Arizona DUI Information

Many people mistakenly believe that there is no way to fight DUI charges when a blood or breath test shows that they are above the legal limit or a police officer testifies that they appeared intoxicated and failed various field sobriety tests.  However, DUI investigations are often done improperly and the science behind all of these tests is far from infallible.  There are many ways to challenge blood or breath test results.  Blood samples are often taken by police officers at the scene under less than ideal conditions.  They are then tested by overburdened crime labs that do not always use or adhere to ideal protocols.  Expert review of these blood tests often reveals errors or the presence of contaminants that call the results into question.

Breath tests are generally less accurate than blood tests.  Many times they are conducted improperly.  Moreover, breath test results can be affected by a variety of factors and can show a person’s blood alcohol concentration (“BAC”) to be much higher than it actually is.

There are also many issues with the “science” behind field sobriety tests.  There are usually even more issues with the way police officers administer these tests in the field.  It is important that you consult an experienced DUI lawyer who understands the science behind DUI investigations and the issues that can arise.  This can substantially increase your chance of attaining a favorable outcome in your DUI case.  Call us for a free case assessment at (520) 314-4125 or contact us online.
