A first-of-its-kind national report reveals that 15.1 percent of the nation’s drivers age 18 and older drove under the influence of alcohol at least once in the past year.


The report says that in some states the levels are far higher — about one in four drivers.


Nationwide, an estimated 30.5 million people aged 12 or older drove under the influence of alcohol at least once in the past year according to the report by the Substance Abuse and Mental Health Services Administration.


Driving under the influence ranged from a low of 9.5 percent in Utah, to highs of 26.4 percent in Wisconsin, 24.9 percent in North Dakota and 23.5 percent in Minnesota.


West Virginia was had the second lowest rate at 10.1 percent, while Ohio fell just above the national average at 15.7 percent.


The report is based on the combined data from the 2004 to 2006 National Surveys on Drug Use and Health and provides state-level estimates for the pervasiveness of driving under the influence of alcohol and driving under the influence of illicit drugs.


These estimates are annual averages based on combined data collected from 127,283 current drivers surveyed in 2004, 2005 and 2006, the most recent data available.
