Can You Get a DUI if You’re Under 21?
Driving under the influence is illegal in all 50 states, and so is drinking under the age of 21. Underage drivers caught drinking and driving are breaking multiple laws, leading to harsh legal consequences, and dangerous results.
- According to the Centers for Disease Control and Prevention (CDC), underage drinking causes about 4,300 deaths each year.
- The National Highway Traffic Safety Administration (NHTSA) reports car crashes are a leading cause of death for teens, and alcohol makes that risk even worse.
- In 2023, NHTSA data indicated 30% of drivers aged 15–20 who were killed in crashes had some alcohol in their system.
So yes, you can find yourself in a dangerous situation if you drink and drive as a minor, and you can get a DUI if you’re under 21.
Is There a Legal Alcohol Limit for Underage Drivers?
In many states, the legal blood alcohol content (BAC) limit for a DUI under 21 is set according to zero tolerance laws.
Zero-tolerance laws are specifically designed for underage drivers, with most states enforcing much lower BAC limits for anyone under 21. While the standard legal BAC limit for drivers over 21 is 0.08%, underage drivers can face penalties with BAC levels as low as 0.02%, or even 0.01% in some states.
Zero Tolerance Laws Explained
Most states adopted zero tolerance DUI laws to discourage any drinking and driving among people under 21. The presence of even a small amount of alcohol in an underage driver’s system can lead to major legal trouble. According to NHTSA, zero-tolerance laws are effective in reducing underage drinking and driving incidents and related fatalities.
Zero tolerance laws usually carry shorter, mandatory license suspensions for lower BAC levels.
Penalties for DUI Under 21
If you’re dealing with your first DUI under 21, the rules can vary depending on where you live. The consequences you face might change based on how much alcohol was in your system; whether your BAC was just over your state’s zero-tolerance limit or closer to the regular adult limit of 0.08%.
In some states, courts may focus on rehabilitation more than punishment. In other cases, the courts may order license suspension, license revocation, or jail time.
Here are some underage DUI penalties you might encounter:
- Fines: Most underage DUI convictions involve a financial penalty.
- Community service: Many judges see community service as a positive way to make amends.
- Mandatory courses: Alcohol education or treatment programs may be required.
- Probation: You might have regular check-ins with a court officer.
- Possible jail time: This can happen in some states, but many first-time offenders avoid it if your BAC was relatively low.
Will You Lose Your License After an Underage DUI?
If you’re charged with an underage DUI, there’s a good chance you’ll face a DUI under 21 license suspension, typically between 30 days and three years.
Some states suspend an underage driver’s license automatically, even if it’s the first offense. Others look at the circumstances before deciding. Either way, losing your license can bring significant changes to your daily life.
How a DUI Conviction Affects College and Employment
A DUI can show up on your record when you apply for college or jobs. Schools or potential employers might ask why you have a conviction, but they usually also care about how you handled the situation. You can use it as a chance to explain what you learned and how you plan to make better choices.
Here are some ways a DUI might affect your future:
- College applications: Some schools ask for details on past offenses. If they do, be honest and focus on what you’ve learned.
- Scholarships: Certain grants require a clean record, so a DUI could affect eligibility.
- Job searches: Employers may run a background check. Showing responsibility in your recovery can make a difference.
- Professional licenses: Careers that need special licensing (like nursing or teaching) may have extra steps if you have a DUI on record.
Many individuals who receive a DUI under 21 successfully continue their education and begin their careers. Taking proactive steps, such as attending required classes and following all court orders, can help you move forward.
Additional Consequences of Getting a DUI Under 21
You might have trouble getting to work, school, volunteering roles, or social events. If that happens, you can explore possible solutions. Some states offer a restricted or hardship license that allows you to drive to necessary places, such as your job or classes.
You may also be required to show proof of financial responsibility with a special insurance policy or meet other criteria before you can drive again. These programs can feel strict, but they’re designed to help you continue important parts of your life while you work through any minor DUI consequences.
DUI Consequences Under 21: Ignition Interlock Device Installation
Many states require an ignition interlock device (IID) for drivers with a DUI conviction. This device tests your breath for alcohol before you can start your car. If it detects alcohol, your engine won’t turn on. An IID is a proven tool for staying safe on the road.
With more than 5,200 installation locations across the country, Intoxalock is a leading provider of IIDs. If you need to meet your underage DUI IID requirements, talk to a state specialist at 888-283-5899 for step-by-step assistance.
Voluntary Car Breathalyzers for Underage Drivers
IIDs can also be installed voluntarily. Voluntary IIDs offer peace of mind by promoting safe driving habits and helping underage young people resist peer pressure. They also provide critical support for anyone who may be struggling with alcohol use.
In instances where an IID isn’t required in an underage DUI case, you can still voluntarily install one in your vehicle. When IIDs are not court-mandated, there is no government monitoring. Special pricing options are available for voluntary installations – follow the link for more information!
