MOT Advisories, Minor, Major or Dangerous: Read the Result Before Deciding
An MOT result can contain several kinds of finding on the same page. Before deciding what to repair or whether to sell the car, check the overall result, the category beside each item and the tester’s exact wording. The number of lines on the report is less useful than understanding what those lines mean.
Start with the latest test, not an old certificate
Check the registration, test date and recorded mileage so you know which result you are reading. A previous pass and a later failure can both appear in the history. Read the latest entry and keep any repair invoices or retest result alongside it.
The official GOV.UK MOT-history service shows recorded results and mileage. For tests in England, Scotland and Wales, you can also download certificates and see the recorded defects. If a description is unclear, ask the test centre to explain the item and its location on the car.
Read each category separately
The DVSA inspection manual distinguishes minor, major and dangerous defects. Advisories are separate observations, not another name for minor defects.
- Advisory: an observation the tester wants you to know about, such as deterioration that has not reached the failure threshold. Ask what should be monitored and when it should be checked again.
- Minor: a recorded defect that does not, by itself, cause a failure. It still needs attention; ask the garage what action is appropriate.
- Major: a defect serious enough to cause a failure. It may affect safety, other road users or the environment. Establish the repair required rather than treating it as an advisory.
- Dangerous: the most serious category, including an immediate road-safety risk. The car fails, and you must not drive it until the dangerous defect has been repaired.
GOV.UK’s result guidance confirms that major or dangerous findings cause a failure. A pass can still include minor defects and advisories, so read the detail even when the overall result says “pass”.
Do not use the label alone to decide whether to drive
An unexpired previous MOT is not enough on its own. GOV.UK says you can take a failed vehicle away when its current MOT remains valid and no dangerous problems were listed; it must also meet the minimum roadworthiness standards at all times. Those are separate conditions, not permission to ignore a major defect.
If the report lists a dangerous defect, do not drive the car away. Ask the garage about repair or appropriate vehicle transport. A booked appointment or a short journey is not a reason to drive a dangerous vehicle. If you are uncertain about a fault, resolve the safety question before moving the car.
You remain responsible for the vehicle’s condition. GOV.UK’s roadworthiness guidance expressly warns that a vehicle can be unsafe despite having a current MOT certificate.
Turn the report into questions for the garage
Ask for an explanation and a written estimate that separates the work needed for the failed items from other recommended maintenance. Useful questions include:
- Which finding caused the failure, and what did the tester observe?
- What work is needed to address that finding, and is further investigation required?
- Which other items need attention soon, and which should be monitored?
- Does the estimate include parts, labour and any relevant taxes or additional charges?
- What retest arrangements and deadlines would apply if the work goes ahead?
Do not assume every line represents a separate replacement part, or that a familiar component name means the fault is identical to one you have had before. The severity and wording matter. Ask the garage to distinguish confirmed repairs from work it cannot price until it investigates further.
Retest arrangements depend on the circumstances, including where repairs are done and when the car returns. Check GOV.UK’s retest guidance rather than assuming every retest is free.
Use the result as evidence for your next decision
An MOT category does not tell you the repair bill or decide whether the car should be scrapped. Compare the garage’s findings with the car’s wider condition and your plans for it. Our guide to the options after a failed MOT covers the next decision once the result is understood.
If you request a vehicle quote, share the test date, exact findings and any confirmed repairs. Explain where the car is and whether the garage has identified a movement or access problem. Our garage collection checklist helps prepare the handover without assuming the car can be driven.
