OSOW

Oversize Overweight

Motor Carriers who haul loads that exceed Missouri's legal weight and size requirements must obtain Oversize Overweight permits.

OSOW permits give specific routes and special requirements the carrier must follow, when using the Missouri state highway system.

Please note: MoDOT takes seriously its responsibility to keep motor carriers' account information private. We can only discuss accounts with those people appointed as official contacts by the companies we serve.
