Refusing a Breathalyzer in Mississippi: License Suspension and Legal Options

Current as of: October 1, 2026 Criminal Defense Mississippi
In Mississippi, refusing a breathalyzer under the Implied Consent Law results in an automatic 90-day suspension of your driver's license for a first offense. You can legally challenge this suspension or install an Ignition Interlock Device (IID) to continue driving immediately.

When you see flashing blue lights in your rearview mirror after a night out in Biloxi, Southaven, or Jackson, panic naturally sets in. If the police officer suspects you of driving under the influence, they will ask you to blow into a breathalyzer machine. Many drivers believe that refusing this test is the smartest way to avoid giving the police evidence. However, Mississippi law is designed to heavily penalize drivers who refuse chemical testing. Understanding the consequences of a refusal and knowing your immediate legal options is critical to keeping your ability to drive to work and provide for your family.

The Mississippi Implied Consent Law

When you signed for your Mississippi driver's license, you legally agreed to submit to a chemical test of your breath, blood, or urine if an officer has reasonable grounds to suspect you of a DUI. This is known as the Implied Consent Law, governed by Miss. Code Ann. § 63-11-5. The officer must explicitly warn you about the penalties of refusing the test. This warning standard was heavily scrutinized in the precedent-setting case Lavinghouse v. Miss. Highway Safety Patrol, 620 So. 2d 971 (MS Supreme Court 1993), which states that if the officer fails to properly read your rights, the refusal suspension might be overturned in court.

Automatic 90-Day Suspension

If you refuse the official Intoxilyzer machine at the police station (not the portable breath test on the side of the road), you will face an administrative penalty entirely separate from your criminal DUI charge. Under Miss. Code Ann. § 63-11-21, a first-time refusal results in an automatic 90-day suspension of your regular driver's license. If you have a prior DUI conviction or a prior refusal on your record, the suspension period jumps to a devastating one year.

Forced Blood Draws in Felony Cases

While you have the right to refuse a breathalyzer in a standard misdemeanor DUI stop, that right evaporates if the situation involves a felony. If your DUI involves a serious bodily injury or a fatality, Mississippi law allows law enforcement officers to obtain a search warrant to physically force a blood draw against your will. They will transport you to a hospital, and medical staff will extract your blood, which will be sent to the state crime lab for alcohol and drug analysis.

Defending Against Faulty Intoxilyzer 8000 Machines

Sometimes drivers refuse because they distrust the machine. Mississippi predominantly uses the Intoxilyzer 8000 for official evidentiary breath tests. These machines must be strictly calibrated and maintained by certified operators. A skilled DUI defense attorney can subpoena the maintenance logs of the specific machine used in your case. If the machine was overdue for calibration or if the officer was not properly certified to operate it, your attorney can file a motion to suppress the results, turning a potentially weak refusal case into a strong defense.

Step-by-Step Process After Refusing a Breathalyzer in Mississippi

If you refused the test, the officer likely confiscated your physical driver's license and handed you a temporary driving permit. You must act quickly.

Step 1: Timelines to Request an Administrative Hearing

Under Miss. Code Ann. § 63-11-23, your temporary permit is valid for 30 to 45 days while the Commissioner of Public Safety reviews the officer's sworn report. If the suspension is sustained, you have exactly 10 days from the rendition of that decision to challenge it under Miss. Code Ann. § 63-11-25. Your attorney must file a Petition for Judicial Review in the circuit court or county court having jurisdiction, serving copies on the Attorney General and the Mississippi Department of Public Safety, Jackson. If you miss this 10-day window, you forfeit your right to appeal, and the 90-day suspension will take full effect once your temporary permit expires.

Step 2: Installing an Ignition Interlock Device (IID) to Drive Immediately

Mississippi offers a lifeline for drivers who refused the test but still need to get to work. Under state law, you can opt to waive your right to contest the suspension and immediately install an Ignition Interlock Device (IID) in your vehicle. By installing this device, which requires you to blow a clean breath sample before the car will start, you can obtain an Interlock Restricted License. This allows you to drive legally throughout your 90-day suspension period without any route or time restrictions.

Step 3: Fighting the Suspension in Court

If you appeal, your attorney will represent you at the judicial review hearing, which proceeds as a trial de novo before the court without a jury. Your attorney will cross-examine the arresting officer to determine if the traffic stop was constitutional and if they had actual probable cause to suspect you of impairment. If your attorney wins the court hearing, your driving privileges are fully restored while you wait to fight the criminal DUI charge in a court such as the Madison County Justice Court, Canton or the Harrison County Justice Court, Gulfport.

How Much Does it Cost in Mississippi?

Dealing with a refusal involves both administrative costs and legal fees.

  • IID Installation and Leasing: If you choose the Ignition Interlock option, installation typically costs around $100 to $150, followed by a monthly leasing and monitoring fee of $75 to $100 for the duration of the 90 days.
  • DPS Reinstatement Fee: To get your standard license back after the suspension period, you must pay a reinstatement fee of $175 to the Mississippi DPS.
  • Lawyer Fees: Hiring a local DUI defense attorney generally ranges from $2,000 to $5,000. This fee covers representation at both the administrative license hearing and the criminal court proceedings.

How Long Does the Process Take?

The administrative and judicial appeal process moves quickly. The temporary driving permit handed to you by the officer is valid for 30 to 45 days while the Commissioner reviews the refusal report. If the suspension is sustained, you have 10 days to petition the court for review. If an appeal is filed, the court hearing is typically scheduled within several weeks. If you lose or fail to appeal, your 90-day suspension takes effect. The actual criminal DUI trial can take much longer, often stretching 4 to 8 months depending on the court's docket.

Frequently Asked Questions (FAQ)

Does refusing the breathalyzer guarantee my DUI will be dismissed?

No. While refusing the test deprives the state of a specific BAC number, prosecutors can still convict you of a 'Common Law DUI' based on the officer's observations, such as slurred speech, failure of field sobriety tests, and dashcam video.

Can I refuse the portable breath test on the side of the road?

Yes. The handheld portable breath test (PBT) used on the side of the road is generally not admissible in court for an exact BAC reading. Refusing the PBT does not trigger the automatic 90-day suspension; that penalty only applies to the official machine at the police station.

Will the jury know that I refused the test?

Yes. Under Mississippi law, the prosecutor is allowed to tell the judge or jury that you refused the breathalyzer, and they may argue that your refusal shows a 'consciousness of guilt' because you knew you were intoxicated.

Can out-of-state drivers use the Ignition Interlock option in Mississippi?

Generally, out-of-state drivers cannot obtain a Mississippi Interlock Restricted License because Mississippi does not control their home state's driver's license. The refusal will be reported back to your home state, which will enforce its own suspension rules.
