Maryland DUI penalties range from up to 1 year in jail and a $1,000 fine for a first offense, up to 2 years and $2,000 for a second offense, and up to 3 years and $3,000 for a third offense, plus license suspension, 12 points on your driving record, and mandatory ignition interlock. DWI penalties are lower, starting at 2 months and $500 for a first offense. Aggravating factors like a high BAC, a minor in the vehicle, or a prior conviction can push these numbers significantly higher.
At the Law Offices of Alex Poberesky, P.A., we’ve helped Maryland drivers through DUI arrests for more than 25 years. This guide breaks down Maryland DUI penalties for first, second, and third offenses in plain language. Whether you were charged with DUI, charged with DWI, or any other impaired driving offense in the state of Maryland, you may face serious penalties that follow you for years.
Understanding DUI and DWI in Maryland: What’s the Difference
Maryland is one of only a handful of states that treat DUI and DWI as two separate charges. Most people use the terms interchangeably, but the law sees them very differently.
A DUI (Driving Under the Influence) applies when your blood alcohol concentration is 0.08 or higher while operating a motor vehicle. Under the Maryland Transportation Article, § 21-902(a), this is sometimes called “per se” DUI because the BAC number alone can prove the case.
A DWI (Driving While Impaired) is the less serious of the two charges. It usually applies when your BAC is around 0.07 or when an officer believes you’re impaired by alcohol to some visible degree, even if your BAC falls below 0.08.
Here’s the quick version.
| Charge | BAC Level | Severity |
| DUI | 0.08 or higher | More serious |
| DWI | Around 0.07 or visible impairment | Less serious |
| Underage drivers | 0.02 or higher (under 21) | Zero tolerance |
| Commercial license | 0.04 or higher | CDL at risk |
Driving while impaired by drugs (including prescription medication) falls under the same statute. So does driving under the influence of marijuana or other controlled substances. Maryland law prohibits driving or attempting to drive in any of these conditions. That’s why we see so many drinking and driving offenses get charged right alongside drug-related impairment counts.
Maryland’s Two-Track Process After a DUI Arrest
One of the biggest surprises for people after a DUI arrest is learning that the case moves through two separate systems at the same time.
Track 1: Criminal Court. Your criminal case moves through the Maryland District Court, where a judge decides guilt and sets any jail time, fines, or other criminal penalties.
Track 2: Motor Vehicle Administration. Your driver’s license is handled separately by the Maryland Motor Vehicle Administration (MVA). This is a civil proceeding about your driving privileges.
Here’s how the timeline works.
- Day 1: You’re arrested. Your driver’s license is confiscated, and you’re given a 45-day temporary paper license.
- Day 10: You have only 10 days from the traffic stop to request an MVA hearing. Miss it, and you lose your chance to fight the license suspension.
- Day 46: If no hearing was requested, your suspension starts automatically.
This is why acting fast matters. A DUI attorney can file for the MVA hearing while also building your criminal defense. Waiting a few weeks to “figure things out” can cost you your license before the criminal case even starts.
Maryland DUI Penalties at a Glance
Before we break each offense level down, here’s the big-picture view of penalties for DUI in Maryland. These numbers come straight from Maryland Code, Transportation § 21-902 and § 27-101.
| Offense Level | Max Jail Time | Max Fine | License Action | Ignition Interlock |
| First DUI | 1 year | $1,000 | 6-month suspension | 6 months |
| Second DUI (within 5 years) | 2 years | $2,000 | 9- to 12-month suspension | 1 year |
| Third DUI | 3 years (up to 5 with aggravators) | $3,000 ($5,000 aggravated) | 18-month revocation | 3 years |
| First DWI | 2 months | $500 | Up to 6 months | If ordered |
| Second DWI | 1 year | $500 | Longer suspension | Usually required |
| Third DWI | Up to 3 years | Up to $3,000 | Extended suspension | 3 years |
Max penalties are the ceiling, not the default. Most first-time offenders with clean records never see the top of the chart. But judges have wide discretion, and factors like your BAC, whether anyone was hurt, and your behavior during the stop all affect what actually happens in your DUI case.
First-Time DUI in Maryland: What You’re Really Facing
A first-time DUI in Maryland can carry up to one year in jail and a fine of up to $1,000. If a minor was in the vehicle at the time, those ceilings jump to two years and $2,000. You’ll also pick up 12 points on your driver’s license, which makes your license eligible for revocation under Maryland’s points system.
But max penalties rarely hit first-time DUI offenders. For most drivers facing a first-time offense, here’s what tends to matter more.
