Why These Manuals Matter
The NHTSA Standardized Field Sobriety Testing manuals are the playbook every Arizona officer is trained from — and the standard every officer is judged against at trial. If the officer deviated from the manual on the Horizontal Gaze Nystagmus, the Walk-and-Turn, or the One-Leg Stand, the results should not come into evidence. We keep the full library here, free, for defense attorneys, law students, and self-represented defendants who need to prepare.

Every manual in this library has been cited in a motion to suppress or a cross-examination in Arizona DUI courts. The NHTSA SFST Full Manual is the foundation for every HGN challenge. The DEC manual is the baseline for every drug DUI cross. The Arizona DPS Breath SOP is the foundation for every Intoxilyzer challenge. Knowing the source material cold is the difference between a dismissal and a conviction.
