Do you have to pay U.S. traffic ticket fines?
If you receive a traffic ticket in the United States that comes with a fine, you should either pay the fine or arrange to attend traffic court to dispute the ticket. For some people, the latter can be complicated.
In a situation like this, hiring a lawyer to attend court on your behalf may also be an option.
Ignoring a traffic ticket is unlikely to work out in your favour, even in states that don’t have a reciprocal agreement with your home province. At best, you’ll be on record in that state as having an outstanding fine. If you ever want to return (or even drive through on your way somewhere else), this could be problematic.
Ignoring a fine could also result in debt collection agency calls.
In the worst-case scenario, if you live in Ontario, ignoring the ticket could lead to a licence suspension. Ontario’s Highway Traffic Act allows a person’s licence to be suspended if they fail to “pay a judgment.” Judgments in jurisdictions outside of the province count too, including in the remaining nine provinces and 41 of the 50 states.
It’s unlikely Ontario is the only province to allow this to happen.
