Sweeper - A long turn or curve.

Decreasing radius Corner - A corner that has a smaller radius in the last half of the turn.

Increasing Radius Turn - A turn were the radius of the first part of the turn is tighter than the second half.

Constant Radius Corner - A corner that has a constant radius through the turn.

Technical Turn - A turn that can't be negociated without either braking before it or sliding through it.

Hairpin Turn - A corner that exceed 100 to 120 degrees.

Note these are street luger terms, but they seem applicable.

 

From anothe site

"Chicane: Also called an "S curve" or "Ingress/Egress" but I prefer to call it Chicane, as this is the sound your ego makes when it is ripped from your body "Chicane!""

 

FWIW I have been on highland valley road, I guess you can call the majority of turns sweepers, but I tend to reserve the term for longer faster turns, like Montezuma Grade or Angeles Crest.

Certainly there are some sweepers on Highland valley road and a couple sub 20mph hairpins, too.

It is not my favorite road because of visibility, cross traffic, and squashed oranges..

But great turns and an exciting pace, especially if you are trying not to get too far behind Todd's Jackal.
