Study suggests drunk driving happens more frequent than reported

An alarming new study shows more than 4 million people admit to driving while drunk.
That's according to a study from the Atlanta-based Centers for Disease Control and Prevention.
The adults surveyed reported that they've driven while intoxicated at least once in the last 30 days.
The study also shows two-thirds have been involved in a drunk driving incident.
Men 21 to 34 years old were the most likely to drink and drive.
