What the MOT tests show

What we know

2.1 fails per 100 MOT tests at 17 years, against 7.1 for all class 4 vehicles tested at 17 (all test years). That is about average.

Why it matters

A windscreen, wipers and mirrors fail stops the car passing until it is fixed; the most common one is rated major by DVSA.

What to check

Check the windscreen for chips or cracks in front of the driver, run the wipers and washers, and make sure both door mirrors are intact and adjust.
