HB 3766 amends Oklahoma's DUI statutes to update Class B3 criminal offenses, specifically adding two DUI-related offenses: third or subsequent DUI convictions (item 21) and driving with a blood alcohol concentration of 0.15% or higher (item 22). The bill also updates statutory references across multiple DUI-related sections (e.g., Sections 11-902, 11-904, and 11-906.4) and clarifies that metabolite presence alone cannot be used as evidence for DUI of controlled substances. It further specifies requirements for testing controlled substances and allows independent evidence in DUI cases. The bill affects individuals convicted of certain DUI offenses and updates legal references for law enforcement and courts.
