A Road User’s Guide to the July 2026 CVRT Changes
The CVRT isn’t a test that stays exactly the same forever. The testing manuals are updated when vehicle technology changes or when the RSA needs to clarify how particular defects should be assessed.
New versions of the Light Commercial Vehicle and Heavy Commercial Vehicle testing manuals came into effect in July 2026. So, if your van or truck is due its test, it’s worth knowing what has changed.
What Has Changed in the CVRT?
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
What Do the Changes Mean for Vehicle Owners?
For most drivers and operators, the basic advice hasn’t changed. Your vehicle still needs to be properly maintained and roadworthy when it arrives for its test.
However, the updated manuals give testers more specific guidance on areas such as tyres, brakes, vehicle repairs, modifications and electronic systems. A problem that may previously have been described in general terms could now appear as a more specific defect on the test report.
If your vehicle has undergone repairs or modifications that may adversely affect its roadworthiness, check whether a modifications report is required before presenting it for a CVRT. This does not apply to every routine repair or maintenance job.
This blog is a general summary. You can find the complete changes and download the updated HCV and LCV testing manuals on the official CVRT website.
