I had to close up the entire east side of the house, a few minutes ago, due to an idling diesel rig blessing us with it's effluvium. I finally walked out there to find a tractor/trailer rig with a police escort attempting to turn around. Our house is at the butt end of the street. My wife told me she sat behind a different effort, on a different day. I guess they just have to get as close as they can. Or perhaps they use it as a training exercise.
