A motorist was seriously injured Tuesday when a deer crashed through his windshield on a road in Prince George’s County, authorities said.

The collision occurred about 2 p.m. on Indian Head Highway and Pine Lane, in the Accokeek area of the county, said Cpl. Clinton Copeland, a spokesman for the county police.

The collision exemplified a type of highway incident that has become an increasing concern to drivers in the Washington area and nationwide.

According to Copeland’s account, the deer darted in front of the vehicle, shattering the windshield. The driver was taken to a hospital with what were believed to be serious injuries. The deer apparently was killed.

Indian Head Highway, or Route 210, is a major thoroughfare in southwestern Prince George’s. At the site of the accident, it is divided by a grass median and bordered on both sides by trees.

The presence of deer throughout the metropolitan area has prompted controversy, particularly over efforts to reduce the size of populations in parks. The animals are blamed for damaging plants and young trees.

One woman who lives near the site of the collision said deer are common there.

“In fact,” she said, “they eat all my flowers.”

In recent years, she said, the area has become increasingly developed. But in the past, she added, it “was not unusual to see eight in your yard.”

Statistics provided by an insurance company projected that more than 1.1 million collisions in the United States between cars and deer would occur in the year beginning July 1, 2010.

The statistics indicated that 34,000 such collisions would occur in Maryland in that period.

The number forecast for the District was about 370.
