Motor Vehicles: Testing
(asked on 6th June 2022) - View Source
Question to the Department for Transport:
To ask the Secretary of State for Transport, with reference to the Answer of 21 March 2022 to Question 141263 on Motor Vehicles: Testing, what estimate he has made of the initial MOT failure rate for (a) diesel, (b) petrol, (c) plug-in hybrids and (d) battery electric vehicles in each of the last five years, by age of vehicle.
The tables below show the initial failure rate for all MOT vehicle classes from Class 1 (small motorcycles) up to and including Class 7 (goods vehicles between 3,000kg and 3,500kg). It is possible that some older vehicles have had the fuel system converted.
The Driver and Vehicle Standards Agency does not hold data to differentiate between hybrid vehicles that are Plug-In, and those which are not.
