Preliminary Alcohol Screening (PAS) Test: DUI Arrest In Orange County



A Preliminary Alcohol Screening (PAS) machine is portable, handheld breath test device The preliminary alcohol screening test is not supposed to be determinative” of your blood-alcohol content but is a “field sobriety test” which may be used as a further investigative tool in order to establish reasonable cause to believe a person was driving a vehicle while under the influence of alcohol. DUI Lawyers in Orange County routinely challenge the validity of the results for these breath-testing devices, which must be used, calibrated and maintained in accordance with the guidelines of Title 17.
It is now fairly routine for law enforcement in Orange County to use the PAS during a DUI investigation. This test is voluntary and the law specifically requires the DUI officer to tell you that you don’t have to take the test. Your refusal to take the PAS test during a DUI investigation cannot be used against you in court. In my experience a majority of police and CHP officers in Orange County do tell people that they may refuse the PAS, but a good number of officers make it a policy not to admonish the subject of a DUI investigation that he or she may refuse the test. Unfortunately, even if a DUI investigator does not comply with their legal duty to tell people that the test if voluntary, the result is still admissible in court. The only consequence is that your Orange County DUI Attorney will tell the jury that the officer was supposed to tell the person on trial for a DUI of the voluntary nature of the test but didn’t do it.
The most commonly used PAS device in California is the Alco-Sensor IV, which is capable of being downloaded, making the computer printout of all information processed through the unit. Some models are also capable of having a printed breath ticket processed at the time the test is given. As with any other breath machine, the PJAS doesn’t save any breath sample.

If the DUI officer does not use the PAS correctly, or if the PAS device was not properly calibrated or maintained, your DUI defense lawyer will make an Evidence Code Section 402 motion just before trial starts. In order to justify admitting the PAS evidence the District Attorney (DA) must either 1) show that the law enforcement agency responsible for the PAS has complied with the regulations set out in Title 17 of the California Code of Regulations for the maintenance of the PAS equipment and the training of personnel administering the test; or 2) Provide independent proof that the PAS test met three foundational requirements of People v. Adams (1976) 59 Cal.App.3d 559—That the PAS machine was in proper working order; That the test used was properly administered; and The operator was competent and qualified.
