An estimated 17 million motorists may have driven while drunk in the preceding 12 months, according to a report U.S. regulators released as part of a crackdown tied to travel during the U.S. Labor Day holiday.
Eight percent of almost 7,000 U.S. drivers ages 16 and older responding to a 2008 National Highway Traffic Safety Administration telephone survey said they had driven when their blood-alcohol content was above the legal limit at least once in the previous year.
