How To Check Missouri Restrictions
Start with the MoDOT Motor Carriers Map and turn on Size and Weight Restrictions / Oversize Overweight. That is the main live state source for restricted and closed segments.
Even if the route looked clear earlier, check posted weight-limit signs on the road or bridge before you commit to the segment.
If pickup or delivery uses county roads for the last miles, confirm with the county road-and-bridge or highway office. Missouri does not publish one statewide county status page, so local confirmation matters.
If the route is still unclear, use MoDOT OSOW / Motor Carrier Services for official carrier guidance.
Important Limitation
Current restrictions should be verified directly on the official sources listed below. Missouri should currently be treated as a manual route-verification state.
