Not necessarily. It seems from your next post that you see the same thing that I do. The story that I read a while back said that in a lot of cases, if a car leaves the road after 2 in the morning, it gets classified as 'alcohol related' EVEN if the BAC is ZERO. It may be that the driver fell asleep or was forced off the road by someone (of unknown sobriety), but the death gets marked as 'alcohol related'. There were other egregious examples of statistical BS. That article (I have to find it) brought the real toll down to about 30% from the reported 50%.
That would mean that 70% of the deaths are caused by people who are not under the influence of alcohol. Is there a 'Driving While Stupid' checkpoint coming to get these drivers off the road?
Sometimes it makes me wonder if there is another agenda at work.