-
Will You Go to Jail for a First-Time DUI in Maryland?
For a first-time DUI in Maryland with no prior record and no accident or injuries, actual jail time is uncommon. But it’s not impossible. Judges weigh several things: your BAC level, cooperation during the stop, whether anyone was hurt, and aggravating factors present during your DUI arrest. A driver with a 0.19 BAC and a child in the car is looking at a very different outcome than someone who blew 0.09 on a quiet road home.
-
Probation Before Judgment (PBJ) and Your First Offense
Probation Before Judgment (PBJ) is often the best possible outcome for a first-time DUI in Maryland. Under Maryland Code, Criminal Procedure § 6-220, a judge can strike the guilty finding and place you on probation. Complete the probation successfully, and the DUI conviction never goes on your criminal record.
A heads-up about the law. As of October 1, 2024, Maryland closed what was known as the “Noah’s Law loophole.” Before that date, a PBJ for DUI could help you skip the ignition interlock requirement. Not anymore. Even with a PBJ, you’ll now need to use an ignition interlock device.
-
License Suspension and MVA Consequences for a First DUI
Your driver’s license suspension lasts six months on a first DUI when your BAC is between 0.08 and 0.14. If your BAC was 0.15 or higher, or if you refused the breath test, the suspension period runs longer. Many drivers qualify for the ignition interlock program instead of full suspension, which can keep you behind the wheel during your suspension period.
Second DUI Offense in Maryland: The Stakes Get Higher
A second DUI within five years of a first conviction carries much heavier consequences. The maximum jail time doubles to two years, and the fine climbs to $2,000. Under Maryland Code § 27-101, there’s also a mandatory minimum of five days in jail if your prior conviction happened within the past five years.
Here’s something many drivers don’t realize. PBJ is not available for a second DUI. That second-chance option disappears the moment you’ve used it once for a drinking and driving offense, or the moment a judge decides you’ve already had your shot.
License consequences hit harder, too. Expect a 9- to 12-month suspension and a mandatory one-year ignition interlock. The MVA classifies repeat offenders as anyone with more than one DUI in five years, and second and subsequent offenses trigger longer interlock requirements across the board.
A second DUI also means mandatory alcohol and drug assessment. If the assessment recommends treatment, you’ll need to complete it as part of your sentence or probation. A skilled Maryland DUI lawyer can often push for treatment-based sentencing in place of straight jail time, depending on the facts.
Third DUI Offense in Maryland: Serious Penalties You Can’t Ignore
A third DUI offense is a different kind of case. Under § 27-101, the maximum penalty jumps to three years in prison and a $3,000 fine. In aggravated situations like transporting a minor, or where certain enhancements apply, a person convicted of DUI can face up to five years in jail and a $5,000 fine.
Mandatory jail time kicks in. If you have two prior DUI convictions within the past five years, you’re looking at a 10-day minimum sentence that can’t be suspended.
License consequences are severe. Your driver’s license faces an 18-month revocation. You’ll need an ignition interlock device for three full years once you regain driving privileges. You’ll also usually need SR-22 insurance proof to reinstate your license.
One thing most people don’t know. Time spent in an inpatient alcohol or drug treatment program can sometimes count toward mandatory jail time for a third DUI offense. This is a real option that a skilled Maryland DUI lawyer can push for where the facts support it. When you’re convicted of a DUI for the third time, creative sentencing can make a real difference in your life.
Aggravating Factors That Make Penalties for DUI Worse
Not every DUI offense looks the same. Certain factors trigger increased penalties, sometimes dramatically. Here are the circumstances that lead to additional penalties beyond the standard sentencing ranges.
| DUI Factor | Additional Penalties / Consequences |
|---|---|
| Minor passenger in the vehicle | Adds up to an extra year of jail and another $1,000 in fines. For DUI cases, maximum penalties rise to 2 years in jail and $2,000 in fines for a first offense, and 5 years in jail and $5,000 in fines for aggravated third-offense cases. |
| BAC of 0.15 or higher | Triggers longer license suspension, including 180 days for a first offense, and mandatory ignition interlock. |
| Chemical test refusal | Causes an automatic 270-day license suspension for a first refusal and a two-year suspension for a second refusal. The State can also add two months of jail and a $500 fine if the refusal was properly filed with notice. |
| Accident causing injury or death | May lead to vehicular manslaughter or life-threatening injury charges. These are no longer misdemeanors. |
| Commercial license holders | Results in a one-year CDL disqualification for a first DUI offense and lifetime CDL disqualification for a second offense. Hazmat drivers face a three-year disqualification on a first offense. |
| Under 21 drivers | Subject to a zero-tolerance 0.02 BAC limit and up to three years in the ignition interlock program. |
Roughly 75% of Maryland DUI arrests involve male drivers, and the 21 to 34 age group shows up most often in both arrests and fatal crashes. These patterns shape how prosecutors and judges approach cases in real courtrooms.
