If you are planning a career in the UK’s vehicle testing industry, it's essential to understand MOT test classes. These categories help define which types of vehicles you are qualified to inspect and play a major role in the kind of work you can do as an MOT tester

Whether you're looking to become an MOT tester or simply want to expand your skills, learning the different MOT test classes is a critical first step. In this article, we’ll explain what MOT classes are, how they apply to your qualifications, and how to get trained and certified to work in the most common classes.

What Are MOT Test Classes?

In the UK, all vehicles over a certain age must pass an MOT test to ensure they meet road safety and environmental standards. The DVSA (Driver and Vehicle Standards Agency) separates these vehicles into different classes depending on their type, size, and purpose. These are known as MOT test classes.

Each class represents a specific category of vehicle. For example, the car you drive daily falls into one class, while a commercial van or motorcycle would be placed into another. As an MOT tester, you’ll need to be qualified to inspect the particular classes of vehicles you intend to work with.

Overview of Common MOT Test Classes

Here is a breakdown of the most common MOT test classes:

• Class 1 and 2: These cover motorcycles, with or without sidecars.
• Class 3: Three-wheeled vehicles that weigh up to 450 kg.
• Class 4: Cars, taxis, private hire vehicles, ambulances, and small vans (up to 3,000 kg).
• Class 5: Private passenger vehicles with 13 or more seats.
• Class 7: Commercial goods vehicles between 3,000 kg and 3,500 kg. 

The most popular MOT test classes for testers are Class 4 and Class 7, as these include the majority of private vehicles and light commercial vans on UK roads. 

Why MOT Test Classes Matter for Your Career

Understanding MOT test classes is crucial because your certification determines what vehicles you are legally allowed to inspect. If you are only certified in Class 4, for example, you cannot conduct MOT tests on Class 7 vehicles until you receive additional training and approval. 

For many testers, starting with Class 4 and 7 is the most practical route because these vehicles are the most commonly tested. Most garages and MOT test centres will want their testers qualified in these classes to meet customer demand. 

You can take an accredited Class 4 and 7 MOT tester training course with MOT Training Experts, a top-rated UK provider offering a 4-day hands-on program tailored for new testers. 

How to Get Certified for MOT Test Classes

To test vehicles under any MOT class, you must be trained and approved by the DVSA. Here’s how to get started: 

1. Meet the Entry Requirements

Before enrolling in an MOT tester course, you need to meet the following criteria:

• Hold a Level 3 qualification in vehicle maintenance and repair.
• Have at least 4 years of experience working on the types of vehicles you want to test.
• Hold a full UK driving licence.
• Pass a DBS (Disclosure and Barring Service) check. 

2. Enrol in an MOT Tester Course

Once you meet the requirements, you can enrol in an MOT tester training course that covers your desired test classes. For most new testers, the Level 2 Award in MOT Testing for Class 4 and 7 is the starting point. 

The course typically lasts four days and includes both classroom learning and practical, hands-on training. You'll learn how to:

• Follow DVSA testing procedures
• Carry out inspections safely and accurately
• Use official testing equipment
• Record results in the MOT Testing Service (MTS) 

MOT Training Experts offers this course with expert trainers and real workshop experience to fully prepare you for DVSA approval. 

3. Complete the DVSA Demonstration Test

After completing your training, you must pass a DVSA demonstration test. This is conducted at your workplace by a DVSA examiner, who will assess your ability to carry out a full MOT test on the vehicles in your chosen class. 

Once you pass, you’ll be added to the official DVSA MOT Tester Register and can begin testing vehicles professionally. 

Expanding into Additional MOT Test Classes

After you’re certified in Class 4 and 7, you may choose to expand your qualifications into other MOT test classes. This could include:

• Class 1 and 2 for motorcycles
• Class 5 for large passenger vehicles 

Expanding your certification can make you more valuable to your employer or allow you to start your own MOT testing service. Many testers add more classes over time as they gain experience and business opportunities. 

Staying Qualified with Annual Training

Once certified, every MOT tester—regardless of which MOT test classes they’re qualified for—must complete MOT annual training and an assessment. This is a DVSA requirement and helps ensure that all testers stay updated on current regulations and testing procedures. 

Failing to complete your annual training by the deadline (31 March each year) may result in suspension or removal from the tester register. 

Benefits of Training in Class 4 and 7 MOT Test Classes

Focusing on Class 4 and 7 offers multiple benefits:

• High demand: These vehicles make up the majority of MOT tests in the UK.
• Better employment opportunities: Most garages want testers certified in these classes.
• Career flexibility: You can work in a wide range of settings—from independent garages to national chains.
• Higher earnings: Being able to test more vehicles means more earning potential. 

Whether you are looking to get started or advance your career, this training path opens the door to steady and well-paying job opportunities. 

Choosing the Right Training Provider

Not all training providers offer the same quality of education and support. When selecting where to train, look for:

• DVSA-approved courses
• Experienced instructors
• Practical, hands-on learning
