A first DUI conviction in Mississippi means a fine of $250 to $1,000, up to 48 hours in jail, a required alcohol safety course called MASEP, and a 120-day license suspension unless you get an ignition-interlock-restricted license. That is Miss. Code § 63-11-30 and § 63-11-23 in plain English. Many first offenders qualify for non-adjudication, which keeps the conviction off their record entirely, and expungement can follow five years after the sentence is done. The window to act is short. Call early.
A first offense DUI under § 63-11-30(2)(a) is a misdemeanor. The penalty is a $250 to $1,000 fine, up to 48 hours in jail, or both, and the judge can substitute a victim impact panel for the jail time. The court must order MASEP within six months of sentencing. Your license is suspended for 120 days under § 63-11-23(5)(a)(i) unless you get an ignition-interlock-restricted license. For qualifying first offenders, non-adjudication under § 63-11-30(14) keeps the conviction off the record.
- Fine of $250 to $1,000, up to 48 hours in jail, or both
- MASEP alcohol safety course ordered within 6 months of sentencing
- 120-day license suspension, or an interlock-restricted license instead
- Non-adjudication is available once per lifetime for qualifying first offenders
- Expungement is possible 5 years after the sentence is complete
A First DUI Is Serious. It Is Also Survivable.
If you were arrested for DUI in Hattiesburg or anywhere in the Pine Belt, you are probably imagining the worst. A record. A lost license. A lost job. Take a breath. Mississippi law treats a first offense as a misdemeanor, and it builds in two exits that most people have never heard of: non-adjudication now and expungement later. Neither one happens automatically. Both have strict conditions, and some of those conditions are decided by what you do in the first days after the arrest.
Our DUI defense team has handled these cases in the local courts for decades. This page walks you through what a first conviction actually costs, how the off-ramps work, and why the calendar matters. If you were just arrested, start with our guide to the first 48 hours after an arrest in Mississippi, then call us at (601) 582-5015.
What a First DUI Conviction Actually Costs
Mississippi Code § 63-11-30(2)(a) sets the penalties for a first conviction. Here they are, piece by piece.
$250 to $1,000. The judge picks the number within that range. It is real money, but it is the most predictable part of the sentence, and it is often the part people worry about least once they see the rest.
Up to 48 hours. The statute allows the fine, the jail time, or both. The court may substitute attendance at a victim impact panel for the 48 hours. In practice, many first offenders never serve additional jail time after the night of the arrest.
Required, not optional. The court must order you to complete the Mississippi Alcohol Safety Education Program under § 63-11-32 within six months of sentencing. Skipping it puts everything else at risk, including non-adjudication.
120 days, or an interlock. § 63-11-23(5)(a)(i) suspends your license for 120 days unless you get an ignition-interlock-restricted license. The deadlines around this move fast. See our full guide to Mississippi DUI license suspension.
The Non-Adjudication Path: One Chance, Ever
Non-adjudication is the most valuable tool in a first offense DUI case, and it is the one most people have never heard of before they sit in our office. Under § 63-11-30(14), the court can accept your plea but withhold the conviction. You complete a list of conditions. If you finish them all, the case ends without a DUI conviction on your record.
The conditions are specific. You must complete every term the court sets. You pay a $250 non-adjudication fee under § 63-11-31(2)(b)(ii), plus all fines the court imposes. You finish MASEP within six months. And you still deal with your license: 120 days with an ignition-interlock-restricted license, or a 120-day suspension. Non-adjudication does not erase the license consequences. It erases the conviction.
Two hard limits. First, you get one non-adjudication per lifetime under any non-adjudication law, so using it is a decision to make with clear eyes. The state keeps a permanent registry of everyone who receives one. Second, it is not available to everyone. If you held a commercial driver's license at the time of the offense, you are not eligible. If you have a prior DUI, you are not eligible. For everyone else, it is the difference between a clean record and a permanent conviction, and it is worth fighting for.
Expungement After 5 Years: The Second Exit
Say you were convicted, or non-adjudication was not on the table. Mississippi still gives qualifying first offenders a second exit. Under § 63-11-30(13), you can petition the circuit court to expunge a first offense DUI conviction five years or more after you complete the full sentence.
