I have a valid reason if I were to be asked that lol. I was for a DUI checkpoint not too long ago and when I told him some information, the officer was kinda left stumped as to what to do with me. I ended up with the most basic of field tests and was on my way in no time. If I have a absolutely solid answer to such questions, I will answer them...because if called out and I have enough to back my side up, it won't end well for the officer.
