Zero tolerance laws are even tougher on underage drunk drivers. Young adults, under 21 years of age, can lose their license for a full year. If a person under age 21 is tested and found to be over the legal limit of 0.08, he can be arrested, convicted of drunk driving and tried as an adult.
If a drinking driver’s BAC is over the legal limit of 0.08, his driver’s license may be suspended or revoked for anywhere from a week to years. Vehicle sanctions may require the offender’s car include a specially marked license plate or even an interlock device that prevents the car from starting unless the driver passes a breath scan test. The car may even be impounded, confiscated, or sold.
