Drugged and drunk driving is a significant problem in the United States. It's also a dangerous issue for underage drivers. While adults are more likely to drive drunk, underage persons are more likely to have alcohol-related car accidents.
In fact, the National Highway Traffic Safety Administration (NHTSA) reports that auto accidents are the leading cause of death for U.S. teenagers. In over one-third of these accidents, alcohol is a factor.
To combat the problem, states have enacted strict underage drinking laws. These laws include setting more stringent underage blood alcohol content (BAC) limits and criminal penalties for driving under the influence of alcohol (DUI). The following table details the underage DUI and DWI laws for each state.

Zero Tolerance Laws for Underage DUIs
All states have enacted zero tolerance laws for underage DUIs. Zero tolerance means that anyone under 21 will face arrest if caught driving with any detectable amount of alcohol or drugs in their system. Each state has its own per se legal limit for minors. A per se limit is the blood alcohol content (BAC) level that triggers a DUI arrest.
This per se limit for underage drivers varies by state but is between 0.0% and 0.02%. It only takes a small amount of alcohol to reach a 0.02% BAC. The average teenager can be over this amount with one alcoholic drink.
Implied Consent Law
When an officer asks you to submit to chemical tests, there is an expectation that you comply. State laws have enacted implied consent laws as part of your driving privileges. When you earn a driver's license, you agree to obey the law. Cooperating with chemical tests is part of this agreement.
You may decline chemical tests. You are within your right to say no. Yet there are penalties. Usually, the officer will suspend your driver's license at the time of your refusal. You may receive a fine. The department of motor vehicles (DMV) can require you to attend alcohol education classes before you can get your privileges back. Plus, refusing chemical tests will not prevent your arrest. Law enforcement can use your refusal in court.
Underage DUI Charges
Law enforcement charges DUIs based on your blood alcohol level. When you're stopped on suspicion of DUI, or if you are in an accident in which alcohol use was involved, a police officer will ask you to submit to field sobriety tests and chemical tests. While field sobriety tests can show impairment, a chemical test will determine your BAC and whether you may have taken other intoxicants. Chemical tests can consist of a Breathalyzer or breath test, a blood test, or urine analysis.
If your BAC registers below 0.07%, you face an underage DUI. If you are under the age of 18, these charges will go through your state's juvenile or family court. However, a BAC of 0.08% or more (or 0.05% in Utah) will earn you an adult-level DUI case. These are typically misdemeanor charges, unless your BAC is very high, or you have caused serious property damage, injuries, or death.
DUI Penalties
A DUI conviction comes with stiff penalties. Even as a minor, you may have to pay a lot in fines and court costs. You will lose your driver's license for a while. If your BAC is very high, you may lose your license until you reach 21.
In addition, you will likely need to attend substance abuse education classes.
Many states do allow minors to apply for a restricted license so they may drive to school and other limited places. You will likely have to install an ignition interlock device (IID) for this license. An IID is linked to your vehicle's ignition. You must breathe into the device before you can start your car. If it detects any alcohol, it will not allow the engine to engage.
