Alabama DUI Dismissal: Essential Motion Strategies

Strategic Defense Against DUI/DWI Charges

A charge of Driving Under the Influence (DUI/DWI) in Alabama carries severe penalties, including potential jail time, hefty fines, and mandatory license suspension. However, a charge is not a conviction. The most powerful tool in a defense strategy is often a well-crafted Motion to Dismiss or a Motion to Suppress Evidence, which challenges the fundamental legality and evidence of the State’s case. By meticulously scrutinizing police procedure and scientific evidence, a Legal Expert can expose fatal flaws that may lead to the entire case being thrown out.

I. The Fourth Amendment Challenge: Unlawful Traffic Stop

One of the earliest and most effective lines of defense involves challenging the legality of the initial stop, a violation of the Fourth Amendment. Law enforcement must have “reasonable suspicion” to pull a vehicle over for a suspected traffic violation or “probable cause” to detain the driver.

Key Ground for Motion to Suppress: Lack of Reasonable Suspicion

If a Legal Expert can demonstrate that the officer lacked a valid, articulable reason to initiate the traffic stop, all evidence collected thereafter—including Field Sobriety Test (FST) results, Breathalyzer readings, and officer observations—may be deemed inadmissible in court. The suppression of key evidence can cripple the prosecution’s ability to prove guilt beyond a reasonable doubt, often resulting in a dismissal of the DUI charge.

II. Attacking the Accuracy of Chemical Testing (BAC)

Alabama law establishes a per se intoxication limit of 0.08% Blood Alcohol Concentration (BAC). Challenging the accuracy of the breath or blood test is a primary defense strategy, as these machines and procedures are subject to human and mechanical error.

Grounds for Challenging BAC Evidence
Defense Strategy	The Flaw to Exploit
Improper Calibration/Maintenance	The state must prove the device was properly maintained and calibrated; lack of maintenance logs or a known margin of error can be grounds for suppression.
Uncertified Operator/Procedural Errors	The test must be administered by a currently certified operator who followed all state-mandated protocols. Failure to follow rules can render the test invalid.
Rising Blood Alcohol Defense	Using a process called retrograde extrapolation, a Legal Expert can argue the defendant’s BAC was below the legal limit while driving, but rose above it during the absorption phase by the time the test was administered.
Medical Conditions/Contamination	Conditions like GERD or diabetes can create “mouth alcohol,” leading to a falsely elevated breathalyzer reading. Contaminated blood samples (e.g., alcohol-laden swab) can also void the test.

💡 Legal Expert Tip: Scrutinizing the Evidence Chain

For blood or urine samples, the chain of custody is a critical point of attack. Any break in the documented control of the sample—from collection to lab analysis—can be used to argue that the evidence’s integrity has been compromised, making it susceptible to suppression.

III. Disputing Field Sobriety Test (FST) Reliability

Field Sobriety Tests (FSTs), such as the Walk-and-Turn or One-Leg Stand, are subjective tools used by officers to assess impairment. A motion to exclude these results can be based on several factors, asserting they are unreliable evidence of intoxication.

Improper Administration: Officers must follow strict, standardized protocols. If the officer failed to follow the proper procedure, the test results may be deemed unreliable.
Environmental Factors: Uneven surfaces, poor lighting, or adverse weather conditions can affect a driver’s balance and coordination, skewing the test results regardless of sobriety.
Physical/Medical Conditions: Pre-existing conditions (e.g., inner ear issues, bad knees, back problems), injury, or even wearing certain footwear can impact performance and be mistakenly interpreted as signs of impairment.

IV. Constitutional and Procedural Grounds for Dismissal

Motions to Dismiss can be filed when the case suffers from procedural defects or constitutional violations that prevent a fair trial.

Constitutional and Procedural Defects

Violation of the Right to a Speedy Trial: If there have been unreasonable, unexcused delays in bringing the case to trial, a motion to dismiss can be filed based on the Sixth Amendment right.
Double Jeopardy: The Fifth Amendment prohibits prosecuting an individual for the same offense twice. If this occurs, a motion to dismiss is appropriate.
Errors in the Charging Document: If the initial complaint or charging document was filed incorrectly and the error cannot be fixed, it may lead to a dismissal.
Miranda Rights Violations: While not a direct dismissal for the DUI charge itself, failure to read a defendant their rights before custodial interrogation can result in the suppression of any incriminating statements made to the police.

V. The “Actual Physical Control” Defense

Alabama law is unique in that a person can be charged with DUI not only for driving but also for being in “actual physical control” of a vehicle while intoxicated. This element is a separate legal hurdle the prosecution must clear.

Case Review: Challenging APC

A Legal Expert will analyze factors a jury uses to determine “actual physical control”. These include: where the intoxicated person was in relation to the car, the car’s location, where the keys were, and whether the engine was running. For example, if a driver was asleep in the backseat with the keys in their pocket and the vehicle off the road, the defense would argue they lacked the immediate ability to operate the vehicle, thus defeating one of the core elements of the crime.

Summary: Your Path to Potential Dismissal

A DUI/DWI case hinges entirely on the State’s evidence. The process of filing motions is your Legal Expert’s opportunity to challenge that evidence and procedure at every turn. A successful motion often removes the strongest evidence, making a conviction impossible and leading to a dismissal.

The most powerful dismissal strategy is the suppression of evidence stemming from a Fourth Amendment violation, such as an illegal traffic stop without reasonable suspicion.
Challenging BAC results based on equipment malfunction, lack of proper maintenance, or the officer’s lack of certification is essential to dispute the core of per se intoxication.
Procedural flaws, including violations of the right to a speedy trial or double jeopardy, can serve as standalone grounds for a Motion to Dismiss the entire case.
The defense of “Actual Physical Control” is unique to Alabama and can be a successful path to acquittal if the individual was merely occupying, but not controlling, the vehicle.

Post-Arrest Action Card

If you have been charged with a DUI/DWI, immediate and strategic action is critical. Your ability to contest a license suspension is often limited to a 10-day window following the arrest. Contact a Legal Expert immediately to preserve your rights, begin an investigation into potential procedural errors, and prepare the necessary motions to suppress or dismiss the charges.

Frequently Asked Questions (FAQ)

Can a DUI charge truly be dismissed in Alabama?

Yes. While not common, a full dismissal is possible when a significant legal or procedural flaw is discovered in the prosecution’s case, such as illegally obtained evidence, flawed testing procedures, or lack of probable cause for the initial stop.

What does “Motion to Suppress” mean in a DUI case?

A Motion to Suppress is a legal request to the court to exclude certain pieces of evidence from the trial. If crucial evidence, such as BAC test results or officer observations, is suppressed because it was obtained illegally or unreliably, the prosecution may be left with insufficient evidence to proceed, which often leads to dismissal.

How does a “Rising BAC” defense work?

This sophisticated defense argues that the driver’s blood alcohol level was still rising when the test was administered. The argument is that while the BAC may have been over the legal limit when the test was taken, it was below the legal limit at the time the individual was actually driving.

Is it better to refuse a breathalyzer test in Alabama?

Alabama has an Implied Consent law, meaning that by driving, you consent to chemical testing if suspected of DUI. Refusing the test will lead to an automatic, mandatory license suspension for at least 90 days, regardless of the outcome of the criminal case. While refusal may prevent the state from having a numerical BAC reading, the administrative penalties are immediate.

How long does a DUI conviction stay on my record?

In Alabama, a DUI conviction remains on your criminal record indefinitely. It will affect your driving record and insurance rates for a period of five years.
