The WA road system has been divided into ten (10) heavy vehicle road networks (listed to at the bottom of this page)..

Network 1 is the largest and covers all roads statewide with a list of exceptions. Networks 2 to 10 progressively become more and more restricted. Network 10 is the smallest and covers road train combinations between 36.5 and 53.5 metres in length (link to networks).
