MOT Classes Explained: Which MOT Test Does Your Vehicle Need?

Why MOT Classes Exist

The MOT test has been a legal requirement for most UK vehicles since 1960, and in the decades since, the range of vehicles on British roads has grown enormously. A 50cc scooter and a 3.5-tonne panel van share the same tarmac, but they have entirely different mechanical systems, weight distributions, safety risks, and testing requirements. Applying one identical test to every vehicle would either fail to scrutinise the right things or create an unworkable inspection process.

The Driver and Vehicle Standards Agency (DVSA) uses a classification system to solve that problem. Each class groups vehicles by type, weight, engine size, or passenger capacity, and assigns testing requirements appropriate to those characteristics. The class your vehicle falls into determines what gets checked, how long the test takes, what equipment the garage needs, and in some cases, how frequently the test is due.

There are more than 23,500 DVSA-authorised test stations across England, Scotland and Wales, employing over 65,800 qualified testers. However, not every station is authorised for every class. A garage that tests Class 4 cars all day may not have the specialist bay or trained examiner needed for a Class 7 van, or the appropriate equipment for a Class 5 minibus. Knowing your class before you book is not a bureaucratic formality. It is the first step to a smooth, stress-free test.

MOT Classes at a Glance

Before diving into each class in detail, here is the full picture in one place.

Class	Vehicle Type	Key Threshold	First MOT Due
Class 1	Mopeds and small motorcycles	Up to 200cc engine	3 years
Class 2	Larger motorcycles	Over 200cc engine	3 years
Class 3	Three-wheeled vehicles	Up to 450kg unladen	3 years
Class 4	Cars, taxis, vans, motorhomes	Up to 3,000kg DGW, up to 8 seats	3 years (1 year for taxis)
Class 4a	Minibuses with additional seatbelts	9 to 12 seats	3 years
Class 5	Large passenger vehicles	13 or more seats	1 year
Class 5a	Large passenger vehicles with extra belts	13 or more seats	1 year
Class 7	Heavy light commercial vehicles	3,001 to 3,500kg DGW	3 years

Each of these classes is explained in full below. If you already know your vehicle type, you can jump straight to the relevant section.

Class 1 and Class 2: Motorcycles, Mopeds and Sidecars

For two-wheeled vehicles, the dividing line is engine size, not the style of bike or the number of riders. The DVSA draws a clean cut at 200cc, and everything either falls below it or above it.

Class 1: Mopeds and Small-Engine Motorcycles

Class 1 covers motorcycles and mopeds with an engine capacity up to 200cc. This includes 50cc scooters, 125cc learner bikes, Vespas, and any small-engine two-wheeled vehicle with a sidecar, provided the engine stays within that threshold. The first MOT is due three years after the date of first registration, and annually from that point.

The test for Class 1 vehicles covers the safety-critical systems specific to two-wheeled transport, including the following.

Brakes and brake performance, steering and handlebars, tyres and wheels including tread depth across the central three quarters of the tyre, lights and reflectors, frame and structural condition, fuel system and exhaust.

Riders in North Camp and Ash Vale who use smaller motorcycles or scooters for their daily commute should confirm that their chosen test centre holds Class 1 authorisation before booking, as not all garages that test cars are set up for motorcycles.

Class 2: Larger Motorcycles and High-Power Bikes

Class 2 applies to any motorcycle or moped with an engine capacity over 200cc, with or without a sidecar. Sports bikes, touring motorcycles, cruisers, and large-engine commuters all fall here. The same three-year first test rule applies, and the inspection covers the same core categories as Class 1 but accounts for the additional components that come with higher-powered machines, including more complex brake systems, larger fuel assemblies, and the additional structural demands of carrying greater engine weight.

Riders commuting between Aldershot and Farnborough on 600cc or larger motorcycles are Class 2, regardless of whether their bike has a sidecar attached.

Class 3: Three-Wheeled Vehicles

Class 3 is one of the least common MOT categories on UK roads, but it exists for a specific and important reason. Three-wheeled vehicles have a distinct handling profile, a different centre of gravity, and unique structural considerations that set them apart from both motorcycles and conventional four-wheeled cars.

