An 11-year-old girl stopped a van that went out of control when her diabetic mother became ill, police said.

Indiana State Police Senior Trooper Joe Swisher said Abigail Parker's actions were "nothing short of heroic."

Besides stopping the van, Abigail kept her mother and 8-year-old brother calm and informed paramedics about her mother's condition, Swisher said.

State police dispatched an ambulance and troopers to U.S. 31 south of Peru on Saturday after the girl called 911 and another person reported a reckless driver.

Officers found the van stopped, partially blocking the southbound lane of the highway. Deborah Parker, 36, of Muncie, who had been driving, was unaware of her surroundings. She was treated for low blood sugar.

Abigail told police her mother had started driving erratically at about 80 mph. The girl said she climbed from the rear seat of the van onto the woman's lap and managed to stop the vehicle before calling 911.
