Maryland operates a near-zero tolerance framework for drivers under 21. A BAC of 0.02 or higher triggers administrative license action — well below the 0.08 per se DUI threshold that applies to drivers 21 and older. Under 21 with BAC 0.02 to less than 0.08 generally triggers a license suspension and administrative consequences. Under 21 with BAC 0.08 or higher means the same DUI charges under Md. Code, Transp. § 21-902 that apply to anyone else, plus additional underage consequences. Collateral effects — provisional license loss, college disciplinary action, federal student aid disruption, future employment and insurance impact — often outweigh the direct criminal penalties for young drivers.
An underage DUI in Maryland is rarely just a traffic case. The driver is often a high school senior, a college student, or someone early in their career — and the case touches systems beyond the criminal court that can shape their next 5 to 10 years. Understanding what the case actually affects is the first step in deciding how to handle it.
Maryland’s Near-Zero Tolerance Law
Maryland’s framework for drivers under 21 is sometimes called “zero tolerance,” though that label is not literally accurate. The actual administrative threshold is 0.02 BAC under the implied consent framework in Md. Code, Transp. § 16-205.1 — meaning a BAC reading of 0.02 or above triggers administrative license consequences for a driver under 21.
Practically, 0.02 BAC means almost any detectable alcohol triggers consequences. A single drink can produce a BAC reading in the 0.02 to 0.04 range depending on the driver’s weight, time elapsed, and the strength of the drink. For drivers under 21, the safest assumption is that any alcohol consumption before driving creates legal exposure.
The administrative penalty structure for under-21 drivers with BAC 0.02 to less than 0.08 is generally a license suspension — 6 months for a first offense, 1 year for a second. As with adult DUI cases, Ignition Interlock Program participation may be available as an alternative to the full suspension period.
The BAC 0.08 Line: When Underage Becomes a Regular DUI
If an under-21 driver’s BAC is 0.08 or higher, the case is charged under Md. Code, Transp. § 21-902 — the same DUI statute that applies to adult drivers. The driver’s age does not eliminate or reduce the underlying DUI charge. It adds underage-specific consequences on top.
For an under-21 driver with BAC 0.08 or higher:
- The DUI charge under § 21-902(a) carries up to 1 year in jail, a $1,000 fine, and 12 MVA points — same as adult first-offense DUI;
- The administrative suspension is generally longer than the standard adult schedule due to the underage status;
- Underage drinking charges may be added under the alcoholic beverages provisions (typically a citation, not a stand-alone criminal case);
- Provisional license holders face additional consequences specific to the limited license they hold; and
- The collateral effects discussed below all apply.
For the underlying penalty framework that applies regardless of age, see first-offense DUI penalties in Maryland.
Provisional License Holders: Additional Consequences
Most Maryland drivers under 18, and many drivers between 18 and 21, hold a provisional license under Md. Code, Transp. § 16-111 — a license with built-in restrictions on hours, passengers, and driving privileges. An alcohol-related offense by a provisional license holder triggers additional consequences beyond the standard underage framework.
Provisional license-specific consequences typically include extended provisional periods, additional MVA action, mandatory completion of a Driver Improvement Program, and (in some cases) revocation of the provisional license entirely. The driver may face a delayed transition to a full license that would otherwise have occurred automatically.

College and Academic Consequences
College students charged with underage DUI in Maryland face consequences that go well beyond the criminal court. Most Maryland colleges and universities — and most colleges nationally — have student conduct codes that treat any criminal arrest or charge as a reportable event. A DUI charge may trigger:
- Student conduct review and disciplinary proceedings, independent of the criminal case outcome;
- Loss of on-campus housing, scholarship status, or athletic eligibility;
- Suspension or expulsion in cases involving accidents or repeat violations; and
- Reporting obligations on applications to graduate or professional schools, regardless of how the criminal case ultimately resolves.
The student conduct process operates independently of the criminal court. A successful PBJ in the criminal case does not automatically resolve the student conduct case, and a college disciplinary record can follow a student in ways the criminal record does not.
Federal Student Aid Eligibility
Federal student aid eligibility historically included a drug-conviction question that affected aid eligibility for students with drug-related criminal convictions. That specific provision has been largely scaled back, but Maryland students should still understand that drug-related charges (separate from alcohol DUI) can still affect aid eligibility in certain circumstances. Alcohol DUI alone is generally not a federal aid disqualification, but combined drug-and-alcohol cases or drug-related charges arising from the same stop can trigger separate consequences.
Each year’s FAFSA paperwork should be reviewed carefully by any student with a pending alcohol or drug case. The reporting requirements have shifted in recent years and continue to evolve.
Insurance Impact on Young Drivers
Insurance premiums for drivers under 25 are already substantially higher than the average — and an underage DUI conviction can multiply that base rate. Some carriers will not insure an under-21 driver with a recent DUI conviction at all, forcing the driver onto a parent’s policy (with the parent’s permission and potential cost increase) or into the nonstandard insurance market.
Even a Probation Before Judgment outcome can affect insurance premiums for young drivers, though the impact is typically substantially less than a conviction. The MVA-side administrative suspension also factors into insurance calculations — the SR-22 financial responsibility filing that often follows a DUI compounds the premium effect.
Future Employment and Background Checks
A DUI charge or conviction at age 19 affects employment background checks for years. For careers that involve driving, security clearances, professional licensure, federal employment, or work with vulnerable populations, the question is not whether the DUI will appear in a background check — it is whether the candidate has a plausible explanation and whether the resolution was the best available.
A successful PBJ generally allows the candidate to truthfully answer “no” to most “have you been convicted of a crime” questions on standard employment applications. A criminal conviction (DUI or DWI) does not allow that answer. The difference matters more for young people who will face these questions repeatedly in early-career job applications, graduate school applications, and security clearance processes.
The PBJ Angle for First-Time Underage Offenders
Probation Before Judgment under Maryland Code, Criminal Procedure § 6-220 is often the most important outcome to push toward in an underage DUI case. A successful PBJ:
- Avoids the criminal conviction on the record (subject to disclosure exceptions);
- Preserves the ability to answer “not convicted” on most background check questions;
- Reduces (though does not eliminate) the insurance impact; and
- Allows the driver to apply for expungement of the case record after the probationary period in many circumstances.
PBJ availability for an underage DUI depends on the same factors as adult cases — the judge, the facts, the driver’s record, and how prepared the defense is at sentencing. The 10-year PBJ bar for prior alcohol-related dispositions also applies to underage cases. A driver who used a PBJ on a 17-year-old’s underage drinking case cannot also use PBJ on a 19-year-old’s DUI within 10 years of the first.
Out-of-State College Students in Maryland
Many Maryland colleges and universities draw students from out of state. A non-resident student under 21 charged with DUI in Maryland faces both Maryland’s underage framework and the Driver License Compact reporting that sends the conviction back to the student’s home state.
The home state then applies its own underage rules, which can include separate license action, additional alcohol education requirements, and home-state administrative suspensions independent of the Maryland action. The student may face two parallel administrative processes on top of the criminal case.

An Underage DUI Affects a Young Driver’s Future for Years
For an under-21 driver, the criminal penalty is rarely the full picture. College conduct cases, student aid implications, provisional license issues, insurance multipliers, and background-check consequences all stack on top of the underlying DUI or underage drinking and driving charge. A Probation Before Judgment can make the difference between a clean future record and a conviction that follows the driver for a decade. The MVA per se hearing deadline runs quickly after the stop — start the case early.
