MADISON, Maine — A Skowhegan woman had a seizure while driving Friday morning on White School House Road, causing her 2000 Chevrolet SUV to go off the road, through a snowbank and hit a tree, police said.

Daisy Mack, 32, was not injured but was sent to Redington-Fairview General Hospital in Skowhegan for observation, said Madison police Sgt. David Trask.

Mack’s two passengers, her 5-year-old son, Sky Martin, and friend Misty Witham, 21, were not injured, Trask said.

Trask said that Mack was driving less than a mile from the U.S. Route 201 intersection when her seizure began. Trask said he did not know the nature of the seizure.

When the SUV started veering off the road, Trask said, Witham tried to control the steering wheel from the passenger’s seat, but could not. The vehicle went through deep snow and then hit the tree, Trask said.

“The snow really absorbed quite a bit of the speed,” Trask said. “It was pretty deep. They had a hard time getting the door open.”

All three people were wearing seat belts, Trask said.
