A law enforcement officer shall not:
A. discharge a firearm into a fleeing motor vehicle unless such discharge is necessary to prevent an imminent threat of death or serious bodily injury to an officer or another person and the officer has no reasonable alternative course of action to prevent death or serious bodily injury; provided that when possible, an officer threatened by an oncoming motor vehicle shall move out of its path instead of discharging a firearm at it or any of its occupants; or
B. use a vascular neck restraint, unless a person's attack poses a threat of imminent harm to the officer or another person; provided that an officer shall cease the use of a vascular neck restraint as soon as the person no longer poses a threat of imminent harm to the officer or another person.
