Most of the July 2026 changes update the way testers inspect or classify particular items. They don’t completely change how the CVRT works, but they may affect how certain defects appear on a test report.
The main changes include:
Registration plates – the guidance now allows for the green flash that may be displayed on registration plates for zero-tailpipe-emission vehicles
Vehicle identification numbers – VIN details may now be verified using an OBD scan tool
Vehicle repairs and modifications – the guidance on when a modifications report is required has been updated. The LCV manual also includes a new major-defect reason where a required report for repairs carried out hasn’t been provided
HCV authorisation plates – new plate templates have been added for vehicles operating under national weights and dimensions authorisations
Brake components – the wording covering deteriorated brake linings and pads, along with cracked brake drums and discs, has been updated
ABS and EBS systems – the testing method now includes additional guidance on using an OBD scan tool where possible
Vehicle glass – one reason for failure relating to glass condition has changed from a major defect to a minor defect
Wheel bearings and stub axles – the reasons for failure now refer to rough wheel bearings and kingpins that are seized in the stub axle
Tyres – an exposed tread-wear indicator and any tyre with a flat spot are now specifically listed as major defects
Passenger seats – a new major-defect reason covers too many seats or seats positioned in a way that doesn’t comply with the vehicle’s approval
eCall systems – the LCV manual now contains a new section covering eCall inspection where the system is fitted and applicable
