What Are Common Defenses to DUI Charges in Virginia?

 Posted on May 28, 2026 in DUI

If you have a Virginia DUI charge, that is just the start of your case, and not a predetermined final outcome.  You have the chance to challenge the state’s case against you, and having experienced legal assistance in making that challenge gives you the best chance for a better outcome on your record. There are strong, meaningful defenses available in DUI cases in Virginia, and depending on the facts, your charges may be reduced or dismissed. The evidence in a DUI case can often be challenged, and the prosecution has to prove its case beyond a reasonable doubt. If you are facing a DUI charge in 2026, Bret Lee, a Northern Virginia and Prince William County DUI defense lawyer can review what happened during your stop and help you build a strong, evidence-backed defense.

What Does Virginia Law Say About DUI?

Under Virginia Code § 18.2-266, it is illegal to drive while your blood alcohol content is at or above 0.08 percent, or while you are under the influence of alcohol to a degree that impairs your ability to drive safely.   There are also ways to be charged if the police believe you were under the influence of other drugs. The prosecution has to prove intoxication beyond a reasonable doubt. That standard allows for a strong defense, and there are several ways to challenge the evidence the state relies on.

What Are the Most Common Defenses to a DUI Charge in Virginia?

No two DUI cases are exactly the same, but certain defenses come up regularly and can be very effective when the facts support them. At Bret Lee Legal Solutions, we look at every part of your case to find where the state's evidence is weakest.  Sometimes that is the scientific evidence they want to introduce that has a critical flaw.  Other times it is about violation of your rights or required procedures in the investigation.

The Traffic Stop Was Not Lawful

Before an officer can legally stop your vehicle, they must have reasonable suspicion that a law has been violated. If the stop was not supported by reasonable suspicion, everything that followed, including field sobriety tests and chemical test results, may be subject to suppression under the Fourth Amendment. If the evidence is suppressed, the prosecution's case can fall apart entirely. A defense attorney like Bret Lee is equipped to challenge whether the prosecution is relying on illegally obtained evidence.

The Field Sobriety Tests Were Not Given Correctly

Field sobriety tests must be given in a specific way under precise conditions to produce reliable results. If the officer did not follow proper procedures, if the test was poorly explained or demonstrated, or in circumstances where it is unfair, such as being done on uneven ground, if the lighting was poor, or if a physical condition affected your performance, the results may not be reliable. Bret Lee will look closely at how the tests were given and whether any of these flaws apply to your case.

The Breath Test Result Was Not Reliable

Breathalyzer devices have to be properly maintained, regularly calibrated, and operated correctly to produce accurate readings. Under Virginia Code § 18.2-268.9, Virginia law sets requirements for the admissibility and handling of breath test evidence in DUI cases. If the device was not properly maintained, if required procedures were not followed, or if the test was otherwise unreliable, the breath test result may be challenged and excluded in court.

The Blood Test Was Not Handled Correctly

Blood tests can also be challenged. Under Virginia Code § 18.2-268.7, blood samples used in DUI cases are subject to specific procedures related to testing and handling. The sample must be properly stored and tracked through a documented chain of custody from collection through testing. If mistakes were made during any part of that process, the reliability of the result may be questioned or kept out of evidence entirely.

A Medical Condition Affected the Results

Certain medical conditions can cause elevated readings on a breathalyzer or affect blood test results in ways that have nothing to do with alcohol. Conditions like acid reflux, diabetes, and certain diets or medications can influence breathalyzer readings. If you have a condition that may have influenced the results, that is an important part of your defense.

The Evidence of Impairment Is Weak

Having something to drink before driving does not automatically mean you were impaired to the point where your ability to drive was affected. If your driving was not impaired and the overall evidence of impairment is weak, that argument can be a critical part of your defense before a judge or jury. Trust your defense attorney, like Bret Lee, to make sure your rights are upheld and your whole case is properly presented.

What Are the Consequences of a DUI Conviction in Virginia?

Understanding what is at stake makes it clear why fighting a DUI charge matters so much. A first offense DUI conviction in Virginia is a Class 1 misdemeanor. It carries a fine of at least $250, a mandatory license suspension of one year, and potential jail time. A second offense within ten years carries mandatory minimum jail time. A third offense within ten years is a felony. Beyond the criminal penalties, a DUI conviction can affect your insurance rates, your professional licenses, and your employment.
