What can be done about illegally parked vehicles, such as those blocking a driveway?

Contact the Parking Violations Bureau, Department of Transportation, at 213-485-4184, and an officer will be dispatched. If the person who reported the illegally parked vehicle lives at the location, goes out to meet the officer, and explains to them that he or she lives at the location and cannot leave the driveway due to its being blocked, the officer can impound the vehicle.
