Final answer:
Under 'zero tolerance', the consequences for an underage driver vary depending on the jurisdiction. In some cases, an underage driver may lose their license immediately upon being caught driving under the influence of alcohol.
Step-by-step explanation:
Under 'zero tolerance', the consequences for an underage driver can vary depending on the jurisdiction. In some cases, an underage driver may lose their license immediately upon being caught driving under the influence of alcohol. Other jurisdictions may have a tiered system where the consequences become more severe with subsequent offenses.
For example, in New York State, a driver under the age of 21 who is found to have a BAC of 0.02% or higher can have their driver's license revoked for at least 6 months. If it is their second offense, their license can be revoked for at least 1 year, and for a third offense, the revocation can be for at least 1 year or until they turn 21, whichever is longer.
It is important to note that the specific consequences for an underage driver losing their license may vary depending on the laws of the jurisdiction they are in. I recommend checking with your local Department of Motor Vehicles or a legal professional for the most accurate and up-to-date information.
