Whether you will go to jail for driving drunk in Maryland depends on the charge and your record. A first-offense DUI under Md. Code, Transp. § 21-902 is a misdemeanor carrying up to one year in jail and a fine of up to $1,200 (raised from $1,000 effective June 1, 2025) — but jail is uncommon for a first offense with no aggravating facts. A first DWI, the lesser charge, carries up to 60 days. A second DUI within five years, however, carries a mandatory minimum of five days, and jail becomes far more likely with a high BAC, an accident, injuries, or prior offenses.
Most people charged with a first-time DUI and no accident are not sentenced to jail — but “unlikely” is not “impossible,” and the outcome turns on specifics a judge weighs at sentencing. Understanding what actually drives a jail sentence in Maryland, and what keeps one off the table, is more useful than a yes-or-no answer. It also explains why how the case is handled — trial, reduction, or probation before judgment — often matters more than the charge on its face.
The Honest Answer: Possible, but Uncommon on a First Offense
For a first DUI with a clean record and no accident, a sentence of active jail time is the exception rather than the rule. Maryland law authorizes up to a year, but judges routinely impose probation, fines, and conditions like alcohol education or treatment instead of incarceration. The statutory maximum is a ceiling, not a default.
That said, no honest lawyer will promise you will avoid jail. A judge can impose up to the maximum even on a first offense if the facts are bad enough, and a defendant’s history is only one of several factors weighed at sentencing. The realistic message is this: a first-time, no-accident DUI usually resolves without jail, but the result is earned through how the case is handled — not guaranteed by the fact that it is your first.
DUI vs. DWI: The Charge Changes the Exposure
Maryland separates the two offenses by degree of impairment, and the jail exposure follows. A DUI (the more serious charge) carries up to one year on a first offense; a DWI (driving while impaired, the lesser charge) carries up to 60 days. Because a DWI requires only a lesser degree of impairment, it is also a common negotiated outcome — a DUI is sometimes reduced to a DWI, which lowers both the jail ceiling and the points. Our guide to the difference between a DUI and a DWI in Maryland breaks down how prosecutors and courts treat each.
One point that surprises people: both DUI and DWI are misdemeanors at every offense level in Maryland. Drunk driving becomes a felony only through separate statutes when it causes serious injury or death. So the question is rarely “felony or not” — it is how a misdemeanor is sentenced.
What Makes Jail More Likely
The facts that move a case toward incarceration are fairly consistent:
- Prior offenses. A second DUI within five years carries a mandatory minimum of five days, and the maximum rises to two years. Third and subsequent offenses climb from there.
- A high BAC. A result of 0.15 or higher signals heavy impairment and triggers tougher administrative consequences as well.
- An accident or injury. A crash, property damage, or anyone hurt makes a sentence of jail substantially more likely.
- A minor in the car. A passenger under 18 is a recognized enhancer that increases both the jail ceiling and the fine.
When several of these stack together, the “first offense, probably no jail” expectation no longer holds. These are also the cases where experienced defense work matters most.
Beyond Jail: Fines, Points, and Your License
Jail is only one piece. Effective June 1, 2025, Maryland raised the maximum DUI fines: up to $1,200 for a first offense and $2,400 for a second (a DWI tops out at $500). Many older articles still cite the prior $1,000 and $2,000 figures — those are out of date.
The license consequence is often the one people feel most. A DUI conviction adds 12 points to your record, which triggers revocation; a DWI adds 8. That is on top of a separate administrative suspension handled by the MVA. If you want to understand how those points translate into license actions, see our overview of Maryland’s point system. The financial and licensing fallout frequently outlasts any jail question entirely.
How People Avoid Jail: PBJ and a Real Defense
For many first-time offenders, the path away from jail runs through probation before judgment (PBJ). A PBJ lets the court impose probation and conditions without entering a conviction; complete the terms and you avoid a DUI conviction on your record. It is not automatic, you generally cannot get a second one within ten years, and the arrest still shows on your driving record — but it is often the difference-maker. Our guide to DUI plea options and PBJ in Maryland covers when it is realistic.
Beyond PBJ, the defense itself drives the outcome: challenging the stop, the testing, and the proof can lead to a reduction or dismissal. These cases range from very defensible to quite serious depending on what the evidence shows — which is exactly why a clear-eyed review of your specific facts beats any general prediction about jail.
