Is this sensible libertarian thinking?

I was listening to the radio today while driving, and I heard a caller – who was a truck driver – (not the host!) say that speed limits are an abridgment of his rights, and as a libertarian, he felt that no law should take away his right to drive as fast as he wants.

I believe that his theory was that (a) he bought the truck, and (b) his livelihood depended on driving quickly to his destinations. No law should stand in his way.

This was new to me. Is “no speed limits” a tenet of modern libertarianism?
