An MOT, short for Ministry of Transport test, is the yearly inspection required for most vehicles once they are over three years old. The test checks that your vehicle meets the required standards for road safety, exhaust emissions and general roadworthiness.
If your vehicle does not pass its MOT, you may be able to have it retested for free, or at a reduced cost, depending on where the repairs are completed and how quickly the vehicle is presented for retesting. In many cases, the key timeframe is ten working days, giving you time to arrange the necessary repairs before the retest.
To pass the MOT retest, all failure items identified during the original test will need to be repaired. The MOT refusal document can also be useful for your mechanic or repair centre, as it sets out the areas that require attention.
To qualify for a free MOT retest, the following conditions usually apply:
When these conditions are met, the partial retest is normally completed without an additional test fee. For some types of repairs, particularly those not included in the list below, specialist repair work may be needed. In those situations, you may be able to take the vehicle away from the test centre temporarily so the work can be completed.
Below is a list of common repair items that are often completed within ten working days and may qualify for a free MOT retest:
If your vehicle fails its MOT, you will be given an MOT refusal certificate, commonly referred to as a VT30. The failure information will also be recorded on the MOT database. The sections below explain the MOT fail codes in more detail and outline the areas of the vehicle that may be checked during the test.
Your MOT failure sheet will show codes explaining why the vehicle did not pass. These codes relate to the specific section of the MOT test where the issue was found.
For example, code 5.1.b.1 can be read as follows:
Section 5.
Sub-section 1.
Subject b.
Reason for failure 1.
Section 1: Lamps, Reflectors and Electrical Equipment
Section 2: Steering and Suspension
Section 3: Brakes
Section 4: Tyres and Road Wheels
Section 5: Seat Belts and Supplementary Restraint Systems (SRS)
Section 6: Body, Structure and General Items
Section 7: Exhaust, fuel and Emissions
Section 8: Drivers view of the road
Below are the main MOT sections, sub-sections and subject areas that can lead to MOT failure codes being recorded.
As part of the MOT test, the vehicle’s lights are checked to make sure the lighting and signalling systems are operating correctly. Reflectors are inspected for their position and colour, while important electrical components such as the horn, battery and wiring are also checked.
If an engine warning light is illuminated during the MOT, the vehicle may fail because it can indicate a fault that affects safety, performance or emissions.
If a warning light is showing, it is best to have the issue checked by a reputable garage before continuing to drive.

During an MOT, the braking system is assessed for performance, efficiency and balance, often using a roller brake tester. Brake pads and discs are also inspected.
If brake pads are worn close to their minimum safe level, you may receive an advisory. If they are excessively worn or below the required standard, the vehicle can fail its MOT.

At Shelly Motors Kia Epsom, MOT tests are carried out to help ensure your vehicle meets the necessary safety and environmental standards. Tyre condition is an important part of the MOT, as the right tyres can improve safety, handling and your chances of passing the test.
Tyres are checked for size, structure, load rating, condition and tread depth. Road wheels are also inspected for faults such as cracks, poor fitting, unsuitable compatibility or signs of damage. The tester will look for visible tyre issues including cuts, punctures, tears, lumps and bulges. If the tyre tread is below the legal minimum depth of 1.6mm, the vehicle will fail the MOT and the tyre will need to be replaced.
