That means that if they are pulled over and have their breath tested, even if the result is only .01, they will be charged with underage drinking and driving. Vanessa’s law went into effect in 2004, one year after Vanessa Weiss was killed in a car accident when she was the passenger in a vehicle of an unlicensed 15 year old driver. Vanessa’s law bars individuals under the age of 18 from obtaining a driver’s license if they are in a crash related traffic violation, or if they receive a DWI/DUI or a DWI/DUI related offense (Open Bottle, Underage Drinking and Driving, etc..).
