Most agencies just use plain speech for non-universal radio traffic, such as 10-999. RoN Takes place in fictional LA (LS) so I'd recommend using LAPD based 10-codes, 11-codes, and Codes (i.e Code 6= Investigating in Cali). Or, if you'd prefer plain speak as many do you can simply do that.

Also, 10-99 is the code for Emergency traffic/Urgent radio traffic such as Officer Down in most US areas. 10-0 Means shots fired in a couple states, but for the most part cops use plain speak. Have a good night my dear immersionists.

damn 10-999 is a mouthful for how often it happens in game lol

Appreciate the guide, I'll gladly use these with the fellas to make sure I'm not the radio jammer.

10-22 disregard is very useful; also I think negative is 10-74

Okay thanks

I think 10-10 means Negative, which could also be useful

Yeah, I mean, gun/firearm - meaning there's a hostile near. That usually means to send backup, but I'll update it.

10-32 is normally used as a request for additional units in most of the US.

That's true, but these are overall the most common

Every agency has different 10 codes
