Driving under the influence of alcohol or drugs (DUI) is dangerous. As a result, a DUI conviction carries a long-lasting impact. In Mississippi, you will lose your driver's license, pay thousands in fines and fees, and may even spend time in jail. Years later, a DUI conviction on your record can prevent you from getting certain jobs or attending college and may exclude you from housing.
The following is an overview of the basics of Mississippi DUI laws:

Mississippi Driving Under the Influence Law
The state of Mississippi prohibits anyone from operating or driving a vehicle while under the influence of:
- Alcohol or intoxicating liquor
- A substance that impairs your ability to drive or operate a motor vehicle
- A drug or illegal controlled substance
- Alcohol with a blood alcohol concentration (BAC) of 0.08% or 0.04% if operating a commercial vehicle
Mississippi law defines intoxication as an impairment of your "normal ability for clarity and control" that prevents you from operating or driving a motor vehicle safely.
Per Se DUI Offense
Mississippi recognizes a per se DUI offense. A per se offense says you are legally intoxicated if your BAC is at or above the legal limit of 0.08%. You don't have to show any impairment. You may be driving safely and not feel intoxicated. A chemical test proving you are at the per se limit is enough to prosecute you for a DUI.
Implied Consent Law for Chemical Testing
When you drive on roads in Mississippi, you have essentially agreed to chemical tests when a police officer suspects you of drugged or drunk driving. This is an implied consent law.
Law enforcement will ask you to submit to a Breathalyzer or breath test to determine your blood alcohol content. If arrested, law enforcement will ask you to participate in a blood test or urine or saliva analysis. These chemical tests determine your BAC and look for intoxicating substances.
You may refuse to cooperate with chemical tests. However, as the officer will tell you, there are immediate penalties for your refusal. You lose your driver's license for 90 days for a first offense. If you have a second refusal, your suspension period is for one year. A suspension for chemical test refusal is separate from any suspension if convicted. You must serve both suspension periods.
Aggravated DUI
If you cause the death, disfigurement, or serious bodily harm to another person, you will face a felony aggravated DUI charge — one separate charge for each person affected.
Conviction will earn you two to five years in prison. After your release, the Mississippi Department of Public Safety will require you to maintain an ignition interlock device for five years.
Mississippi is one of the few states that does not impose increased punishment for drivers with a high BAC unless you're a commercial driver. If you operate a commercial vehicle with a BAC of 0.08% or greater, you will face two to 10 years in prison.
DUI Child Endangerment
If you are 21 or older and are transporting a minor, age 16 or younger, the officer will charge you with child endangerment DUI. So long as the child is not injured, you face penalties, including a $1,000 fine and 12 months in jail for a first offense.
DUI Penalties
A DUI arrest and prosecution carries both criminal and administrative consequences. You will deal with the court system and the Mississippi Department of Public Safety if charged with a DUI.
Criminal Penalties
If convicted of a DUI, you will face multiple penalties. A first and second DUI within five years is a misdemeanor charge. A third and subsequent offense is a felony. If you are 21 or older, with no aggravating factors, your penalties can include the following elements.
First offense penalties:
- $250 to $1,000 fine
- Up to 48 hours of jail time
- Completion of the Mississippi Alcohol Safety Education Program (MASEP)
- Attendance at a victim impact panel
Second offense penalties within five years of a first DUI:
- $600 to $1,500 fine
- Minimum of five days, up to six months in jail
- Complete a substance abuse diagnostic assessment and treatment program as ordered
- 10 days to six months of community service
- No charge reduction or suspended sentences allowed
Penalties for a third offense:
- $2,000 to $5,000 fine
- Minimum of one year in jail, with up to five years possible
- Complete a substance abuse diagnostic assessment and treatment program as ordered
- No charge reduction or suspended sentences allowed
Non-Adjudication
A first-time DUI charge may be eligible for a non-adjudication. Under the non-adjudication program, you will enter a plea of guilty with the court. The judge then orders you to complete the program requirements. If you do so successfully, your DUI charge will not become a conviction on your criminal record.
Under the non-adjudication program, you must:
- Pay all fees associated with the program
- Pay a fine between $250 and $1,000
- Complete the Mississippi Alcohol Safety Education Program (MASEP)
- Install and maintain an ignition interlock device for 120 days
- Attend a victim impact panel
- Complete random drug and alcohol testing if ordered
- Commit no new traffic violations
To qualify, you must have cooperated with chemical testing. No aggravating factors should apply to your DUI charge. You can only participate in the program once.
The court will enter your guilty plea if you fail to complete the requirements for a non-adjudication finding. The judge will sentence you as with a first offense DUI.
Administrative Penalties and Driving Privileges
When convicted of a DUI, part of your sentence will include suspension of your driver's license.
For a first DUI, your suspension period is 120 days. You must complete your MASEP course and other requirements before your license is eligible for reinstatement. A judge may allow you a hardship license with an ignition interlock device requirement.
For a second DUI, your license suspension is for one year. Again, a judge may allow you limited driving privileges with an ignition interlock installed in your vehicle.
Ignition Interlock Device
An ignition interlock device (IID) is a small breath test that connects to your vehicle's ignition system. You must supply a breath sample before you can start your car. If the device detects alcohol in your system, the device will lock the ignition.
As you drive, the IID will randomly ask you to retest to ensure your sobriety.
After a second DUI offense, any vehicle not equipped with IID may face impoundment.
Tampering with the IID, driving a vehicle with an IID, or otherwise attempting to dodge your responsibilities under your IID order is a misdemeanor.
Zero Tolerance for Underage DUI
Mississippi has a zero-tolerance law for underage DUI offenses. If you are under 21 and drive with a BAC of 0.02%, law enforcement can charge you with a DUI. A conviction for a first offense with a BAC under 0.08% will cost you a $250 fine. You must complete a MASEP course and attend a victim impact panel. Your driver's license suspension is for 120 days.
If chemical tests show your BAC to be 0.08% or more, you face an adult DUI charge and penalties.
