A valid AutoPASS contract and a tag in your vehicle will give you a discount at all toll stations marked "AutoPASS". You can get an AutoPASS toll tag by entering into an agreement with a toll road operator that issues tags.
Those toll road operators that don't issue tags are labelled with an asterisk. Be sure to choose one of the operators without an asterisk. Click the link to the toll road operator's own website to enter into the contract. The AutoPASS tag will arrive by post.
Which toll road operator should I choose?
You may enter into a primary agreement with any toll road operator that issues toll tags. For example, you may choose the operator that administers the toll stations you most frequently pass. See the map on rates and discounts.