The Hidden Costs of a DUI Conviction
Jail time and fines are only the start. A DUI conviction reaches into parts of your life you may not have thought about yet.
- Employment and background checks.
A DUI shows up on Maryland criminal background checks unless expunged. Fields like healthcare, education, commercial driving, federal contracting, and finance all take these charges very seriously.
- Security clearances and federal jobs.
If you hold a security clearance, you’ll need to self-report the arrest. Not reporting is often treated worse than the DUI itself.
- Professional licenses.
The Maryland Board of Nursing, the Board of Physicians, and the Maryland State Bar all require reporting of criminal charges.
- Auto insurance.
Expect rate increases of 60% to 100%, plus SR-22 requirements for three years in many cases. Some insurers may drop you completely.
- Immigration consequences.
For non-citizens, a DUI with aggravating factors can affect visa status, green card applications, and naturalization. Never plead to a DUI without immigration review if you’re not a U.S. citizen.
- Real-world dollar cost.
Studies estimate a single DUI can cost up to $30,000 when you add fines, court costs, insurance hikes, interlock installation ($75 to $150 per month), treatment programs, attorney fees, and lost wages from court dates (per 2025 data from Michael & Associates and national DUI cost studies).
License Suspension and the MVA Hearing Window
Your driver’s license is often the first thing you worry about after a DUI arrest. Here’s how license suspension works in Maryland.
Once the officer takes your license, you’ll receive a DR-15 Advice of Rights form and a temporary paper license valid for 45 days. During that window, you have only 10 days from the traffic stop to request an MVA hearing.
At the MVA hearing, an Administrative Law Judge reviews the case. They look at whether the officer had proper grounds to stop you, whether the breath or blood test was properly given, and whether you refused testing. Possible outcomes include no action, modified suspension, full suspension, or placement in the ignition interlock program.
Miss that 10-day window, and the suspension kicks in automatically on day 46. Miss it by even one day, and you lose the right to challenge the suspension.
This is why we urge clients to contact a DUI lawyer immediately after arrest, not after their first court date. The MVA side moves faster than the criminal side, and it’s often where your license battle is won or lost.
The Ignition Interlock Program Explained
Maryland’s ignition interlock program was strengthened by Noah’s Law, named after Montgomery County police officer Noah Leotta, who was killed by a repeat drunk driver in 2015.
An ignition interlock device is a breathalyzer installed in your vehicle. Before the engine starts, you blow into it. If it detects alcohol, the car won’t start. Random rolling tests happen while you drive, too.
Here’s how long you’ll typically need one.
| DUI Situation | Ignition Interlock Requirement |
|---|---|
| First DUI | 6 months |
| Second DUI | 1 year |
| Third DUI | 3 years |
| Drivers under 21 | Up to 3 years |
Since October 1, 2024, the ignition interlock requirement now also applies to PBJ dispositions. Before that date, a PBJ could help you avoid the device. That loophole has been closed.
Tampering with an interlock device is a separate criminal offense. Removing it, blowing around it, or having someone else blow for you all carry their own penalties.
Device installation runs between $75 and $150 per month, paid out of pocket. Successful completion of the program can sometimes lead to early license reinstatement.
Can You Fight DUI Charges in Maryland?
Yes. A DUI charge is not a DUI conviction. Our DUI defense attorneys review every angle of a case, and we often find weaknesses the prosecution missed.
Here are defenses that have worked in real Maryland courtrooms.
- Illegal traffic stop.
An officer needs articulable, reasonable suspicion to pull you over. If the stop was based on a hunch rather than a real legal reason, everything that followed can be thrown out.
- Field sobriety test problems.
The Standardized Field Sobriety Tests must be given in specific ways. Uneven pavement, medical conditions, bad footwear, or poor instructions all introduce error that your defense can use.
- Breath test issues.
Breath-testing devices in Maryland need regular calibration, and operators must be certified. Maintenance logs and operator records sometimes show real problems that call test results into question.
- Medical conditions.
Acid reflux (GERD), diabetes, and some neurological issues can mimic signs of impairment or skew breath readings.
- Rising BAC defense.
