(STMW) — A 28-year-old woman has been charged with driving under the influence after she crashed into the back of an Illinois State Police trooper’s vehicle who was in the middle of a traffic stop early Sunday on the Kennedy Expressway near Bucktown on the North Side.

Kendra Hernandez, of the 1000 block of Argyle Street in Bensenville, was charged with aggravated driving while under the influence, failure to yield to an emergency vehicle, improper lane usage and driving with a suspended license, according to Illinois State Police.

The crash happened shortly after 2 a.m. in the outbound lanes of Interstate 90/94 near Damen, sending the trooper’s car into the back of the vehicle he had originally pulled over, state police said.

The trooper was not in his car when it was rear-ended and was not hurt, police said.

Hernandez was taken to Advocate Illinois Masonic Medical Center with injuries that weren’t considered life-threatening, police said.
