Revised guidance on categorisation of defects issued by DVSA


The DVSA’s guidance on how it categorises vehicle defects in roadside checks and vehicle tests has been updated this week.  The guide outlines the actions to take when roadworthiness defects are found during vehicle inspections.

The changes include:

  • the introduction of tyre pressure measurement at the roadside for single fitment tyres
  • engine malfunction indicator lamp defects and additional notes for emission control system faults
  • extra notes for assessing lighting defects and number plates
  • updates to indirect vision devices
  • new defects for modified seatbelts.
  • The revision record (Appendix A of the manual) has also been updated, which identifies all the changes in the guide.

You can find the revised categorisation of defects document on GOV.UK
