documents: #Person1#: A report says running red lights causes one thousand traffic accidents every year.
  #Person2#: It's horrible. Why do drivers run a red light then?
  #Person1#: Maybe they know they shouldn't run a red light, but when they are driving they don't pay enough attention to traffic lights.
  #Person2#: Talking on the cell phone while driving is very dangerous too. It increases the chance of accidents.
