Other than sections within the urban areas of Sydney and Melbourne, Hume Highway is generally dual-carriageway (with at-grade intersections and restricted entry from adjoining land), with considerable lengths which are of full freeway standard. Most of these sections are bypasses of the larger towns on the route, where the need to deviate the route to construct the bypass made it practical to deny access from adjoining land and thus provide full freeway conditions. In addition to these bypasses the sections between Casula (in southwestern Sydney) and Berrima (built 1973–92), and Broadford to Wallan (1976), which were both constructed as major deviations, are also of full freeway standard. The entire section in Victoria is categorised as a freeway by government roads authority VicRoads, although a few intersections along the route are not yet grade-separated. The speed limit on the full length of the highway is .
