As far as brushes with law enforcement as a former police officer the best way to not get pulled over is to well not give them a reason. As far as the search question. You have the right to say no, most of the time we won't ask unless there is something suspicious. If we think you are hiding something ang still say no. We will have the drug dog do a walk around the car. That will take a long time. So if you don't mind 45min-90 min for a traffic stop say no. Howe er if you wish to be on your way just agree. However most of the time you won't be asked
Yep, just comply.
