The National Highway Traffic Safety Administration (NHTSA) and law enforcement agencies across the country practice a "zero tolerance" policy toward underage drivers and alcohol.

The zero tolerance policy ensures that if underage drivers possess a blood alcohol concentration (BAC) level over .00 percent, they will be found guilty of impaired driving.

Research has shown that young impaired drivers are involved in fatal crashes at approximately twice the rate of adult drivers over the age of 21.

Since 35 percent of all fatal crashes for underage drivers involve alcohol, it is imperative that young adults understand that zero tolerance laws are not meant to single out or punish young adults in particular, but rather to safeguard them against unsafe driving behaviors that threaten their well-being.

Zero tolerance laws provide different policies regarding drivers under the age of 21. Studies show that more 18 and 19 year-olds die in alcohol-related crashes involving low BAC levels than any other group.

By encouraging safer driving habits at a younger age, NHTSA hopes to promote healthier driving behavior for the future.
