Buzz kills: No amount of alcohol safe to drive
“Accidents are 36.6 percent more severe even when alcohol was barely detectable in a driver’s blood,” Phillips said. Even with a BAC of 0.01, Phillips and Brewer write, there are 4.33 serious injuries for every non-serious injury versus 3.17 for sober drivers.
There are at least three mechanisms that help to explain this finding, Phillips said: “Compared with sober drivers, buzzed drivers are more likely to speed, more likely to be improperly seat-belted and more likely to drive the striking vehicle, all of which are associated with greater severity.”
There also seems to be a strong “dose-response” relationship between all these factors, the authors write: The greater the blood-alcohol content, the greater the average speed of the driver and the greater the severity of the accident, for example.
The findings persist even when such potentially confounding variables as inattention and fatigue are excluded from the analysis.”
