Understanding DWI/DUI/OVI Detection and the Importance of SFST Training for Your Attorney

Understanding DWI, DUI, and OVI Charges

DWI, DUI, and OVI charges are serious legal matters. They can lead to severe penalties, including fines, license suspension, and even jail time. The consequences of these charges can linger long after the legal process concludes.

The DWI Detection Process

DWI detection starts with law enforcement officers watching drivers for signs of impairment. Commonly observed behaviors include weaving between lanes, sudden stops, or driving at inconsistent speeds. According to the NHTSA, about 28% of traffic fatalities in the United States are linked to impaired driving.

What are Standardized Field Sobriety Tests (SFST)?

Standardized Field Sobriety Tests (SFST) are a set of three assessments that officers use to gauge a driver's level of impairment:

  1. Horizontal Gaze Nystagmus (HGN): This test checks the eyes for involuntary jerking as they follow a moving object.
  2. Walk-and-Turn (WAT): The driver must walk heel-to-toe along a straight line, turn, and return to the start. Studies show that 68% of drivers with a BAC of 0.10% or higher fail this test.
  3. One-Leg Stand (OLS): The driver must stand on one leg while counting out loud.

Why Your Attorney Should Be Trained in SFST

When facing DWI charges, hiring an attorney who understands the details of SFSTs can greatly influence your case outcome:

  • Understanding the Science Behind SFSTs — An attorney knowledgeable in SFSTs can pinpoint potential flaws during the testing.
  • Identifying Officer Errors — A trained attorney can recognize mistakes during the tests, such as miscommunication or environmental factors.
  • Building a Strong Defense — A skilled attorney can develop effective defense strategies and argue that tests were improperly administered.
  • Negotiating Better Outcomes — If inconsistencies are found in the prosecution's evidence, it could lead to diminished charges or alternative sentencing.
