A second-offense Maryland DUI within 5 years carries a mandatory minimum 5 days in jail (10 days if the BAC was 0.15 or higher), a maximum of 2 years in jail, a $2,400 fine, and 12 MVA points. A third-offense DUI carries up to 3 years in jail and a $3,000 fine. A fourth-offense DUI carries up to 10 years and a $10,000 fine. The mandatory-minimum jail provisions distinguish repeat-offense cases from first-offense cases — judges cannot avoid the jail floor through suspended sentences or probation alone. Probation Before Judgment is also unavailable to most repeat offenders within the 10-year lookback period. Notably, Maryland DUI remains a misdemeanor at every offense count — felony elevation requires life-threatening injury or death under separate statutes.
A subsequent Maryland DUI is a fundamentally different case from a first offense. The starting point is not “can we avoid a conviction” — it is “how do we minimize jail time and protect what driving privileges remain.” Drivers facing a second or third DUI need to understand the lookback rules, the mandatory minimums, and the realistic outcomes before walking into court.
The Lookback Rules: 5 Years for Second, Lifetime for Third
Maryland uses two different lookback windows for sentencing enhancement on repeat DUI cases, and confusing them is one of the most common mistakes drivers make when assessing their case.
Second-offense determination: 5-year window. Under Md. Code, Transp. § 27-101 and § 21-902, a prior DUI or DWI conviction within 5 years of the new offense triggers the second-offense penalty structure, including the mandatory minimum jail. The 5-year window is measured from the date of the prior conviction to the date of the new offense.
Third-and-subsequent-offense determination: lifetime window. For determining whether an offense is a third or subsequent DUI/DWI, Maryland counts all prior DUI and DWI convictions regardless of age. A driver with a DUI from 12 years ago and another from 4 years ago who picks up a new DUI today is facing a third offense — not a second — even though one of the priors is well outside the 5-year window.
Several rules about what counts as a prior:
- DWI counts as a prior. A prior DWI conviction counts as a prior for purposes of enhancing a new DUI. The reverse is also true.
- PBJ on a prior generally counts as a prior. Even though a Probation Before Judgment is not a conviction in the traditional sense, Maryland law treats it as a prior alcohol-related disposition for sentencing enhancement and PBJ-bar purposes.
- Out-of-state DUI convictions count. A DUI conviction in any other state within the applicable lookback counts as a prior for Maryland sentencing purposes.
- Priors outside the 5-year window still matter for sentencing. Even if a prior is too old to trigger the second-offense mandatory minimum, the judge knows about it. It affects sentencing within the discretionary range and plea negotiations.
The 10-year window for the PBJ bar (discussed below) is a separate rule from both the 5-year and lifetime lookback windows. Multiple windows can apply to the same case.
Second-Offense DUI Penalties
The maximum penalties for a second-offense Maryland DUI conviction within 5 years are:
- Up to 2 years in jail (compared to 1 year for first offense);
- Up to a $2,400 fine — the cap increased from $2,000 to $2,400 effective June 1, 2025 (compared to $1,200 for first offense);
- Mandatory minimum 5 days in jail — the judge cannot suspend this portion;
- Mandatory minimum 10 days in jail if the BAC was 0.15 or higher;
- 12 MVA points (same as first offense);
- Mandatory ignition interlock for 1 year under Noah’s Law;
- Lengthier administrative license suspension through the MVA; and
- Mandatory completion of alcohol evaluation and any recommended treatment.
The mandatory minimum is the defining feature of the second-offense case. A first-offense Maryland DUI conviction can resolve with no active jail time — the maximum is a ceiling, not a floor. A second-offense DUI within 5 years cannot. The judge must impose at least the statutory minimum, and the only path to avoiding active jail is to push the case away from a second-offense conviction entirely — either through plea reduction to a DWI, dismissal of the new charge, or successful challenge to the prior.
Third and Fourth Offense DUI Penalties
The penalty structure escalates sharply for third and subsequent offenses — but the offense remains a misdemeanor at each level. Maryland DUI is not elevated to a felony based on prior-offense count alone. Felony elevation only occurs when the impaired driving causes life-threatening injury or death, which falls under separate statutes (vehicular manslaughter, life-threatening injury by vehicle).
Third-offense DUI. If a driver has two or more prior DUI or DWI convictions (regardless of how old, given the lifetime lookback for third-offense status), a new DUI carries up to 3 years in jail, a $3,000 fine, mandatory minimum jail time, and mandatory interlock for at least 3 years under Noah’s Law. The MVA administrative side moves toward outright revocation rather than time-limited suspension.
Fourth and subsequent offense DUI. A fourth or subsequent DUI conviction carries the highest statutory maximum — up to 10 years in jail and a $10,000 fine under the enhanced penalty provisions. Despite the severity of the penalties, the offense remains a misdemeanor under Maryland law. License restoration becomes a multi-step process that can require Office of Administrative Hearings review, completion of treatment, sustained sobriety, and extended interlock compliance.

