Seniors over the age of 70 have long been associated with unsafe driving, with death rates steadily increasing as more elderly hit the road. At least that's what we thought. A new study by IIHS shows that the death rate of elderly drivers has declined by 21 during that time. Time behind the wheel has increased as well, with seniors logging far more miles than they have in the past. Some reasons for the decline include healthier, more fit seniors and safer drivers. State governments have also been more diligent in getting unfit seniors off the road with regular skills tests. One study shows that seniors are increasingly aware of the dangers of driving, and limiting drive time at night and on the interstate.
