This matter came under the consideration of a Home Office Departmental Committee a year ago. Their report did not suggest that there was any such evidence of injury being caused by exhaust fumes to the health of drivers and conductors or of persons using the highway as would justify legislative action. I may, however, add that the examiners appointed under the Road Traffic Act, 1930, and the Road and Rail Traffic Act, 1933, are required to look for defects in exhaust pipes in the public service vehicles and goods vehicles which they examine.
