MOT (Ministry of Transport Test)

The UK's annual roadworthiness test, mandatory for cars over three years old. Records mileage and any defects on a public-access history.

Definition

The MOT — short for Ministry of Transport, the government department that introduced it in 1960 — is the United Kingdom's annual roadworthiness inspection. It is mandatory for every car older than three years and tests brakes, lights, tyres, emissions, structural condition, and approximately 90 other items. Each test produces a record stored in the central MOT database, which is publicly accessible by VIN or number-plate at the UK government's free lookup service. The MOT mileage history is one of the highest-integrity used-car data sources in Europe: every reading is logged by a licensed tester, the records are tamper-resistant, and the history extends back roughly two decades for a typical car. The post-Brexit MOT remains unchanged; it does not transfer to or from EU periodic inspection systems.

Why it matters when buying a used car

The UK MOT is the single best dataset for catching rollback on a UK-imported car. A buyer outside the UK should always ask for an MOT history printout when considering a UK import — it is free and definitive.
