DPS Forensic Alcohol Testing Protocols is a AZ DPS's primary-source document. It documents the procedural and foundational requirements for evidentiary breath and blood testing in Arizona. Because it is the government's own source material, it sets the standard a DUI case can be measured against — not a standard the defense invented.
What this document establishes
It sets out the procedural and foundational requirements for evidentiary breath and blood testing in Arizona. As primary-source material, it lets you compare what actually happened in a case against the written standard, rather than relying on how the procedure is described in court.
How it's used in a DUI defense
Breath and blood results rest entirely on procedure: the continuous 15-minute observation/deprivation period, instrument calibration and maintenance logs, a qualified draw, a DPS-approved kit, the right preservative and anticoagulant, and an unbroken chain of custody. Any gap in that record is a recurring suppression theme, and the BD Vacutainer recall history is a documented challenge to tube integrity.
