State of Iowa v. Jeffrey John Flynn

Summary

The court held that an officer who requests a chemical breath specimen from a motorist must comply with Iowa's implied-consent procedures when the statutory triggering conditions exist. Because Flynn was under arrest and had failed a preliminary breath test showing an impermissible alcohol concentration, the officer was required to make a written request and provide statutory advisories before seeking the chemical breath test. The court affirmed suppression of the test result and remanded the case.
