A first-offense Maryland DUI conviction under Md. Code, Transp. § 21-902(a) carries up to 1 year in jail, a $1,200 fine (Maryland increased the fine cap from $1,000 to $1,200 effective June 1, 2025), 12 MVA points, mandatory ignition interlock under Noah’s Law for many drivers, and lengthy administrative license suspension through the MVA. The maximum penalties are rarely the actual outcome — first-time offenders with clean records often resolve their cases through Probation Before Judgment or a plea reduction to DWI. But “first offense” does not mean “minor consequence.” A Maryland DUI on your record affects insurance, employment, and your license for years.
Drivers facing a first-offense DUI in Maryland often underestimate the case. The thinking goes: clean record, no accident, cooperative at the stop — surely this will be handled lightly. Sometimes it is. Often it is not. The actual outcome depends on the BAC reading, whether the breath test was refused, the field evidence, the court, and how prepared the driver is when the case is called.
The Criminal Penalties: Jail, Fine, and Points
Md. Code, Transp. § 21-902(a) and the related penalty provisions in § 27-101 set the maximum penalties for a first-offense DUI conviction:
- Jail: up to 1 year. Active jail time is unusual for genuinely first-offense, low-aggravation cases, but it remains in the judge’s discretion.
- Fine: up to $1,200, plus court costs (the cap increased from $1,000 to $1,200 effective June 1, 2025). The fine alone is rarely the most expensive part of the case.
- MVA points: 12 — enough to put the driver in revocation territory under Maryland’s point system.
- Criminal record: a misdemeanor conviction unless the case resolves with a PBJ or dismissal.
Several aggravators push first-offense cases toward the harsher end of the range: a BAC of 0.15 or higher, an accident (especially with injury), a child passenger under 16 (which triggers an enhancement under § 27-101(r) with maximums up to 2 years jail and a $2,000 fine for a first offense), refusal of the breath test combined with other evidence of impairment, or particularly egregious driving behavior on the stop. Any of these can transform what looks like a straightforward first DUI into a case with real jail exposure. See will I go to jail for driving drunk in Maryland for the jail-risk analysis in depth.
License Consequences: Administrative and Criminal
A Maryland DUI triggers license action on two separate tracks that run in parallel.
The MVA administrative track. Under Md. Code, Transp. § 16-205.1, the MVA imposes license action based on the BAC reading or breath test refusal — independently of the criminal case. For a first offense with BAC 0.08 to less than 0.15, the typical administrative suspension is 180 days (with the option to participate in the Ignition Interlock Program instead). For BAC 0.15 or higher, the suspension is also 180 days for a first offense, with a stronger interlock requirement. For breath test refusal on a first offense, the suspension is 270 days — or 1 year of mandatory interlock participation as an alternative.
The MVA per se hearing process operates on a strict two-deadline system that catches a lot of drivers off guard:
- 10 days — the critical deadline. Request the hearing within 10 days of the stop, and the MVA extends your temporary license through the hearing date. Most hearings are not held until 45+ days out, so this deadline is what protects your right to drive in the meantime.
- 30 days — the absolute outer deadline. A hearing requested between days 11 and 30 will still be granted, but the temporary license expires after 45 days and the administrative suspension begins before the hearing happens. A request postmarked after day 30 is denied entirely.
The 10-day deadline is often the most time-sensitive issue in the entire DUI case. Missing it forfeits the practical ability to keep driving between the stop and the hearing. For more on what the per se hearing actually involves, see the Maryland DUI MVA per se hearing.
The criminal track. If the case results in a DUI conviction, the 12 MVA points trigger automatic license action — at 12 points, revocation proceedings begin. Even a PBJ on a DUI typically results in administrative consequences from the MVA side that are not avoided by the criminal-side PBJ. Drivers often discover that a “successful” criminal resolution does not fully protect their license. See if my DUI is dropped, can the MVA still suspend my license for the full picture.
Ignition Interlock Under Noah’s Law
Maryland’s Noah’s Law, codified at Md. Code, Transp. § 16-404.1 and related provisions, made ignition interlock mandatory for many DUI convictions. Interlock is the device installed in the vehicle that requires a breath sample before the vehicle starts — and periodically while driving. A failed sample prevents starting and creates a record.
