What happens if I use a bizz in a vehicle that isn't registered on your account?
If you use a bizz in a vehicle that isn't registered with your issuer and therefore doesn’t appear in My Account, the vehicle’s license plate will still count as one of your five allowed vehicles.
If you want to avoid using the bizz the next time you cross the bridge in the same car, you can manually add the license plate to your account afterwards. On your next trip, you'll still receive the discounted price – even without the bizz.
