Seventeen people were injured and taken to hospitals Saturday night after a collision between a bus and a car near Baltimore Washington International Thurgood Marshall airport, authorities said.

The bus left the roadway, crashed through a guardrail and ended up in the woods, said Capt. Russ Davies, a spokesman for the Anne Arundel County fire department. The crash occurred about 8:40 p.m. near Dorsey Road and Shipley Avenue.

Davies said most injuries were minor, but two occupants of the car were taken to the Maryland Shock Trauma Center, with possibly serious injuries.

One was a 17-year-old male and the other was a 20-year-old woman, he said.

Davies said six people from the bus declined to be taken to the hospital.

The cause of the crash was not known immediately. The bus involved appeared to belong to the Regional Transportation Administration, which serves central Maryland, including Howard County, Anne Arundel County, the city of Laurel and northern Prince George's County.
