Question to the Department for Transport:
To ask the Secretary of State for Transport, what recent assessment he has made of the effect of MOT testing on vehicle emissions on air quality.
Specific analysis relating to the impact of the MOT test on air quality has not recently been conducted by the Department. Emission limits for vehicles undergoing MOT testing have previously been set at a European level, most recently by Directive 2014/45/EU. These regulations were transposed into UK law by the Motor Vehicles (Tests) (Amendment) Regulations 2017.
