A DUI charge in Mississippi can happen to anyone, and it moves fast. From the moment you are pulled over, the state begins building a case against you. Without skilled legal representation, you could face consequences affecting your job, insurance, professional licenses, driving privileges, and freedom.

At Tollison & Webb P.A., we defend clients charged with DUI in Oxford, Lafayette County, and throughout North Mississippi. We know Mississippi DUI law, the local courts, and how to identify weaknesses in the state’s case. If you have been charged with DUI, call us before you take the next step.

Mississippi DUI Laws — What You Need to Know

Mississippi law prohibits driving or otherwise operating a vehicle while impaired by alcohol, drugs, or another impairing substance. The per-se blood-alcohol concentration (BAC) limits are:

0.08% or higher for drivers who are legally old enough to purchase alcohol
0.02% or higher, but below 0.08%, under Mississippi’s zero-tolerance provision for drivers under 21
0.04% or higher while operating a commercial motor vehicle

Important for CDL holders: The 0.04% threshold applies when the person is operating a commercial motor vehicle. Even when a DUI occurs in a personal vehicle, however, a first DUI conviction disqualifies a CDL holder from operating commercial motor vehicles for one year. A first major offense while transporting placarded hazardous materials carries a three-year commercial-driving disqualification, and a second separate major offense generally carries a lifetime disqualification. There is no hardship privilege to operate a commercial motor vehicle during a disqualification.

The state does not need a BAC result to bring a DUI charge. A prosecution may instead rely on driving behavior, officer observations, field-sobriety testing, statements, and other evidence. A defense therefore requires review of both any chemical test and the circumstances surrounding the stop and arrest.

Penalties for a DUI Conviction in Mississippi

These are the principal baseline penalties for adult, non-commercial driving offenses under Miss. Code Ann. § 63-11-30. Separate and substantially greater penalties apply when DUI causes death, mutilation, disfigurement, or other serious injury, and Mississippi also recognizes a separate DUI child-endangerment offense. Other consequences can apply when a driver refuses chemical testing or another enhancement applies.

First Offense:

Fine of $250 to $1,000, up to 48 hours in jail, or both
The court may substitute attendance at a victim-impact panel for the jail term
Required completion of the Mississippi Alcohol Safety Education Program within six months of sentencing
120-day Class R license suspension unless the court orders an ignition-interlock-restricted license

Second Offense Within Five Years:

Fine of $600 to $1,500
Five days to six months in jail
Ten days to six months of community service
One-year Class R license suspension unless the court orders an ignition-interlock-restricted license
In-depth diagnostic assessment and, if indicated, completion of a certified alcohol- or drug-treatment program

Third Offense Within Five Years:

Felony conviction
Fine of $2,000 to $5,000
One to five years in custody
Suspension of regular driving privileges for the full sentence, followed by eligibility only for an ignition-interlock-restricted license for three years after release
In-depth diagnostic assessment and, if indicated, completion of a certified alcohol- or drug-treatment program

Fourth or Subsequent Offense, Regardless of When the Prior Offenses Occurred:

Felony conviction
Fine of $3,000 to $10,000
Two to ten years in custody
Suspension of regular driving privileges for the full sentence, followed by eligibility only for an ignition-interlock-restricted license for ten years after release
In-depth diagnostic assessment and, if indicated, completion of a certified alcohol- or drug-treatment program

For a second or subsequent conviction, vehicles owned by the offender that are not equipped with an ignition-interlock device must be impounded or immobilized pending further court order. This is different from the former description of automatic vehicle seizure and sale.

When the suspension begins: The first day of a 120-day suspension begins 21 days after the court enters the judgment of conviction or the order of nonadjudication, including a judgment entered following a guilty plea. Refusal-related administrative suspensions follow separate notice rules.

Field Sobriety Tests and Chemical Tests — Know Your Rights

Understanding what you are and are not required to do during a DUI stop is critical.

Field Sobriety Tests

Roadside field-sobriety exercises, including the walk-and-turn, one-leg stand, and horizontal-gaze-nystagmus test, are generally voluntary in Mississippi. The results can be affected by nervousness, medical or physical conditions, uneven pavement, lighting, footwear, and the officer’s instructions and scoring. An attorney should review the video and the way each exercise was administered before accepting the officer’s conclusions.

Breath, Blood, and Urine Tests

Driving on Mississippi public roads carries implied consent to chemical testing under the conditions set by law. Refusing a requested chemical test can produce a separate administrative suspension. A first refusal, when the driver has no prior DUI conviction or nonadjudication, generally carries a 90-day Class R suspension beginning 30 days after DPS notice. A driver with a prior DUI conviction or nonadjudication generally faces a one-year Class R suspension. Refusal by a CDL holder carries a one-year commercial-driving disqualification. A refusal does not prevent a DUI charge and may be admitted as evidence.

Submitting to a chemical test does not make the result conclusive. We examine whether the test was lawfully requested, whether approved procedures were followed, whether the instrument and operator met applicable requirements, and whether blood or urine samples were properly collected, preserved, and accounted for.

