Here's how breath testing actually works in Arkansas, where the accuracy problems come from, and how an experienced defense attorney challenges a breath test result.
The Core Point
A breath test result is not self-proving. For the number to come into evidence, the State must show the machine was properly certified and maintained, the operator was properly certified, and the test was administered according to Arkansas Department of Health regulations. Each of those requirements is a place where cases are won.
There are two very different breath tests in a typical Arkansas DWI case, and the distinction matters:
| Test | When | Legal Status |
|---|---|---|
| Portable Breath Test (PBT) | Roadside, before arrest | Voluntary. Generally used only for probable cause — the number is typically not admissible at trial to prove BAC. |
| Evidentiary Breath Test | At the station, after arrest | Covered by implied consent. This is the number the State uses at trial. |
The evidentiary test in Arkansas is administered on an approved instrument — commonly the Intoxilyzer — under the oversight of the Arkansas Department of Health (ADH), which regulates breath testing statewide. ADH rules govern which instruments are approved, how they're calibrated and maintained, who may operate them, and how the test must be administered.
Breath machines don't measure blood alcohol directly. They measure alcohol in breath and use a conversion ratio to estimate blood alcohol. Every step of that process introduces potential error:
Calibration Drift
Machines drift out of calibration over time. If calibration checks were missed, late, or failed, the reading is suspect.
Mouth Alcohol
Burping, belching, acid reflux (GERD), vomiting, dentures, or recent drinking can put raw alcohol in the mouth — producing falsely high readings that don't reflect blood alcohol.
Rising BAC
Alcohol takes time to absorb. Your BAC at the station may be higher than it was when you were driving — and the State must prove your BAC at the wheel.
Partition Ratio Variability
Machines assume a standard breath-to-blood conversion ratio. Actual ratios vary between individuals and even within the same person over time.
Physiological Factors
Body temperature, breathing pattern, lung capacity, and certain medical conditions (diabetes, ketosis, GERD) can all skew results.
Radio Frequency & Environmental Interference
Electronic interference and environmental contaminants in the testing room can affect some instruments.
None of this means every breath test is wrong. It means a breath test number is an estimate produced under conditions that must be proven correct — not an unchallengeable fact.
For a breath test result to hold up in an Arkansas courtroom, the State generally needs to establish:
Every one of these is documented somewhere — machine logs, calibration records, certification cards, station video. A defense attorney's first move in a breath test case is requesting all of it.
Timing matters in Arkansas breath testing. When a test is administered promptly, the State benefits from a presumption connecting the result to the time of driving. When testing is significantly delayed — Arkansas case law has addressed tests administered more than two hours after the relevant driving — the connection between the number and your BAC at the wheel weakens considerably.
A delayed test opens the door to the rising BAC defense: if you drank shortly before driving, your BAC may have still been climbing when you were stopped — meaning the station reading could be higher than your BAC while actually driving. The State must prove your BAC at the time of driving, not at the time of testing. In borderline cases (0.08–0.10), this argument alone can create reasonable doubt.
Arkansas law gives a person who submits to the State's chemical test the right to obtain an additional independent test administered by a qualified person of their own choosing. Law enforcement is required to advise you of this right and provide reasonable assistance (such as access to a phone) in obtaining it.
This matters for two reasons. First, an independent blood test can directly contradict a flawed breath result. Second, if police failed to advise you of the right or obstructed your attempt to exercise it, that failure itself can become a defense issue. Few defendants know this right exists — which is exactly why it's worth asking about in every breath test case.
A breath test challenge is built from records, not speculation. The typical sequence:
1. Request the Machine's Records
Calibration logs, maintenance history, certification records, and any repair or error history for the specific instrument used — not just a blanket "the machine was certified" statement.
2. Verify the Operator's Certification
Was the officer's ADH operator certification current on the test date? Expired or lapsed certification is a direct admissibility problem.
3. Reconstruct the Observation Period
Station video, body-cam, and booking records often show the "continuous observation" wasn't continuous — the officer was filling out paperwork, the subject burped or belched, or the period was cut short.
