Just for clarification, these guys are the Dept. of Motor Vehicles enforcement, which can pull anyone over, not just cmv's. I have heard them in the past initiate a pursuit on 95 in Waterford years ago, and came up on 42.040 with Troop E. I believe the inspectors do have to attend some police academy time because they have to qualify with a sidearm to be in the cruiser. Don't confuse them with the CSP truck squad, whose primary function is commercial vehicle enforcement, responding to accidents involving cmv's, etc. They are the ones we hear on the "admin" & "traffic" talkgroups. Also, I like how the DMV cruiser lightbars now have "motor vehicle" in the middle. Two seperate agencies here.
