You’re young. You’re just getting started. And suddenly, flashing lights change everything. Whether you’re the one facing charges or a concerned parent, it’s natural to feel overwhelmed and scared. You’re not alone if you’re asking, What happens if you get a DUI under 21 in Colorado?
At The Harrell Law Firm, PLLC, we regularly help young people and their families understand the legal consequences of underage drinking and driving. While the penalties can be serious, the right legal guidance can help you manage the outcome and begin the path forward with confidence.
Colorado BAC Limit Under 21
Colorado has a zero-tolerance policy for underage drinking and driving. While adults are considered legally impaired with a blood alcohol content (BAC) of 0.08% or higher, the Colorado BAC limit for those under 21 is just 0.02%. That means even a single drink could put a minor over the limit.
Law enforcement can charge someone under 21 with:
- Underage drinking and driving (UDD)—if the BAC was between 0.02% and 0.05%;
- Driving while ability impaired (DWAI)—for a BAC between 0.05% and 0.08%; or
- Driving under the influence (DUI)—for a BAC of 0.08% or more.
Each of these charges carries different penalties, and multiple offenses lead to escalating consequences.
Penalties for DUI Under 21 in Colorado
If you’re under 21 and charged with DUI, you can face both criminal and administrative penalties, depending on your BAC and whether it’s a first offense.
First UDD Conviction
If you’re charged with underage drinking and driving (UDD), you can expect the following penalties:
- Fines of up to $100,
- Up to 24 hours of public service,
- A three-month driver’s license suspension,
- Alcohol education and therapy courses, and
- Four points on your driving record.
These consequences are designed to discourage repeat offenses and encourage responsible decision-making moving forward.
First DUI Conviction
A first DUI conviction for those under 21 carries more severe consequences than a UDD. You may face:
- Up to one year in jail;
- Fines up to $1,000;
- Community service for 48–96 hours;
- License revocation for 9 months;
- Mandatory alcohol education classes; and
- Addition of 12 points to your driving record.
The penalties can escalate quickly with subsequent offenses, so it’s important to handle the first incident with care and legal support. Additional offenses result in even harsher consequences, which is why it’s so important to resolve the first one carefully.
In many cases, the court may also impose probation. If you violate the terms of your probation, you could face harsher penalties. Second and third offenses bring even more serious consequences, including longer license suspensions, higher fines, and possible jail time.
Administrative Penalties from the Colorado DMV
In addition to criminal court consequences, you’ll also face administrative penalties through the Colorado Department of Revenue. These are triggered automatically and handled separately from your criminal case.
If you test above the legal BAC limit or refuse a chemical test:
- Your license can be suspended for 3 to 9 months or more;
- You may be required to install an ignition interlock device to regain driving privileges; and
- You must pay reinstatement fees and provide SR-22 insurance.
Missing the deadline to request a DMV hearing can result in immediate loss of driving privileges. That’s one of the many reasons it’s crucial to take swift action.
How Long Does a Minor DUI Stay on Your Record?
A common question we hear is, How long does a minor DUI stay on your record? In Colorado, a DUI conviction stays on your record permanently, even if you were under 21 when it happened. Colorado does not allow expungement or sealing of DUI convictions, even for minors.
That means a conviction could affect:
- College admissions and financial aid eligibility,
- Employment opportunities,
- Housing applications, and
- Professional licensing.
The long-term effects can be serious, especially for young people just beginning to build their futures.
Additional Consequences for Minors
A DUI charge can also lead to disciplinary action at school or within sports or extracurricular programs. If you are in college and live on campus, you may face housing penalties or academic sanctions. For minors still in high school, there may be consequences at home or with driving to and from school activities.
It’s important to consider not just the legal penalties but also the personal and social effects a DUI can have at this stage of life.
