Driving under the influence (DUI) charges are often quite complex and involve many outside tests, regulations, and requirements. Arizona law has several harsh penalties put into place to try and curb the existence of DUI offenses which serve not only to aggravate existing charges, but may also confuse the accused defendant. Field sobriety testing in Arizona is part of the tests, which go into a determination of whether you are driving under the influence at the time of arrest. However, these tests can often be unpredictable and inaccurate, leading to DUI charges that have the potential to remain on your record. If you are facing DUI charges stemming from field sobriety testing in Arizona, do not hesitate to contact an experienced Phoenix field sobriety test defense lawyer.
Field sobriety tests are different from blood tests and breathalyzers, which can accurately record your BAC at the time of your arrest or shortly thereafter. Field sobriety tests are performed by law enforcement officers on suspected DUI defendants and are supposed to focus on the human capabilities necessary to safety drive. The tests these law enforcement officers use are based on the National Highway Traffic Safety Administration (NHTSA), which in turn are based on scientific studies. However, these studies are not conducted by the NHTSA but instead are conducted by people who receive grant money for their work and none of these studies are in fact peer reviewed which involves critique of the method by other experts in the field. As a result, field sobriety tests are based on overarching national standards which have not been carefully reviewed by anyone without a monetary interest in mind.
One of the most basic field sobriety tests includes the basic “Walk and Turn” test, which requires a suspected DUI defendant to walk a straight line, heel to toe, then turn around and walk back. Law enforcement officers in Arizona use an imaginary line rather than a true line to perform the test and often point to the NHTSA handbook as proof that they can do this. However, the language is ambiguous in determining whether a real or imaginary line can be used, and to base a DUI charge off of an imaginary line “walk and turn” test offers plenty of room for error which DUI defense lawyers in Phoenix can use to their advantage.
Law enforcement officers continue to maintain that field sobriety tests indicate impairment. However, the amount of criticism that has emerged as the result of the lack of peer review on NHTSA guidelines as well as research that is not founded on much of anything has led many states to change their own jurisdictional laws.
DUI charges involve many different outside events and circumstances which add to your offense and often aggravate your existing charge. Field sobriety tests are one indication of the national discrepancy in DUI charges which date back to the 1970s during which the NHTSA was paid to perform research to develop tools to test for impairment.
