Route marker signs
Route marker signs give you directions and information for the route you are:
- approaching

Route numbering
Route numbers identify roads as part of major routes connecting towns and cities. They are there to reassure you that you are continuing in the right direction for your journey.
Route numbers can appear as a stand-alone sign along the road or with a directional sign.

A routes
An A route is a major arterial route in built-up areas that connects routes between cities and towns in rural areas.
B routes
B routes are alternative routes that connect cities and towns. They are normally a longer journey than an A route.
C routes
C route roads also connect road users to cities and towns, but they are not major routes like A or B routes.
M routes
An M route may replace an A route on freeways and motorways that extend out from the city.
