The DVSA plans to use mathematical algorithms to spot trends in garage or tester data that are worth investigating, it has revealed.
Describing the work as one of the main focuses for October, Neil Barlow, head of MOT policy at the DVSA, explained that data analysis may include volumes of tests in a given time, failure rates or items for the particular vehicles tested.
He added: “We would then combine this with other information to identify situations worthy of investigation, or just to determine a risk rating, which would be used to prioritise our work.
“We still have a lot of work to do on this, but will update you as we progress.”
The DVSA will also be changing the reasons for rejections and advisories this month to ensure motorists can easily understand them.
Latest system changes
In recent weeks, the DVSA added a link to the Society of Motor Manufacturers and Traders vehicle safety recalls page on the testing service.
It also added brake weights of more vehicles to the system.
Changes have been made to the test quality information part of the testing service, allowing users to choose either one or three months’ worth of data.
These include the number of tests, the average age of vehicles tested, the average test duration and failed test percentages.
Users can now see a breakdown of test failure component categories, including figures for the site averages.
