Yellow Lines

Broken line - no waiting for less than the working day
Single line - no waiting for the working day (7 a.m. to 7 p.m.)
double yellow lines - no waiting for longer than the working day. This
does not automatically mean at all times.

This is what I thought, but I'm told I'm wrong!

And, indeed, http://www.highwaycode.gov.uk/signs09.htm specifically says
"Double yellow lines mean no waiting at any time, unless there are signs
that specifically indicate seasonal restrictions." So it's obviously
changed since I last learnt the Highway Code (must get an up-to-date
copy!).
