Breath Testing in Idaho

Breath Testing in Idaho: Devices, Records, and Where Mistakes Happen

Idaho's breath program is run by Idaho State Police Forensic Services (ISPFS). Understanding how instruments are certified, maintained, and operated is central to your defense.

Breath Testing in Idaho Devices, Records, and Where Mistakes Happen

The program at a glance

  • ISPFS trains Breath Testing Specialists and operators, certifies instruments, maintains analytical methods, and publishes standard operating procedures.

  • Evidentiary instruments: Idaho deploys devices such as the Draeger Alcotest 9510 (and has legacy Intox 5000 histories).

  • Screening devices: Officers may also use portable breath testers (e.g., Lifeloc FC20) as preliminary tools.

Records we pull—every time

  • Operator certification & permit status (is the operator current?).

  • Instrument performance verification logs, maintenance entries, gas lot certificates, and uncertainty memos.

  • SOP compliance: We compare what actually happened to the state's own written methods (deprivation periods, mouth alcohol checks, control tests, duplicate agreement, etc.).

Common fault lines

  • Mouth alcohol & GERD: Residual alcohol elevates readings—procedure exists to guard against it.

  • Timing & temperature controls: Missed checks or expired standards undermine reliability.

  • Operator errors: Incomplete observation, bad sequencing, or skipping control tests.

  • Data integrity: Missing or inconsistent performance records.

What this means for your case

A “number” is not the end of the story. We use the program's own documentation to test whether the state met its burden—method, machine, and human.
