How HCV CVRT Defects Are Classified, According to the RSA

As a long-established commercial vehicle testing company, we take care of many HCV CVRT tests every week. And in the name of transparency, we like to bring you blogs like this one to demystify what’s involved and better prepare you for what you might experience when going through the process.

In this article, we examine the defects that are picked during a typical HCV test and how they’re classified. There are a variety of reasons why your commercial vehicle might fail a test like this, each of which falls into a particular category. So, let’s take a moment to look at the three main classifications.

Category #1 - Minor Defects (MiD)

The first category of HCV test defect is the Minor Defect (MiD), which according to the Road Safety Authority’s manual on the subject states, is a technical defect that has no significant impact on the vehicle’s safety. This classification also covers a selection of other minor non-compliances.

Category #2 - Major Defects (MaD

The next category used in HCV testing is a Major Defect (MaD), which is more serious, as it’s classified as a defect that may impact the vehicle’s safety, as well as putting other road users at risk. This category also covers more serious non-compliances.

If you get a MaD defect, you are legally able to drive the vehicle away, on the proviso that you have another test booked.

Category #3 - Dangerous Defects (DD)

The most serious of the flags that can be thrown up during an HCV CVRT test is the Dangerous Defect (DD), which essentially makes the vehicle unroadworthy. 

In the event of a DD, the RSA deems the vehicle to be a danger and not able to be driven under any circumstances. If you do so and are caught by the Garda, you risk penalty points and a court appearance. 

Should your vehicle receive a DD warning during your HCV test, the tester is required by law to affix a ‘Fail Dangerous Notice’ to the windscreen, but on the passenger side and in a way that does not obscure the driver’s view.
