HB 2439 establishes new rules for law enforcement use of oral-fluid testing in DUI cases. It requires officers to use only approved devices, document specific driving-related reasons for testing (not general suspicion), and complete quality checks before each use. The bill mandates that screening results cannot be used as evidence in court or for license suspension without a confirmatory lab test conducted by an accredited facility. It also requires agencies to preserve samples for independent retesting and disclose all relevant records to defendants. This bill directly affects police officers conducting DUI investigations, defendants in DUI cases, and laboratories performing confirmatory tests.
