MOT Rules and Test Requirements

DrivingEngland, Wales & ScotlandLast reviewed: 1 April 20256 min

Most vehicles over 3 years old must pass an annual MOT test to be driven legally on public roads in the UK. Understanding the test categories, costs, and your rights — including what to do if you believe the result is wrong — helps you avoid unnecessary costs and stay road-legal.

Important

This is general guidance only. Road traffic law, DVLA requirements, and penalty notices can change — always check the current GOV.UK guidance or seek legal advice for your specific situation before making decisions.

Key points

  • Cars, motorcycles, and light goods vehicles must have an annual MOT once they are 3 years old.
  • The maximum MOT test fee is £54.85 for cars and £29.65 for motorcycles — garages can charge less.
  • MOT results are categorised as Dangerous (fail, do not drive), Major (fail), Minor (pass with advisory), Advisory (pass), or Pass.
  • If your vehicle fails, you have the right to a free partial retest if it is returned within 10 working days.
  • You can appeal an MOT result to the Driver and Vehicle Standards Agency (DVSA) within 14 working days.

When an MOT is Required

An MOT certificate is legally required for most vehicles over 3 years old that are used on public roads in Great Britain. The rules apply to:

  • Cars, motorcycles, and light goods vehicles (up to 3,000kg)
  • Motor homes and campervans
  • Taxis and private hire vehicles (which require annual testing from the point of first use)

Exemptions from the standard 3-year rule include:

  • Vehicles registered as historic vehicles (pre-1960 and exempt since 2018 for those made before 1 January 1960)
  • Electric bikes and most agricultural vehicles
  • Vehicles with a Statutory Off Road Notification (SORN)

Your MOT expiry date is shown on your V5C logbook, your current MOT certificate, and the MOT history tool at gov.uk/check-mot-history. You can have your MOT done up to a month (minus a day) before the expiry date without losing the remaining time on your current certificate.

MOT Test Result Categories

Since 2018, MOT results are categorised into five grades, replacing the previous pass/fail/advisory system:

  • Dangerous: A significant, immediate risk to road safety or the environment. The vehicle must not be driven until repaired. The vehicle automatically fails.
  • Major: A defect that may affect the vehicle's safety, put others at risk, or have an impact on the environment. The vehicle fails and must be repaired before it can be driven legally.
  • Minor: A defect that has no significant effect on the safety of the vehicle or impact on the environment. The vehicle passes but the defect should be repaired as soon as possible.
  • Advisory: Something that is not currently a defect but could become one. Noted on the certificate for the driver's information.
  • Pass: No defects identified.

If your vehicle receives a Dangerous or Major finding, it fails the MOT. You should not drive it away — arrange collection by a transporter or repair on-site.

MOT Fees and Your Right to a Retest

The government sets a maximum fee that MOT testers can charge. Current (2024) maximum fees:

  • Car: £54.85
  • Motorcycle (up to 200cc): £29.65
  • Motorcycle (over 200cc): £29.65
  • Motor home/campervan (up to 3,000kg): £54.85

Garages can and often do charge less than the maximum. If your vehicle fails, you have the right to a free partial retest on the items that failed if the vehicle is returned to the same garage within 10 working days. If you take the vehicle to a different garage for the retest, or wait longer than 10 working days, you will be charged a full test fee again.

Appealing an MOT Result

If you believe your vehicle was failed incorrectly, you can appeal to the Driver and Vehicle Standards Agency (DVSA):

  1. Contact DVSA within 14 working days of the test (earlier if possible, so the vehicle can be inspected without being repaired first).
  2. DVSA will arrange for the vehicle to be examined at a DVSA vehicle testing station by an independent inspector.
  3. If the appeal is upheld (i.e., the original fail was wrong), you will receive a refund of your MOT fee and any costs incurred by the appeal.
  4. If the appeal is not upheld, you may be charged for the appeal test (currently £54.85).

To start an appeal, call DVSA on 0300 123 9000 or use the online complaint form at gov.uk/complain-about-mot. Note: do not repair the failed items before the appeal inspection or the appeal cannot proceed.

Frequently asked questions

Can I drive my car if my MOT has expired?
No. Driving without a valid MOT is a criminal offence, punishable by a fine of up to £1,000 (it is not an endorsable offence — no penalty points). Your car insurance may also be invalidated, as most policies require the vehicle to be roadworthy and legally compliant. The only exception is driving to a pre-booked MOT appointment.
My car passed but with an advisory — do I have to fix it?
An advisory is not a failure and you are not legally required to fix it immediately. However, advisories indicate items that could fail at the next test or deteriorate into a safety issue. It is good practice to address advisories promptly — and they are useful evidence when selling a vehicle.
Can I drive home from a garage if my car fails the MOT?
If your car fails with only Minor defects, you can drive it away (it has a technical pass). If it fails with a Major defect, you can still drive it to have it repaired elsewhere, but you take the legal and insurance risk of driving an unsafe vehicle. If it has a Dangerous defect, you must not drive it at all — arrange for it to be transported or repaired at the garage.
Will modifications affect my MOT?
Yes. Modifications that affect the vehicle's safety, emissions, or lighting — such as lowered suspension, tinted headlights, or non-standard tyres — may cause an MOT failure if they do not meet the required standards. Always check whether a proposed modification is MOT-compliant before having it fitted. Some modifications also require DVLA notification.
