§ Mr. Knoxasked the Secretary of State for Transport whether he intends to introduce more stringent legislation to control the emission of exhaust pollution by lorries.
§ Mrs. ChalkerExisting regulations require new diesel engined vehicles to meet a British Standard limiting smoke, and require vehicles in use to be maintained so as not to emit avoidable smoke. The problem is largely one of compliance by vehicles in use. The Department's vehicle examiners—at testing stations and at the roadside—and the police take action against vehicles obviously emitting excessive smoke, and equipment is being developed to assist enforcement officers.
