A valid AutoPASS contract and a tag in your vehicle will give you a discount at all toll stations marked "AutoPASS". 

Contact a toll service provider to get an AutoPASS toll tag and enter into an agreement. The AutoPASS tag will arrive by post.

Which toll road company should I choose?

You may enter into a primary agreement with any toll road company that issues toll tags. For example, you may choose the company that administers the toll stations you most frequently pass.
