A teen motorist who allegedly ran a red light struck an ambulance Monday night in Blaine and caused the emergency vehicle to roll over, police said.

The Allina ambulance was transferring a woman and her 3-year-old son from Cambridge Medical Center to Children’s Hospital Minneapolis when the crash happened around 9 p.m. at the intersection of Hwy. 65 and 109th Avenue, said Allina spokesman Tim Burke.

The child was taken to Children’s Hospital with no serious injuries. The mother was taken to Abbott Northwestern Hospital where she was checked and released, Burke said.

Two members of the ambulance crew were taken to Mercy Hospital in Coon Rapids where they were treated and released, he said.

A 17-year-old boy was making a left turn from northbound Hwy. 65 to westbound 109th Avenue when he struck the ambulance, which was headed south on Hwy. 65.

The teen had a red light and did not obey it, police said.

He was also treated for noncritical injuries.

Alcohol did not appear to be a factor. The teen will be charged with a misdemeanor, police said.
