NHTSA Extra Eyes Report is a NHTSA's research report in the government's underlying science library. It documents the underlying science on alcohol, drugs, driving performance, and detection methods. 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 underlying science on alcohol, drugs, driving performance, and detection methods. 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
The broader research library frames the science for the fact-finder — how weak individual driving cues actually are, how impairment correlates (and doesn't) with a given BAC, and where roadblock and detection methods fall short. It is the primary-source counterweight to the courtroom shorthand that treats every cue and every reading as conclusive.
