When it comes to keeping your truck roadworthy in New South Wales, the annual pink slip inspection — officially known as an eSafety check — is a legal requirement for vehicles five years or older. For truck owners and operators, this inspection is not just a routine task, but a critical part of ensuring safety, compliance, and operational reliability.

Failing a pink slip inspection can lead to costly delays, re-inspections, and even downtime that impacts your schedule and business. Understanding the most common reasons for failure helps you prepare properly and avoid any unpleasant surprises.

In this article, we explore the top issues that could cause your vehicle to fail and how a professional Pink Slip Truck Inspection Service can support you through the process.

1. Worn or Unsafe Tyres

Tyres are among the most common failure points during a pink slip inspection. Trucks require tyres that meet strict standards for tread depth, wear, and structural integrity. If your tyres are bald, unevenly worn, or have visible damage such as cracks or bulges, your truck will not pass.

Make sure all tyres, including the spare, have at least 1.5mm of tread depth across the entire surface. It’s also worth checking for proper inflation and ensuring no metal cords are exposed.

2. Faulty or Inadequate Braking System

Given the size and weight of most trucks, a fully functional braking system is vital. During a pink slip inspection, examiners will check the brake pads, discs, fluid levels, and handbrake operation.

Brake pads that are too thin, worn rotors, or leaking brake fluid can lead to an immediate failure. Unusual noises, vibrations, or longer stopping distances are all signs that your braking system may need attention before inspection day.

3. Damaged or Inoperative Lights

Another frequent reason for inspection failure is faulty lighting. All truck lights — including headlights, brake lights, tail lights, indicators, and number plate lights — must be in full working order.

Bulbs that are blown, dim, or incorrectly aligned can result in non-compliance. It’s a simple fix, so be sure to test all lights before your inspection and replace any faulty bulbs or fuses in advance.

4. Oil Leaks and Fluid Leaks

Visible oil leaks from your engine, gearbox, or differential are a major red flag during an inspection. Leaking fluids not only pose a mechanical risk but also a safety and environmental concern.

Check beneath the truck for signs of fluid dripping or pooling. If leaks are present, have them addressed by a qualified mechanic before booking your inspection.

5. Exhaust System Faults

Your truck’s exhaust system is another critical area. Inspectors will look for excessive noise, rust damage, or signs of leaking exhaust gases. A faulty exhaust can result in poor emissions performance and pose a risk to both the driver and the environment.

Trucks must meet emissions standards appropriate to their age and class. Any modifications to the exhaust system should also comply with legal requirements.

6. Suspension and Steering Issues

Poor handling, clunking noises, or uneven tyre wear might indicate problems with your suspension or steering components. During the inspection, the technician will examine shock absorbers, ball joints, tie rods, and steering rack condition.

Loose, worn, or damaged suspension parts can compromise road safety and lead to inspection failure. Regular servicing can help catch these issues early.

7. Windscreen and Wiper Problems

A chipped or cracked windscreen that obstructs the driver’s view will result in a failed inspection. Likewise, faulty wiper blades or a non-functioning washer system are grounds for non-compliance.

Make sure the wipers operate smoothly and that your windscreen washer bottle is topped up and functional. If there’s any damage to the glass, have it assessed and repaired beforehand.

8. Seatbelts and Interior Safety Features

Your truck’s interior safety equipment — such as seatbelts, horn, and warning lights — must be in working order. Seatbelts must retract properly, lock during sudden stops, and show no signs of fraying or damage.

Inspectors will also ensure the driver’s seat is secure and that the dashboard indicators (such as check engine lights or ABS warnings) behave correctly when the ignition is turned on.

9. Body Condition and Structural Integrity

Trucks with excessive rust, sharp body panels, or damaged structural components will not pass inspection. While cosmetic wear is not typically a problem, anything that compromises vehicle integrity or pedestrian safety is a concern.

Regular visual inspections can help you catch corrosion or panel damage early and have it repaired before it becomes a larger issue.
