Trunk: Wide, high-speed roads with limited cross traffic. Usually dual
carriageways in urban areas.

Primary: In rural areas, a major road between cities which does not
meet motorway or trunk standards. In urban areas, a major road which
is particularly long or heavily traveled, or the extension of a road
which is primary outside the urban area.

Secondary: Other major urban streets not meeting the standards for
primary. Also highways in rural areas.

Tertiary: City streets that have a median, more than two lanes, and/or
moderate traffic, but are low speed and primarily residential, or
locally-maintained rural roads that are important for local
navigation, such as connecting a shortcut between two nearby highways
which don't intersect.
