Will a cracked windscreen fail an MOT?

How windscreen damage can affect MOT results, driver visibility and when replacement is safer than repair.

Visibility is the key issue

Damage in the driver's viewing area is treated more seriously because it can affect road safety. Size, position and severity decide whether repair is possible or replacement is needed.

Cracks can spread quickly

Temperature changes, vibration and road impacts can turn a small crack into a larger failure. It is usually cheaper to act early before the glass becomes unsafe.

Repair is not always suitable

Some chips can be repaired, but long cracks, edge damage and damage in critical vision areas often require replacement.
