Relating to transportation.

HB 2159 requires Oregon's Department of Transportation (ODOT) to study whether uniform standards for speed bump height and markings should be developed. The study must examine possibilities for standardization and report findings to transportation committees by September 15, 2026. This bill expires on January 2, 2027, meaning it only directs a temporary study with no immediate policy changes. It directly affects ODOT and future legislative decisions, but does not create new laws or regulations.
