I was pulled over for my wiper blade blocking my registration sticker. The officer then continued to check against the license plate, vin, then moved on to the inspection sticker. Going as far to inspect the signature on the inspection sticker and that is was in one piece which required me to leave the vehicle and stand at the front. Then he started questioning me about my muffler which is in the mid high 90's db range. Fortunately, I was pulled over in a rural area and the sound wasn't too much of an issue. Although he did say "it was making my truck vibrate". I couldn't help but laugh.
