The Scripps Howard News Services did an analysis of the fatal car accidents in Illinois for the years 1994-2008 and determined that for that time frame, one-third of the fatal traffic accidents in Cook County were the results of drunk driving car accidents. The numbers were actually higher in more rural counties where there is less public transportation, greater distances between places, and rural roadways.
The study underlines what we already know: that drinking and driving puts not only your own life at risk, but others in your vehicle and on the public highway.
