How long does a blue slip last?
Service NSW lists a 42-day validity period. Plan the remaining registration steps around the report date.
Keep the paper report
Note the inspection date and keep the original hard copy somewhere you can find it. Service NSW asks for it when you register at a service centre, even when the examiner sends the result electronically.
Prepare the rest of the application early
Check what identity, ownership, insurance and plate details you need for the registration appointment. If one document will take longer to obtain, factor that into the timing of the inspection.
If the report has expired
Check with the workshop or Service NSW before travelling. Ask whether another inspection is needed and recheck the rules for moving the vehicle while registration is pending.
