Thats why i try to detour .. When ever possible
Not a wise idea! Whenever GA DOT did inspections on I-20, they'd always let us county and local cops know so wed set up on the back roads looking for guys such as yourself. When we did roadside checks, we always set up chase cars on opposite ends of the checkpoints looking for cars to make a u-turn etc.
I don't believe the DOT whether they're state or federal use contractors. As far as "plain clothes" DOT.....the Feds some wear jumpsuits the guys in plain clothes do the audits at the carrier level but can pull a truck over. They don't carry badges but carry the two sided federal credentials like other federal agencies carry!
