Excerpts from the ChicagoTribune.com:

Three people were injured Thursday afternoon when a Palatine Fire Department ambulance responding to a call was struck by another vehicle.

The crash happened about 2 p.m. when the ambulance was westbound on Palatine Road at Rohlwing Road and was struck by a van that was northbound on Rohlwing. The ambulance rolled onto its side. Two other vehicles sustained minor damage after being hit by the van and a traffic signal.

Two firefighter/paramedics who were in the ambulance and the driver of the van were taken to a hospital with non-life threatening injuries.
