There are two forms of Chemical evidence for a WI DUI, a blood test or a breath test.  A Wisconsin DUI breath test is taken with a machine known as EC/IR II.  The EC/IR II machine takes two breath sample readings to determine a person’s Blood Alcohol Content (BAC).  The training of the officer administering the test, the results of the test, and the maintenance of the EC/IR II machine are important factors taken into consideration by WI DUI Defense Attorney Nathan J. Dineen when defending against a WI DUI.

Attacking wi dui breath test results

Wisconsin DUI Breath Test Equipment should be regularly maintained.  There should be careful calibrations to the EC/IR II machine in order to determine accurate and reliable results.  An experienced DUI Defense Attorney will check the records of the machine used for each case.  If the records of the equipment are too perfect or have too many flaws, the results of the machine may be faulty.

Wisconsin breath test errors

Wisconsin police officers must be trained to administer the EC/IR II breath test, so it would only make sense that an attorney Fighting your WI DUI is also trained.  These machines will have errors.  Everything must be analyzed to determine the validity of the results.  There can be cases of excess Mouth Alcohol or peaking BAC.
