Although drunk driving fatalities in the United States have been reduced by nearly 50% since the early 1980s, thanks to harsher penalties for DUI’s and the work of awareness groups like MADD , alcohol-impaired driving remains a serious problem on America’s roadways.

In 2018, 29% of total motor vehicle fatalities were a result of alcohol impairment, wherein an operator of a vehicle involved in the crash had a blood alcohol concentration of .08 or greater. The good news is that this is the lowest percentage of alcohol-related fatalities since the NHTSA began reporting alcohol data in 1982. However, the rate is much higher in some states compared to others.

To give you a full picture of the current drunk driving situation in the U.S., we used the latest FBI arrest figures , National Highway Traffic Safety Administration statistics on fatal motor vehicle crashes, and U.S. Census data to rank all 50 states based on the severity of their DUI problem.

We calculated ourusing each state’s DUI arrest rate per 100,000 population and the DUI fatality rate per 100,000 population. View the results in the heat map, below
