Multiple lanes of Route 100 in Howard County were closed Friday midday as police investigate a three-car collision involving an officer, police said.
Nobody was seriously injured in the accident, police said, which occurred around 11 a.m. in the right shoulder of the westbound side of Route 100 shortly before the Snowden River Parkway.
The incident began when an officer stopped a Volkswagen Jetta on the side of the highway, police said. During the traffic stop, a Cadillac Escalade rammed into the back of the patrol car while the officer was inside, which pushed it into the Volkswagen.
Police say they do not know why the Escalade struck the patrol car.
The driver of the Escalade was a 31-year-old man from Baltimore. He was taken to the University of Maryland Shock Trauma Center with non-life threatening injuries.
The police officer, whose injuries also were not life threatening, was taken to Howard County General Hospital.
The driver of the Volkswagen was a 31-year-old man from Linthicum heights. He was not injured.
She said it's unclear if the driver of the Cadillac will face charges related to the crash.
