2020 MOT Statistics Revealed

We made a freedom of information request to the DVSA to find out:

  • In 2020 which top 10 vehicles (by make and model) were most likely to fail the most MOT test?
  • In 2020 what were the top 10 MOT advisory notices issued?
  • In 2020 what were the top 10 reasons for MOT failures?
  • In 2020 how many MOT tests were carried out in total?

We have presented the data returned to us by the DVSA in this blog post, this information could be especially useful to used car owners that are due an MOT shortly and want to be better prepared.

Data notes for top 10 reasons for MOT failures

  • All figures are for vehicles as initially presented for test (Failure and PRS type Reason for Rejections are included).
  • A failed test commonly has multiple failure items.
  • % of tests = Number of tests with one or more failure items in defect category / total tests.
  • % of defects = Total defects in category / Total defects for all categories.
  • Average defects per Initial Test Failure = Total failure items / (Total tests with Fail result + Total tests with PRS result).
  • Overall Volumes for 2020 have been impacted by the Expiry extension exercise. Test were at a lower level April-July, and rose monthly levels higher than in previous years thereafter.

Data notes for in 2020 how many MOT tests were carried out in total?

Due to the Coronavirus pandemic and the beginning of Lockdown, on 25th March 2020 the DfT announced an MOT expiry extension programme, to take effect from 30th March 2020.

Whilst testing continued through the following months at a lower level, and started back towards normal levels later in the year, there was already a small reduction in test volumes prior to the announcement, likely due to some VTS ceasing testing, and to some vehicle owners having already decided to not to leave home, so no longer travelling.
