What is an Oversize Overweight Permit?
State law authorizes the SCDOT Oversize/Overweight Permit (OSOW) office, at its discretion, to issue permits for vehicles and loads that exceed legal size and/or weight limits.
Permitting System Upgraded to Safehaul
The OSOW permitting has been upgraded to a newer version of the software. We’ve posted instructional video on this page to demonstrate how to build and generate a route in the new system. We hope you find the new features useful.

In the event of inclement weather during the winter months, the permit office will be closed per the Governors instructions for state offices in the Richland and Lexington County area. Please visit the road conditions page to find out the condition of the roads in each county you may be traveling in or to.
