Requires the department of transportation to conduct a study on increasing interstate speed limits to seventy-five miles per hour

HB 2583 requires Missouri's Department of Transportation to study increasing interstate speed limits to 75 mph on Missouri's designated interstate highways. The study must be completed by August 28, 2028, and report findings to the governor, House Speaker, and Senate President Pro Tempore, including potential solutions for any safety concerns identified. This bill directly affects the state's transportation agency and future speed limit decisions on interstate roads. It is a procedural study bill with no immediate policy change, focusing solely on gathering data before any potential speed limit adjustment.
