BRG(C4) Permits (Overdimension/Overweight)

Rules and regulations on the movement of overdimension and/or overweight loads are established by the Commission and Chief Engineer based on State Statute and are on file with the Secretary of State. Permits for this movement may be obtained at Motor Carrier Services, by phone at 800-877-8499. Permits for overdimension loads and non-commercial building movement shall be issued by district office staff for local customers. Permits for all other movement may be obtained at the district by allowing walk-in customers to fax Motor Carrier Services. A permit agent will issue the permit and fax it to the customer at the district office.

District staff should observe the movement of large overdimension and/or extra heavy overweight loads that may cause damage to MoDOT facilities or have a significant impact on traffic movement. Motor Carrier Services will provide copies of all permits issued to the district(s) involved for loads over 16 ft. 6 in. tall, 17 ft. 0 in. wide or 240,000 pounds. District staff should determine which loads are most critical for observance, based on the permitted route. If the permitted move is not made according to the provisions of the permit or any MoDOT facilities are damaged, a report shall be made to Motor Carrier Services.

When permitted loads are moved across more than one district, the original district should notify the next district of problems (if any) encountered with the movement in their area. If the movement was proper and no problems were encountered, it may not be necessary to observe that load in other districts. As part of the quality assurance program, it is recommended that at least 10 percent of the permits issued for larger dimensions and weights (listed above) be observed by district staff.
