How many vehicles can I have on my account?

You can link as many vehicles as you like to your account.

When a car linked to your account travels without a correctly installed tag, you'll be charged a video matching fee per toll point.  You can reduce your fees by making sure every vehicle has a correctly installed tag.

A tag can be moved between vehicles so long as they're both in the same vehicle class. You can also order extra tags so that each of your vehicles has one.
