1 week, 1 hour, 1 day - its out of rego its out of rego.
its not legally allowed on the road - how is that the cops fault? they gave you a fine for doing the wrong thing regardless of reason.
the cop did their job.
anything can happen - if you even had a not at fault accident - you had no CTP cover. you would not only be out of pocket financially from not having any CTP cover to help pay for any injuries received - if you had full comp cover, that insurer can deny you any claim also.
dont want to sound harsh - but thats not the hwy patrol's fault!!!
