Califronia DUI Defense Attorney - EPAS Testing

An EPAS breath testing deviceis a hybrid machine that may be used to administer the Preliminary Alcohol Screening test usually given at the scene of the stop and the chemical breath test traditionally done at the station after arrest.  California DUI laws require chemical breath testing following an arrest for driving under the influence, however you are not required to take a breath test prior to being arrested unless you are under the age of 21.  The technology of the EPAS (Evidentiary Preliminary Alcohol Screening) device makes police agency work more concise.  They can use one machine for both the voluntary preliminary test and the mandatory chemical breath test.

It is important to remember that if you are arrested for a California DUI and refuse a chemical test you could face enhanced penalties such as a longer license suspension, required installation of an ignition interlock device or jail time.
