Investigators say Ashley Singleton of McMinnville was heading north on Congress Boulevard Friday afternoon when she slammed her Chevy Trailblazer into the rear of a TDOT truck driven by Jarrod Bonar of Lascassas. The TDOT truck had slowed for a red-light. Singleton had her children, ages eight and 10 with her. One of them was taken to the hospital by private vehicle for treatment of noncritical injuries. She was cited for failing to use due care.
