Relating to transportation.

HB 3481 requires Oregon's Department of Transportation (ODOT) to study whether uniform standards for speed bump height and markings should be created. ODOT must complete this study and submit a report with findings and potential recommendations to transportation committees by September 15, 2026. The bill expires on January 2, 2027, meaning it only directs a study with a defined timeline, not implementing new requirements. This affects ODOT and local governments that install speed bumps, but does not change current standards.
