Maryland’s underage drinking and driving law is one of the strictest in the country. For any driver under 21, a blood alcohol concentration of 0.02 or higher is enough to trigger a DUI charge. Here is what Calvert County families should understand before, and especially after, a stop involving a teen or college aged driver.
If you are the parent of a teenager in Calvert County, this is the article I would want you to read. Maryland treats underage drinking and driving with a zero-tolerance framework that can blindside families who did not know how strict the law actually is. The phone call from Prince Frederick District Court about your 18-year-old son or 20-year-old college student comes as a shock. It does not have to.
As a defense attorney who has represented underage drivers across Calvert County, I have seen these cases play out in Prince Frederick, Solomons, Huntingtown, the twin beaches, and every other community in the region. The stakes are real. Defense strategies differ from those in adult cases. And the window to protect your child’s future is short.
What Maryland’s Zero Tolerance Law Actually Says
Maryland Transportation Article § 21-902 governs DUI and DWI charges. For drivers under 21, the law includes a specific provision: any BAC of 0.02 or higher creates a presumption that the driver was impaired. That is one quarter of the 0.08 threshold that applies to adults.
At 0.02 BAC, a typical 150 pound teenager has consumed approximately one standard drink within the past hour. One beer. One glass of wine. A half shot of liquor. Any of these can put an underage driver over the legal limit.
The Charges That Can Apply
- DUI per se under § 21-902(a) for any adult driver over 0.08
- DWI under § 21-902(b) for any driver showing impairment
- Underage DUI under § 21-902(c) for drivers under 21 with BAC at 0.02 or higher
- Underage drinking charges under state alcohol laws
- False identification charges if a fake ID was involved
- Other passenger-related charges if other minors were in the vehicle
The Penalties Go Beyond the Typical DUI
An underage DUI conviction brings several consequences that adult cases do not:
Automatic License Suspension
For a first underage DUI, Maryland imposes a mandatory 180 day license suspension. There is no “hardship license” category for underage drivers the way there sometimes is for adults. The 180 days run without exception.
Criminal Record Implications
Even when the underage driver is a legal adult (18 to 20), the DUI conviction goes on the criminal record. College applications, financial aid, future employment, and professional licensing can all be affected.
College Consequences
Many universities have their own disciplinary policies covering criminal arrests. A DUI charge, even one that does not result in conviction, can trigger a student conduct review, academic probation, loss of scholarships, or housing consequences.
Insurance Impact
Adding an underage DUI to a family insurance policy can double or triple rates. Some insurers will not cover the young driver at all after a DUI.
Parental and Financial Exposure
Parents often face the financial fallout directly. Legal fees, interlock costs, treatment program fees, and insurance spikes all add up quickly.
For parents: Do not assume a first time underage DUI will resolve with a slap on the wrist. Maryland’s zero tolerance framework produces consequences that follow young people into adulthood. A defense attorney’s job is to minimize those consequences before they become permanent.
How These Cases Typically Happen in Calvert County
The most common scenarios in our underage DUI files:
House Party Returns
A teenager attends a party at a friend’s house where alcohol is available. The drive home, often late at night on back roads, produces a stop for equipment or speed. The officer smells alcohol and develops probable cause.
Waterfront Gatherings
Private beach parties, boat gatherings, and waterfront events draw young people. The drive home along Route 2/4 or MD 261 produces the stop.
College Student Visits
College students home for summer or holiday breaks who attend local events or visit friends often end up stopped on Route 4 or Route 2/4. They are not in their college town, and the stop is often the first DUI interaction of their lives.
Fake ID Use
Students who used a fake ID to gain entry to a restaurant or bar may face additional charges if the ID is discovered during the stop.
The Specific Defense Approach for Underage Cases
Defending an underage DUI is not the same as defending an adult DUI. The stakes are different, the long term consequences are different, and the strategic options are different. Key considerations include:
Probation Before Judgment
PBJ can be especially valuable for underage defendants because it keeps the conviction off the record. Calvert County judges consider PBJ for first offense underage DUI cases where the defendant has a clean record and takes initiative to address the underlying issues.
Treatment and Education Programs
Voluntary enrollment in alcohol education and assessment before court demonstrates accountability. Judges notice this, and it affects outcomes. Maryland’s juvenile and young adult diversion programs also exist but have eligibility rules.
Challenging the Stop
The same constitutional protections apply to underage drivers. If the stop lacked reasonable articulable suspicion, the evidence that followed can be suppressed. Young drivers sometimes consent to things (vehicle searches, field sobriety tests) that they did not realize they could decline. A defense attorney can push back on that at the suppression stage.
Challenging the Breath Test
The 20 minute observation requirement, the calibration logs, and the operator certification all apply to underage cases the same way they apply to adult cases. Defects in any of these can undermine the state’s case.

What Parents Should Do First
If your underage son or daughter has been arrested for DUI in Calvert County:
- Do not discuss the case with anyone except an attorney. Social media, text messages, and phone calls can all become evidence.
- Note the 10 day MVA deadline. The suspension clock runs the same way for underage drivers as for adults.
- Contact a defense attorney before the first court date in Prince Frederick.
- Gather documentation that supports your child’s character: school records, transcripts, employment records, volunteer work.
- Consider voluntary enrollment in an alcohol education program before court. This matters to judges.
For college bound students: Many colleges require disclosure of criminal charges on applications or during enrollment. Act quickly to resolve the case in a way that minimizes the long term disclosure burden.
