Under New Jersey’s zero-tolerance laws, it is considered a criminal driving under the influence (DUI) offense for drivers under the age of 21 to drive with any detectable amount of alcohol in the bloodstream -- a blood alcohol concentration (BAC) of .01 or more. A conviction brings penalties that include a 30-90 day loss of driving privileges or a postponement of driving privileges, community service for a period of 15 to 30 days, and mandatory participation in an alcohol and traffic safety education program.
