Mississippi's implied consent law, Miss. Code § 63-11-5, means that by driving on a public road you have already agreed to testing. Refuse the breath test and the officer takes your license on the spot. The suspension is 90 days with no prior, one year with one, and it takes effect 30 days after notice. It sits on top of any criminal penalty, the refusal itself is admissible at trial under Miss. Code § 63-11-41, and refusing quietly costs you the one-time first-offense expungement. You get 10 days to seek judicial review once the Commissioner sustains the suspension. That window closes fast.
Refusing the breath test does not make a Mississippi DUI case go away. It trades one problem for several. The state loses its breath number, but you lose your license through a separate administrative suspension, hand the prosecutor a piece of evidence, and give up a future expungement right most people do not know exists.
- Driving on Mississippi public roads means you have already consented to breath, blood, or urine testing (Miss. Code § 63-11-5)
- Refuse, and no breath test is given; the officer takes your license and issues a receipt (Miss. Code § 63-11-21)
- Suspension takes effect 30 days after notice: 90 days with no prior, 1 year with a prior conviction or non-adjudication
- The refusal suspension is in addition to any criminal DUI penalties
- The refusal is admissible against you in the criminal case (Miss. Code § 63-11-41)
- You have 10 days to petition for judicial review after the Commissioner sustains the suspension (Miss. Code § 63-11-25)
- Refusing disqualifies you from Mississippi's one-time first-offense DUI expungement
What Refusing the Breath Test Really Costs in Mississippi
It happens at midnight on Highway 49 or Hardy Street. The officer holds out the device and asks you to blow. You have heard from a friend, or a movie, that you should never take the test. So you refuse. Nobody at the roadside explains what that decision just set in motion.
Lowrey, Fortner, & Miri P.A. has defended DUI cases across the Pine Belt since 1980, from our office on Corinne Street in Hattiesburg. We handle both halves of a refusal case: the criminal DUI charge in court, and the administrative fight over your license. They run on different clocks, in front of different decision makers, and the license clock is the one that catches people off guard.
This page covers the refusal itself. For the wider picture, see our DUI defense hub, our guide to DUI license suspensions, and our first-offense DUI page. And if the arrest just happened, read what happens in the first 48 hours after a Mississippi arrest.
Implied Consent: The Deal You Already Made
Mississippi law treats driving as a bargain. Under Miss. Code § 63-11-5, anyone operating a motor vehicle on the public roads of this state is deemed to have given consent to a chemical test of their breath, blood, or urine. You agreed to it the moment you pulled out of the driveway. The statute also requires the officer to warn you of the price of backing out: a 90-day suspension for refusal, or one year if you have a prior.
Here is the part people find strange. If you refuse the breath test, the officer honors the refusal. Under Miss. Code § 63-11-21, none shall be given. There is no wrestling match at the station. The consequence is not the test. The consequence is everything that follows.
What Happens When You Refuse, Step by Step
The refusal process is administrative, paper-driven, and fast. Here is the sequence, from the roadside to the suspension.
On refusal, the officer takes your driver's license and hands you a receipt. That receipt is your proof of what happened and when. Keep it, photograph it, and bring it to your lawyer.
Under Miss. Code § 63-11-21, if you refuse the breath test, none is given. The state ends the night without a breath number, which is exactly why prosecutors lean so hard on the refusal itself later.
The officer submits a sworn report to the Commissioner of Public Safety describing the stop and the refusal. The Commissioner reviews that report. This is a paperwork proceeding. You are not in the room.
The suspension does not start the night of the arrest. It takes effect 30 days after you are given notice. That month is your planning window: rides to work, childcare, and the decision whether to fight.
With no prior DUI, the refusal suspension runs 90 days. With a prior conviction or non-adjudication on your record, it runs a full year. The prior does not have to be recent.
Under § 63-11-30(4), the refusal suspension is in addition to any criminal penalties. Win the DUI case or lose it, the refusal suspension is its own animal, decided on its own track.
The Refusal Follows You Into the Courtroom
A lot of people refuse because they believe it starves the state of evidence. Half true. The state has no breath number, but it gains something else: the refusal itself. Under Miss. Code § 63-11-41, evidence of your refusal is admissible in the criminal case. Expect the prosecutor to stand in front of the judge or jury and argue that you refused because you knew what the machine would say.
That argument can be met. There are innocent reasons people refuse: fear, confusion, bad advice absorbed years earlier, distrust of the machine. The officer's own video often helps tell that story. But it is a fight you should walk into with counsel, not a fight that wins itself. And through it all, the DUI charge continues. Refusing did not make it disappear.
