Drunken driving has fallen substantially in recent years, a government reported note Wednesday, even as 11,000 crash fatalities took place, about a third of the national total took place.

Alcohol-impaired driving fell 30 percent from 2006 to 2010, according to the report, the Centers for Disease Control said on October 5. Self-reported episodes were down from 161 million in 2006 to 112 million in 2010.

Men accounted for 81 percent of all episodes.

The survey defined alcohol-impaired driving as driving “when you’ve had perhaps too much to drink” in the past 30 days.

The CDC analyzed data from a 2010 survey of behavioral risk factors.

The survey contained information on prevalence, episodes and rates of alcohol-impared driving among U.S. adults at least 18 years of age.
