This choropleth map shows data on driving deaths in the USA from 2008 to 2012 on county level. By default you see the percentage of motor vehicle crash deaths with alcohol involvement.
Motor vehicle crashes are often used as a proxy for excessive alcohol use due to the burden of injury possible through impaired driving. The percentage of motor vehicle crash deaths with alcohol involvement directly measures the relationship between alcohol and motor vehicle crash deaths.

On the map you see some counties with a 100% rate of alcohol-impaired driving deaths, those have low numbers of total driving deaths though. Grant and Ransom Count for example had 1 driving death each from 2008 to 2012.
The data was downloaded from County Health Rankings (XLS file).
