OVERSIZE OVERWEIGHT PERMITS
Motor Carriers who haul loads that exceed Missouri's legal weight and size requirements must obtain Oversize Overweight permits.
OSOW permits outline specific routes and special requirements the carrier must follow, when using the Missouri state highway system.
MoDOT Motor Carrier Services accepts applications for oversize overweight loads through our MoDOT Carrier Express online service only.
