In the UK every vehicle over three years of age has to have an annual inspection. This inspection looks at a variety of point so the vehicle to ensure that it is safe and roadworthy. Firstly we will cover what is looked at during a MoT and secondly what MoT equipment is required to carry the test out.
Some of the points that are look at are very straight forward such as checking the VIN number is clearly readable, that the registration plate is easy to read and in the correct format and that all mirrors are present and in good working order. But some of the other sections require specialist equipment to test them properly.
Some of the more technical parts that are inspected include the entire exhaust system, Co2 emissions, brakes, complete fuel system, steering and suspension as well as lights. Some of the checks performed are merely a visual check to ensure all is present and working correctly but in the case of area like the Co2 emissions a special piece of equipment is required to determine the Co2 emissions of the vehicle.
To test the Co2 levels you will need an Emissions Analyser, the test will advise the person performing the test what the hydrocarbon emissions are. If they are above the allowed limit the vehicle will fail. There are three main types of analyser, a petrol one, a diesel one and combined petrol and gas one.
To test the brakes and MoT test station will need to have what is sometime referred to as a rolling road. For this piece of machinery there are two main models, ones that will test class 4 brakes and one that tests class 7 brakes.
To enable the tester to get under the vehicle with easy to check the exhaust and other such parts more easily a vehicle lift is required. Depending on the type of vehicle being tested the lift required will vary, there are a number of options such as the four post lifts which can accommodate class 4 vehicles which can hold up to 4 tonnes and has a platform area of 4560mm and two class 7 ones holds up to 4 tonnes and has a platform area of 5200mm and the other up to 5 tonnes with a platform area of 5700mm.
Another piece of gadgetry needed is a headlamp aim tester; this will help the station assess the correct direction of the headlamps even during bright daylight. Some stations even have a completely automated testing lane for class 4 and 7 vehicles.
All of these plus the expert eye of the inspector are able to determine the vehicle roadworthiness, if the vehicle fails on any part of the test a new MoT certificate will not be issued until the issues are resolved. In some cases the station may issue you with a new MoT certificate but give you a list of warnings or advisory notes. These are points they have picked up on that will need sorting out before the next test or even sooner.
