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 no tag in vehicle fee or vehicle matching fee per trip. 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.
