HC Deb 12 February 1965 vol 706 c143W
Sir R. Russell

asked the Minister of Transport what progress is being made in preventing the excessive emission of fumes from the exhausts of motor vehicles.

Mr. Tom Fraser

The development of exhaust control devices in this country and also in the United States continues, as does medical research here into possible dangers to health from exhaust fumes.

Meanwhile, I am continuing roadside checks to combat the avoidable nuisance of smoke from diesel-engined vehicles.
