It’s crucial for your safety as well as the safety of other road users. To successfully pass this examination, you need to understand precisely what is checked during an MOT.

Introduction to MOT

The MOT test, as conducted in the UK, is a thorough examination of a vehicle’s safety and emissions aspects. It is a mandatory annual assessment to ensure that vehicles on the road are in a condition that doesn’t pose any risks.

In this guide, we will delve deep into the various components that are scrutinized during an MOT test to help you comprehend the process and ensure your vehicle passes with flying colors.

Structural Integrity

  2. Body Condition: The condition of the bodywork, including doors, wings, bonnet, and other exterior elements, is carefully checked. Rust, dents, or sharp edges that might pose a danger to pedestrians are not tolerated.

Lighting and Signaling

Brakes and Suspension

  1. Brake Systems: The braking system is of utmost importance for safety. The MOT test assesses the condition and performance of your vehicle’s brakes, including the brake pads, discs, and hydraulic systems.
  2. Suspension Components: The suspension system, comprising shock absorbers and springs, is reviewed to ensure they are in good condition and functioning as intended.


  1. Exhaust Emissions: Vehicles are subject to emissions testing to verify that they meet the environmental standards. If your exhaust system produces excessive emissions, it can lead to a failed MOT.
  2. Catalytic Converter: The catalytic converter is inspected for any damage or malfunction, as it plays a significant role in reducing harmful emissions.

Wheels and Tyres

  2. Wheel Alignment: The alignment of your vehicle’s wheels is reviewed to ensure it’s within acceptable parameters. Misalignment can result in uneven tire wear and poor handling.

Interior and Safety Features

  1. Seatbelts and Seats: The seatbelts, seats, and their mountings are checked to ensure they are secure and functional.
  2. Airbags and Safety Systems: Modern vehicles come equipped with various safety systems. All these features, including airbags and electronic stability control, are reviewed for proper operation.

Vehicle Identification

  2. Registration Plates: Number plates must meet legal standards, including visibility, condition, and proper font.

Miscellaneous Checks

  1. Windscreen and Wipers: The windscreen should be free from cracks or damage that might impair the driver’s vision. Wipers and washers must work effectively.
  2. Horn: The horn must be in good working order and loud enough to alert other road users.

Once your vehicle successfully passes all the checks, the testing center will issue an MOT certificate, which is crucial for legal road use. However, if your vehicle fails the test, the testing center will provide you with a list of the defects that require attention. You must arrange for the necessary repairs and a retest before legally driving your vehicle on the road.

In conclusion, comprehending what the MOT examination entails is essential to guarantee the safety and roadworthiness of your vehicle. Regular maintenance and timely repairs will not only assist your vehicle in passing the MOT but also ensure a safe and enjoyable driving experience.
