like 80 and over should keep to the left lane unless overtaking.
under a certain speed within so much of the curve.

Since you're quoting, could you also quote your source?

Not trying to be a smart arse, (ahem) no really, I want to know.

Would be nice if you if you could also quote the document, revision and
