The mot scheme was brought into effect in the early 1960’s and was primarily designed to improve road safety, it has evolved greatly through the years mainly because of global warming legislation demanding the restriction of exhaust gases.
The actual mot test takes on average 45 mins depending on the age and type of car
Assessement of vehicle components
assessement of components with regard to wear Simply because it is actually not really practicable to put down limits of wear and tear as well as tolerances for just about all types components on different models of automobile, mot testers are expected to make use of experiance and judgement is definitely assessing the actual condition involving the component. The main requirements to be used when making such an assessement are whether the component seems to have arrived at the stage where it is obviously very likely to affect detrimentally the roadworthiness of the vehicle. whether the condition of the component has obviously reached the period when renewal , car repair or even modification is actually required.
No rules means no consistency …
With no rules on advisory notes,
everybody is right, nobody is wrong!
Unsurprisingly the resulting inconsistencies
confuse motorists who don’t
realise that the advisories notes with
their pass or failure certificates have
no ‘official’ stamp of approval.
Some mistakenly believe that the
MOT is a gilt-edged assurance that
their vehicles are safe for another
year: So an advisory list of potentially
defective items, accompanying
the pass certificate causes confusion!
Of course, not. all Testing Stations
‘load up’ the advisories to get more
work. Many carefully explain to their
customers the issues involved and
degree of urgency (or not) of different
advisories. Sadly others are less
honest and use advisories to ‘up-sell’
and increase revenue.
Altogether; last year there were just
under 30 million advisory notes.
The· most were on tyres only just
meeting the I .6mm requirement,
with 4 million associated with passes,
and another 2.5 million with failures.
Slight wear in ball joints accounted
for 2.3 million advisories, with just
acceptable brake pad/lining wear
coming third at just over a million.
By and large advisory notes fall into
Degree of wear: This gives
the motorist at least a ‘heads up’
if an item has only just passed
the MOT standard. It applies
to tyre wear, disc pad thickness,
wear in steering and suspension
joints and so on. In discussion
after the MOT the motorist
should be given a balanced
view as to how long it might
be before the item concerned
would deteriorate excessively.
Corrosion: This can pose real

have had a go at it with a screwdriver,
or it may be covered with

against future issues, the Tester
might advise of’extensive surface

caveat providing evidence of the
situation ‘on the day’ to refer to
in the future.
