Fewer teenagers are drinking and driving according to a new report from the centers for disease control.
The report finds a 54 percent decrease since 1991.
In 2011 the vast majority of high school teens 9 in 10 say they did not drive after consuming alcohol. Researchers attribute the decrease in part to underage drinking laws and graduated drivers license laws.

Still nearly 1 million teenagers engage in drinking and driving, according to that same report.
It also says high school boys over age 18 were most likely to drive drunk.
