Failed your roadworthy? The re-inspection window explained
A roadworthy fail is not the end of the world, but the clock starts immediately. Here is how the re-inspection window works in each state and the rules that catch people out.
How the re-inspection window works
If your vehicle fails a roadworthy on one or more items, the inspector issues a written list of defects. You typically have 14 days to rectify those defects and present the vehicle for re-inspection. If you make the deadline and use the same inspector, the re-inspection fee is reduced, often to half the original cost.
If you miss the 14-day window, the inspection lapses. You must start over with a fresh full inspection at full price. The original fee is not refunded.
The 14-day rule is consistent across QLD, NSW, VIC, TAS and ACT. WA, SA and NT do not operate a fixed re-inspection window in the same way because their inspection regimes are event-based rather than annual.
What gets re-checked
Strictly, only the items that were marked as failed need to be re-checked at the re-inspection. The inspector verifies each item is now within standard, signs off the re-inspection, and issues the certificate.
In practice, inspectors will re-check anything that has obviously changed since the original inspection. If your tyres have been replaced as part of the rectification, the inspector will look at the new tyres. If you have welded structural rust, the weld is examined.
What inspectors will not do is re-check items that passed the first time, then fail them at re-inspection on a new fault that was not present originally. The re-inspection scope is bounded by the original fail list.
Use the same inspector if you can
Re-inspection rules apply only when you return to the same inspector who did the original failed inspection. If you go to a different inspector with the original fail report, that second inspector will charge a full new fee, they are starting from scratch.
This is a strong reason to choose a mobile inspector you trust the first time. A good operator will rebook you within the 14-day window at the discounted re-inspection rate. They will often also tell you straight which workshop to use for the rectification, which avoids further delay.
When 14 days is not enough
Major rectifications, structural rust repair, gearbox issues that surface during the road test, accident-damage repairs identified on inspection, can take longer than 14 days because of parts lead times. If you cannot meet the deadline, you have two options:
1. Let the inspection lapse and book fresh. Annoying and more expensive, but it gives you the time you need. There is no penalty beyond the second full fee.
2. Apply for an extension. A few states allow this in genuine cases (parts on backorder, supply chain delays). It is rare, requires written application, and is rarely retroactive, apply before the 14 days expire.
Plan ahead: if you suspect a major fail before booking, get the worst-case repair done first, then book the inspection. A clean inspection with no fails is always cheaper than a fail-rectify-re-inspect sequence.
