No one seems to know what it is, why we carry it, or if it needs to be renewed.
Is it possibly the system that pre-dated the CVOR system?
Is it still valid after 24 years?
Are there any "older" drivers (no disrespect intended, I value your knowledge) that remember or know of this permit?
You can always go to one of the MTO weigh scale stations and they will run the number on their system...CVOR's are now on an annual renewal...so I would think your number is long since expired...
