I was driving down the street with family when I looked out the window and saw a triangular object with lights flying over houses. I noticed it because it was right in my line of vision and perfectly visible. I had no idea what it was when I first saw it. It was black and triangular and had blue lights around the outside, and turned on its side while flying, and changed direction after a few minutes. I was very confused when seeing it, because as we got closer to it I thought there would be an explanation for what it was (that I'd discover it was just a sign or a reflection or something) but then I saw that it was just an object flying on its own accord, like a drone or something, except I googled pictures of drones and it doesn't match any that are used by the US government or google. I lost sight of the object as we drove beyond it, and I think it started flying away. When we drove back five minutes later it wasn't there anymore.
