The July 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 the 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 wasn't 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 appear in court again on July 17 for a pretrial conference.
