Metropolitan Police Department, determined Sero entered the divided highway driving north in the southbound lanes at Eisenhower Drive.

His Jeep sideswiped and overturned one car almost immediately, then was involved in a second collision near Derenne Avenue before the final crash on the Victory overpass.

Metro police closed the southbound lanes between Victory and Eisenhower and portions of the northbound lanes between Eisenhower and Derenne and all entrances to the highway until 5 p.m. for the investigation and cleanup.

MAIT continues to investigate the incident.
