The purpose of this Department Notice is to provide guidance to officers when circumstances arise which necessitate the preemptive deployment of tire deflation devices (TDD).
TDD uses a variety of mechanical methods to defeat the integrity of vehicle tires to release the air pressure in a predictable, controlled manner.
TDD are de-escalation tools and are intended as a defensive vehicle intervention tactic, deployed with the intent to afford time and distance by safely slowing a vehicle, thus reducing risk to the public, vehicle occupants, and officers.
