Kentucky State Police Trooper Jeff Gregory said Jonathan French died and his mother, Lisa French, was taken to a hospital with what appeared to be non-life threatening injuries. The crash occurred in Hardin County along Interstate 65 about 3:30 a.m. Wednesday, about a mile north of Glendale.
The mother and son were getting equipment off the fire truck when it was hit. Firefighting runs in the French family. Lisa French is the sister of the chief of the Glendale volunteer fire department.
Police say firefighters had been called to a vehicle fire on the interstate's shoulder. No charges have been filed.
