HRS §263A-1
Flying means you agree to alcohol testing
If you fly an aircraft in Hawaii, you automatically agree to a breath or blood test for alcohol. You can choose breath, blood, or both. A police officer can only ask for the test after arresting you and telling you the penalties.
The statute, as written — Implied consent of operator of aircraft to submit to testing to determine alcoholic content of blood

(b) The test or tests shall be administered at the request of a law enforcement officer having probable cause to believe the person operating or in actual physical control of an aircraft is under the influence of intoxicating liquor only after: (1) A lawful arrest; and (2) The officer has informed the person of the sanctions of section 263A-5.
