Authorizes motor fuel tax rate changes based on certain department of transportation expenditures

HB 2156 establishes a Joint Committee on Transportation Oversight to monitor Missouri's Department of Transportation (MoDOT) spending. The committee, composed of legislators and state officials, reviews MoDOT's annual financial reports submitted by December 31 each year. These reports must include an independent audit, summaries of transportation funding, and MoDOT's performance publications. The committee can make recommendations to MoDOT but cannot alter transportation projects or priorities, focusing solely on oversight and transparency.
