In this article we cover everything you need to know about the MOT test including what it is, what it covers, how long it takes and how much it costs.
6 August 2024In the UK, an MOT test is an annual inspection of your vehicle. During the inspection, different aspects of your vehicle are tested, including exhaust emissions, general roadworthiness and vehicle safety. The test certificate should provide drivers with a level of assurance about the safety of their vehicle and other vehicles on the road.
It is a legal requirement in the UK for most vehicles over three years old (four years old in Northern Ireland) to undergo an MOT test. There are only a few exceptions for vehicles on smaller islands, but these vehicles cannot be driven on mainland UK.
The test was first introduced in the UK in 1960. Back in those days, vehicles only had to undergo the test once they were 10 years old[1], a far cry from the three-year mark which is enforced now.
MOT test stands for ‘Ministry of Transport’ test. The Ministry of Transport was once a department of government that was in use from 1919 to 1970. They were the department who introduced the test in 1960.
Since 2002, the part of government that controls and regulates UK transport and roads is known as the Department for Transport. Although the Ministry of Transport is now defunct, the acronym for the test has not been replaced.
Currently, the MOT test certificate is issued by the Driver and Vehicle Standards Agency (DVSA) in the UK. In Northern Ireland, the certification is issued by the Driver and Vehicle Agency (DVA).
As discussed above, a new car needs its first MOT test after it is three years old – or, more accurately,. This is no later than three years from the its date of registration. Your vehicle’s date of registration can be found on your V5C registration document.
After your car is three years old, the test must be carried out on an annual basis. If you have purchased a car from us and downloaded our app, we’ll send you personalised MOT reminders. So, when it comes round to the time of your test, you won’t forget!

If your car fails its MOT, its usually because checks have been carried out and deemed the vehicle as having a ‘dangerous’ defect. If this is the case, you will not be able to drive away from your MOT appointment without having the repair fixed beforehand.
Other defects or issues can mandate a ‘major’ issue on your MOT, these are still often classed as a failure. However, you may be able to drive your vehicle away from the MOT centre if no ‘dangerous’ problems are recorded in the MOT. You should still look to have ‘major’ issues repaired as soon as possible.
Advisory notes are also very common to receive from your test. These are things that testers found during the MOT which you should look to have repaired but do not warrant a failure. Below encompasses everything that we would usually check during an MOT test. We have broken it into two sections: ‘Exterior and under the bonnet’ and ‘Interior’.
During the test, the MOT tester will check that all your exterior lamps and reflectors are in proper working order and in good condition, that they are secure and correctly positioned and show the correct colour when in use. Exterior lamp checks include:
Additionally, pairs of lights (e.g., main and dipped beam headlamps) must illuminate in the same colour, shape and size and should not dazzle other drivers.
Your tyres and wheels will also be checked in terms of:
If your vehicle has run flat tyres, our MOT testers will check that the warning light is working properly.
In an MOT, your steering wheel and components must be in good working condition. Our MOT testers will check:
A car’s front and rear suspension system components will also be checked during an MOT. This can include checking for things like:
With brakes being one of the most important components for safety, it’s no surprise that they are also tested. At Arnold Clark, our MOT tester will check that your brakes and braking system are working correctly by looking at things like:
During this part of the test, an efficiency test is also carried out. This is when our tester physically drives the car and tests the brakes to determine adequate operation and performance.
The exhaust system and emissions are a significant part of the MOT. Your car’s fuel type – petrol or diesel – will dictate the type of emissions testing it receives. It will then be inspected to ensure it meets minimum exhaust emission criteria for the particular fuel type.
The exhaust system is inspected to check that all components are present, in good condition and proper working order. Our tester will check the exhaust for the following:
The general condition will be checked on the exterior, under the bonnet and under the car. This is to check for excessive corrosion or wear on specific areas of the body. Testers will also check for sharp edges on or around the vehicle’s body to mitigate injury. Other components checked include:
Any electrical equipment and wiring which is visible will also be inspected during an MOT. This will include testing of the battery.
Doors will be inspected to ensure:
Registration plates allow cars on UK roads to be easily identified and are used by the DVLA to register all vehicles. During an MOT, our tester will check the general condition of your number plate to certify:
Another thing inspected during an MOT is your Vehicle Identification Number (VIN). Composed of 17 characters, both capital letters and digits, a VIN acts as a distinctive identifier for the vehicle. Our testers will check that a single VIN is shown on your car.
There are some exceptions to this, for example, with multistage build vehicles. You can check the GOV.UK website for more advice.
Having windscreen and wipers in good condition and proper working order is essential for a driver to have a proper view of the road ahead. This is another important part of the MOT. The windscreen and wipers will be inspected to check:
During an MOT, your speedometer will be inspected to ensure it illuminates correctly and is legible to the driver. Some damage to the dashboard which houses a speedometer can be acceptable if the driver is still able to read their speed.
The interior mirror is checked at the same time as other rear-view or indirect vision devices. It is checked to ensure it provides an adequate view of the rear to the driver.
Seats are examined during an MOT to confirm that:
Seatbelts are inspected to confirm that:
Your car’s horn will also be checked. It’s a very important, yet sometimes overlooked, component within a vehicle. It alerts other road users of your presence. During an MOT, your horn will be examined to ensure that:
In 2018, emissions tests became a part of the annual MOT test. They include an exhaust emissions test because this plays a part in moderating the levels of harmful pollutants released into the atmosphere by our vehicles. This is also a question asked in the driving theory test.
Theory Test Question: Why do MOT tests include an exhaust emissions test?
Answer: To help protect the environment against pollution.
During the exhaust emissions test, the MOT tester will measure the amount of carbon monoxide and hydrocarbons in your vehicle emissions. If you drive a diesel vehicle, the MOT tester will also check for levels of nitrogen dioxide. There are certain vehicles which are exempt from official emissions testing as of the time of writing. According to GOV.UK, these include:
However, this may change in the future.
Usually, an MOT takes between 45 minutes to an hour. However, there are various factors that can influence how long the test takes. For example, if your vehicle fails the test, repairs are likely necessary. The time taken is then dictated by the complexity of the repair work.
Rather than waiting around for the test to be completed, you should book an MOT for first thing in the morning, drop your car off and pick it up at the end of the day. This will give the garage enough time to carry out the test and any potential repairs if needed. Sometimes, you may need to leave your car with a garage overnight.
At Arnold Clark, an MOT will cost you £54.85 and, with over 150 dedicated services centres across the UK, it’s not hard to find us.
