Drunk driving risk factors
Even at an Alcohol Content (AC) level as low as 0.04%, alcohol in your blood system affects driving ability and crash likelihood, according to Special Report 216, "Zero Alcohol" by the Transportation Research Board.
- The probability of a crash begins to increase significantly at 0.05 AC and climbs rapidly after about 0.08%.
- For drivers with AC's above 0.15% on weekend nights, the likelihood of being killed in a single-vehicle crash is higher than it is for non-drinking drivers.
Alcohol-related crashes in Wisconsin are much more likely to involve men than women.
- Among fatally injured male drivers in the year 2012, 34% of those tested had AC's of 0.08% or more and women tested for .08 or above were 19%. These numbers are taken from all of the fatalities that were tested.
- Men, ages 21-24, are the most likely drivers to be killed in a crash when their blood alcohol content is above 0.08.
Male drivers ages 21-40 make up the majority of fatally injured drivers with high AC's. This group has shown only a modest decline in the 1980s in the percentage of fatally injured drivers with high ACs.
In contrast, other age groups, particularly teenagers, show substantial declines. Drivers in the 16-20 year-old group showed the biggest improvement throughout the 1980s, due largely to the 21-year-old alcohol purchase laws.