Class 3 applies to three-wheelers with an unladen weight of up to 450kg. The unladen weight, not the engine size, is the determining factor here. Motorcycle-and-sidecar combinations are excluded from Class 3, they fall into Class 1 or Class 2 depending on engine size. Classic three-wheeled cars and some modern electric three-wheelers fall into Class 3.

One important detail: if a three-wheeled vehicle weighs more than 450kg unladen, it moves up into Class 4 rather than staying in Class 3. This is a genuine source of confusion for owners of heavier trike-style vehicles, so checking the unladen weight in the V5C logbook before booking is essential.

Class 4: The MOT Test Most UK Drivers Will Ever Need

Class 4 is the backbone of the UK MOT system. It is the test that the overwhelming majority of drivers will encounter every year without ever having to think about it, because their vehicle falls so comfortably within its boundaries.

Class 4 covers a broader range of vehicles than most people realise.

Standard passenger cars with up to eight seats, taxis and private hire vehicles (tested annually from one year after registration rather than three), ambulances with up to twelve passenger seats, dual purpose vehicles such as Land Rovers and similar four-by-four utility vehicles, motor caravans and campervans, light goods vehicles with a Design Gross Weight (DGW) of up to 3,000kg, and three-wheeled vehicles weighing more than 450kg unladen.

If you drive a standard car anywhere across the Aldershot, Farnborough, or Fleet area, your vehicle is almost certainly Class 4. The same applies to most motorhomes under 3,000kg and the majority of smaller vans used for personal or light business purposes.

What Does a Class 4 MOT Actually Check?

The Class 4 inspection is a thorough assessment of the safety-critical systems on your vehicle. It does not check the general mechanical condition or engine health in the way a full service does, but it does cover everything that directly affects road safety and environmental compliance.

According to DVSA data for Q3 of the 2024 to 2025 testing year, the most common failure categories for Class 3 and 4 vehicles were as follows.

Most Common Class 4 Failure Categories (Q3 2024/25)

Defect Category	Percentage of Tests
Lamps, reflectors and electrical equipment	10.60%
Brakes	9.03%
Body, chassis and structure	4.46%
Noise, emissions and leaks	3.24%

Lights and brakes account for the two largest failure categories by a significant margin. A quick walk-around check before your test, checking every light including number plate lights and brake lights, and making sure your wipers clear the screen properly, can prevent the most avoidable failures.

Class 4a: When Additional Seatbelts Change the Picture

Class 4a is a variation of Class 4 that most drivers will never encounter, but it matters if you operate a vehicle with nine to twelve passenger seats that carries more seatbelts than the regulatory minimum requires. In these cases, the standard Class 4 test is extended by a specific seatbelt installation check, confirming that the additional belts have been correctly fitted and meet the required safety standard.

The maximum DVSA fee for Class 4a is the same as for Class 4. The test covers everything in a standard Class 4 inspection plus that seatbelt verification. Private hire operators running larger vehicles in Camberley or Woking should confirm with their garage whether their vehicle falls into Class 4 or Class 4a before booking.

Class 5: Large Passenger Vehicles

Class 5 exists because transporting thirteen or more people in a single vehicle carries a fundamentally different level of responsibility than driving a family car. The safety standards are more stringent, the structural checks are more detailed, and the testing frequency is higher.

Class 5 covers private passenger vehicles, ambulances, motor caravans (in specific configurations), and dual purpose vehicles with thirteen or more passenger seats. This includes minibuses, large coaches, and some converted vehicles used for group or community transport.

There are two important differences between Class 5 and Class 4.

First test timing. Unlike Class 4 vehicles, which have their first MOT in three years, Class 5 vehicles are required to be tested from just one year after first registration. The logic here is straightforward, vehicles carrying large numbers of passengers face more intensive use and need more frequent scrutiny.

Testing availability. Class 5 is a specialist test. Far fewer garages across the UK hold Class 5 authorisation compared to Class 4. If you operate a minibus in Guildford or Godalming, it is worth ringing ahead to confirm that your chosen test centre is equipped and authorised before making the trip.