PBJ Is Generally Unavailable: The 10-Year Bar
Maryland law generally prohibits a court from granting Probation Before Judgment for an alcohol-related driving offense if the defendant received a PBJ for any alcohol-related driving offense within the prior 10 years. The 10-year bar is hard and well-known to prosecutors and judges. Practical implications:
A driver who received a PBJ on a first-offense DUI eight years ago and is now charged with a new DUI cannot avoid the new conviction by another PBJ. The new case will resolve as either a conviction or as a dismissal — there is no middle ground for first-time repeat offenders.
This bar applies even though the original PBJ was not technically a conviction. Maryland law treats prior PBJs on alcohol-related offenses as bar-triggering events for purposes of PBJ availability on new alcohol cases.

License Consequences for Repeat Offenders
The MVA administrative side under Md. Code, Transp. § 16-205.1 escalates sharply for repeat offenders.
Second-offense administrative suspension. The MVA imposes a longer suspension period for a second-offense BAC failure or refusal compared to first-offense schedules. For BAC 0.15+ on a second offense, the suspension is 270 days. For a second or subsequent refusal, the suspension is 2 years. Ignition Interlock Program participation may still be available as an alternative for some categories, but typically for a longer period than for first offenses.
Third-offense and beyond. The administrative track moves toward outright revocation. License restoration becomes a multi-step process that often requires Office of Administrative Hearings review, completion of treatment, sustained sobriety, and extended interlock compliance even after the formal suspension period ends.
The 10-day window to preserve a temporary license through the MVA per se hearing — and the 30-day outer deadline to request the hearing at all — applies to repeat-offense cases the same way it does to first-offense cases. Missing these deadlines forfeits the only opportunity to contest the administrative action. See the Maryland DUI MVA per se hearing.
The CDL Angle: Lifetime Disqualification for Repeat CDL Violations
For commercial driver’s license holders, the consequences of a repeat alcohol-related conviction are severe. Federal regulations under 49 CFR Part 383 impose lifetime CDL disqualification for a second alcohol-related conviction — even if the second offense occurred in a personal vehicle. The home state cannot mask or hide the conviction; the Commercial Driver’s License Information System (CDLIS) tracks these convictions nationally.
For CDL drivers facing a second alcohol-related case, the CDL disqualification often matters more than the criminal penalty. See how Maryland DUI affects a CDL for the full federal framework.
Insurance and Collateral Consequences
After a second Maryland DUI conviction, most standard insurance carriers will not renew. Drivers are typically forced into the nonstandard (high-risk) insurance market with premiums that can be three to five times higher than standard-market rates. The increase persists for years and often outlives the formal license consequences of the case.
Other collateral consequences worth understanding:
- Employment. Background checks for any safety-sensitive position will show repeat DUI history. Many employers in transportation, healthcare, education, and security treat a second DUI as disqualifying.
- Travel. Canada and certain other countries treat any DUI as grounds for entry denial — and the analysis becomes harder with a repeat record.
- Professional licenses. Many state licensing boards (medical, legal, nursing, real estate, accounting) require self-reporting of DUI convictions. A second conviction can trigger disciplinary action that a first-offense PBJ would not have.
- Civil exposure. If an accident is involved, civil liability can be significantly higher than the criminal penalties — and a prior DUI in evidence makes the civil case much harder to defend.
Realistic Defense Strategies in Repeat-Offense Cases
Because PBJ is generally unavailable and the mandatory minimums apply, repeat-offense Maryland DUI cases focus on different goals than first-offense cases.
Challenge the new charge directly. The strongest outcome in a repeat case is dismissal or charge reduction of the new offense — not a managed conviction. That means examining the stop, the field evidence, the breath test, the implied consent advisement, and any procedural issues. If the State’s proof on the new charge is vulnerable, the priors become irrelevant.
Challenge the prior, where possible. A prior conviction that was obtained without proper representation, or that involved procedural defects, may be challengeable for sentencing-enhancement purposes. This is technical and case-specific, but it can be the difference between a mandatory-minimum case and a discretionary-sentence case.
Negotiate around the mandatory minimum. If a conviction on the new DUI is unavoidable, the negotiation shifts to managing the sentence within and around the mandatory floor — work release, home detention, weekend service, treatment placement in lieu of straight jail. These options are case-by-case and judge-dependent, but they meaningfully change what a sentence actually looks like in practice.
Sentencing mitigation. Demonstrating sustained sobriety, completed treatment, professional and family ties, and a credible plan for avoiding future contact with the system can affect how the judge sentences within the discretionary range above the mandatory floor.

A Subsequent DUI Carries Mandatory Jail — Don’t Face It Alone
A second or third DUI in Maryland is a different case from a first offense. Mandatory minimum jail time. No Probation Before Judgment. Substantially harder license consequences. Lifetime CDL disqualification for commercial drivers. The earlier the case is evaluated, the more options exist for challenging the new charge, attacking sentencing enhancements, and managing what a sentence actually looks like in practice.
