There really easy to learn. This is the beta version of it if it seems like there hindering us then we will take them out.
CODE 1: Non-emergency response. No lights or siren, following the flow of traffic.
CODE 2: Non-life-threatening emergency response. No use of emergency lights or siren. Must follow all traffic laws.
CODE 3: Life-threat response. Emergency traffic, or simultaneous use of lights and siren required in order to achieve a rapid response. This does allow the responding unit to ignore jurisdictional traffic laws, but does not allow the responding unit to operate without due regard to safety.
CODE 4: All clear or I am okay. Also used to tell another unit they can disregard.
CODE 5: Area under surveillance. All marked units stay out of area.
CODE 6: Calling for a cover unit(s).

CODE 0: Big emergency. All units in the area respond code 3 to the units' location.
