MOT
What it really means
The annual safety test that every car over three years old must pass to be legal on UK roads. People say "my car is in for its MOT" or "it failed its MOT". Driving without a valid MOT can mean a fine.
Context, tips & common mistakes
The MOT is the annual roadworthiness test required for most cars over three years old in Great Britain — driving without a valid one is illegal, invalidates insurance in practice, and blocks road tax renewal. It is a test, not a service: passing means minimum safety standards, not that the car has been maintained.
The genuinely useful newcomer trick: the full MOT history of any car — passes, failures, advisories, recorded mileage — is free to check on GOV.UK with just the registration plate. Run that check before buying any used car; a mileage that jumps backwards or a string of serious failures tells you more than the seller will. Book tests at approved centres, and note you can be tested up to a month early while keeping your renewal date.
