More than 30 million Americans will hit the road this Labor Day weekend for one last summer road trip. But a new survey indicates many of those drivers admit they may be driving while under the influence of alcohol.

One in 12 American adults admit they may have driven while drunk within the last year, according to a new survey by FindLaw.com (http://www.findlaw.com/), the most popular legal information website. The survey found that 7 percent of American adults say they have driven within the last 12 months even though they thought they may have been over the legal blood alcohol limit for drinking and driving in their state.

Problem parents -- those who fail to monitor their children's school night activities, safeguard their prescription drugs, address the problem of drugs in their children's schools, and set good examples -- increase the risk that their 12- to 17-year-old children will smoke, drink, and use illegal and prescription drugs, according to the National Survey of American Attitudes on Substance Abuse XIII: Teens and Parents, the 13th annual back-to-school survey conducted by The National Center on Addiction and Substance Abuse (CASA) at Columbia University.

"This year's survey reveals that too many mothers and fathers are problem parents who fail to take essential steps to prevent their kids from smoking, drinking or using drugs. By their actions -- and inactions -- by failing to become part of the solution, these parents become part of the problem of teen alcohol and drug abuse," said Joseph A. Califano, Jr., CASA's chairman and president and former U.S. Secretary of Health, Education, and Welfare. "Indeed, these problem parents enable -- some even encourage -- their 12- to 17-year-olds to use and abuse tobacco, alcohol, and illegal and prescription drugs."
