MOTOR CARRIER SERVICES

MoDOT Motor Carrier Services helps carriers get the information, credentials and permits needed to start and continue a carrier business in Missouri.  We also enforce safety and economic regulations to help make our highways safe and fair places to earn a living.

Q&A - SPECIAL PERMIT ALLOWING OVERWEIGHT LOADS TO USE INTERSTATES IN MISSOURI

What do I need to do to take advantage of this special permit?

Download and print copies of the special permit document.  Links are available at www.modot.org/mcs. Carry these documents and a complete bill of lading for each load, during operation on Missouri highways.

What does the special permit cost?
Nothing. The special permit is free of charge.

How do I find information about weight restricted bridges in Missouri?

First, know this: Bridge weight limits are subject to change and additional bridges may be posted with weight limits at any time.

When on the road, look for a white sign with black lettering on the right side of the road near each bridge. It is the final word and must be followed, even if other sources (website, vehicle route map) do not match the information on the sign.

Prior to any trip, please visit the MoDOT Traveler Information Map’s special OSOW layer at http://traveler.modot.org/mcm/MotorCarriersMap.html and zoom in on the route you plan to take. If a blue or red box appears in your route, click it to learn whether the highway is width- or weight-restricted at that location.  

The special OSOW layer is not available through the MoDOT Traveler Information Map app. You must use an internet browser to access it.

My truck has three axles. Can I use the special permit?
You can use the permit, however, the gross weight of your vehicle is limited to 10% heavier than the licensed weight of your vehicle. You will be allowed to use interstate highways if you follow all the conditions outlined in the special permit.

SAFETY & COMPLIANCE

MoDOT Motor Carrier Service's Safety & Compliance section encourages compliance with Missouri State Statutes and Federal Motor Carrier Safety Regulations through education and enforcement.

INTERSTATE MOTOR CARRIERS

Motor carriers who are based in Missouri obtain apportioned license plates, a fuel tax license, complete Unified Carrier Registration and obtain other credentials from MoDOT Motor Carrier Services. Most of the programs are renewed annually and most require some form of recordkeeping. See the individual program pages to learn more. 

INTRASTATE MOTOR CARRIERS

Motor carriers who operate only within Missouri's borders obtain operating authority, special licensing to haul houses, household goods, waste products and other credentials from MoDOT Motor Carrier Services. Most of the programs are renewed annually and several require some form of recordkeeping. See the individual program pages to learn more. 

OVERSIZE OVERWEIGHT LOAD MOTOR CARRIERS

Motor carriers that haul loads that are heavier, wider, taller or longer than standard legal limits must apply for a special permit. These permits prescribe specific routes and requirements the carrier must follow when using the Missouri state highway system.

FIGHT HUMAN TRAFFICKING

Human trafficking is a modern-day form of slavery. At its core, it involves the exchanges of goods for services using force, fraud or coercion. Victims are forced into labor or commercial sexual exploitation.

Human trafficking is real and it is a crime.

MoDOT has joined with other state DOTs and the U.S. Department of Transportation to help fight human trafficking.