4. Build the Timeline
Time of driving, time of stop, time of test. Delay supports rising BAC arguments; drinking history and food intake fill out the absorption picture.
5. Screen for Medical Factors
GERD, diabetes, dental work, recent illness — conditions that create mouth alcohol or skew readings get developed through medical records and, when warranted, expert testimony.
6. File the Right Motion
Depending on what the records show, the remedy may be a motion to suppress the result entirely, a motion in limine limiting how it's presented, or cross-examination that reduces the number's weight with the jury.
And remember — the breath test is only one layer of the case. The legality of the stop, the field sobriety tests, and the arrest itself all come first. If the stop or arrest was unlawful, the breath test result can fall with them regardless of how the machine performed.
Blood tests are generally more accurate than breath tests, but they have their own challenge points: chain-of-custody gaps, contamination or fermentation of the sample, lab procedures, and warrant issues. Under Birchfield v. North Dakota, police generally need a warrant (or valid consent) for a blood draw. A warrantless, nonconsensual blood draw is a serious constitutional problem for the State.
The breathalyzer number feels final to most people who get arrested. It isn't. It's an estimate, produced by a machine that requires proof of calibration, operated by a person who requires proof of certification, under procedures that require proof of compliance — connected to your driving by a timeline the State has to establish.
In borderline cases especially, a properly developed breath test challenge can be the difference between a conviction and a dismissal. The records that make these challenges possible need to be requested early — before they become harder to obtain. For the full picture of what happens after a DWI arrest, see our step-by-step first-offense DWI guide.
Failed a Breath Test in Arkansas?
A breath test number is challengeable — but only if the machine records, certification documents, and station video are requested before they're gone. And remember: you have just 7 days from arrest to request your license hearing.

]]>Here's what you need to know about your rights at an Arkansas DWI checkpoint, what makes a checkpoint legal, and how checkpoint cases get challenged.
The Key Point
A checkpoint stop is a seizure under the Fourth Amendment that happens without any individualized suspicion. Courts only allow it because of strict procedural safeguards. When the State can't prove those safeguards were followed, the evidence from the stop can be suppressed — and the case may collapse.
Yes — but conditionally. The U.S. Supreme Court upheld sobriety checkpoints in Michigan Department of State Police v. Sitz (1990), ruling that the public interest in combating drunk driving can justify brief, suspicionless stops if the checkpoint is properly conducted. The Eighth Circuit confirmed checkpoints are permissible in Arkansas under both the state and federal constitutions in Brouhard v. Lee (1997).
Importantly, Arkansas has no specific statute authorizing or governing DWI checkpoints. Instead, their legality is governed entirely by constitutional law and court precedent. That means the rules come from case law — and case law gives the defense specific, concrete requirements to test against.
Courts evaluate checkpoint legality using a balancing test that weighs three factors:
Beyond the general balancing test, the Arkansas Supreme Court has set specific requirements. The State must show that the checkpoint was carried out pursuant to a previously established, objective, and neutral plan designed by supervising officers — not by the officers in the field. The whole point is to remove individual officer discretion about who gets stopped.
Supervisory Authorization
The plan must be created by supervising officers in advance, not improvised by officers on the scene.
Neutral Stopping Criteria
Officers must follow a uniform, predetermined pattern (every car, every third car, etc.) — not stop drivers based on hunches.
Adequate Warning
Clear signage, lighting, and marked law enforcement presence so drivers know it's a legitimate police checkpoint.
Minimal Intrusion
Stops must be brief — a short interaction unless the officer develops reasonable suspicion to investigate further.
Safety Considerations
Location, time, and setup should reflect legitimate safety planning, not arbitrary selection.
Documentation
There must be an actual plan. It doesn't have to be written before the checkpoint, but the State must prove a genuine plan existed.
One nuance worth knowing: under Arkansas case law, the plan does not have to be written down in advance — it can be documented afterward — but there must genuinely have been a plan that constrained the field officers' discretion. The absence of any real plan is a significant vulnerability for the State.
