No, it does not outright ban shooting at vehicles. We have a very detailed policy regarding shooting both at or from a moving vehicle.
Policy 300.4.1 states, “Shots fired at or from a moving vehicle are rarely effective. Officers should move out of the path of an approaching vehicle instead of discharging their firearm at the vehicle or any of its occupants. An officer should only discharge a firearm at a moving vehicle or its occupants when the officer reasonably believes there are no other reasonable means available to avert the threat of the vehicle, or if deadly force other than the vehicle is directed at the officer or others. Officers should not shoot at any part of a vehicle in an attempt to disable the vehicle."
