The permit pages
Missouri-specific requirements
One-stop shop: MoDOT Motor Carrier Services administers intrastate authority, IFTA, IRP, and OSOW permits in a single agency via the MoDOT Carrier Express portal; legal height is 14 ft on interstates and designated routes vs 13.5 ft elsewhere.
The permit office and MISS
The MISS Oversize/Overweight Permit Section handles applications and issues permits for loads above the legal size and weight limits. The office's contact and the online permit system are on this page as sourced fields.
The permit types Missouri issues
Single-trip permits cover one non-divisible load over the legal limits. The annual option is for carriers that move over-dimensional loads repeatedly: one yearly fee covers repeated moves inside a published size and weight envelope. Our Missouri oversize and overweight page carries the full fee tables, escort thresholds, and the superheavy process.
Curfews and local restrictions
Movement curfews are set locally and published per route. The responsibility sits with the permit holder: check the current restrictions before each move, not the copy printed on a permit you pulled last season.

- Yes, for carriers that move over-dimensional loads repeatedly. One yearly fee covers moves inside a published size and weight envelope. Details and the sourced figures are on our Missouri oversize and overweight page.
When can permitted loads not move in Missouri?
