Department of Transport inspections
We're a Department of Transport Authorised Inspection Station — get your vehicle registered or back on the road
Speedy Spanners Mechanics is an authorised inspection station for the Department of Transport. We can also do a pre-DOT inspection for $150 — it helps identify potential issues before the official check, so you avoid unexpected delays.
If a vehicle fails an inspection, the faults identified must be fixed before it can be presented for re-inspection. When booking a re-inspection, give us the inspection reference number from your initial inspection receipt.