Alcohol absorption peaks later than many people realize. Your BAC at the time of driving may have been below the legal limit even if it tested higher later.
- Miranda and statement issues.
If you were questioned in custody without Miranda warnings, statements you made may be kept out of evidence.
Each of these defenses takes work, evidence, and experience. Not every case has every defense. But every case deserves a full review.
Why You Need a Maryland DUI Lawyer on Your Side
A DUI case is not something to face alone. The prosecution has a team. You should, too.
Here’s what a Maryland DUI lawyer does that you can’t do for yourself.
- Handles both tracks at once.
A DUI attorney manages the criminal case and the MVA license hearing in parallel, often negotiating with the State’s Attorney while also preparing your license defense.
- Knows the local courts.
Penalties and plea offers vary by county. Montgomery County doesn’t operate like Baltimore County, and the Eastern Shore has its own rhythm. An experienced DUI lawyer knows the players, the prosecutors, the judges, and the typical offers.
- Reviews the evidence.
Body-cam footage, dash-cam video, breath test calibration logs, officer training records, all of it is fair game. We know what to request and what to look for.
- Knows when to push and when to deal.
Sometimes the right move is trial. Sometimes it’s PBJ. But sometimes it’s a reduction from DUI to DWI, or from DWI to reckless driving. Reading each DUI case correctly takes years of experience.
At the Law Offices of Alex Poberesky, P.A., we’ve been defending Maryland drivers for more than 25 years. Our combined focus on criminal defense and personal injury law gives us a unique view of DUI and DWI cases in Maryland. We see them from every angle, including the ones that shape your future.
What to Do in the First 48 Hours After a DUI Arrest
The first two days after a DUI arrest are often the most helpful in building a strong defense. Here’s what we recommend.
- Write down everything you remember: the stop, the officer’s questions, the tests, and the timing. Details fade fast.
- Save any receipts (restaurants, Uber, pharmacy) that might help establish timing and your condition.
- Don’t post on social media. Anything you share publicly can be used against you later.
- Keep all paperwork. Your DR-15 Advice of Rights form, citations, and charging documents all matter.
- Mark the 10-day MVA request deadline on every calendar you have. Missing it means losing your license without a fight.
- Contact a Maryland DUI attorney before your first court date. The earlier, the better.
- Avoid talking about the case with insurance adjusters, employers, or investigators before speaking with counsel.
Small steps in the first 48 hours shape how the next six months play out.
Frequently Asked Questions About Maryland DUI Penalties
-
How long does a DUI stay on your record in Maryland?
A DUI conviction stays on your criminal record forever unless expunged, and expungement is rarely available for actual convictions. On your driving record, DUI points remain for two years from conviction. But the MVA and future employers can often see underlying convictions for much longer than two years.
-
Can a Maryland DUI be expunged?
Most DUI convictions can’t be expunged in Maryland. If you received Probation Before Judgment (PBJ), you may be able to expunge that disposition three years after probation ends, or sooner with good cause, under Maryland Code, Criminal Procedure § 10-105. An attorney can review your eligibility.
-
What happens if I refuse the breathalyzer in Maryland?
Refusing a breath test triggers an automatic 270-day license suspension for a first refusal and two years for a second. The prosecutor can also argue your refusal as evidence of guilt at trial, and the court can add two extra months of jail time and a $500 fine to any conviction.
-
Is a Maryland DUI a felony?
Most DUIs in Maryland are misdemeanors, not felonies. But aggravating circumstances like causing death or serious injury, or transporting a minor in some situations, can lead to felony charges under separate statutes. Vehicular manslaughter and life-threatening injury by motor vehicle are both felony-level offenses.
-
Can you get a DUI in a parked car in Maryland?
Yes. Maryland law covers anyone in “actual physical control” of a vehicle, not just people actively driving. Drivers have been convicted of DUI while sleeping in parked cars with keys in the ignition or the engine running. Whether you had physical control is a fact-specific question that the judge decides.
-
Do I have to take field sobriety tests in Maryland?
No. Field sobriety tests are voluntary in Maryland. Declining them does not trigger automatic license consequences the way refusing a chemical breath test does. Officers may still arrest you based on other observations, but you don’t have to help build the case against yourself.
-
How much does a DUI lawyer cost in Maryland?
Fees vary based on the case’s complexity, whether it goes to trial, and the attorney’s experience. Watch out for flat fees that seem too good to be true. The Law Offices of Alex Poberesky, P.A., offers a free case review so you can understand the likely costs before making any commitment.
