Charged with DUI in St. Mary’s County, Maryland? If you are facing a DUI or DWI charge in St. Mary’s County, you are dealing with one of the most serious criminal offenses on the books — one that can cost you your driver’s license, your freedom, and your career. The consequences begin immediately: you have just 10 days from the date of your arrest to request a hearing with the Maryland Motor Vehicle Administration (MVA) to protect your driving privileges. Miss that deadline, and your license suspension takes effect automatically. At SoMD Criminal Defense, attorneys Jeremy Widder and Kathryn Batey provide aggressive, strategic DUI defense for clients charged throughout St. Mary’s County, including in Leonardtown, Lexington Park, California, Great Mills, Mechanicsville, Hollywood, Charlotte Hall, and Ridge.
St. Mary’s County presents unique challenges for DUI defendants. As home to Patuxent River Naval Air Station, a large portion of the local population holds military positions, government jobs, or security clearances that can be directly threatened by a DUI charge. Maryland DUI law is technically complex, and the local courts take impaired driving cases seriously. Whether your arrest involved a traffic stop on Route 235, a sobriety checkpoint on Route 5, or an incident near base, you need a DUI attorney in St. Mary’s County MD who understands both the law and the local landscape.
DUI Penalties in St. Mary’s County
Maryland law draws a distinction between DUI (driving under the influence, BAC of .08 or higher) and DWI (driving while impaired, BAC of .07 or evidence of impairment). Both are criminal offenses, and St. Mary’s County prosecutors pursue them aggressively.
A first DUI offense carries up to one year in jail, a $1,000 fine, 12 points on your driving record, and a potential license suspension. A first DWI offense carries up to 60 days in jail, a $500 fine, and 8 points on your license. Repeat offenses carry significantly harsher penalties — a second DUI conviction can result in up to two years of incarceration, a $2,000 fine, and mandatory minimum jail time. For drivers under 21, Maryland enforces a lower BAC threshold of .02.
Beyond the criminal penalties, a DUI conviction in St. Mary’s County can have devastating collateral consequences. Your insurance premiums will increase substantially. Your employment may be jeopardized — particularly if you work at NAS Patuxent River, hold a security clearance, or serve in the military. You may be required to install an ignition interlock device on your vehicle. A DUI conviction creates a criminal record that follows you for years and can affect housing, professional licensing, and future opportunities. The stakes are too high to face these charges without a knowledgeable DUI lawyer in St. Mary’s County on your side.
How We Defend DUI Cases in St. Mary’s County
Every DUI arrest follows a specific sequence of events, and each step presents potential defenses. Our DUI defense attorneys examine every detail of your case, including:
- The traffic stop — Did the officer have reasonable articulable suspicion to initiate the stop? An unconstitutional stop can result in the suppression of all evidence gathered afterward.
- Field sobriety tests — Were the Standardized Field Sobriety Tests administered in strict accordance with NHTSA protocols? Were environmental factors such as lighting, road surface conditions, and weather properly documented? Officers in St. Mary’s County frequently administer these tests on uneven road shoulders along Route 235 and Route 5, and the results may be unreliable.
- Breathalyzer results — Was the Intoximeter EC/IR II properly calibrated and maintained according to the required schedule? Was the mandatory 20-minute observation period observed before the test? Was the operator currently certified? Breath test results are not infallible, and a DUI lawyer in St. Mary’s County who understands the science behind these machines knows how to challenge them effectively.
- Blood test procedures — If a blood draw was performed, was it conducted by qualified medical personnel? Was the chain of custody maintained from the time the sample was drawn through testing?
- Probable cause for arrest — Did the officer have probable cause to place you under arrest for DUI? If the totality of the circumstances did not support an arrest, the charges may be vulnerable to a suppression motion.
- Officer observations and video evidence — Are the officer’s written observations of impairment consistent with what the body camera and dashcam footage actually show? Inconsistencies between the police report and video evidence can be powerful tools for the defense.
We regularly appear in St. Mary’s County District Court in Leonardtown and St. Mary’s County Circuit Court, and we are familiar with the prosecutors, judges, and procedures specific to this jurisdiction. We file suppression motions when constitutional violations have occurred, challenge the reliability and admissibility of chemical testing, and negotiate with the St. Mary’s County State’s Attorney’s Office for reduced charges when the facts support it. Many DUI cases can be reduced to lesser offenses or dismissed entirely when the evidence is carefully challenged by an experienced DUI defense attorney.
A DUI arrest also triggers a separate administrative proceeding with the Maryland MVA. You must request your MVA hearing within 10 days to contest the automatic suspension of your license. Our firm handles both the criminal defense in court and the MVA administrative hearing to give you the strongest possible protection of your driving privileges.
DUI Enforcement in St. Mary’s County
St. Mary’s County law enforcement maintains an active presence on the county’s two primary corridors, and understanding where and how DUI enforcement happens can be important context for your defense. Route 235 — Three Notch Road — is the main commercial and commuter artery running from Hughesville through Mechanicsville, Charlotte Hall, Hollywood, Lexington Park, and into the Patuxent River NAS area. It is the most heavily patrolled road in St. Mary’s County for impaired driving, particularly on weekend nights and during shift changes at the base. Route 5 — Point Lookout Road — runs from Leonardtown through Great Mills, California, and south toward Point Lookout State Park, and is another primary enforcement corridor.
The St. Mary’s County Sheriff’s Office and Maryland State Police regularly conduct sobriety checkpoints along these routes, particularly during holiday weekends including Memorial Day, the Fourth of July, Labor Day, and the winter holiday season. The area around Lexington Park — with its concentration of restaurants, bars, and proximity to the base — sees especially high enforcement activity. If you were arrested at a sobriety checkpoint in St. Mary’s County, additional constitutional defenses may apply, as checkpoint procedures must comply with specific legal requirements to be valid.
Military DUI Defense in St. Mary’s County
St. Mary’s County is home to Patuxent River Naval Air Station, one of the largest employers in Southern Maryland and a hub for military aviation testing and evaluation. Thousands of active-duty service members, reservists, and military families live and work in the surrounding communities of Lexington Park, California, and Great Mills. For military personnel, a DUI arrest creates a dual-track legal crisis that most DUI lawyers are not equipped to handle.
When a service member is arrested for DUI in St. Mary’s County, they face the full weight of Maryland’s criminal justice system — the same charges, penalties, and court proceedings as any civilian. But they also face a separate and parallel set of consequences under the Uniform Code of Military Justice (UCMJ). A DUI can trigger non-judicial punishment under Article 15, formal court-martial proceedings, administrative separation, loss of rank, forfeiture of pay, and the loss of a security clearance that may be essential to their duties. Even if the civilian case results in a favorable outcome, the military chain of command can impose its own discipline independently.
The outcome of the civilian case matters enormously for the military side. A conviction makes military consequences nearly certain. A dismissal, acquittal, or favorable plea arrangement gives the service member significantly more leverage when dealing with their command. At SoMD Criminal Defense, we understand the interplay between civilian DUI prosecution and military administrative and disciplinary proceedings, and we fight to achieve outcomes in the St. Mary’s County courts that protect our clients’ military careers.
DUI and Your Military Career at Pax River
The impact of a DUI charge in St. Mary’s County extends well beyond active-duty military personnel. NAS Patuxent River employs thousands of government contractors, civilian Department of Defense employees, and support staff whose livelihoods depend on maintaining base access and security clearances. A DUI arrest can set off a chain of professional consequences that threatens your ability to do your job and support your family.
Government contractors working at Pax River are typically required to self-report any criminal arrest to their employer and to their security clearance adjudicator. A DUI charge can trigger a review or suspension of your clearance while the case is pending, effectively removing you from your position until the matter is resolved. For civilian employees of the federal government, including those employed directly by NAVAIR, a DUI conviction can result in disciplinary action, loss of driving privileges on base, and negative impacts on performance evaluations and career advancement.
Even if you do not hold a security clearance, a DUI conviction can affect your professional standing, your ability to maintain professional licenses, and your reputation within the tight-knit defense community that surrounds Patuxent River. A DWI attorney in Lexington Park who understands these professional stakes will fight not just to protect your criminal record, but to protect your career. At SoMD Criminal Defense, we recognize that for many of our St. Mary’s County clients, the professional consequences of a DUI are the most urgent concern, and we tailor our defense strategy accordingly.
Probation Before Judgment and DUI Expungement
For some DUI defendants in St. Mary’s County, Probation Before Judgment (PBJ) may be available. A PBJ means the court places you on probation without entering a formal conviction on your record. While a PBJ still results in points on your driving record and will appear on certain background checks, it avoids the most damaging consequences of a full DUI conviction — including the criminal record that comes with it. For military personnel and government employees at Pax River, a PBJ can be the difference between keeping your career and losing it.
Importantly, Maryland law changed in October 2024 to allow expungement of DUI and DWI charges that resulted in a PBJ after a waiting period of 15 years. This is a significant development for anyone who received a PBJ for a DUI offense years ago and has been waiting for the opportunity to clear their record. If you believe you may be eligible for DUI expungement in St. Mary’s County, our attorneys can evaluate your case and guide you through the process.

