To ask the Secretary of State for Transport (1) whether he will provide in the regulations for the testing or replacement of the three-way catalyst in cars after eight years' use;(2) if he will make three-way catalyst emission testing one of the conditions for granting an MOT certificate.

We are now consulting on proposals for an emissions check for introduction into the MOT test next year. We are proposing that this should include vehicles equipped with catalytic converters. A vehicle with a seriously defective catalyst would not pass the test.
