White Marsh, Md. ? At least 86 vehicles crashed in 11 separate accidents on Interstate 95 Saturday, a string of collisions apparently triggered by sunlight shining off sleet that had just been dumped by a fast-moving storm.

At least 49 people were injured, some seriously, but no deaths were reported in the crashes along an 11-mile stretch of I-95 in suburban Baltimore.

The accidents started happening about 4:30 p.m. after hail and rain fell on the highway.

Cindy James, of Woodbridge Va., said the road wasn’t slippery but the glare was unusually strong from sleet on the road, even while wearing sunglasses.

“Everybody stopped because of the glare and the sleet,” said James’ 15-year-old daughter, Veronica.

Susan Whickers, of Baltimore, said she knew she was in trouble when drivers in all four lanes slammed on their brakes.

“I was thinking, ‘Oh God,’ because the car in front of us went right under a tractor-trailer,” Whickers said.

Leslie Baker, an emergency medical technician with the Joppa Magnolia Volunteer Fire Company, said she knew of 49 people who had been injured, including 22 in one crash involving a bus with 30 people aboard.

Five people being treated at the University of Maryland Shock Trauma Center were in serious condition.
