Those aren't exactly codes, in the sense of a "Code 99" They are as noted above, abbreviations. A "V&T stop" means someone was pulled over for a violation of Vehicle and traffic Law. The officer will run a DLIC, most of the time by client ID. Or check your drivers license by the 9 digit ID on the front.
In general most places including Oneida Co. have gone to plain english for most things. There are only a handful of situations where they prefer to use a code. Most of what you hear is short hand, abbreviations or direct references to laws and rules, such as a MHL 941 or 1192 (DWI)
There are some other "leftover" terms such as RALL and Rolling Data that refer to previous computer systems, but are essentially license and registration checks.
For beginning listeners reading this post...it is a lot more common sense than you think. Don't make more out of it than it is.