Class 5a: The Seatbelt Addition

Class 5a mirrors the relationship between Class 4 and Class 4a. Where a Class 5 vehicle carries more seatbelts than the minimum requirement, and those additional belts have not previously been subject to a type-approved installation check, the test is classified as Class 5a. The extra element is a formal seatbelt installation inspection layered on top of the standard Class 5 test.

Operators of adapted or converted large passenger vehicles, including community transport providers and some school transport operators, should clarify with the DVSA or their garage whether their vehicle requires a Class 5 or Class 5a test before booking.

Class 7: The Test That Catches Van Drivers Off Guard

More drivers are caught out by Class 7 than any other category. On the surface, a large Transit-style van looks like it should be a Class 4 vehicle. It goes to the same roads, sits in the same traffic, parks in the same spaces. But if its Design Gross Weight exceeds 3,000kg, it crosses into Class 7 territory, and that changes everything about how and where it can be tested.

Class 7 covers goods vehicles with a DGW between 3,001kg and 3,500kg. This bracket captures a significant number of popular commercial vehicles used by tradespeople, delivery drivers, and small business owners across the UK.

Common vehicles that often fall into Class 7, depending on their specific payload specification, include larger panel vans, certain high-roof and long-wheelbase variants of popular commercial ranges, and some pickup trucks with substantial payload ratings. The same model in a lighter specification may be Class 4, which is exactly why checking the DGW on your V5C is essential rather than assuming based on the vehicle name alone.

Class 4 vs Class 7: The Key Differences

Feature	Class 4	Class 7
Design Gross Weight	Up to 3,000kg	3,001 to 3,500kg
Typical vehicles	Cars, small vans, motorhomes	Larger vans, pickups, light trucks
First MOT due	3 years	3 years
Specialist bay required	No	Yes
Available at all garages	Most authorised centres	Specialist centres only

Class 7 testing requires specialist equipment and examiners specifically trained for heavier light commercial vehicles. If you arrive at a standard car test centre with a Class 7 van, there is a real chance the garage will be unable to test you that day. Tradespeople in Farnham, Tongham, and North Camp who rely on larger vans for their work should always call ahead to confirm Class 7 availability.

How to Tell Whether Your Van Is Class 4 or Class 7

This is the question that matters most for van drivers, and the answer is simpler than most people expect.

Open your V5C logbook and look for the gross vehicle weight or Design Gross Weight figure. If it reads 3,000kg or below, your van is Class 4. If it reads anything from 3,001kg to 3,500kg, it is Class 7.
Check the manufacturer’s plate on the vehicle itself. On most vans, this is found inside the driver’s door frame. It will show the gross vehicle weight alongside other key figures.
If neither of those options gives you a clear answer, call your local DVSA-authorised garage. Any approved test centre will be able to confirm your class from the make, model, year, and variant of your vehicle.

Do not rely on the size or appearance of the van to make this call. Two vans of the same model and body style can fall on opposite sides of the Class 4 and Class 7 line based purely on payload specification.

What About Class 6?

Class 6 is the category that does not appear in a standard MOT booking system, and there is a simple reason for that. It exists, but it is not available at regular garages.

Class 6 is the Public Service Vehicle (PSV) test, covering vehicles used for hire or reward with more than eight passenger seats. This test is conducted exclusively by DVSA staff at their own testing stations or at DVSA-authorised testing facilities and designated premises. It is not something a private driver or business owner books through a local garage.

If you are reading this guide to understand which class to select when booking an MOT, Class 6 is not your answer. It is a specialist regulatory test that operates entirely outside the standard MOT network. The absence of Class 6 from most booking systems is intentional, not an error.

How to Find Out Which MOT Class Your Vehicle Is

If you have read through the sections above and you are still unsure where your vehicle sits, here is a three-step process that will give you a definitive answer.

