Chatbot Max: your 24/7 parking assistance tool

Chatbot Max is an interactive tool designed to assist drivers with parking ticket enquiries and the online appeals process. It saves time by helping you decide whether to challenge a parking or moving traffic contravention and guides you on the supporting evidence required.

To use Chatbot Max, you need:

  • your Penalty Charge Notice (PCN) number
  • the contravention code (as shown on the PCN)
  • the reason for your representation

Additional questions may be asked to provide tailored guidance.

Access Chatbot Max (supported only on Safari, Firefox, Google Chrome and Microsoft Edge) 24 hours a day, seven days a week for instant advice.

Chatbot Max supports more than 40 languages. Choose the language you need on the next page.
