On 20th May 2018 the DVSA changed the way MOT’s are carried out as detailed in our blog post ‘Traditional MOT due to change on 20th May 2018‘. It has now been 6 months since the new changes came into effect and DVSA have released their official data on MOT failures (20th November 2018).
Over 13 million vehicles have undertaken a MOT test since the new changes where implemented on the 20th May. Out of these 1,926,557 petrol (34.6%) and 1,573,492 diesel (33.3%) cars failed their MOT. These figures remain stable showing the average fail rates for this year and last year are the same.
Emissions – Enabling Cleaner Air
More importantly, the data which has been released from the DVSA focuses on the new emissions testing that was introduced with the new MOT. As part of the new emissions testing a vehicle can now fail on
- can see smoke of any colour coming from the exhaust
- finds evidence that the diesel particulate filter (DPF) has been tampered with – this captures and stores exhaust soot to reduce emissions from diesel cars
Since 20 May 2018, a total of 238,971 diesel cars and 505,721 petrol cars have failed the new emissions test which can be compared to just 58,004 diesel cars and 292,468 petrol cars during the same time in 2017. The new test has also seen a 448% increase in diesel vans failing. These have increased from 3,585 in 2017 to 19,648 in 2018.
Importance of Maintenance
The new regulations and statistics clearly demonstrate the important of regular maintenance on your vehicle as this helps to keep emissions within the tested ranges. You should get your car checked as soon as you believe there is a fault or problem with your car rather than wait for your MOT to come around or until the problem get’s to the extend it stops you using the vehicle.
Remember an MOT is a once a year health check for your vehicle but it is only checking the vehicle at the time it is presented for it’s test. It is the responsibility of the owner to ensure their vehicle is roadworthy and up to requirements for the duration of the year.
