Class 4 and Class 7 MOT explained: cars and vans

Class 4 is the MOT class for most cars and for goods vehicles up to 3,000 kg design gross weight. Class 7 is for goods vehicles over 3,000 kg and up to 3,500 kg design gross weight, which includes larger panel vans and some pick-up trucks.

The weight that matters is not what is in the load area on the day. It is the design gross weight set by the manufacturer. Here we explain how to find yours and what is different between the two classes. Automaster, at Longcombe Cross near Totnes, tests both classes.

What does a Class 4 MOT cover?

Class 4 is the category most drivers will meet. It covers ordinary passenger cars with up to eight passenger seats, and goods vehicles such as small vans up to 3,000 kg design gross weight. It also covers a number of other vehicle types, such as motor caravans and dual-purpose vehicles, so if you are unsure, check the logbook or ask us.

The test follows the same inspection of lights, brakes, steering, suspension, tyres, seatbelts, body structure and emissions that applies to a family car.

What is a Class 7 MOT and which vans need it?

Class 7 applies to goods vehicles with a design gross weight over 3,000 kg and up to 3,500 kg. In practice that means many larger panel vans and some heavier pick-up trucks. The tests are broadly the same in what they look at, but the vehicle is larger and heavier, so the equipment and the way it is tested differ.

Brake testing is carried out on equipment suitable for the weight of the vehicle, and the garage needs to be set up for Class 7 testing. We test both Class 4 and Class 7 vehicles, but if you have a heavy van, tell us at booking so we can plan for it.

How do I know whether my van is Class 4 or Class 7?

Look for the design gross weight, sometimes called the maximum authorised mass or gross vehicle weight. It is normally on the plate fitted to the vehicle, in the V5C registration document or in the handbook. Do not confuse it with the kerb weight, which is the weight of the empty vehicle.

If your van shows a design gross weight of 3,000 kg or less, it is Class 4. If it shows over 3,000 kg and up to 3,500 kg, it is Class 7. If the figures are not clear, ask us when you contact us for a quote and we can check before you book.

• Find the weight plate or the V5C
• Look for design gross weight, not kerb weight
• Up to 3,000 kg is Class 4
• Over 3,000 kg and up to 3,500 kg is Class 7

Are the MOT tests and rules different for vans?

The yearly timing is the same. A van needs its first MOT on the third anniversary of registration for most vehicles, and then annually. The same defect categories of dangerous, major and minor apply.

Vans often work hard, so common problem areas include tyres that are worn from carrying loads, brakes under strain, and suspension that has deteriorated. Seatbelts and load-area bulkheads or fittings may also be examined. If your van is used for work, plan the MOT early so you are not left without it.

Where can I get a Class 4 or Class 7 MOT near Totnes?

Our garage at Longcombe Cross near Totnes carries out MOT testing for cars and vans. You can ask for a quote by telling us the make, model and registration, whether it is a car or a van, and if it is a van, its design gross weight if you know it.

If the test finds problems, we can discuss repairs with you and carry out the work. We would not promise a repair without inspecting the vehicle first.
