Some places in the US use third-parties to enforce traffic laws. I was once in a park and I got a ticket for not coming to a complete stop at a stop sign by a third-party company employed by the park. I looked into the legality of receiving a ticket from someone who is not a cop and I was under no legal obligation to pay it. However, they can ruin your credit if you refuse to pay, so I just went ahead and paid it. I did not seek legal advice and maybe I should have, but the fee was less than a lawyer would have cost.
