How many vehicles can I have on my account?

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

If you have an Everyday Account or Commercial Account, you can reduce your fees by making sure each vehicle has a correctly installed e-TAG. When a car linked to your Everyday Account or Commercial Account doesn't have a correctly installed e-TAG, you'll be charged a $0.75 no tag in vehicle fee per trip.

An e-TAG can be moved between vehicles so long as they're both in the same vehicle class. You can also order extra e-TAGs so that each of your vehicles has one.
