When did double and single yellow lines appear on Britain's roads for the first time? And does anybody know of a website of British Road history, that includes background info to the various rules and regulations?

Couldn't find anything specific to yellow lines, but you'll find everything you didn't realise you didn't know about the British road system at http://www.maths.lancs.ac.uk/~greenrm/roads/index.
