There are varying types of field sobriety tests that can establish cause for a DUI arrest. Law enforcement officers do not always administer these tests accurately, however, so a South King County DUI defense attorney may examine the results of a client’s field sobriety tests in order to discover whether they are correct and can be used in court.
What Types of Field Sobriety Tests Can Law Enforcement Officers Conduct?
- Coordination tests
- Horizontal gaze nystagmus test
A South King County DUI defense lawyer regularly investigates field sobriety tests because those that are administered incorrectly cannot generally prove a defendant’s inebriation.
How Can a South King County DUI Defense Attorney Analyze Coordination Tests?
A South King County DUI defense attorney will probably ask questions geared toward evaluating a client’s coordination skills on a normal day. If a client is naturally uncoordinated, this may skew evaluation results.
The South King County DUI defense lawyer may also ask about the environment or setting of the evaluations.
- If the defendant was required to walk a straight line and pivot, was the ground even or sloped?
- Was the environment brightly lit or dark?
In addition, a South King County DUI defense attorney will most likely determine whether the defendant can perform coordination tests while sober. If he or she cannot, the defendant will likely have to prove this in court to demonstrate that a law enforcement officer may have incorrectly interpreted field sobriety test results.
How Will a South King County DUI Defense Attorney Determine Whether the Horizontal Gaze Nystagmus Test Was Accurately Administered?
The horizontal gaze nystagmus test enables police officers to observe jerky eye movements that may indicate alcohol influence. A South King County DUI defense lawyer frequently does two things to evaluate test results:
- Review videotape of the test to conclude whether the test was properly or improperly conducted.
- Test clients for naturally occurring nystagmus to evaluate the role this may have had in field sobriety test results.
