A driver in Anne Arundel County remains in critical condition after his car veered off the road and struck a concrete retaining wall early Saturday.

The collision happened shortly before 2 a.m. on Catherine Avenue, near Harlem Avenue, in Pasadena.

When police officers responded to the scene, they found the driver, a 29-year-old Severna Park man, outside the car.

The car was badly damaged and the driver appeared seriously injured, police said.

The driver was taken to the University of Maryland Shock Trauma Center for treatment. Police did not have details about his injuries but said they are potentially life-threatening.

There were no other victims, and no other vehicles were involved in the crash.

The cause of the crash remains under investigation, but it appears that speed was a contributing factor, police said. It has not been determined whether the driver was intoxicated at the time of the crash.
