There is no difference in the rendering, which seems a bit silly.

I find that the tertiary roads round here are the same as unclassified,
but are usually wider, and have dashed lines down the middle for their
entire length.  In Britain, they actually have the designation "C",
which usually doesn't appear on road signs.

is an example near where I live.  Kilmardinny Avenue and Manse road are
both tertiary roads.  They are like the biggest of the wee roads in an
area which join bigger roads.  For instance, Manse Road joins the A809
with the A81 in this case.