Step 1: Check Your V5C Logbook

The V5C, also known as the log book, is the most reliable starting point. For cars and vans, look for the gross vehicle weight or Design Gross Weight (DGW) figure. This single number tells you whether you are in Class 4 territory (up to 3,000kg) or Class 7 (3,001 to 3,500kg). For motorcycles, look for the engine capacity in cubic centimetres, which tells you whether you are Class 1 (up to 200cc) or Class 2 (over 200cc).

Step 2: Check the Manufacturer’s Plate

Most vehicles carry a manufacturer’s plate that displays key specification data. On vans, it is typically found inside the driver’s door frame or on the door pillar. On motorcycles, it is usually stamped on the frame or near the engine. This plate will confirm the gross vehicle weight and any other class-determining specifications.

Step 3: Call Your Garage Before You Book

Any DVSA-authorised test centre can confirm your vehicle’s class when you call to book. Give them your make, model, year, and variant (particularly important for vans), and they will be able to tell you which class applies and whether they are authorised to carry out that test. This one phone call can save you a wasted journey.

Drivers in Ash Vale, Camberley, and Woking who are unsure about their class are always welcome to call ahead rather than guess.

What Happens If You Book the Wrong MOT Class?

This is the question most guides skip over, but it is arguably the most practically important one in the article.

Two scenarios play out when a vehicle is booked under the wrong class.

Scenario 1: The Garage Cannot Test Your Vehicle

This is the most common outcome. You arrive with a Class 7 van at a garage that only holds Class 4 authorisation. The bay is too small, the equipment is not rated for your vehicle’s weight, and the tester is not qualified for your class. The result is a wasted trip, a vehicle that is still untest and potentially overdue, and the delay of rebooking at a suitably equipped centre.

Scenario 2: The Test Is Carried Out Under the Wrong Class

In some cases, a test may proceed even though the wrong class has been selected. A test certificate issued under the wrong class for your vehicle type may not represent a legally valid MOT. This is a less visible problem but a more serious one, particularly if your vehicle is stopped for a roadside check or if questions arise following an incident.

Both scenarios are entirely preventable. The fix is a single phone call before booking to confirm your class and the garage’s authorisation.

If you are unsure whether your vehicle is fully prepared for its test, it is worth reading up on what to check before your MOT so you arrive in the best possible condition regardless of your class.

DVSA Maximum MOT Fees by Class

The DVSA sets legally binding maximum fees for each MOT class. Garages are not permitted to charge above these figures for the test itself, though they are free to charge less. Additional work carried out as part of repairs following a failure is priced separately and is not subject to the cap.

The current maximum fees are as follows.

MOT Class	Vehicle Type	Maximum Fee (DVSA, 2025)
Class 1	Mopeds and motorcycles up to 200cc	£29.65
Class 2	Motorcycles over 200cc	£37.80
Class 3	Three-wheeled vehicles	£37.80
Class 4 and 4a	Cars, taxis, vans up to 3,000kg	£54.85
Class 5 and 5a	Vehicles with 13 or more seats	£54.85
Class 7	Vans with DGW of 3,001 to 3,500kg	£58.60

For the official and most up-to-date fee schedule, refer to the DVSA MOT fees page on GOV.UK.

These fees have remained unchanged since April 2010, which means that in real terms, the cost of an MOT test has fallen considerably relative to the general cost of living. Most garages operate at or below the maximum, particularly in competitive local markets.

When Is Your First MOT Due?

The first MOT date varies depending on your vehicle class, and this catches a surprising number of drivers out, particularly those who have purchased a used vehicle and are unsure of the testing history.

For most vehicles, the rules are straightforward.

Class 1, 2, 3, 4, and 7 vehicles all have their first MOT due three years after the date of first registration. From that point, the test is annual.

Class 5 and 5a vehicles, those with thirteen or more passenger seats, are required to be tested from one year after first registration. The increased frequency reflects the safety responsibility of high-capacity passenger transport.

Taxis and private hire vehicles, which fall within Class 4, are also tested from one year rather than three, due to the intensity of their daily use.

One useful piece of flexibility: you can book your MOT up to one calendar month minus one day before your current expiry date without losing your anniversary date. The new certificate will run from your original renewal date rather than the test date, effectively giving you up to thirteen months of coverage from a single test. For a full breakdown of how the first test date works across different vehicle types, the guide to when your car needs its first MOT covers this in detail.

