DO NOT ATTEMPT FREE RIDING
From the 1934 Wills Cigarettes 'Safety First' album.
"The Road Traffic Act makes free riding a punishable offence. It is, however, not only because it is illegal that this practice should be discouraged; it is also highly dangerous. Quite recently two children who, unknown to the driver, were taking a free ride on the running board of a motor coach, struck a lamp post and were injured when the coach swung in towards the kerb. The two children in our picture are in great danger, for the deaths of children and adults (who slip and fall from the back of a fast moving vehicle, and are run over by following traffic) are almost daily occurrences."
