The driver of the tractor-trailer was taken to hospital with minor injuries. The driver of the vehicle that slammed into the police car also suffered minor injuries.
The police officer in the cruiser was not injured.
The express lanes at Port Union Road were closed for the investigation but reopened at 7 a.m.
