And make their jobs easier...
Every time I get pulled over (so I'm a bit of a speeder, what of it?), I make sure I do everything I can to cooperate. I park the truck (I've actually seen some people just hold their foot on the break. Really people?), turn on the inside lights, turn off the truck, and keep my hands on the steering wheel. I'm not fishing around for my insurance or registration or license... I want the officer to be able to see my hands at all times. When they ask me if I know why they pulled me over, I cop to it. When they ask for my documentation, I tell them where I will be reaching BEFORE I reach there, and I move slowly enough so that there is no confusion or question as to what I'm doing. It's always yes Sir and no Sir (or Ma'am). If I have a question, I always ask it in a respectful manner. I try my best not to act put out by the experience.
I find, that the more cooperative I am, the more understanding they tend to be.
Whatever the outcome, at the end of the encounter I'm sure to shake their hand and thank them for their service.
