A first offense DUI in Maryland is a serious criminal charge that can result in jail time, heavy fines, a suspended license, and a permanent criminal record. If you have been arrested for driving under the influence in Charles County, Calvert County, St. Mary’s County, or Prince George’s County, understanding the penalties, the court process, and your defense options is critical. The decisions you make in the days following your arrest can significantly affect the outcome of your case.
At SoMD Criminal Defense, our attorneys handle DUI and DWI cases throughout Southern Maryland. We know the prosecutors, the judges, and the specific procedures at the Charles County District Court. This guide explains everything you need to know about a first DUI offense in Maryland.
DUI vs. DWI: What’s the Difference?
Maryland distinguishes between two alcohol-related driving offenses. DUI (Driving Under the Influence) under Maryland Transportation § 21-902(a) applies when a driver is substantially impaired by alcohol. This is typically charged when a driver’s blood alcohol concentration (BAC) is 0.08 or higher, or when the driver exhibits clear signs of impairment. DWI (Driving While Impaired) under § 21-902(b) is a lesser offense that applies when a driver is impaired to some extent by alcohol. A DWI is typically charged when BAC is between 0.07 and 0.08, or when the evidence of impairment is less conclusive. Both charges are serious, but DUI carries more severe penalties.
Penalties for a First DUI Offense in Maryland
A first DUI conviction under Maryland Transportation § 21-902(a) carries up to 1 year in jail and a fine of up to $1,000. A first DWI conviction carries up to 60 days in jail and a fine of up to $500. In addition to criminal penalties, you face 12 points on your driving record for a DUI (8 for a DWI), which results in an automatic license revocation. You may also be required to install an ignition interlock device on your vehicle, complete an alcohol education program, and submit to a substance abuse evaluation.
In practice, first-time DUI offenders in Charles County rarely receive the maximum jail sentence. However, the collateral consequences — including a criminal record, increased insurance rates, employment difficulties, and the stigma of a DUI conviction — can follow you for years.
The MVA Hearing: Protecting Your License
In addition to the criminal case, a DUI arrest triggers a separate administrative hearing at the Maryland Motor Vehicle Administration (MVA). If you took a breath test and your BAC was 0.08 or higher, or if you refused the test entirely, the MVA will move to suspend your license. You have only 10 days from the date of your arrest to request a hearing. If you miss this deadline, your license will be automatically suspended.
The MVA hearing is separate from your court case and is conducted by an administrative law judge. Your attorney can represent you at this hearing and argue that the suspension should be modified. Even if the suspension is upheld, your attorney may be able to secure a restricted license that allows you to drive to work, school, or medical appointments with an ignition interlock device.
If you were recently arrested for DUI in Southern Maryland, time is critical. You have only 10 days to request your MVA hearing. Call SoMD Criminal Defense at (301) 818-0389 or contact us online for a free consultation.
Probation Before Judgment (PBJ) for First-Time DUI Offenders
One of the most important tools available to first-time DUI offenders in Maryland is Probation Before Judgment (PBJ). A PBJ means the judge enters a finding of guilt but does not enter a conviction on your record. Instead, you are placed on probation with conditions that may include community service, alcohol education, substance abuse treatment, and no further violations of law. If you successfully complete probation, you avoid a criminal conviction entirely.
A PBJ is particularly valuable in DUI cases because it also reduces the points assessed against your license from 12 to 8, which can mean the difference between a revocation and a suspension. For a detailed explanation, see our guide on Probation Before Judgment in Maryland DUI cases. Not all defendants are eligible for PBJ, and the decision is entirely within the judge’s discretion. Having an experienced DUI attorney advocate for PBJ on your behalf significantly improves your chances.
The ignition interlock requirement is another critical consideration for first-time DUI offenders. Maryland may require you to install an ignition interlock device (IID) on your vehicle as a condition of license reinstatement. The IID requires you to provide a breath sample before the vehicle will start and periodically while driving. The cost of the device, installation, and monthly monitoring fees can add up quickly, making it even more important to fight for the best possible outcome in your case.
Common Defenses to DUI Charges
An experienced DUI defense attorney can challenge the State’s case in several ways. Common defenses include challenging the initial traffic stop (if the officer lacked reasonable suspicion, all evidence from the stop may be suppressed), challenging the field sobriety tests (these tests are subjective and can be affected by medical conditions, road conditions, footwear, and weather), challenging the breathalyzer results (breath testing equipment must be properly calibrated and maintained, and the test must be administered correctly), and challenging the officer’s observations (the officer’s testimony about signs of impairment may be contradicted by dashcam or body camera footage).

What to Expect at Your DUI Court Dates in Charles County
After a DUI arrest in Charles County, your case will proceed through several stages at the District Court in La Plata. Your first appearance will be a preliminary hearing where you are formally advised of the charges and your rights. If you have not already done so, this is the time to retain an attorney. Your attorney can enter your appearance and begin requesting discovery, which includes the police report, any video footage, breath test maintenance records, and the officer’s training certifications.
Before trial, your attorney may file pre-trial motions challenging the legality of the traffic stop, the administration of field sobriety tests, or the reliability of the breathalyzer results. If any of these motions are successful, key evidence may be suppressed, significantly weakening the State’s case. Your attorney will also negotiate with the prosecutor to explore whether a favorable plea agreement is possible, including PBJ, reduced charges, or a stet.
If the case proceeds to trial, it will be heard by a judge in a bench trial. The State must prove beyond a reasonable doubt that you were driving or attempting to drive while under the influence of or impaired by alcohol. Your attorney can cross-examine the arresting officer, challenge the State’s evidence, and present testimony and evidence on your behalf. Many DUI cases are won on technical challenges to the evidence rather than outright denials of drinking.
DUI charges in Calvert County, St. Mary’s County, and Prince George’s County follow a similar process, though each jurisdiction has its own prosecutors, judges, and local practices. Having an attorney who regularly practices in these courts gives you a meaningful advantage because they understand the specific expectations and tendencies of the judges and prosecutors in each jurisdiction.
Frequently Asked Questions About First Offense DUI in Maryland
Will I go to jail for a first DUI in Maryland?
While jail time is a possibility, most first-time DUI offenders in Charles County and Southern Maryland do not receive jail sentences if they are represented by an attorney and eligible for PBJ or other favorable dispositions. The outcome depends on the specific facts of your case, your BAC, and whether there were any aggravating factors such as an accident or a minor in the vehicle.
How long will a DUI stay on my record in Maryland?
A DUI conviction remains on your criminal record permanently unless it is expunged. If you receive a PBJ, the charge may be eligible for expungement after 3 years. Under recent Maryland law changes, even some DUI convictions may now be eligible for expungement in certain circumstances.
What happens at the Charles County District Court for a DUI case?
Your case will be heard at the Charles County District Court in La Plata. You will typically have a preliminary appearance, followed by a trial date. Most DUI cases in District Court are bench trials (before a judge, not a jury). Your attorney will review the evidence, file any necessary motions, and either negotiate a resolution or take the case to trial.
Should I refuse the breathalyzer test in Maryland?
Refusing the breathalyzer test has both advantages and disadvantages. A refusal means the State will not have a BAC number to use against you in court. However, refusing triggers an automatic 270-day license suspension (compared to 180 days for a failed test), and the fact that you refused can be used as evidence of consciousness of guilt. Consult with an attorney immediately to discuss the best strategy for your situation.
