Breath Alcohol Tests

Breath Alcohol tests are usually performed using a breathalyzer.  There are a number of different breathalyzers on the market and different versions are used with different arresting agencies.  Each generally operate the same.  You are required to submit to a chemical blood or breath test, however you are not required to submit to a PAS test or Preliminary Alcohol Screening which is done prior to arrest and used as a final field sobriety test to assist the officer in determining whether to place you under arrest for a San Jose DUI.  Breath Alcohol tests are somewhat unreliable due to human error or poor maintenance.  Breathalyzers must be maintained and calibrated according to a rigorous schedule and failure to show accurate records can result in an invalidation of the results.  If you or someone you know submitted to a Breath Test following an arrest for a San Jose DUI contact our firm now by filling out our free online case evaluation.
