Highways in Western Australia include both roads that are named as a highway, and roads that have been declared as a highway under the Main Roads Act 1930. The standard of highways range from two-lane roads, common in rural areas, to controlled access, grade separated freeways in Perth.
In legislation, a highway is a type of road controlled and maintained by the state road authority, Main Roads Western Australia. Any road or section of road may be proclaimed a highway by the Governor of Western Australia, on the recommendation of the Commissioner of Main Roads, under Section 13 of the Main Roads Act 1930. Section 14 of the act allows for the creation of new highways. The highway number does not correspond to a road route that may be allocated to the highway, and some highways are not part of a numbered route.

Road routes with highway names
Highway 1 is a route that circumnavigates Australia, joining all mainland state capitals, via roads numbered 1, M1, A1, or B1, as some states use an alphanumeric route numbering system. In Western Australia, most of the highway is designated as National Route 1. However, the sections in the north-east and south-east of the state that are concurrent with the National Highway routes from Perth to Adelaide and from Perth to Darwin are designated as National Highway 1.
