A recent study conducted by the Centers for Disease Control and Prevention reveals that drinking and driving for high school teenagers has decreased by more than 50 percent in the last 20 years.

In 1991, high school students who were at least 16 years of age were surveyed to determine how often they got behind the wheel after consuming alcohol. The results of that study indicated that 22.3 percent of the students had drove under the influence of alcohol within 30 days of taking the survey.

More than two decades later, high school students were surveyed yet again by the CDC regarding their tendencies to drink alcohol and operate a motor vehicle. This time, the data indicated that 10.3 percent of the high school students admitted to drinking and driving within 30 days of the survey. This number is down by more than half since the initial survey was administered in 1991.
