Van Driving Past a Sign at an MOT Test Centre

Each type of vehicle is categorised into one of six MOT classes, designed to help MOT test centres apply the right checks to the right vehicles. After all, a moped has different mechanical requirements than a heavy goods vehicle, right?

If your vehicle’s just turned three (happy birthday) and you need to take it for an MOT, you may be wondering what MOT class it is. Read on to find out:

Class 1

Small motorbikes - up to 200cc or a motorbike and sidecar up to 200cc.

Class 2

Motorbikes (and with sidecars) over 200cc.

Class 3

3-wheeled vehicles that weigh up to 450kg.

Class 4

This includes most road vehicles:

  • Cars (with up to eight passenger seats)
  • 3-wheeled vehicles over 450kg
  • Motor caravans (a.k.a, campers, RVs, or motorhomes)
  • Ambulances and taxis
  • Private passenger vehicles (up to 12 passenger seats)
  • Goods and services vehicles with a gross weight of up to 3,000kg

Class 5

  • Private passenger vehicles and ambulances (13-16 passenger seats)
  • Private passenger vehicles and ambulances (over 16 passenger seats) Playbuses
  • Coaches

Class 7

Goods and services vehicles with a gross weight of between 3,001kg and 3,500kg

Class 4 vehicles with 9-12 passenger seats and Class 5 vehicles with over 13 passenger seats which also require a seatbelt check are classed as a Class 4a or Class 5a, respectively.

The Annual Test

For vehicles over 3,500kg (that’s 3.5 tons), there’s a separate test known as the Annual Test. A test on these vehicles needs to be conducted by an Authorised Test Facility (ATF) or at the DVSA test station. Due to the larger size, the annual test cannot be done at a local repair centre.

Does my vehicle need an MOT?

Your vehicle most likely does. If your vehicle is three years or older, or is an ambulance, taxi, minibus, or playbus over one year old, then you’re legally required to put it through an MOT test once a year. This is in order to check that all vehicles on the road meet a minimum safety level.

Is My Van Class 4 or 7?

These classifications are decided on by gross weight. Which means the maximum laden weight (the total weight the chassis can hold). This is also known as the MAM (maximum authorised mass) or GVW (Gross Vehicle Weight).

A Class 7 van is unlikely to weigh 3.5 tons, but its chassis is usually designed to be able to carry up to 3.5 tons (including the van itself). Usually, you’ll be able to find this information in your vehicle’s manual or often on a sticker by the driver’s door.
