What goes wrong?
The most common MOT failure reasons are a tyre seriously damaged, wiper blade missing or obviously not clearing the windscreen and tyre tread depth not in accordance with the requirements. The top issue, a tyre seriously damaged, caused 1,417 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.
