What goes wrong?
The most common MOT failure reasons are the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, the aim of a headlamp is not within limits laid down in the requirements, a lamp missing and inoperative or in the case of a multiple light source more than 1/2 not functioning. The top issue, the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, caused 39 failures in 2024. Checking tread depth (1.6mm legal minimum, 3mm recommended) before your test can save an unnecessary fail. You can check prices at Black Circles if you need replacements. If you need repairs before retesting, sites like BookMyGarage let you compare local prices.
