This is something I couldn't bring up at the meeting due to the size of the suggestion. I know that the senior staff is against most forms of codes and the like in favor of plain-speech. I believe that this system will improve communication during vehicle pursuits as well as keeping radio traffic mostly clear in favor of pursuit-related call-outs.
I am proposing three "levels" of pursuit, each signifying what precautions must be taken during a pursuit, what the suspect has done, and what all the officers are permitted to do during the chase. The suspect may escalate the pursuit code as he continues in the pursuit. The levels are as follows:

CODE GREEN: This is the level that most pursuits will begin at. The suspect is evading arrest, but has not posed a danger to the general populace. They are speeding and disobeying traffic devices, but otherwise acting in a (relatively) safe manner. In a Code Green pursuit, you are to follow the suspect until they give up, crash out, or run out of fuel. The suspect has not behaved in a manner in which an evasive maneuver is warranted.

CODE AMBER: The suspect is behaving in a manner that poses a threat to the officers involved as well as the general populace. They are swerving, driving in opposite lanes of travel, driving on sidewalks, or otherwise behaving in an unpredictable and reckless manner. During a Code Amber pursuit, officers are allowed to perform pit maneuvers, place spike strips, and engage in other advanced maneuvers to disable the suspect's vehicle and apprehend them. If a suspect has been fleeing for an excessive amount of time, the pursuit may be upgraded to Code Amber from Code Green at the discretion of the highest ranking officer currently involved in the pursuit. Due to the nature of this code, motorcycles may not be classified as Code Amber, due to excessive risk to the suspect's life.

CODE RED: The suspect has behaved in a manner in which human life was harmed or taken. This includes shooting a civilian or running them over with their vehicle. During a Code Red pursuit, lethal force is authorized (given proper initiation) and the suspect must be apprehended in whatever manner possible without causing undue harm to civilian life.
