Lighting and signalling: 18.4% of all tests (5 million)

Suspension: 12% of failures (3.3 million)

Brakes: 9.6% of failures (2.6 million)

Retest after a repair
In some cases, your vehicle can have a partial retest for free or a reduced MOT fee.

Leaving your vehicle for repair
You only need a partial retest if you leave the vehicle at the test centre for repair and it’s retested within 10 working days. There’s no fee for this.

Taking your vehicle away for repairs
You can take your vehicle away if your MOT certificate is still valid.

If your MOT has run out you can take your vehicle to:

1. Have the failed defects fixed
2. A pre-arranged MOT test appointment
3. In both cases, your vehicle still needs to meet the minimum standards of roadworthiness at all times or you can be fined.

Changes to the MOT test came into force on the 20th May 2018. The changes include a number of new defect types and tighter rules for diesel emissions. Here’s an overview:

1. Defects will be categorised in a different way

Defects will be classified as either dangerous, major or minor:

Dangerous defects: A direct and immediate risk to road safety or has a serious impact on the environment. Do not drive the vehicle until it’s been repaired. Overall impact on MOT: Fail

Major defects: It may affect the vehicle’s safety, put other road users at risk or have an impact on the environment. Repair it immediately. Overall impact on MOT: Fail

Minor defects: No significant effect on the safety of the vehicle or impact on the environment. Repair as soon as possible. Overall impact on MOT: Pass

Advisory: It could become more serious in the future. Monitor and repair it if necessary. Overall impact on MOT: Pass

Pass: It meets the minimum legal standard. Make sure it continues to meet the standard. Overall impact on MOT: Pass

2. Changes to the rules for diesel emissions

There are stricter rules for diesel cars with a diesel particulate filter. A major fault will be recorded if smoke is seen to be coming from the exhaust, or if there is evidence that the filter has been tampered with.

3. Additional checks

• If tyres are obviously underinflated
• If brake fluid has been contaminated
