Mississippi DUI laws set the blood alcohol concentration limit at 0.08% for drivers 21 and older under Mississippi Code Section 63-11-30. A first offense carries fines from $250 to $1,000 and up to 48 hours in jail. A third offense within five years becomes a felony with fines from $2,000 to $5,000 and 1 to 5 years in custody. The law also covers license suspension, implied consent testing, and ignition interlock rules.
What Mississippi Law Defines as DUI
Mississippi Code Section 63-11-30 makes it unlawful to drive or operate a vehicle while under the influence of intoxicating liquor or any other substance that impairs a person’s ability to drive safely. The law also covers drivers under the influence of any drug or controlled substance unlawful to possess under the Mississippi Controlled Substances Law. A driver can be charged based on impairment or a measured blood alcohol concentration at or above the legal limit.
The statute applies regardless of whether a driver shows visible signs of impairment if a chemical test shows a blood alcohol concentration at or above the legal threshold for that driver’s category. This is often called a per se violation. Mississippi separates penalties by how many prior convictions a person has within a five year lookback period, with penalties increasing sharply for a second or third offense within that window.
BAC Limits By Driver Category
The standard blood alcohol concentration limit in Mississippi is 0.08% for a person who is above the legal age to purchase alcoholic beverages under state law. For a person below that legal purchase age, the limit drops to 0.02%, reflecting a zero tolerance approach for younger drivers. These thresholds apply to grams of alcohol per one hundred milliliters of blood or the breath equivalent measured through an approved chemical test.
Mississippi Code Section 63-11-30 on Justia Law confirms these blood alcohol concentration thresholds along with the penalty structure tied to each offense tier. The statute applies these limits uniformly across the state, so the same blood alcohol concentration threshold governs a DUI charge whether the stop happens in a rural county or a major city.
First Offense Penalties
A first DUI conviction in Mississippi is a misdemeanor under Code Section 63-11-30. The court may impose a fine of not less than $250 and not more than $1,000. The court may also impose imprisonment for not more than 48 hours in jail, or both a fine and jail time. The court may substitute attendance at a victim impact panel in place of the 48 hour jail term at its discretion.
A first offense also requires the person to attend and complete an alcohol safety education program under Code Section 63-11-32 within six months of sentencing. A qualifying first offense may be eligible for nonadjudication under Code Section 63-11-30, which is addressed later in this guide. Holders of a commercial driver’s license or a commercial learning permit at the time of the offense are not eligible for nonadjudication regardless of other qualifying factors.
Second Offense Penalties
A second DUI conviction within a five year period is a misdemeanor with substantially higher penalties than a first offense. The fine ranges from not less than $600 to not more than $1,500. The court must impose imprisonment of not less than 5 days and not more than 6 months, along with community service work of not less than 10 days and not more than 6 months.
These minimum penalties for a second offense cannot be suspended or reduced by the court. No prosecutor is permitted to offer a suspension or reduction of these minimum penalties as part of a plea bargain under Code Section 63-11-30. This mandatory minimum structure distinguishes second offense sentencing from the more flexible first offense framework, where the court retains broader discretion over the exact fine and whether jail time applies.
Third Offense And Felony DUI Penalties
A third DUI conviction within a five year period is classified as a felony under Mississippi law. The fine ranges from not less than $2,000 to not more than $5,000. A person convicted of a third offense must serve not less than 1 year and not more than 5 years in the custody of the Mississippi Department of Corrections. For an offense that does not result in serious injury or death, the court may allow the sentence to be served in the county jail rather than the state penitentiary.
As with the second offense penalties, the minimum fine and minimum term of custody for a third offense cannot be suspended or reduced by the court, and no prosecutor may offer a reduction of these minimums as part of a plea bargain. This felony classification reflects the state’s approach of escalating consequences sharply once a driver accumulates multiple convictions within the five year lookback period defined in the statute.
Implied Consent And Test Refusal Consequences
Mississippi operates under an implied consent law found in Code Section 63-11-23. Driving on Mississippi’s public highways, roads, and streets means a person has already agreed to submit to a chemical test of breath, blood, or urine when a law enforcement officer has reasonable grounds and probable cause to believe the person has been driving under the influence. This consent applies before any arrest occurs and does not depend on the driver’s willingness at the moment of the request.
