Home/Trailer Services/Pre-Rego Inspection Sydney

Pre-rego mechanical inspection for trailers.

Sydney trailer owners book us before they go to a pink slip station. We do the mechanical inspection and fix the things that would fail, so when you take the trailer to an authorised eSafety station, it passes first time.

What this is not. We are not an Authorised Inspection Scheme (AIS) station and we do not issue eSafety Check reports. Pink slip renewal requires a separate visit to an authorised Service NSW inspection station. What we do is the mechanical work before you go, so your trailer is ready to pass when it gets there.

The problem we solve.

In NSW, any trailer over 250kg ATM and more than 2 years old needs an annual eSafety Check (the pink slip) before you can renew its registration. The inspection happens at an Authorised Inspection Scheme (AIS) station. If the trailer fails, you pay the inspection fee, leave with a list of things to fix, fix them, then come back and pay again to be re-inspected.

For most owners, the practical issue is two-fold. First, AIS stations charge a fee whether you pass or fail. Second, the only way to know if you will fail is to take the trailer there and find out. If you have a trailer that has not been serviced in a few years, the odds of failing first time are high.

How we help.

We come to your trailer, mechanically inspect everything an AIS inspector will check, and fix what would fail on the day. You then take the trailer to a pink slip station with confidence it will pass, paying the inspection fee only once.

The inspection scope is the same as the eSafety Check. We just cannot issue the certificate because we are not AIS-accredited (and a mobile operator cannot be, under the current Service NSW framework).

What we check.

Pricing.

Service
From
Pre-rego inspection (single-axle, includes first 2 hours)
$180
Pre-rego inspection (dual-axle, includes first 2 hours)
$280
Common fixes within the same visit (LED globe replacement, plug repair, wiring repairs, tyre swap with customer-supplied spare)
Included up to 1 hour

Major work beyond the included time (full brake jobs, bearing replacement, significant electrical repair) is quoted on the spot before proceeding. Most trailers need at most $100-$300 of additional work to pass pink slip first time.

Common things that fail pink slip inspections.

In rough order of how often we see them:

  1. Light failures. A single failed indicator, brake light, or tail light is enough to fail the inspection. Often a $5 LED globe.
  2. Worn tyres. Either below the legal tread depth (1.5mm), or visibly aged with cracking sidewalls. Tyres over 7 years old are commonly failed even if they look fine.
  3. Brake controller signal absent. The inspector connects a brake controller to the trailer plug and tests the signal reaches the brakes. A failed magnet or broken wire shows up here.
  4. Loose wheel nuts. Often discovered when the inspector tries to remove a wheel and finds them either over-tight (someone used an impact gun wrong) or under-tight (someone forgot to torque after a tyre change).
  5. Brake shoe wear. Found when the inspector pulls a wheel. Common on older trailers that have not had brake work in years.
  6. Number plate light not working. One of the most-missed checks because the owner never sees that light.
  7. Safety chain attachment. Either the chains are missing, the D-shackles are not rated, or the chains are attached in a way that would prevent them functioning if the coupling failed.
  8. Trailer plate missing or illegible. Some older trailers have lost their compliance plate to corrosion. Without it, the inspector cannot verify the ATM rating, which is a fail.
  9. Reflectors missing. Side and rear reflectors are mandatory. They fall off and most owners do not notice.
  10. Excessive rust on chassis. Surface rust is fine. Structural rust (you can poke a screwdriver through it) is a fail.

How long does the inspection take?

About 90 minutes to 2 hours for a single-axle trailer in good condition. Up to half a day for a dual-axle or anything that turns up needing fixes (you want us to fix the things we find, not just list them). For neglected trailers, we might recommend a second visit if major brake or bearing work is needed.

What to do after we leave.

Take the trailer to any AIS-authorised inspection station and pay for your pink slip. The Service NSW website has a directory of AIS stations. You can also use a Service NSW mobile vehicle inspection where the inspector comes to a fixed inspection bay, but they still need the trailer brought to them.

Bring your previous rego papers and the receipt from us (we send an email summary of the work done) so you have a record of recent mechanical work if the inspector queries anything.

FAQ.

Why can you not issue the pink slip yourself?

Authorised Inspection Scheme accreditation is granted by Service NSW to specific licensed inspection premises. The accreditation requires a fixed location with calibrated equipment that has been inspected and certified. A mobile operator cannot meet the fixed-premises requirement under the current rules. This is the same reason national mobile mechanic chains like Lube Mobile do not issue pink slips. We can do the mechanical work; we cannot issue the certificate.

If you cannot issue the pink slip, what is the point of booking you?

Two reasons. First, you save the cost of failing an inspection (the AIS station charges whether you pass or fail, plus a re-inspection fee). Second, you save the hassle of dropping the trailer off, picking it up, returning to a fixer, picking it up again, going back to the AIS station. Booking us is one visit, at your location, after which you take a passing trailer to the inspection station once.

Can you recommend an AIS station?

Most petrol stations and tyre shops are AIS-accredited for light vehicles. Trailer-specific inspections are usually done at any AIS station that does cars and light commercials. The Service NSW website has a search tool by postcode. Look for "Authorised inspection scheme" on their site.

What if my trailer is over 4.5 tonnes ATM?

Heavy vehicles go through a different inspection process (HVIA - Heavy Vehicle Inspection Authority). We service trailers up to 4.5 tonnes ATM. Above that, you need a heavy vehicle specialist with HVIA accreditation.

What if I have not registered the trailer in years?

An unregistered trailer needs a Blue Slip inspection (formally an Unregistered Vehicle Inspection Report) rather than a Pink Slip. The Blue Slip is also issued by an AIS station, but with stricter criteria including a VIN/chassis check. We can still do the mechanical work that brings the trailer up to standard before you take it for the Blue Slip.

Do I need to be there for the inspection?

Not necessarily. We just need access to the trailer (driveway, storage yard, depot) and a power point and water tap within 20 metres. If you cannot be there, leave a key for any locks or have the trailer accessible. We send photos and an emailed summary of what we found and what we did.