The Right Class Makes the Whole Process Simpler

Knowing your MOT class before you pick up the phone is the single most practical thing you can do to make your annual test straightforward. It takes the guesswork out of booking, ensures you arrive at a garage that is actually equipped for your vehicle, and means your certificate is legally valid when it is issued.

For the vast majority of drivers across Aldershot, Farnborough, Fleet, Farnham, Ash, Ash Vale, Tongham, North Camp, Guildford, Camberley, Woking, and Godalming, the answer is Class 4. Your standard car, smaller van, or motorhome under 3,000kg fits comfortably into the most common and widely available test in the UK.

If you ride a motorcycle, your class is determined by your engine size. If you drive a larger van, your DGW in the V5C tells you everything you need to know. If you own a classic that has just crossed the 40-year mark, the exemption rules are clear, provided no substantial changes have been made.

Whatever your vehicle, the right test at the right garage, booked with confidence, is always a better outcome than arriving unprepared. Check your V5C, confirm your class, and book with an authorised centre you trust.

Frequently Asked Questions

What is the most common MOT class in the UK?

Class 4 is by far the most common. It covers standard passenger cars, taxis, dual purpose vehicles, motorhomes, ambulances with up to twelve seats, and light goods vehicles up to 3,000kg DGW. The overwhelming majority of MOT tests conducted across England, Scotland and Wales each year are Class 4.

What is the difference between a Class 4 and a Class 7 MOT?

Both tests cover brakes, lights, tyres, emissions, steering, and structure. The difference is the vehicle. Class 4 applies to vehicles with a DGW up to 3,000kg. Class 7 covers heavier light commercial vehicles with a DGW between 3,001kg and 3,500kg. Class 7 requires specialist bays and trained examiners, and not every garage can offer it.

Is my van a Class 4 or Class 7?

Check the Design Gross Weight in your V5C logbook. Up to 3,000kg is Class 4. Between 3,001kg and 3,500kg is Class 7. Some popular van models sit on either side of that line depending on their payload specification, so always check the specific figure for your vehicle rather than assuming based on the model name.

Is my motorcycle Class 1 or Class 2?

Engine size is the only factor. Up to 200cc is Class 1. Over 200cc is Class 2. This applies whether your bike has a sidecar or not.

Is there a Class 6 MOT?

Class 6 exists as the Public Service Vehicle test but is not available through standard garages. It is conducted exclusively by DVSA staff at designated testing facilities. If you are booking a standard MOT, Class 6 is not applicable.

What is a Class 5 MOT?

Class 5 covers vehicles with thirteen or more passenger seats, including minibuses, large ambulances, and motor caravans with that seating capacity. Class 5 vehicles are tested from one year after first registration and require a garage with specific Class 5 authorisation.

When is my vehicle’s first MOT due?

For Class 1, 2, 3, 4, and 7 vehicles, the first MOT is due three years after the date of first registration. For Class 5 and 5a vehicles, and for taxis and ambulances within Class 4, the first test is due one year after registration.

Is my classic car exempt from the MOT?

Vehicles first registered more than 40 years ago may be exempt, provided they have not been substantially changed in the last 30 years. Exemption is not automatic. You must declare it using a V112 form when taxing the vehicle. Even with exemption, the vehicle must remain roadworthy.

What happens if I book the wrong MOT class?

Either the garage will be unable to test your vehicle due to lack of equipment or authorisation, or the test may be carried out but under an incorrect class, which could affect its legal validity. Always confirm your class with the garage before booking.

Can I book my MOT early without losing my renewal date?

Yes. You can book your test up to one calendar month minus one day before your current expiry date. Your new certificate will run from your original renewal date rather than the date of the test, giving you up to thirteen months of coverage from a single test.

How do I find out my MOT class?

Check the gross vehicle weight or engine size in your V5C logbook, look at the manufacturer’s plate on the vehicle, or call your local DVSA-authorised garage. They will confirm your class from your make, model, year, and variant.
