This exposes them to human error, bias, and external elements that are not directly related to the consumption of alcohol.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hypothetical Problems With Field Sobriety Test Evidence.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DUI lawyers typically object to the reliability of FSTs, stating that there are a number of weaknesses, including:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Medical Conditions &#8211;<\/strong> Balance and coordination may be impaired by inner ear problems, neurological problems, or injuries.<\/li>\n\n\n\n<li><strong>Environmental Factors<\/strong> &#8211; Results may be biased by uneven pavements, inappropriate lighting, or weather conditions.<\/li>\n\n\n\n<li><strong>Poor Instructions<\/strong> &#8211; When an officer does not explain the test, a driver is likely to commit errors that do not have any relation to intoxication.<\/li>\n\n\n\n<li><strong>Subjective Interpretation &#8211;<\/strong> The officers rate the performance based on their judgment, and this may be influenced by bias.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">These points leave room for the defense lawyers to present the fact that the results of the test should not be treated as good evidence of impairment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The defense of DUI Lawyers.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are various ways in which an experienced DUI attorney defends a client presented with evidence of field sobriety testing:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Cross-Examining the Officer<\/strong>&#8211; The lawyers ask numerous questions about how the test was administered and the procedure used, and whether any outside factors were considered.<\/li>\n\n\n\n<li><strong>Adding Expert Testimony<\/strong> &#8211; Medical or scientific experts can also give evidence concerning conditions that might have caused poor performance other than alcohol.<\/li>\n\n\n\n<li><strong>Questioning the Credibility of the Test<\/strong> -Attorneys may argue that FSTs are not scientifically valid markers of impairment by citing studies and guidelines.<\/li>\n\n\n\n<li><strong>Emphasizing the Lapses of the video recordings<\/strong> &#8211; In case a video footage reveals that there are differences between what the officer wrote down and what actually happened, the defense can utilize that to make the prosecution weak.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Importance of Legal Representation.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Evidence of sobriety tests in the field is very influential in a DUI case, but it is not infallible. In the absence of an effective legal defense, one can easily be penalized by being suspended, fined, and even sent to jail. A qualified DUI attorney is aware of the intricacies of the tests and can readily fault their validity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Final Thoughts<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When one is charged with DUI on the basis of the results of field sobriety tests, it does not necessarily imply that he or she is guilty. These are subjective tests that are defective and not reliable. Through the assistance of a skilled DUI attorney, a defendant has an opportunity to argue the case, defend their rights, and achieve the most favorable result in court.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the case of any individual who is charged with DUI, an educated legal counsel is the best strategy to ensure that the questionable evidence of field sobriety tests does not undermine the defendant&#8217;s case.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A field sobriety test (FST) is one of the first actions that a law enforcement officer can take when a person is suspected of drunk driving.