If you're stopped at a checkpoint, you have both obligations and rights. Knowing the difference matters:
| You Must | You Can Decline |
|---|---|
| Stop when directed Roll down your window Provide license, registration, and insurance Comply with lawful orders | Field sobriety tests (voluntary) The roadside portable breath test (voluntary) Answering questions beyond basic identification Consenting to a vehicle search |
A few important clarifications:
This is one of the most common questions — and the answer is nuanced. You are generally allowed to lawfully avoid a checkpoint if you can do so legally (for example, turning onto a different route before reaching it). Avoiding a checkpoint is not itself illegal.
But how you avoid it matters. In Coffman v. State (1988), an Arkansas court found that an officer had reasonable suspicion to stop a driver who pulled into a driveway and drove off in the opposite direction specifically to evade a roadblock. The lesson: if avoiding the checkpoint requires an illegal maneuver (an illegal U-turn, crossing a median, a traffic violation) or looks like obvious evasive action, that conduct itself can give police a separate, lawful reason to stop you.
So while you have the right not to drive through a checkpoint, you can't commit a traffic violation to avoid one — and dramatic evasive maneuvers may create the very suspicion that justifies a stop.
Because checkpoints involve suspicionless stops, they're held to a high standard — and the burden is on the State to prove the checkpoint was constitutional. A defense attorney challenging a checkpoint case will typically request and scrutinize:
If the State can't prove the checkpoint met constitutional requirements, the evidence gathered — breath test results, observations, statements — may be suppressed. In a DWI case built primarily on the checkpoint stop, suppression frequently means dismissal.
DWI checkpoints are legal in Arkansas, but only when police follow the constitutional rules — a neutral plan, supervisory authorization, uniform stopping criteria, adequate warning, and minimal intrusion. Because the State bears the burden of proving the checkpoint was conducted lawfully, checkpoint cases often present strong opportunities for a motion to suppress.
If you were arrested at a sobriety checkpoint, the legality of that checkpoint should be examined closely — and early. For a complete walkthrough of what happens next, see our guide to the first-offense DWI process step by step.
Arrested at a DWI Checkpoint in Arkansas?
Checkpoint cases hinge on whether police followed strict constitutional rules — and the State has to prove they did. The sooner the checkpoint procedures are examined, the stronger the challenge. Remember: you have only 7 days to request your license hearing.

]]>A first-offense DWI in Arkansas isn't just a traffic ticket. It's a criminal charge with mandatory minimum jail time, a six-month license suspension, hard deadlines, and consequences that follow you for years. The decisions made in the first days after arrest often shape the outcome more than anything that happens later.
This guide walks through what actually happens — chronologically — from the moment a Little Rock or central Arkansas driver is pulled over through the resolution of the case and beyond.
7-Day License Hearing Deadline
If you've just been arrested for DWI, you have only 7 calendar days from the date of arrest to request an administrative hearing to challenge your license suspension. Miss this deadline and your right to fight the suspension is gone — automatically. Read the full 7-day rule guide here.
Most DWI cases start with a traffic stop — a swerve, a missed signal, an expired tag, or an alleged minor traffic violation. The officer needs reasonable suspicion to stop you and probable cause to arrest you.
Once stopped, the officer is gathering evidence:
If the officer believes there's probable cause to arrest, you'll be handcuffed and transported. The official chemical test (usually a breath test on the Intoxilyzer 8000 at the station) is governed by Arkansas's implied consent law (§ 5-65-202) — refusing it triggers automatic license suspension and can be used as evidence at trial. Read more about refusing the breath test here.
After arrest, you'll be transported to the local jail or detention center. Booking includes fingerprinting, photographing, an inventory of your possessions, and the official chemical test if you've agreed to it. Most first-offense DWI defendants are released within hours on bond — sometimes on a signature bond, sometimes after posting cash or surety. Read more about how bond works in Arkansas.
Before you leave the jail, the arresting officer will have:
That paperwork is the official starting point of two parallel processes — the criminal case and the administrative license suspension — that move on entirely separate tracks.
