Windscreen Repairs for Warrants of Fitness are something most people don’t even consider.

However a WOF issuing agent is within the law to decline a warrant of fitness for any vehicle that has ANY unrepaired windscreen damage.

Most windscreen chips under 50mm anywhere on the windscreen are OK for repair, and some that are much larger can sometimes be repaired.

The chip repair on the left is an example of a chip repair under 50mm (just) that cannot be repaired.

This is because there are actually two separate points of damage.  (The inner crater damage, and the outer half-moon ring.)

The crushed area in the crater is greater than 10mm, and thus this windscreen is unrepairable.
