 "firstOffenseIidNote": "For a first OWI revocation, Iowa Code § 321J.4(1) requires the Department of Transportation to require an ignition interlock device only 'if the defendant seeks a temporary restricted license'; § 321J.4(8)(a) separately allows the court to order interlocks on conviction. A post-reinstatement interlock requirement applies under § 321J.17(3) only to a second or subsequent revocation. A medical waiver is available for offenses on or after Jan. 1, 2025 (Iowa DOT).",
