Is it possible to fight a blood or breath test in a DUI case?

A Tennessee DUI lawyer should never take a chemical or breath test at face value.  Different testing procedures are used across Tennessee to determine the amount of alcohol in a driver’s blood.  Some Tennessee law enforcement agencies choose to draw blood from a DUI suspect, others use a breath test, and some even obtain a urine sample for analysis.

No matter what testing mechanism is used, the tests are not foolproof.  Machines malfunction.  Like a toaster, dishwasher, or hair dryer, machines wear down and break over time. Devices that collect and analyze blood, breath and urine are no different.  Some machines and methods are less reliable than others.  The tests are further subject to error by those persons involved in the collection and analysis processes.

A Tennessee DUI attorney should be familiar with the different tests and machines used in Tennessee.  Hiring a motivated Criminal Defense lawyer gives someone the opportunity to fight all of the facts.  In some cases, it may be possible to prevent the chemical test result from being used as evidence.
