30mph speed limit.
Posted: Sun Dec 06, 2009 7:19 pmCan anyone tell me why the figure of 30mph was used when a lower limit was created?
I suspect that this represented something like half of the maximum speed of the average vehicle at the time but there must have been a better reason to choose 30 than that.
