Years ago there was a unit designation of VI was wondering if that was for the vehicle inspection group of the Idot since it was back in the late 70s early 80s since I do not remember ISP having V cars at that time they were also on low band

Dist. 15 also uses the "Car" designation from time-to-time rather than everyone saying "15-" - not to be confused with "Car" from ISP Director's Office :) When D15 cars are on other talkgroups they'll use the "15-" identifier

D15 is in there own little world. Since they are self funded.

After I got to remembering ( I was a teenager now in my 60s) the state police took it over from idot for a couple of years then gave it back
