Four people were taken to hospitals Sunday after a car ran into a Metrobus in Prince George’s County. The crash was at least the second this weekend involving Metro in which people were taken to hospitals.

In Sunday’s incident, the bus, on the K 12 route, was at a bus stop at Hil-Mar Drive and Walters Lane about 4 p.m. when it was struck by a car from behind, said Metro spokesman Dan Stessel. The site is in the Suitland/Silver Hill/Forestville area.

Although no injuries were reported at first, he said, four passengers said later that they had been hurt.

County police ticketed the driver of the car for operating without a license, Stessel said.

On Saturday, 15 people were taken to hospitals following a collision that occurred in the 2700 block of Martin Luther King Jr., Avenue SE, authorities said. They said the collision, involving an A6 bus, occurred when a minivan tried to turn in front of the bus. The minivan operator was ticketed by D.C. police for an improper lane change, Stessel said.

All injuries were described as minor by Lon Walls, a spokesman for the D.C. fire department.
