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 $2,000 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 becomes a felony in Maryland with up to 10 years of incarceration. 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.
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 5-Year Lookback and What Counts as a Prior
For enhanced sentencing, Maryland uses a 5-year lookback period. A prior DUI or DWI conviction within 5 years of the new offense triggers the second-offense penalty structure under Md. Code, Transp. § 27-101 and related provisions. The 5-year window is measured from the date of the prior conviction to the date of the new offense — not the new conviction.
Several rules about what counts as a prior:
- DWI counts as a prior. A prior DWI conviction within 5 years counts as a prior for purposes of enhancing a new DUI. The reverse is also true.
- PBJ on a prior generally does count. 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 purposes.
- Out-of-state DUI convictions count. A DUI conviction in any other state within the lookback period generally counts as a prior for Maryland sentencing purposes.
- Convictions older than 5 years still matter. Even if a prior is outside the 5-year window for mandatory-minimum purposes, the judge knows about it. It affects sentencing within the discretionary range, plea negotiations, and PBJ analysis.
The 10-year window for the PBJ bar (discussed below) is separate from the 5-year window for mandatory-minimum enhancements. Both 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 $2,000 fine (compared to $1,000);
- 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 — longer required period than first-offense;
- 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 fourth offenses.
Third-offense DUI within 5 years. Up to 3 years in jail, a $3,000 fine, mandatory minimum jail time at a higher floor than second offense, and increasingly difficult license consequences. The MVA administrative side imposes longer suspensions, and revocation becomes a near-certainty.
Fourth-offense DUI. A fourth DUI conviction in Maryland is a felony — escalated from the misdemeanor framework that applies to the first three. The maximum penalty is 10 years of incarceration. Felony classification carries additional collateral consequences: loss of certain civil rights, broader employment disqualification, and significantly more difficult license restoration.

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 critical for repeat-offense cases.
The practical effect: 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. See should I take the breathalyzer test in Maryland and first-offense DUI penalties in Maryland for context on how the PBJ option works in lower-tier 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 typically imposes a longer suspension period for a second-offense BAC failure or refusal compared to the first-offense schedule. Ignition Interlock Program participation may still be available as an alternative, but for a longer period — typically 1 year or more rather than the 6-month first-offense floor.
Third-offense and beyond. The administrative track moves toward outright revocation rather than time-limited suspension. License restoration becomes a multi-step process that can require Office of Administrative Hearings review, completion of treatment, sustained sobriety, and (often) extended interlock compliance even after the formal suspension period ends.
The 30-day window to request an MVA per se hearing applies to repeat-offense cases the same way it does to first-offense cases — and missing it forfeits the only opportunity to contest the administrative action. See the Maryland DUI MVA per se hearing.
The CDL Angle: Zero Tolerance 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.
