What defenses work in Rhode Island underage DUI cases?

Defenses include breath test accuracy at low BACs (machine error margin can put you back under 0.02), mouth alcohol from mouthwash or breath spray, bad stop justification, procedural defects in the underage notification process, and challenges to roadside conditions during field tests. Young drivers' performance on FSTs is also disproportionately affected by anxiety and unfamiliarity.
