What goes wrong?
The most common MOT failure reasons are a suspension pin, bush or joint excessively worn, a lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning and a suspension joint dust cover missing or no longer prevents the ingress of dirt etc. The top issue, a suspension pin, bush or joint excessively worn, caused 437 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.
