Key takeaways
- A blue slip is a certificate from a mechanic confirming that an unregistered vehicle meets safety, design, and identity standards.
- The cost of a blue slip varies by vehicle type (e.g., $80 for light vehicles, $49 for motorcycles) and is separate from registration and pink slip fees.
- A blue slip is needed if a vehicle's registration has expired for more than three months, if it's from interstate or overseas, or if significant changes have been made to the vehicle.
What is a blue slip?
A blue slip is a letter from your mechanic stating that an unregistered vehicle is safe, and that it meets design and identity standards. Your vehicle will need to pass various tests before you can receive a blue slip, and you won't be able to register an unregistered vehicle without one.
How much do blue slips cost?
The cost of a blue slip will depend on the type of vehicle and is separate to pink slip and registration fees. We got these costs from the Roads and Maritime Services (RMS) website. Costs are for NSW only.
| Type of vehicle | Cost |
|---|---|
| Light vehicle | $80 |
| Motorcycle | $49 |
| Trailer without brakes | $41 |
| Trailer with brakes | $58 |

Blue slip requirements
A blue slip involves an inspection of your car's tyres, lights, fluids, suspension, seatbelts, brakes and checks for any leaks. A similar inspection is done for pink slips, but a blue slip inspection is more thorough. It also involves an identity check which ensures that the vehicle or its parts are not stolen. Your vehicle must also be up to its manufacturer's standards. You can find this in your vehicle's guide, or if none was provided, by a simple search of your vehicle's make and model on the Internet.
Blue slip checklist
If you're taking your unregistered vehicle in for a blue slip inspection, you'll need to take along a few things.
You will also need to make sure your vehicle is in a roadworthy condition and make any necessary repairs before it can pass inspection.
When do you need a blue slip?
You will need to get a blue slip if your vehicle's registration has been expired for more than three months, or if it was brought into New South Wales from interstate or overseas. While these are the most common reasons, you will also need a blue slip if your vehicle:
- Has no number plates
- Was previously written off
- Requires adjustments in its registration records because something about the vehicle has changed significantly, such as a new engine
- Needs defect notices cleared
How long does a blue slip last?
Once your vehicle has passed inspection and you have been issued a blue slip, you have 42 days to use it to register your vehicle. If you don't get your vehicle registered during this time you will need to take your car in for another blue slip inspection.
How hard is it to get a blue slip?
Compared to a pink slip, blue slip inspections are far more rigorous and come at a higher cost (pink slips are generally around $45). Blue slips require more thorough safety and operation checks, and check identification numbers on the vehicle and its parts, such as the engine number, to make sure that nothing has been reported stolen. If a check comes back with evidence of stolen parts, the police may investigate and you will need to supply proof that you bought the vehicle or its stolen part/s legally.
How to get a blue slip for a motorcycle
Getting a blue slip for a motorcycle is similar to getting one for a car. A thorough check is conducted by your mechanic, though it is a simpler inspection as a bike has fewer features to check than a car. Make sure you have completed all necessary repairs to make your motorcycle roadworthy and have your paperwork ready for inspection and registration.
How to get a blue slip for a trailer
Like a motorcycle, trailers are slightly easier to get passed for blue slip inspections. During an inspection, your mechanic will check your wheel bearings, winch and tyres, so be sure they are all in good working order before going in.

I am purchasing a QLD registered car and will be registering it in NSW. The car has had previous NSW registration, do I still need a blue slip?
Hi Kat,
Yes, a Blue Slip is required for unregistered vehicles or those being transferred into NSW, such as your car being transferred in from Queensland. This is because the NSW government wants to ensure the vehicle is roadworthy before it can be registered. Hope this helps!
