Lord Bradshaw – 2014 Parliamentary Question to the Department for Transport

The below Parliamentary question was asked by Lord Bradshaw on 2014-04-03.

To ask Her Majesty’s Government whether particulate filters fitted to road vehicles are subject to testing to ensure that those devices remain in good working order.

Baroness Kramer

The annual roadworthiness tests include a test for diesel smoke, using an opacimeter, which is intended to detect a diesel particulate filter that has suffered a mechanical failure or which has been removed from a vehicle. The Department has amended the MoT testers’ manual so as to include a visual check to confirm that a diesel particulate filter is present where one was fitted as standard by the vehicle manufacturer.
