Having been a truck driver and have a brother-in-law who is a retired police captain. I have adopted some practical experience when dealing with police. Especially at night. When ever possible I opt to go into a shopping center parking lot or a gas station. If not easy to get to one I opt for under a street light. I turn on all my inside dome lights put on flashers and turn the engine completely off. I roll down the window about 4-6 inches and keep my hands on top of the steering wheel. remember never take off seat belt till officer instructs you to exit vehicle. As far as CC goes this advice in the video is very good. In Texas it is mandatory to inform the officer that you have a CHL, and that you are carrying it at the moment.
