Motor carriers; creating the Motor Carrier Public Safety Enforcement Act; effective date.

HB 2603 transfers enforcement authority for Oklahoma's motor carrier regulations from the Corporation Commission to the Department of Public Safety. It affects commercial trucking companies, enforcement officers, and state agencies by shifting responsibility for roadside inspections, weigh stations, and compliance checks under specific statutes (including the Weigh Station Act and Trucking One-Stop Shop Act) to the Department of Public Safety by June 2027. The bill creates a transitional task force to oversee the shift, requiring cooperation between agencies and setting a two-year transition period from July 2026 to June 2027. Key provisions include mandating the Department of Public Safety assume full enforcement authority, requiring interagency agreements during transition, and modifying rules for vehicle seizures and permit compliance.
