HI HB1387

Lowers the legal blood alcohol concentration (BAC) threshold for driving under the influence from 0.08 to 0.05 grams of alcohol per 100 milliliters of blood or per 210 liters of breath

Reduces the "measurable amount of alcohol" range to 0.02 to less than 0.05 (previously 0.02 to less than 0.08), affecting how intermediate alcohol levels are treated in DUI proceedings

Lowers the presumption of not being under the influence from 0.05 or less to 0.02 or less BAC, meaning drivers with BAC between 0.02 and 0.05 may have their alcohol level considered as evidence but without a presumption either way

Applies the new 0.05 BAC standard to both regular operating under the influence offenses and habitual offender charges under sections 291E-61 and 291E-61.5

Effective date set to July 1, 3000 (placeholder date indicating the bill requires further amendment before implementation)
