The July 7, 2012 accident killed 88-year-old Arline H. Logan, who was riding in a Buick going south from a side street through a green light onto U.S. 89, police have said.
Stephens-Applonie was driving an ambulance westbound with lights and sirens on, and a critically injured car-crash patient onboard, when it hit the Buick, South Ogden police Officer Marci Edwards said last year.
The ambulance then crashed into two stopped cars in the eastbound lanes carrying four people.
Logan was taken to Ogden Regional Medical Center, where she died.
Stephens-Applonie was not hurt, but three other emergency medical responders were treated at McKay-Dee Hospital Center and Ogden Regional and released.
Three people in the stopped cars also were treated at McKay-Dee and released, Edwards said.
Stephens-Applonie will be back in court on Nov. 6 for a pretrial conference.
