New MoT standards trigger air quality improvements, says DVSA

New MoT standards trigger air quality improvements, says DVSA

The number of cars failing emissions tests has more than doubled since the new MoT introduced stricter emission rules on 20 May, according to the Driver and Vehicle Standards Agency (DVSA).

Following the changes, more than 744,592 cars have failed the emissions test. The cars have either been taken off the road or fixed, helping to improve air quality. That compares to 350,472 cars failing the emissions test during the same period in 2017.

Since 20 May, a total of 238,971 diesel cars and 505,721 petrol cars have failed the new emissions test. That compares to 58,004 diesel cars and 292,468 petrol cars during the same period in 2017.

The new test has also seen a 448% increase in the number of diesel vans failing. The DVSA’s figures show an increase from 3,585 in 2017 to 19,648 over the same period in 2018.

Since 20 May, a vehicle gets a ‘major fault’ if the MoT tester:
  • Can see smoke of any colour coming from the exhaust
  • Finds evidence that the diesel particulate filter (DPF) has been tampered with - it captures and stores exhaust soot to reduce emissions from diesel cars.

A ‘major fault’ means the car must be repaired immediately, and it then needs to pass an MoT retest. There is a fine of up to £1,000 for driving a vehicle without a valid MoT.

Gareth Llewellyn, DVSA chief executive, said: “DVSA’s priority is to protect everyone from unsafe vehicles and drivers. We are committed to making a real difference to those in society whose lives and health are blighted by poor air quality.

“Since introducing the new tighter MOT emissions test in May, nearly 750,000 vehicles have been taken off the road or fixed.”
