After more than 20 years of warnings about the dangers of drinking and driving, Mothers Against Drunk Driving says too many Americans are still hitting the road after drinking.
Wendy Hamilton says people have stopped listening because they think the drunk driving problem has been solved. Hamilton says 46 percent of the people who will be killed on the nation's highways this holiday weekend will die in alcohol-related wrecks that she says are completely preventable.
MADD says 16,000 people die each year because of drunken drivers, and more than a-half-million people are injured.
