UK mot test?

My understanding of advisories is the same as items changed at a service. Will the item still be legal or within spec in 12 months time?

If the answer is no or not sure then you get an advisory or it is changed. The reason is that a great number of people don’t do anything to their vehicle between services or MOTs.

This in itself creates a lot of waste.

VOSA sound as if they are following the example of The Post Office.

VOSA have been defunct for 10 years or so, it has been part of  DVSA since then.

Their algorithms monitor the test stations.

Pass % has to be within limits for the area, as do the number of advisories.

If  a station is an outlier, it will come under the microscope and trigger a monitoring visit, so testers err on the side of caution and issue advisories, hoping that they have got it "right" so their figures will be OK and DVSA will bother someone else.
 

What if you put broken bulbs in the lamps, leave the (Norwegian) Hi-vis vest out and loosen the battery clamp, or other unexpensive easy to fix faults.
They will not have to check so hard to find enough faults to keep the system happy..

Although there are some like that & pretty sure some would find any excuse to fail a car, but I do feel they are the exceptions rather than the rule. But I would rather have that than there be no checks at all, I have seen the state of some cars that are presented for test & then listened to some of the drivers arguments as to why they should fail, even when the steel is showing through the rubber.

Not really.....

There are about 30 million class 4 MOTs done a year, and the initial failure rate is about 25%, with around 3.4 defects per failure.

So if they have a 90% initial pass rate then DVSA will send someone to have a look, either to confirm that they are located in an anomalous bubble where owners are way above average in their MOT prep, or they are too lenient.

If they are doing their job right, they will be close on the average figures, adjusted for demographic, because of the high number of tests done at a station.

The IT thing is a screen to send the inspectors to a hotspot,they can play the system, but it should work anyway out if they are doing their job right.

There are some jolly statistics to peruse at www.gov.uk/government/statistical-data-s...ta-for-great-britain

I couldn't find anything on advisories, but again, if they never issue an advisory, there has to be something wrong..
