Finding Hemingway
You mean I didn’t have to pay the fines I got speeding in the us?
I doubt you would have to. Motor Vehicles here would have no authority for collection of them. If you get ticketed in Canada you can't get new plates or registration without paying up. That isn't the case for out of jurisdiction fines. Additionally out of country collection is much more difficult. The worst is some collection agency could try to impact your credit rating for non payment. if that's any area of concern.
A word though is if you have demerits, and if that's a concern, and the US ticket sets you over a limit you will pay more for insurance and your insurer will know about it. But you are not forced to pay the fine. It goes to collections, and a possible report on your credit rating for non collection. Myself I could care less about the latter. Credit rating is uber solid and I never need it anyway.
