Motor Carrier Inspectors?

[ScannermanHFX]

Does anyone have details of what talkgroup on the MPSRN motor carrier inspectors use? I found the vehicle compliance talkgroups, and I'm wondering if they all use the same set of talkgroups. For greater clarity, I'm looking for the guys in Dodge Chargers who inspect buses. Vehicle compliance are usually in pickup trucks, and after non bus commercial vehicles for inspections and the like.

I believe they operate on the vehicle compliance talkgroups. Over last couple months I've noticed units are getting new call signs. Haven't the Motor Carries call signs (MC-#) in a while.

So you think they probably communicate with a different call sign than is marked on their car? Any easy way to tell whether or not a specific call sign is compliance or carrier inspector?

All seem to be using "VT-#" as call sign.
