Was stationed in Wash, DC in a USCG safety program and talking to other DOT safety professionals whom I had no reason to doubt.
I had the ability to acquire and document and publish US Govt. stats. as did many colleagues working in US DOD safety programs.
There were many irregularities that we studied within the safety statistics documented through the years.
https://en.wikipedia.org/wiki/Alcoh... United,estimated BAC of 0.01 g/dl or above.
Alcohol-related traffic crashes are defined by the United States National Highway Traffic Safety Administration (NHTSA) as alcohol-related if either a driver or a non-motorist had a measurable or estimated BAC of 0.01 g/dl or above.
This statistic includes any and all vehicular (including bicycle and motorcycle) accidents in which any alcohol has been consumed, or
believed to have been consumed, by the driver,
a passenger or a pedestrian associated with the accident.
Another well believed theory when I was there was that even though a lot of accidents were labeled as "alcohol related" the true cause of the accident was fatigues as they typically happened between midnight and dawn. I am very wary of "safety statistic" as most come with agendas.
