§ Mr. Leslie Huckfieldasked the Secretary of State for the Environment what studies he has now made of the efficacy of advertising promoted by his Department to encourage the wearing of safety belts.
§ Mr. Eldon Griffiths:My Department conducts regular surveys to determine the effects of road safety publicity campaigns. In 1971 an intensive campaign in the North East increased wearing of seat belts to about 28 per cent.—almost double the national average, though I regret to say this is falling off.