If a person refuses to submit to the requested chemical test, and the officer confirms the person was informed that refusal would lead to suspension, the Commissioner of Public Safety must give notice of an administrative suspension. A first refusal results in a 90 day suspension if the person has no prior conviction under Code Section 63-11-30. A refusal by someone with a prior conviction under that section results in a 1 year suspension instead.
Mississippi Code Section 63-11-23 on Justia Law verifies that this refusal based suspension is a separate administrative track from any suspension tied to a DUI conviction itself. The administrative suspension for refusal begins 30 days after the date of the notice, giving the driver a limited window before the suspension period actually starts, and refusal related suspensions run consecutively rather than at the same time as other suspensions under the same chapter.
License Suspension Rules
License suspension in Mississippi generally follows the offense tier described in Code Section 63-11-30, with eligibility for an interlock restricted license and the length of suspension of regular driving privileges both governed by that section together with Code Section 63-11-23. Suspension of commercial driving privileges for a DUI conviction is instead governed separately by Code Section 63-1-216, which applies its own rules to commercial license holders.
A procedural change took effect through a 2023 amendment. Mississippi Legislature House Bill 253, 2023 Regular Session confirms the 120 day license suspension tied to a DUI conviction now begins on the date the judge signs the suspension order, rather than an earlier trigger date used under prior law. This affects when the suspension period starts running toward completion.
Suspension periods imposed for a DUI conviction under Code Section 63-11-30 are separate from any administrative suspension imposed under Code Section 63-11-23 for a chemical test refusal, and these suspensions run consecutively rather than concurrently. Laws and enforcement may change, so drivers should check official state sources for the latest rules on suspension timing and reinstatement requirements rather than relying solely on general summaries.
Nonadjudication And Alcohol Safety Education Requirements
A qualifying first offense DUI under Code Section 63-11-30 may be eligible for nonadjudication, a court process that can allow a person to avoid a formal conviction if specific conditions are met. Nonadjudication is not automatic and depends on the court’s determination that the person qualifies under the terms set out in the statute. Holders of a commercial driver’s license or commercial learning permit at the time of the offense are excluded from nonadjudication eligibility.
Every person convicted of a first offense DUI must attend and complete an alcohol safety education program under Code Section 63-11-32 within six months of sentencing, regardless of whether jail time or a fine is also imposed. This educational requirement functions independently of any fine or suspension and is treated as a mandatory condition of resolving a first offense DUI charge under Mississippi law.
Aggravated DUI And Child Endangerment
Mississippi law recognizes aggravated DUI as a distinct and more serious category of offense that applies when impaired driving causes death or serious bodily injury to another person. This classification carries penalties beyond the standard first, second, or third offense structure described earlier in this guide, reflecting the added harm involved when a DUI incident results in injury or loss of life to someone other than the driver.
Mississippi law also creates a separate offense for DUI child endangerment. A person over the age of 21 who violates the basic DUI prohibition while transporting a child under the age of 16 in the vehicle is guilty of a separate offense of endangering a child by driving under the influence. This offense exists independently of the underlying DUI charge and adds an additional layer of legal exposure specific to cases involving a minor passenger.
State Variations Note
Mississippi DUI law is governed entirely by Mississippi Code Title 63, Chapter 11, the Implied Consent Law, and does not mirror DUI statutes in other states. Blood alcohol concentration thresholds, fine ranges, jail exposure, and suspension timing described in this guide are specific to Mississippi and should not be assumed to apply the same way in any other state. A driver comparing DUI consequences across state lines should treat each state’s code as a separate legal framework entirely.
Mississippi Code Section 63-11-30 on FindLaw provides an additional cross reference confirming the offense tier structure described throughout this guide. Because penalties, suspension timing, and eligibility rules can be amended by the Mississippi Legislature, readers should treat this guide as general information rather than a final answer for any specific case, as explained further in the Disclaimer.
