Revised guidance on categorisation of defects

Our revised guidance on how we categorise vehicle defects in roadside checks has been published today, 20 April 2022.

This guide outlines the actions we take when roadworthiness defects are found during vehicle inspections.

The changed rules will be enforced from 1 May 2022. On that day will also publish the revised Enforcement Sanctions Policy.

What’s changed

  • The categorisation of defects has been updated to include new items, notes and amendments in parts 1 and 2 of the manual.
  • There are significant updates to the load security sections, which includes removing the reference to the load security matrix. 
  • There are additional load security defects and notes.
  • Other updates include vehicles missing an obligatory seat belt, electronic stability control (ESC), suspension joints and overrun brakes.

Changes to heavy vehicle Annual Test inspection manuals

We've also published changes to the Annual Test inspection manuals for passenger service vehicles and heavy goods vehicles.

The existing publications are still online and in use until 1 May 2022.
