A lone runner on the road at 3 a.m., crossing an intersection against the traffic light, and wearing headphones.  In fact, her friends say that she always wore headphones and frequently ran at this time of night.  The news articles do not indicate whether she wore a flashing vest, but the semi truck did not even know he had hit her, so she was likely not wearing highly visible clothing.  Please runners, you must take care of yourselves - drivers will not see you.  You need to be vigilant in your ability to see and hear what is happening, when you share the road with vehicles.