DUI Defenses We Evaluate

Every defense depends on the facts. We review the stop, detention, arrest, testing, recordings, reports, and witness accounts. Issues can include:

Unlawful Traffic Stop

Outside a lawful checkpoint, an officer generally must have reasonable suspicion for a traffic stop. Evidence obtained through an unlawful stop may be subject to suppression, which can materially affect the prosecution.

Statements and Miranda

Miranda applies to custodial interrogation. If statements were obtained in violation of those protections, the statements may be inadmissible. The effect depends on what was said, when it was said, and what other evidence exists.

Testing and Administration Errors

Chemical-testing instruments and operators must satisfy applicable requirements, and standardized field-sobriety exercises should be administered and scored correctly. Problems with maintenance, certification, observation periods, collection, preservation, or administration may affect reliability or admissibility.

Medical and Physical Conditions

Some medical or physical conditions can resemble signs of impairment or affect testing and roadside exercises. Medical records and qualified expert review may provide a basis to challenge the state’s interpretation of the evidence.

Checkpoint Violations

DUI checkpoints are permitted in Mississippi, but constitutional limits still apply. We examine the checkpoint plan, supervisory controls, selection procedure, notice, detention, and the conduct of the individual stop.

DUI Charges and Ole Miss Students

Oxford is home to the University of Mississippi, and a DUI charge can create issues beyond criminal court, including university discipline, professional-school applications, financial-aid questions, and housing or employment consequences. Those collateral issues depend on the student’s circumstances and the applicable university or program rules.

We regularly represent Ole Miss students facing DUI charges and consider both the criminal case and the academic or professional consequences when advising a client.

Mississippi’s Zero-Tolerance Law for Drivers Under 21

For a driver under 21, a BAC of at least 0.02% but below 0.08% falls under Mississippi’s zero-tolerance provision. A first conviction carries a $250 fine, completion of the alcohol-safety education program, and a 120-day license suspension unless an ignition-interlock option applies. At 0.08% or above, the regular DUI provisions apply.

Nonadjudication for a Qualifying First Offense

Mississippi provides a one-time nonadjudication option for some qualifying first offenses, including qualifying zero-tolerance cases. The court withholds adjudication while the person completes the statutory conditions. Those conditions include the applicable payments and completion of the alcohol-safety education program. In an alcohol-related case, the person must either use an ignition-interlock-restricted license for 120 days or serve a 120-day suspension with no driving. In a drug-related case, the person must either complete a 120-day period of court-ordered drug testing or serve a 120-day suspension with no driving. The court may impose other lawful conditions.

Nonadjudication is discretionary, is available only once, and is unavailable to anyone who held a CDL or commercial learner’s permit at the time of the offense. Successful completion prevents entry of a conviction, but DPS permanently retains the disposition in a confidential registry. Nonadjudication does not erase every record automatically, so eligibility and the effect of the disposition should be evaluated before a plea is entered.

Frequently Asked Questions

What is nonadjudication, and do I qualify?

Nonadjudication allows the court to withhold adjudication of guilt while an eligible first offender completes the statutory program. It is not automatic and must be approved by the court. A person generally must have no prior DUI conviction, no pending former or subsequent DUI charge, and no prior use of a DUI nonadjudication. A person who held a CDL or commercial learner’s permit at the time of the offense is not eligible.

Can a DUI be expunged in Mississippi?

Mississippi’s DUI-specific expunction provision applies to certain first-offense convictions. A qualifying person may petition the circuit court at least five years after successfully completing every term of the sentence. Eligibility is limited and includes requirements concerning CDL status, test refusal, BAC, other DUI matters, and any prior DUI nonadjudication or expunction. An expunction is not automatic, and nonadjudication is a separate disposition.

Can I refuse a chemical test in Mississippi?

A person can refuse, but the refusal can trigger a separate administrative suspension and may be used as evidence. For a Class R license, the suspension is 90 days if the person has no prior DUI conviction or nonadjudication and one year if the person does. A CDL holder faces a one-year commercial-driving disqualification for a first refusal. The facts and timing of the request matter, so legal advice should be specific to the stop.

Will a DUI show up on a background check?

A DUI conviction can appear on criminal background checks. Nonadjudication withholds a conviction, but that does not justify a blanket promise that every arrest, court, or agency record will disappear from every search. The public-record effect depends on the disposition, the records searched, and whether an expunction order applies.

How are prior DUI offenses counted in Mississippi?

The second- and third-offense provisions use a five-year period. A fourth or subsequent DUI is treated as such without regard to when the prior violations occurred. Mississippi also maintains a confidential registry of DUI nonadjudications and expunctions for eligibility and offender-status decisions.

Do I need a lawyer for a first-offense DUI?

A first offense can carry jail, a fine, an education requirement, license consequences, and collateral effects. Early review also matters because deadlines and strategic choices concerning testing, driving privileges, nonadjudication, and trial can arise quickly.