Frequently Asked Questions About DUI in St. Mary’s County
How much does a DUI lawyer cost in St. Mary’s County?

How will a DUI affect my military career?
A DUI arrest can have severe consequences for military personnel stationed at or near NAS Patuxent River. In addition to the civilian criminal penalties, you may face non-judicial punishment under Article 15 of the UCMJ, administrative separation proceedings, loss of rank, forfeiture of pay, and suspension or revocation of your security clearance. How your civilian case is resolved directly impacts the severity of the military consequences. Securing a dismissal, acquittal, or favorable plea in St. Mary’s County court gives you the strongest position when facing your chain of command.
What happens at a DUI checkpoint in St. Mary’s County?
DUI checkpoints in St. Mary’s County are typically set up on Route 235 (Three Notch Road) or Route 5 (Point Lookout Road), particularly during holiday weekends and high-enforcement periods. At a checkpoint, officers briefly stop each vehicle and look for signs of impairment. If the officer suspects you have been drinking, you may be directed to a secondary screening area for field sobriety tests and a preliminary breath test. Checkpoints must comply with specific constitutional requirements — including advance public notice and a neutral, non-arbitrary stopping pattern — and a failure to follow these procedures can provide grounds for challenging the legality of your arrest.

Will a DUI affect my government job?
Yes, a DUI can significantly affect your government employment, particularly if you work at NAS Patuxent River or hold a security clearance. Most government contractors and federal civilian employees are required to self-report criminal arrests to their employer and clearance adjudicator. A DUI charge can trigger a clearance review or suspension, which may effectively remove you from your position until the case is resolved. A conviction can lead to revocation of your clearance and loss of employment. The outcome of your criminal case is the single most important factor in minimizing the impact on your government career, which is why hiring an experienced DUI defense attorney in St. Mary’s County Maryland is critical.
