Think .08 Blood Alcohol Content (BAC) is low for drinking and driving? The Federal Aviation Administration (FAA) established a federal law, Federal Aviation Regulation (FAR) 91.17, establishing a .04 BAC per se standard for pilots while operating an aircraft and it also criminalizes test refusal. It also states that no person may operate or attempt to operate an aircraft while under the influence of alcohol, while using any drug that adversely affects safety or within 8 hours of consuming alcohol which they refer to as the 8 hours from “bottle to throttle” rule.

A list of the FAR can be found at the following website:
