Nationally, 12.8% of all drivers involved in fatal collisions during 2013 are known to have been intoxicated according to the blood alcohol concentration (BAC laws) of their state.
[citation needed] This number is based on a systematic examination of the official records of each and every incident involving a fatality during that year in the US.
The higher number (about 40%) commonly reported refers to collisions defined as alcohol-related as estimated by the National Highway Traffic Safety Administration.
Each year, The Century Council, a national non-profit organization funded by a group of alcohol manufacturers, compiles a document of alcohol-related traffic fatalities.
In 2016, in the USA, 10,497 people were killed in crashes involving alcohol-impaired drivers; this represents 28 percent of all traffic-related fatalities.
