Okay, confession time (I'm fairly embarrassed to admit this)...one time many years ago I was going under an overpass. There was a row of three lights. One in front of the overpass, one behind and another a half block beyond the overpass. I looked up and saw the first row of lights were green and assumed they were all green. In my defense the second row of lights were partially hidden on the other side of the overpass. I was going at a pretty good pace maybe 23 mph and heard "Stop!" To this day I'm not sure if someone yelled that from the street or it was in my head. Anyways the second row of lights were red. I had a half second to decide to lay my bike down or get splattered in the front of the car. I did a controlled crash and my front tire put a big dent in their door. The car owners and their insurance company were pretty nice about it. Wound up costing me $500 to repair the door. Small price for a lesson learned...pay attention, don't assume!!!
