** The CDOT Permit Office has launched a new oversize/overweight permitting system. The new system (COOPR) is located at https://coopr.codot.gov. Please update your bookmarks. COOPR allows for 24/7 access, fleet management and self-issue capabilities on some permits, and a routing component to assist Annual Permit holders with determining safe routing for their loads. CDOT no longer accepts applications by fax.

 

** Chain Law in effect - September 1 - May 31.

Important Reminder:

  • The new permit system has decreased the turn around time for the issuance of Oversize/Overweight permits. We will not guarantee that applications received after 3:00 p.m. (MT) will be processed on the same business day. Applications are processed in the order in which they are received.

Our busiest days of the week are typically Mondays and Fridays. We recommend that applications be submitted early in the day to avoid delays.