The conditions are strict, and two of them are decided the night of the arrest. You must not have refused the breath test. And if you took the test, your BAC must have been below .16. You cannot fix either of those five years later. You must also have no other DUI conviction and no pending DUI charge, and no previous DUI non-adjudication or expungement. Like non-adjudication, this relief is once per lifetime, and it is not available to drivers who held a CDL at the time of the offense. The Department of Public Safety keeps a confidential registry of expunged offenses, but the public record is cleared.
Expungement petitions are their own court process with their own paperwork. We handle them regularly. Read more on our Mississippi expungement page.
Why the Charge Itself Is the Whole Fight
In many states, a DUI lawyer's first move is to bargain the charge down to reckless driving. Mississippi closed that door. § 63-11-39 forbids courts and prosecutors from reducing a DUI charge to a lesser charge. There is no wet reckless plea here. Period.
That changes the strategy completely. Since the charge cannot be traded down, the only question that matters is whether the state can prove it. Was the traffic stop lawful? Was the testing done by the book? Does the paperwork hold up? Those questions get harder for the state when a defense lawyer is asking them early, while evidence is fresh and witnesses remember. They get easier for the state every week you wait.
Hiring counsel early also protects the exits. Non-adjudication has filing requirements and deadlines. The interlock-restricted license has its own paperwork. Expungement eligibility turns on facts locked in at the start. A first offense is the case where early legal work pays off the most, because there is the most left to protect.
Where Your Case Will Be Heard in the Pine Belt
Where you were arrested decides your courtroom. An arrest inside the Hattiesburg city limits goes to Hattiesburg Municipal Court. An arrest out in the county, by a deputy or the highway patrol, goes to the justice court for that county, Forrest County Justice Court or Lamar County Justice Court for most of our clients. The charge is the same. The judges, prosecutors, and rhythms of each court are not, and knowing them matters.
One more piece of the safety net. If you are convicted in municipal or justice court, § 99-35-1 gives you 40 days to appeal to county court, where the case is tried de novo. That means a brand new trial, as if the first one never happened, with the judgment stayed while the appeal is pending. A cost bond between $100 and $1,000 is required. A conviction in a lower court is not the end of the road, but 40 days goes by fast.

First Offense DUI Questions We Hear Every Week
Will I go to jail for a first DUI in Mississippi?
Maybe, but not for long. A first offense under Mississippi Code § 63-11-30(2)(a) carries a fine of $250 to $1,000, up to 48 hours in jail, or both. The judge can also substitute attendance at a victim impact panel for the jail time. Many first offenders serve no jail time at all beyond the arrest itself.
Can I keep driving after a first DUI?
Your license is suspended for 120 days under Mississippi Code § 63-11-23(5)(a)(i). But the same statute gives you a way out. If you get an ignition-interlock-restricted license, you can keep driving during that period. The device goes on every vehicle you own or operate, and you pay the fees. For most working people, the interlock license is the difference between keeping a job and losing one.
What is non-adjudication for a Mississippi DUI?
Non-adjudication under Mississippi Code § 63-11-30(14) means the court accepts your plea but withholds a conviction. You complete the conditions, pay a $250 non-adjudication fee plus all fines, finish MASEP within six months, and serve 120 days either suspended or with an interlock-restricted license. If you do everything, no conviction goes on your record. You get one non-adjudication per lifetime under any non-adjudication law, and it is not available to CDL holders or anyone with a prior DUI.
Can a first DUI be expunged in Mississippi?
Yes, if you meet the conditions in Mississippi Code § 63-11-30(13). You can petition the circuit court five years or more after completing your sentence. You must not have refused the test, your BAC must have been below .16 if you were tested, you must have no other DUI conviction or pending charge, and no previous DUI non-adjudication or expungement. It is a once-per-lifetime relief, and it is not available to CDL holders. The Department of Public Safety keeps a confidential registry of expunged DUI offenses.
Can my DUI be reduced to reckless driving?
No. Mississippi Code § 63-11-39 forbids courts and prosecutors from reducing a DUI charge to a lesser charge. There is no Mississippi version of a wet reckless plea. That is why the fight is over the charge itself: the stop, the testing, and the proof. If the state cannot prove the DUI, the case fails. It cannot be traded down.
Do I need a lawyer for a first offense DUI?
You are allowed to handle it alone, but the deadlines and paperwork punish people who wait. Evidence needs to be requested early. Non-adjudication and the interlock-restricted license both require filings done right the first time. And because the charge cannot be reduced, the only leverage you have is a defense built on the facts. A lawyer who handles DUI cases in these courts knows where that leverage is.
