Common MOT failure categories
What goes wrong?
The most common MOT failure reasons are the aim of a headlamp is not within limits laid down in the requirements, a lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning and brakes imbalance across an axle such that the braking effort from any wheel is less than 70% of the maximum effort recorded from the other wheel on the same axle.. The top issue, the aim of a headlamp is not within limits laid down in the requirements, caused 13 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.
