HB 308 lowers Alaska's legal blood alcohol limit for driving under the influence (DUI) from 0.08% to 0.04% for blood, breath, and blood tests. It establishes new evidentiary rules: below 0.04% presumes no impairment, between 0.04%-0.08% is considered evidence but not proof of impairment, and 0.04% or higher presumes impairment. The bill affects drivers charged with DUI or driving under the influence, including those with prior convictions at or above the new 0.04% threshold. It also requires breath tests for intoxicated individuals at release from custody and sets an effective date of January 1, 2027.
