Respectful is always the key. I got out of a 'go to jail' ticket (100+ in a 75) by pulling over as safely as I could, shutting everything down and having paperwork ready. The sheriff asked me if I knew why he was stopping me and I said "yes, I did something stupid". He told me what he had me on radar for and I asked him if he wanted me to exit the vehicle. He said 'no, I'm only going to write you for 'basic speed'. It's a $185 ticket.' I said thank you. 15 minutes later, I'm on my way to Wichita. Now he flashes his lights and waves to me when I pass where he sets up.
