Relating to transportation.

HB 4175 requires Oregon's Department of Transportation (DOT) to study whether uniform standards for speed bump height and markings should be developed. The study must examine the feasibility of creating consistent guidelines for speed bumps across the state and report findings to legislative transportation committees by September 15, 2027. The bill does not create new standards but may lead to future legislation based on the DOT's recommendations. It expires on January 2, 2028, meaning the study must be completed before this date.
