Common DUI defense strategies in Las Vegas include challenging the legality of a traffic stop, questioning field sobriety tests, disputing breath or blood test results, and examining police observations for inconsistencies. Under Nevada law, the prosecution must prove the elements of a DUI offense beyond a reasonable doubt. Depending on the evidence, a defense attorney may be able to challenge the charges or seek dismissal.
1. Challenging the Legality of the Traffic Stop
Police generally need reasonable suspicion of a traffic violation or criminal activity to pull someone over.
If an officer stops a driver without sufficient legal justification, evidence obtained during the stop may be challenged.
A DUI defense attorney can review police reports, dashcam footage, and the circumstances leading to the stop. If the stop violated the driver's constitutional rights, certain evidence may be excluded from court.
2. Questioning Field Sobriety Test Results
Field sobriety tests are commonly used during DUI investigations, but their results aren't always reliable.
Several factors can affect performance, including:
Medical conditions or physical disabilities
Uneven surfaces or poor lighting
Fatigue, nervousness, or anxiety
Improper instructions or test administration
An attorney may challenge whether the officer conducted the tests correctly and whether the results accurately indicate impairment.
3. Disputing Breathalyzer and Blood Test Results
Under Nevada Revised Statutes (NRS) 484C.110, a blood alcohol concentration (BAC) of 0.08% or higher can support a DUI charge. Drivers may also face charges below that limit if they are impaired.
Chemical test results may be challenged when there are concerns about:
Improper breathalyzer calibration or maintenance
Errors in testing procedures
Blood sample contamination or improper storage
Incomplete chain-of-custody documentation
A defense attorney may examine testing records to identify errors that could affect the reliability or admissibility of the evidence.
4. Challenging the Officer's Observations
Police officers often rely on observations such as bloodshot eyes, slurred speech, or unsteady movement when investigating suspected DUI offenses.
These symptoms don't always indicate intoxication.
Fatigue, allergies, anxiety, or medical conditions can sometimes produce similar signs.
Bodycam footage, witness testimony, and other evidence may help determine whether an officer's observations accurately reflect what happened.
5. Presenting Alternative Explanations for Impairment
Certain medical conditions, including neurological disorders and conditions affecting blood sugar or balance, can cause symptoms that resemble intoxication.
Medical documentation or expert testimony may help explain these symptoms and challenge assumptions about impairment.
It's important to understand that having a valid prescription does not automatically protect someone from DUI charges in Nevada. Driving while impaired by certain prescription medications can still violate state law.
Can DUI Charges Be Dismissed in Las Vegas?
Yes, DUI charges can sometimes be dismissed when the evidence is insufficient, key evidence is excluded, or the prosecution cannot establish the required elements of the offense.
Nevada law restricts when prosecutors can dismiss DUI charges or reduce them through plea agreements. Under NRS 484C.420, dismissal may be permitted when the charge lacks probable cause or cannot be proven at trial. The available defense options depend on the specific circumstances of the case.

Frequently Asked Questions About DUI Defense in Las Vegas
Can you fight a DUI charge if your BAC was over 0.08%?
Yes. Even when a chemical test shows a BAC of 0.08% or higher, the defense may challenge testing accuracy, procedures, or the admissibility of evidence.
Can you be charged with DUI in Nevada if your BAC is below 0.08%?
Yes. Nevada law allows DUI charges when a driver is impaired by alcohol or certain drugs, even without a BAC at or above 0.08%.
Can an illegal traffic stop lead to DUI charges being dismissed?
Potentially. If a court finds the stop unconstitutional, certain evidence may be suppressed. Dismissal may be possible if the remaining evidence is insufficient.
Can medical conditions affect field sobriety test results?
Yes. Medical conditions affecting balance, coordination, speech, or eye movement may influence performance and provide grounds for challenging test results.
Can you challenge a DUI blood test in Nevada?
Yes. Blood test results may be challenged based on improper collection, storage, laboratory procedures, or chain-of-custody concerns.
