Emergency personnel responded shortly before 3 p.m. Monday to a crash involving an Illinois Department of Transportation truck on I-255 southbound near milepost 11.

Responding agencies included the Dupo and Prairie du Pont fire departments and Illinois State Police.

The crash resulted in I-255 southbound traffic backing up to milepost 13.

ISP said a maroon 2007 Maroon Freightliner driven by Leslie Jackson, 50, of St. Louis was traveling south on I-255 near milepost 11 in lane three. An orange 2013 International IDOT truck driven by Eric Woodcock, 40, of Columbia, was stationary in lane three providing traffic control with yield sign and emergency lights activated for road maintenance south of the incident. The driver of the Freightliner failed to reduce speed and struck the rear of the IDOT truck, ISP said.

Both drivers were transported by ambulance to an area hospital for non-life-threatening injuries.

Jackson was cited for improper passing of an emergency vehicle and failure to reduce speed to avoid an accident.
