A Franklin County man was seriously hurt early Saturday when the car he was riding in ran off Interstate 44. 

The Missouri Highway Patrol said Jason C. McIntosh, 39, Labadie, was a passenger in an eastbound 2008 Cadillac driven by Michael Johnson. The patrol report did not list an age or city for Johnson, who was not injured.

The patrol said the car ran off the left side of I-44 at mile-marker 237 and struck a tree about 1:30 a.m. 

McIntosh was taken by St. Clair Ambulance to Mercy Hospital Washington for treatment.