For a first-offense DUI conviction with BAC 0.08+, interlock is generally required for 6 months. For first-offense DUI with BAC 0.15 or higher, the requirement is 1 year. For first-offense breath test refusal in a DUI case, interlock is also typically 1 year. Drivers who participate in the Ignition Interlock Program can often avoid the longer administrative suspensions described above, in exchange for installing the device and complying with the program rules.
The interlock device costs the driver — installation, monthly leasing, and removal. Total cost over the required period typically runs $600 to $1,500 depending on the duration. Compliance also affects ongoing license restoration.
Probation Conditions and Monitoring
Most first-offense Maryland DUI cases result in some form of probation — either supervised or unsupervised. Typical probation conditions include:
- Completion of an alcohol evaluation, often followed by treatment if recommended;
- Attendance at a Victim Impact Panel (typically through MADD);
- No alcohol-related driving offenses during the probationary period;
- Compliance with the ignition interlock requirement; and
- Payment of fines, costs, and any restitution.
Violation of probation conditions exposes the driver to the original suspended jail time. For first-offense cases, that can mean active jail in a case that initially resolved without it.
PBJ Availability for First-Offense DUI
Probation Before Judgment under Maryland Code, Criminal Procedure § 6-220 is often the realistic goal in a first-offense DUI case. A successful PBJ:
- Avoids the criminal conviction (subject to disclosure exceptions for certain employment and licensing applications);
- Generally avoids the criminal-side MVA points;
- Substantially improves the insurance outcome compared to a conviction; and
- Allows the driver to truthfully say they were not convicted, in most contexts.
Maryland law generally prohibits a second PBJ for an alcohol-related driving offense within a 10-year period. That means a driver who used a PBJ on an earlier alcohol-related case cannot do it again. For first-time drivers with no prior alcohol case, PBJ is typically the realistic outcome to aim for — though it is not guaranteed and depends on the judge, the case facts, and the driver’s preparation.
Insurance, Employment, and Long-Term Consequences
The published penalties for a first-offense Maryland DUI rarely capture the full cost.
Insurance. A DUI conviction can produce premium increases that last 3 to 5 years and easily exceed the fine itself. Some carriers will not renew. Drivers may be forced into nonstandard (and significantly more expensive) coverage. A successful PBJ typically reduces this impact substantially.
Employment. A DUI conviction shows up on most background checks. Industries with safety-sensitive positions (transportation, healthcare, education, security clearance holders) may treat a DUI as a disqualifying or escalating factor. CDL holders face the most acute consequences — see how Maryland DUI affects a CDL.
Travel. Some countries (Canada in particular) treat a DUI conviction as grounds for denying entry. This is a hidden long-term cost that affects more drivers than expect it.
How to Position the Case for the Best Outcome
Three things matter early in a first-offense Maryland DUI case.
First, the 10-day MVA hearing deadline. The window to request a per se hearing in a way that preserves your temporary license is just 10 days from the date of the stop. Missing it forfeits the practical ability to drive between the stop and the hearing. This is often the most time-sensitive issue in the entire case.
Second, alcohol evaluation and any treatment program. A driver who walks into court with a completed evaluation and a treatment recommendation already underway presents very differently from a driver who shows up empty-handed. Judges weigh evidence of taking the matter seriously when deciding on PBJ and probation conditions.
Third, evidence review. The breath test calibration, officer certification, field sobriety test administration, and stop justification all matter. Defenses exist but are case-specific — a careful review of the discovery often surfaces issues that affect plea negotiations even if they do not lead to dismissal.

First Offense Doesn’t Mean Light Penalty — Get Counsel Early
A first-offense Maryland DUI is still a criminal misdemeanor with up to a year of jail exposure, mandatory ignition interlock, real license consequences, and insurance impact that lasts years. The 10-day MVA hearing deadline runs quickly after the stop. The earlier the case is evaluated, the more options you have — including a Probation Before Judgment that avoids the conviction entirely, or a plea reduction to DWI that cuts the penalties roughly in half.
