Back in the 1960s, before the touchy-feely, child-centred Green Cross Code was thought of, we had the kerb drill:
"At the kerb, halt! Look right, look left, look right again. If all clear, quick march!"Now, with the poster above, the Liberal Democrats are trying to revive it. Could there be a grown up in charge of our campaign after all?
You can see the drill in action in this first Ministry of Information film:
And see an adult being taught it by a squeaky-voiced Forties child in the second.
