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.
Starting Monday, Jan. 3, MoDOT Motor Carrier Services will accept applications for oversize overweight loads through our MoDOT Carrier Express online service only.
Allowing agents to focus on troubleshooting and processing of errant applications is expected to improve permit delivery time and telephone hold time.
If you are not a regular user of MoDOT Carrier Express, be sure to access your account between now and January. Visit www.modot.org/mce to login or to find a link to obtain a Customer ID and password. We suggest that the next time you need a permit, you call with the login page on your computer screen so our agent can walk you through the process.
Missouri is the last of the upper Midwest states to require electronic permit application. If you have applied for a permit elsewhere, our online system is likely to work similarly to those of other states.