A DWI in Arkansas isn't one case — it's two:
| Track | What's at Stake | Decided By |
|---|---|---|
| Criminal Case | Jail, fines, criminal record, court-ordered programs | District or circuit court judge (or jury) |
| Administrative License Suspension | Driver's license suspension, ignition interlock requirements, hardship license | Arkansas Office of Driver Services |
The two cases proceed independently. You can win the criminal case and still lose your license, or vice versa. This is one of the reasons DWI defense is more complex than people expect — both fronts need attention.
Within 7 calendar days of arrest, you (or your attorney) must request an administrative hearing through the Arkansas Office of Driver Services. This hearing is the only opportunity to challenge the license suspension before it takes effect.
If you don't request the hearing in time:
Even if you intend to plead guilty in the criminal case, requesting the hearing matters. The administrative hearing creates an early opportunity to gather evidence and identify weaknesses in the State's case. Many DWI cases that seem hopeless develop usable defenses in the administrative process.
Your first court date is the arraignment. Here, the judge formally reads the charges and you enter a plea. Most defendants enter "not guilty" at this stage — not because they're disputing the facts, but because pleading guilty too early forfeits the chance to negotiate, develop defenses, or identify suppression issues.
The judge may also:
First-offense misdemeanor DWI cases are typically handled in district court (or city court, depending on jurisdiction). Felony DWIs (4th+ offense within 10 years) are handled in circuit court.
Between arraignment and resolution, the defense investigates the case. This is where most of the real work of DWI defense happens. Key activities include:
Discovery
Obtaining police reports, body-cam, dash-cam, breathalyzer maintenance records, and officer training records.
Stop Analysis
Was the stop legal? An unlawful stop can result in suppression of everything that followed.
FST Review
Body-cam comparison against the officer's report often reveals contradictions in field sobriety claims.
Breathalyzer Issues
Calibration logs, operator certification, observation period compliance, and machine maintenance records.
Motion to Suppress
If the stop, search, or arrest was unlawful — or if Miranda was violated — evidence can be suppressed.
Negotiation
Discussions with the prosecutor about resolution — though Arkansas prohibits "pleading down" DWI to lesser charges.
Pretrial timelines vary. Some cases resolve in 60-90 days; others take 6+ months, particularly in busier counties.
Most first-offense DWI cases end one of three ways:
If a suppression motion succeeds, the State's evidence may be insufficient to proceed. DWI cases can be dismissed for unlawful stop, unlawful arrest, breath-test problems, lab errors, or constitutional violations. Dismissal is the best possible outcome — no conviction, no penalties.
Important: Under § 5-65-107, Arkansas DWI cases cannot be plea-bargained down to a lesser offense like reckless driving. A plea in a DWI case is a plea to DWI — but the terms can still be negotiated (jail time vs. community service, fine amount, treatment requirements, etc.).
A small percentage of cases go to trial — either bench trial (judge decides) or jury trial. The State must prove DWI beyond a reasonable doubt. DWI cases can be defeated at trial with the right facts and preparation.
If you're convicted of a first-offense DWI under § 5-65-103, the statutory penalties include:
| Penalty | Range |
|---|---|
| Jail time | 1 day to 1 year (the hours after arrest typically count for a day) |
| Fine | $150 to $1,000 plus court costs (typically $300+) |
| License suspension | 6 months |
| Alcohol education | Mandatory completion of state-approved program |
| Victim Impact Panel | Mandatory attendance |
| Ignition Interlock Device (IID) | Available for hardship driving privileges; required for full license restoration in most cases |
Outcomes can worsen if the offense involved:
A first-offense DWI conviction has consequences that extend well past sentencing:
In a first-offense DWI case, the highest-leverage decisions are made in the first two weeks: requesting the license hearing in time, preserving evidence, getting an attorney involved before saying anything that hurts the case, and starting suppression analysis early.
By the time many defendants think about hiring a lawyer — often after the temporary permit expires or right before a court date — meaningful options have already been lost. Body-cam footage may have been overwritten, the 7-day deadline has passed, statements have been made on jail calls, and the State's narrative has hardened.
