HC Deb 30 June 1972 vol 839 cc432-3W
Mr. Carter-Jones

asked the Secretary of State for the Environment why existing vehicles have not been subjected to BSAU141A standard; if he will publish in the Official Report what methods he has in mind for improving the enforcement of controls over smoke emission from vehicles in use; and if he will make a statement.

Mr. Peyton

BSAU141A is a standard to be reached at the manufacturing stage; it is not applicable to vehicles in use. I am considering the possibility of replacing the present visual smoke check in the annual test of heavy goods vehicles by an instrumented check.
