Mississippi has zero tolerance for underage drinking and driving. At .02, a level one drink can reach, a driver under 21 faces a DUI charge, a $250 fine, a mandatory alcohol safety course, and a 120-day license suspension. At .08 or higher, the same young driver faces full adult DUI penalties. A qualifying first offense can be non-adjudicated, which keeps a conviction off the record, but that option exists once in a lifetime. Do not let your child plead guilty before you talk to a lawyer.
Mississippi's Zero Tolerance for Minors law, § 63-11-30(3), sets the per se limit at .02 for drivers under 21. The law runs on two tracks. From .02 up to just under .08, zero tolerance penalties apply: a flat $250 fine, MASEP, and a 120-day suspension for a first offense. At .08 or higher, the underage driver is charged under the adult DUI law and faces adult penalties. Non-adjudication under § 63-11-30(14) can keep a qualifying first offense off the record, but only once in a lifetime.
- .02 is the limit for drivers under 21, not .08
- First offense: flat $250 fine, MASEP within 6 months, 120-day license suspension
- Second within 5 years: fine up to $500 and a 1-year suspension
- Third: fine up to $1,000, mandatory treatment, and 2 years or until age 21, whichever is longer
- At .08 or higher, full adult DUI penalties apply
- One-time non-adjudication can protect a qualifying first offense
When the Phone Rings at 2 A.M.
No parent forgets that call. Your son or daughter has been pulled over in Hattiesburg, blew a number you do not understand, and is sitting at a police station. The officer says DUI. Your kid swears it was one drink. Under Mississippi law, one drink can be enough.
We have sat across the table from a lot of scared families in this situation. Here is what we tell them: the charge is serious, but the law leaves a path to protect a young person's record if you act before the court date, not after. Our office handles underage DUI cases in Hattiesburg Municipal Court, the surrounding justice courts, and across the Pine Belt.
The Two-Track System for Drivers Under 21
The number on the breath test decides which set of penalties applies. The difference between .07 and .08 is the difference between a zero tolerance case and an adult DUI.
Zero tolerance under § 63-11-30(3). The penalties are lighter than adult DUI, but it is still a DUI charge with a license suspension attached. Most one-drink and two-drink cases land here.
Full adult penalties under subsection (2) of § 63-11-30. Fine of $250 to $1,000, up to 48 hours in jail, MASEP, and license consequences. Being under 21 does not soften anything at .08 or higher.
Zero Tolerance Penalties, Offense by Offense
Here is what § 63-11-30(3) and § 63-11-23(5)(b) lay out for underage drivers in the .02 to under .08 range.
A flat $250 fine, completion of MASEP, the Mississippi Alcohol Safety Education Program under § 63-11-32, within 6 months, and a 120-day license suspension.
A fine of up to $500 and a 1-year license suspension. The window matters: the five-year clock runs from the first offense, and it changes how the second is treated.
A fine of up to $1,000, mandatory in-depth assessment and treatment, and a suspension of 2 years or until age 21, whichever is longer.
An offender under the driving age gets no license until age 18 under § 63-11-30(9). A 15-year-old caught driving after drinking waits years for a first license.
One Shot to Protect the Record
Mississippi law gives a qualifying first offender a way through that does not leave a conviction behind. Non-adjudication under § 63-11-30(14) means the court withholds a finding of guilt while your child completes the conditions: the fees, MASEP, and the license requirements. Finish everything, and the case closes without a DUI conviction on the record.
Two things every parent should know. First, non-adjudication is available once per lifetime, under any non-adjudication law. Use it at 19 on a case that could have been beaten, and it is gone forever. Second, § 63-11-39 forbids reducing a DUI to a lesser charge, so there is no pleading down to a traffic ticket. The realistic choices are fight the case, seek non-adjudication, or take a conviction. That decision should be made with a lawyer, not at a clerk's window.
What Parents Should Do First
Call a lawyer before the court date. That is the single most important step, because the options narrow sharply after a guilty plea. Do not just mail in the fine. Have your child write down everything about the stop while it is fresh: where, when, what the officer said, what tests were given. Save every paper from the arrest, including the license receipt, since it works as a temporary permit for a limited time under § 63-11-23.
For college families, there is more at stake than the courtroom. Students at Southern Miss and William Carey can face school discipline processes on top of the court case, and scholarships can be affected by how the case resolves. Every school handles these matters its own way, so get advice about your specific situation early. If the arrest happened inside Hattiesburg city limits, the case is generally heard in Hattiesburg Municipal Court; outside the city, it lands in a county justice court. We work in both, and we know how these dockets move.

Frequently Asked Questions About Underage DUI in Mississippi
My kid blew a .05. Is that really a DUI?
Yes. Mississippi's zero tolerance law, Mississippi Code § 63-11-30(3), applies to drivers under 21 with a blood alcohol level of .02 up to just under .08. A .05 falls in that range. A first offense carries a $250 fine, a required alcohol safety course called MASEP, and a 120-day license suspension.
What if they blew a .09?
Then zero tolerance no longer applies. At .08 or higher, an underage driver is charged under the adult DUI law, subsection (2) of § 63-11-30, and faces the same penalties as any adult, including a fine of $250 to $1,000, up to 48 hours in jail, MASEP, and a license suspension.
Will this be on their record forever?
Not necessarily. A qualifying first offense can be non-adjudicated under § 63-11-30(14). The court withholds a conviction while your child completes the required conditions, and the case ends without a conviction on the record. The law allows this once in a lifetime, and the Department of Public Safety keeps a confidential registry of everyone who uses it.
Do they lose their license?
Yes, for a time. A first zero tolerance offense brings a 120-day suspension. A second within five years brings a one-year suspension. A third brings a suspension of two years or until age 21, whichever is longer. And a driver too young to hold a license gets no license until age 18.
What does zero tolerance actually mean?
It means the .08 adult limit does not apply to anyone under 21. The law sets the line at .02 for underage drivers, a level a single drink can reach. The name comes straight from the statute, which calls the .02 rule Zero Tolerance for Minors.
Should we just pay the fine and move on?
No. Paying the fine means pleading guilty, and § 63-11-39 does not allow a DUI to be reduced to a lesser charge, so what goes on the record stays a DUI. Pleading guilty without a lawyer can also waste the one-time non-adjudication option. Talk to a lawyer before the court date, not after.
