If your vehicle has failed a Roadworthy Certificate you may want to refer to the following information.
This is general information but an accurate guide as per windscreen repair standards for NSW & QLD. However, please seek advice from your local licensed vehicle test center for detailed information, as some States in Australia may be different.
What can be repaired?
A windscreen should be replaced if it is severely chipped, cracked, abraded, badly scratched or discolored.
The area of the windscreen in front of the driver extending across to the center of the vehicle is only allowed to have any two of the following defects.
- A crack up to 30mm long (Size of a 20c coin)
- A crack from the very edge of the windscreen no more than 75mm long (A fraction longer than the width of $50 note)
- A Bulls eye/star or other windscreen chip no more than 16mm in diameter (Size of a 5c coin)
You should also consider that not all windscreen repairers can or will repair this kind of damage. For example, Service 8® Auto Glass only repairs stone chips, not long cracks.
In our experience we believe that repairing a long crack is not worth the investment for you. When a long windscreen crack is repaired the clarity is only marginally restored, (perhaps 60/70%). This means you can still clearly see the crack in sunlight even when it has been repaired. At night this can be a driver distraction as lights from oncoming traffic can glare as they shine on the crack.
Smaller windscreen stone chips on the other hand can improve in clarity as much as 80%. So repairing a smaller chip has a much better result and much less chance of the glare effect.
Some auto glass repairers will only repair very small chips no larger than 5mm. This is because their equipment has limitations and can struggle to repair chips any larger. This can become a problem if you have a chip of 16mm and you need it fixed for a roadworthy.
Service 8® has professional quality manual windscreen repair systems. This allows our experienced technicians to skillfully work the chip, so we can fix larger chips with more success. Automated machines used by larger corporations are designed for inexperienced trainees with low skill levels. These repair kits have limitations.
