You can track your mileage against the mileage you declared in the RAC Black Box app.
We'll let you know if you're getting close to the mileage you declared, and you can just update that yourself in the app. You'll get a quote to check what you need to pay, then make the change right then and there. Easy.
Please be aware there is a maximum mileage we will cover. If you reach this limit, you may not be able to add more. We can discuss your options when you chat to us.
