Safety on Victoria's Roads—Regional Road Barriers

Appendix B. Road classification

In Victoria, rural roads are classified according to the Statewide Route Numbering Scheme, also known as the MABC classification. Figure B1 describes the differences between rural road categories.

Under this system, each road is given a letter (M, A, B or C) and an identifying number. The letter reflects the quality and function of the route. The number assists drivers to navigate rural roads.
