Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 5 February 2018 to Question 125528, Motor Vehicles: Carbon Emissions, for what reasons different systems are in place for tackling smoky and excessive exhaust emissions from (a) lorries and buses and (b) private cars and motorcycles.

The Driver and Vehicle Standards Agency (DVSA) reporting system outlined in the answer of 5 February to Question 125528 applies to lorries and buses, because some of DVSA’s powers and responsibilities are specific to lorries and buses. For example; the DVSA has powers in respect of the enforcement of commercial road transport offences but does not have the same enforcement powers in respect of private cars or motorcycles. In all cases it remains the user’s responsibility to ensure the vehicle continues to meet these emissions standards at all times while in use.
