About ten or fifteen years ago I was driving to the range, and had my AR-15 in the hatchback, covered with a blanket. There was road construction on the highway, and there were cones separating two lanes of the highway. I wasn't aware that it was a traffic violation to change lanes where there are those cones put out, and they were spread out quite a bit, so it was no trouble to switch lanes when my lane came nearly to a stop, and the other lane was moving a bit faster. I saw the cop there, but didn't know it was a violation (honestly), so I did it. He waved me over, and told me it was a violation to do that, and that I was getting a ticket. He looked in the back of my car, and I guess the car's movement caused the blanket to move off the AR a little, and he asked if I had (and these are the exact words he used) an Assault Weapon back there. I said, "No, it's an AR-15." He said, "A what?" I told him again. He told me to stay put, he'd have to call this one in. I waited while he went to his car and spoke to someone (I guess his supervisor) for about 15 minutes. He comes back and asks me why I have the rifle (no longer calling it an Assault Weapon), and I tell him I'm going to the range to shoot it. At that, he gave me my ticket, and that was that, but what a hastle! Good thing I didn't bring the number of various weapons I usually bring to the range.
