In Tennessee it’s polite to inform them but as soon as they run your license, they are going to know anyways.
IMO- it’s best to tell them upfront. Especially since my infraction was only a blown headlight.
I just handed the officer my permit with my license. He didn’t seem to care one way or another.
according to my legal class taught by a detective they know if you have a colorado chp. they run the plates, get the car registration name, then run a second database, unconnected to dmv, to determine if you have a permit. it is best to wait patiently with both hands on the steering wheel, no sudden moves and never use the word GUN.
