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.

The tools on these pages help both beginners and seasoned trucking companies operate safely and profitably.

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.
