Bill > SB346

This bill amends Hawaii's driving under the influence (DUI) laws by lowering the blood alcohol concentration (BAC) threshold from 0.08 to 0.05 grams per 100 milliliters of blood or 210 liters of breath. The legislation is based on recommendations from the National Transportation Safety Board (NTSB) and is supported by research showing that lowering the BAC limit can reduce alcohol-related traffic fatalities. The bill modifies multiple sections of Hawaii's Revised Statutes to reflect this new threshold, changing definitions of "measurable amount of alcohol" and "under the influence" to align with the 0.05 BAC standard. The legislature cites supporting evidence, including that over 100 countries have already adopted a 0.05 BAC limit, and a statewide poll showing 62% of Hawaii voters support the reduction. The bill aims to deter impaired driving by creating stricter legal standards for alcohol consumption before operating a vehicle, potentially saving lives and reducing traffic accidents. The changes will apply to criminal prosecutions, administrative license revocations, and definitions of DUI offenses, including habitual DUI. The act will take effect upon approval and does not retroactively affect previous legal proceedings or penalties.