A first-offense DWI in Arkansas is defensible. But it's most defensible early.
Arrested for a First-Offense DWI in Arkansas?
You have only 7 days from arrest to request your administrative hearing. The decisions made in the first two weeks shape the entire case. Don't wait for your court date to think about defense.

]]>Arkansas runs two separate legal tracks after a DWI arrest: one in criminal court, and one through the Arkansas Department of Finance and Administration's Office of Driver Services. The administrative track moves fast. If you don't act within seven calendar days of your arrest, you may permanently lose your chance to challenge the suspension of your license.
Critical Deadline
Under Arkansas law, you have seven (7) calendar days from the date of notice to request an administrative hearing and contest your license suspension. Miss this window and the suspension becomes automatic — the hearing will not be granted after the deadline passes.
When an officer arrests you for DWI, the following happens in sequence:
Officer takes your physical license
At the time of arrest, the officer confiscates your driver's license and issues you an Official Driver's License Receipt.
You receive a Notice of Suspension (ALS Form)
This document officially notifies you that your license will be suspended. It also serves as your temporary driving permit for 30 days — but only if your underlying license was valid at the time of arrest.
7-day clock starts immediately
The ALS notice triggers your deadline. You have seven calendar days from the date of notice — not from your court date, not from when you hire an attorney — to request an administrative hearing with the Arkansas Office of Driver Services.
Day 30: Temporary permit expires
If no hearing is requested and no interlock restricted license is obtained, your ability to drive ends when the temporary permit expires.
One of the most important things to understand about a DWI case in Arkansas is that there are two completely independent proceedings happening at the same time. You can win one and lose the other.
| Criminal Court Track | Administrative Track |
|---|---|
| Handled in district or circuit court | Handled by Arkansas Office of Driver Services |
| Determines guilt, fines, and jail time | Determines your driving privileges only |
| Can take 6–12+ months to resolve | 7-day deadline to request a hearing |
| Outcome does not automatically protect your license | Moves independently of the criminal case |
Many people assume that if their criminal case goes well, their license will be fine. That is not how Arkansas law works. The administrative suspension proceeds on its own timeline regardless of what happens in court.
If no hearing is requested within seven days, the suspension takes effect automatically. The specific period depends on your situation:
| Situation | Suspension Period |
|---|---|
| First offense — failed or took breath test | 6 months |
| First offense — refused breath test | 180 days |
| Second refusal within 5 years | 2 years |
| Third refusal within 5 years | 3 years — no restricted permit available |
| Fourth refusal within 5 years | Lifetime revocation |
Once the deadline passes, a request for an administrative hearing will not be granted. (Ark. Code § 5-65-402; Arkansas DFA Office of Driver Services)
The administrative hearing is not a criminal trial. It is a focused proceeding with a limited scope — the hearing officer can only consider specific issues:
The burden of proof is on the State. Procedural errors by the arresting officer — an unlawful stop, failure to follow implied consent requirements, improper testing procedures — can be grounds to challenge the suspension.
Missing the seven-day deadline does not necessarily leave you without any recourse. Depending on your circumstances, you may still be able to request an interlock restricted license or a restricted driving permit:
These alternatives are not available in every situation — particularly if you refused chemical testing or have prior DWI offenses. The options available to you depend entirely on the facts of your case.
An attorney can simultaneously request the administrative hearing to protect your driving privileges and begin evaluating the criminal case. Waiting until you have a court date — which may be weeks away — almost certainly means the license deadline has already passed.
The seven-day deadline is the most time-sensitive issue in most DWI cases, and it is the one people most often miss. They are focused on the arrest, on work, on family — and by the time they start thinking about the license, the window has already closed.
By the time the criminal case is moving forward, the license issue may already be permanently decided against you.
If you were arrested for DWI in Arkansas, the clock is already running.
Act Before the Deadline Passes
A DWI arrest starts two legal processes simultaneously. An experienced attorney can protect your driving privileges and begin building your defense — but only if you act before the seven-day window closes.
