An intensive campaign to make London children aware of the dangers of the road, and to teach them how to avoid them, this now going on under the guidance of the Metropolitan Police. Lessons on road safety are first of all given in school class rooms and the children are taken into the street with policeman teachers to put the lesson into practical effect. Picture shows: In South Square, Gray's Inn, London, the children see "Safety Sam" demonstrate to them the right way to cross the road. 4 November 1946