The 10-Day Window to Fight the Suspension
The refusal suspension can be challenged, but Mississippi gives you a short runway. Under Miss. Code § 63-11-25, once the Commissioner sustains the suspension, you have 10 days to petition the circuit or county court for judicial review. Miss it, and the suspension simply runs.
The review is a trial de novo, meaning the court hears the matter fresh rather than rubber-stamping the paperwork, and there is no jury. One warning we give every client up front: you cannot drive while that appeal is pending. The decision to fight has to account for that.
For comparison, a driver who takes the test and fails it, .08 or higher, or .02 or higher under 21, is on a different track. The officer seizes the license, but the receipt serves as a 30-day temporary permit, and requesting a trial within 30 days can extend that permit until the case is finally decided. Refusal has no such cushion. The two tracks are easy to confuse, and our license suspension page lays them out side by side.
The Expungement Consequence Nobody Mentions
Here is the cost of refusal that almost never comes up at the roadside, and it may be the biggest one. Mississippi allows a one-time expungement of a first-offense DUI conviction under § 63-11-30(13). You petition the circuit court five or more years after completing the sentence, and if you qualify, the conviction comes off your record.
But look at the conditions. Among them: you did not refuse the test, and if you took it, your BAC was below .16. Refuse the breath test, and you have disqualified yourself from that expungement before the case has even started, no matter how the criminal charge turns out. Our first-offense DUI page covers the full list of requirements, and it is worth reading before you assume your record can be cleaned up later.
So, Should You Refuse the Breath Test?
We will not tell you what to do at a traffic stop that has not happened yet, and you should be suspicious of anyone who will. What we can do is put the tradeoffs on the table honestly.
Refusing means the state has no breath number to wave around. In exchange, you take a license suspension that stacks on top of whatever the criminal case brings, you hand the prosecutor an admissible refusal to argue about, and you surrender your one-time shot at first-offense expungement. Taking the test means the state gets its number, whatever that number turns out to be, and the administrative track gives you a 30-day permit with a way to extend it.
There is no answer that fits every person and every night. What is true in every case: the decisions made after the stop, starting with how fast you get a lawyer involved, matter enormously. If you already refused, the analysis is behind you and the deadlines are ahead of you. That is the moment to call.

Frequently Asked Questions About Breath Test Refusal in Mississippi
Can I refuse the breath test in Mississippi?
Physically, yes. If you refuse, no breath test is given, under Miss. Code § 63-11-21. But Mississippi's implied consent law, § 63-11-5, says that by driving on public roads you have already consented to testing, and the officer is required to warn you that refusal means a 90-day suspension, or one year if you have a prior. Refusing does not stop the DUI charge. It adds a separate license suspension on top of it.
What happens to my license if I refuse the breath test?
The officer takes your license on the spot and gives you a receipt. The officer then sends a sworn report to the Commissioner of Public Safety, who reviews it. The suspension takes effect 30 days after notice: 90 days if you have no prior DUI, or one year if you have a prior conviction or non-adjudication. This suspension is separate from, and in addition to, anything that happens in the criminal case.
Can my refusal be used against me in court?
Yes. Under Miss. Code § 63-11-41, evidence that you refused the test is admissible in the criminal DUI case. Prosecutors routinely argue that refusal shows you knew you would fail. A defense lawyer can push back on that story, but you should expect the refusal to come into evidence.
Does refusing the breath test help my case?
It cuts both ways, and anyone who gives you a one-word answer is oversimplifying. Refusing means the state has no breath number. But the refusal suspension still hits your license, the refusal itself is admissible at trial, the state can still prosecute the DUI, and refusing disqualifies you from the one-time first-offense expungement under § 63-11-30(13). Every case is different, and no outcome is guaranteed either way.
Can I fight the refusal suspension?
Yes, but the window is short. After the Commissioner of Public Safety sustains the suspension, Miss. Code § 63-11-25 gives you 10 days to petition the circuit or county court for judicial review. The court hears the matter fresh, in a trial de novo without a jury. Be aware: you cannot drive while that appeal is pending.
Does refusing the test affect expungement later?
Yes, and this is the part most people never hear at the roadside. Mississippi's first-offense DUI expungement, § 63-11-30(13), is available only if you did not refuse the test, among other conditions. Refuse, and that one-time route to clearing the conviction is gone, even if you meet every other requirement five years later.
