Rescheduled: OS/OW Permitting Change

The Connecticut Department of Transportation is announcing that it will be switching to a new, online permitting system for oversize/overweight vehicle permits. The new web-based system is expected to be more user friendly, more versatile and is compatible across many online platforms.

To accomplish this switch, the existing system will become unavailable beginning at 3 p.m. to 10 p.m., Thursday, Oct. 12, 2017. During this time, no permits will be generated or issued. Please do not call the permit office as no permits are able to be generated.

Additional Information

Annual Divisible Permits will be valid through date stated on permit. Single-trip permits issued prior to the switch will be valid for the period stated on the permit.

Annual Indivisible Permits have replaced Account Code permits. Users will need to populate the new OS/OW system with their vehicle information in order to obtain the Annual Indivisible Permits at no new cost (for carriers with valid Account Codes), and then begin to request Route Authorizations.

A document summarizing this change will soon be posted to the DOT OS/OW webpage. Questions regarding the switch-over process can be sent by email to:
