Will a windscreen chip fail a safety certificate in Queensland?
It can: a chip or crack in the area the driver looks through can fail a Queensland safety certificate, and the final call is the inspector's, so the cheap move is to fix the chip before the inspection.
When you need a safety certificate
In Queensland a private car does not have regular inspections. You need a safety certificate when you sell a registered car, and when you register one that was not registered. It is issued by an Approved Inspection Station, and some of them are mobile.
What inspection stations say they look at
Inspection station guides published in Queensland describe the main viewing area as the part of the windscreen the wiper sweeps in front of the driver. Damage there is what gets looked at most closely. Those guides mention chips of more than about 16 mm and cracks longer than about 150 mm in that area, damage that goes through both layers of the glass anywhere, and any damage with an edge that catches the wiper blades.
Those figures come from inspection station guides, not from the code itself, so treat them as a guide. The inspector makes the call on the day, and the Department of Transport and Main Roads has the final word.
Why fixing the chip first is cheaper
A chip repair is a small fixed price and takes about 40 minutes. A new windscreen costs far more and takes longer to organise. If you are selling, get a fixed price in three taps and get it done before the inspection.
A repair fills the break but usually leaves a faint mark, so nobody can promise that a repaired chip passes: that is the inspector's decision.
If the damage is a crack
A long crack usually means a new windscreen. Send a photo and I will tell you honestly whether it is a repair at all, and point you to someone who replaces glass if it is not.
Selling privately: a short checklist
Walk round the car before you book the inspection. Look at the windscreen from the driver's seat, in the area the wiper sweeps: any chip there is worth fixing first. Run the wipers and check they clear the glass without catching on anything. Look along the edges of the windscreen for chips or cracks that start at the frame.
Then check the things that commonly come up on any inspection, like tyres, lights and wiper blades. Fixing a chip and replacing worn blades costs far less than a second inspection.
Damage that is not a chip
A chip is not the only windscreen problem an inspector can look at. Scratches in the driver's view from worn wiper blades, cloudy patches, and anything stuck to the glass in the line of sight can all be raised. Worn blades are cheap to replace, and I can fit new ones in the same visit as a chip repair.
Mobile inspections
Some Approved Inspection Stations come to you. If you book one, book the chip repair a few days before, so the repair is done and cured well before the inspection.
If you are buying a car
A safety certificate is the seller's job, but a chip is worth noticing when you buy. A chip in the driver's view that was not on the certificate photos, or a chip that has started to run, is something to raise before you pay. A repair is a small fixed price if it is caught early, and a new windscreen is not.
Ask the seller when the certificate was issued and look at the windscreen yourself in daylight, from the driver's seat, with the wipers running.
Questions
Do I need a safety certificate every year?
Not for a private car in Queensland. It is needed when you sell a registered car, or register one that was not registered.
Will a repaired chip pass?
Nobody can promise that. A repair fills the break and usually leaves a faint mark; the inspector decides what passes.
Who issues safety certificates?
Approved Inspection Stations licensed by the Department of Transport and Main Roads. Some of them come to you.
