A driving under the influence (DUI) stop can leave you replaying small details: whether the pavement was level, whether the officer explained each instruction, or whether fatigue affected your balance. These details can matter because field sobriety tests in Charlottesville DUI cases are based on an officer’s observations rather than a machine-generated number. A charge does not mean every roadside conclusion is beyond review.

A skilled DUI defense attorney at La Fratta Law can examine your stop, video footage, police reports, testing conditions, and breath or blood evidence to protect your rights. Our team can help evaluate whether traffic violations, reckless driving allegations, or driving under the influence charges were supported by proper procedures and evidence. Legal representation can provide a clearer assessment than self-representation, particularly where technical testing procedures and probable-cause questions overlap. Seeking advice early can also reduce uncertainty about court dates, license issues, and which records should be saved. To begin building your defense, contact our firm today.

What Do Field Sobriety Tests Measure?

The National Highway Traffic Safety Administration recognizes three standardized exercises to test driver sobriety. These include the horizontal gaze nystagmus, the walk-and-turn, and the one-leg stand. Officers use these tests to look for specific clues associated with impairment. The exercises do not directly measure blood alcohol concentration, and performance can be affected by the setting or your physical condition. These exercises are investigative tools, not scientific pass-or-fail tests. Their value depends on how they were instructed, demonstrated, performed, recorded, and interpreted in the circumstances.

A Charlottesville lawyer reviewing DUI roadside testing can consider whether the officer gave proper instructions, demonstrated the exercise, and scored only recognized clues. Other relevant details can include:

  • Uneven or sloped pavement
  • Poor lighting or passing traffic
  • Unsuitable footwear
  • Injuries or balance limitations
  • Confusing or interrupted instructions

Body-camera or cruiser video can be especially useful because it allows the defense to compare the officer’s report with what occurred. Meaningful inconsistencies may affect the weight given to the officer’s interpretation, but no single discrepancy guarantees suppression or dismissal. The review should also consider wind, visibility, age, injuries, balance limitations, footwear, and any medical concern disclosed to the officer.

How Does State Law Treat the Results?

The Code of Virginia § 18.2-266 prohibits driving with a blood alcohol concentration of 0.08 percent or higher and also prohibits operating a vehicle while under the influence of alcohol or drugs. Because the statute allows an impairment-based case without a qualifying chemical result, roadside observations can become part of the prosecution’s proof.

The rules for field testing evidence in Charlottesville DUI cases are different from the rules governing breath samples. Under Code of Virginia § 18.2-267, a driver can refuse a preliminary roadside breath analysis, and that refusal cannot be used as evidence in the driving under the influence prosecution. By contrast, Code of Virginia § 18.2-268.2 addresses implied consent to post-arrest chemical testing within three hours of the alleged offense.

An attorney can separate these stages and evaluate whether the officer had a lawful basis for the stop, reasonable suspicion to continue the detention, and probable cause to arrest. They can also examine whether medical conditions, weather, road design, or officer technique offer a reasonable explanation for the reported clues.

Discuss DUI Field Testing With A Charlottesville Attorney

If you are facing a charge involving field sobriety tests in Charlottesville DUI cases, an early review can preserve useful evidence and help you understand what the Commonwealth must prove. Michael La Fratta can compare the officer’s report with body-camera footage, examine the instructions and testing conditions, and determine how the roadside observations fit with the rest of the evidence. Medical limitations, footwear, weather, lighting, traffic, and the officer’s administration of the exercises may all matter. Contact our team at La Fratta Law early so relevant video and records can be identified and preserved.
