A heavy vehicle inspection checklist helps you find defects before an NHVR officer or a police officer does. It covers the same things an inspector looks at, like brakes, couplings, steering, tyres, lights and the vehicle’s structure, so you can fix problems before they turn into a defect notice or a breakdown.
Defects are common. In the NHVR’s 2024 National Roadworthiness Survey, 22% of powered units had a minor non-conformity. The rules have also just changed: since 1 August 2026, inspections use a new version of the national inspection manual. This guide covers what an NHVR inspection checks, a section-by-section checklist, how often to inspect, and what happens if a defect is found. There’s also a printable daily check you can hand to your drivers.
What is the NHVR heavy vehicle inspection checklist?
The NHVR heavy vehicle inspection checklist is a one-page form based on the National Heavy Vehicle Inspection Manual (NHVIM). The NHVIM sets national failure criteria for every vehicle over 4.5 t GVM. Authorised officers, inspection stations and operators all use the same criteria, so a defect in one state is a defect in every state.
The current version is NHVIM V3.2, which replaced V3.1 on 1 August 2026. It’s split into 16 sections:
| Sections 1 to 8 | Sections 9 to 16 |
| 1. Vehicle identification | 9. Mirrors and indirect vision devices |
| 2. Brakes | 10. Windscreens and windows |
| 3. Couplings | 11. Engine, driveline and exhaust |
| 4. Steering and suspension | 12. LPG, NG, hydrogen and electric vehicles |
| 5. Wheels, tyres and hubs | 13. Buses |
| 6. Structure and body condition | 14. Trailers |
| 7. Seats and seatbelts | 15. Motorhomes, caravans and campervans |
| 8. Lights and reflectors | 16. Vehicle dimensions |
Alongside the manual, the NHVR publishes two example checklists, one for heavy vehicles and one for heavy trailers, both updated in August 2026. They’re marked “example only”. The NHVIM criteria are what count, so use the checklist as a guide and the manual for the detail.
Heavy vehicle inspection checklist: what to check
These are the areas inspectors focus on most, in the same order as the NHVIM.
Vehicle identification
Start by making sure the vehicle is the one on the paperwork. The VIN or chassis number must match the compliance plate and the registration. Check the number plates are secure and readable. An obscured or illegible plate is enough for a defect notice on its own.
Brakes
Brakes are the most important system on the checklist, and the most common reason a vehicle gets grounded.
- Service brake and park brake both work and hold
- No air leaks, and air pressure builds up properly
- Brake hoses and lines aren’t cracked, bulging, chafed or leaking
- Low-pressure warning devices work
- Trailer breakaway protection works
As a performance benchmark, the NHVR checklist notes that the service brake must stop a heavy vehicle built after 1930 within 16.5 m from 35 km/h.
Couplings
A failed coupling can separate a trailer at speed, so check every connection:
- Fifth wheel and kingpin aren’t worn, cracked or loose, and the locking jaws are fully engaged
- Tow couplings, drawbars and safety chains are secure and undamaged
- No excessive movement between coupled parts
- Air and electrical connections between the truck and trailer are secure
Steering and suspension
Look for anything that affects control:
- No excessive free play at the steering wheel
- No leaks from the power steering
- Springs aren’t broken or cracked, and mounts and U-bolts are secure
- Air suspension holds pressure and sits level
Wheels, tyres and hubs
Tyre and wheel defects are among the easiest to spot and the easiest to fix:
- Tread depth is at least 1.5 mm, with no cuts, bulges or exposed cords
- All wheel nuts are present and tight, with no signs of movement
- Rims and wheels aren’t cracked or damaged
- No oil leaking from the hubs
Structure and body condition
- No cracks or heavy corrosion on the chassis rails and crossmembers
- Mudguards, bumpers and rear marker plates are fitted and secure
- No sharp or dangerous protrusions
- Doors, bonnet, catches and tailgates close and lock properly
Seats, seatbelts, mirrors and windscreen
The old version of this post skipped these, but inspectors don’t:
- Seats are secure, and every seatbelt latches, retracts and isn’t frayed
- Mirrors are in place, secure and not cracked
- Windscreen cracks aren’t in the driver’s line of sight, and the wipers and washers work
Lights and reflectors
- Headlights, tail lights, brake lights, indicators and hazard lights all work
- Reflectors and conspicuity markings are in place and visible
- Lenses aren’t cracked or missing
A cracked lens or one failed brake light, when the others still work, is a typical example of a minor fault that can still earn a self-clearing defect notice.
Engine, driveline and exhaust
- No major oil, fuel or coolant leaks
- The exhaust is secure, doesn’t leak into the cabin, and is guarded where people could touch it
- Driveshafts and universal joints are secure
Printable daily heavy vehicle inspection checklist
The sections above are what an inspector checks. Your drivers need something quicker for every shift, and the easiest way is to skip the paper.
In Manage Vehicle, drivers complete their daily inspection, record the odometer reading and report any faults directly in the platform. Your maintenance team sees what needs attention as soon as it’s logged, instead of finding out when a checklist turns up at the depot days later.
That’s how Brandon Manion Coaches keeps on top of maintenance across its bus fleet. Their information used to be spread across driver checks and maintenance records. Now drivers log inspections and faults in one place, the maintenance team has an up-to-date view, and fewer issues get missed.

Remember that a driver’s daily check counts as work time for fatigue purposes, so it needs to go in the work diary as work. If your drivers do a full pre-trip routine, our pre-trip inspection checklist walks through it step by step.
How often should heavy vehicles be inspected?
There’s no single national schedule. Inspections happen at three levels:
- Daily, by the driver. A walk-around check before each shift, using a checklist like the one above.
- Scheduled maintenance. Servicing at the intervals in the manufacturer’s specs or your maintenance system, plus a full inspection against the NHVIM at regular intervals.
- State periodic inspections. Some states tie inspections to registration. NSW requires an inspection to register or renew many heavy vehicles, and Queensland requires a certificate of inspection for many heavy vehicles. Victoria has no regular periodic inspection. Check with your state road authority for your vehicle type.
Under the Heavy Vehicle National Law, you can’t rely on an annual inspection alone. Operators and everyone in the chain of responsibility have a duty to keep vehicles safe, every day they’re on the road.
What happens if a defect is found?
If an authorised officer finds a defect at the roadside or during an inspection, they can issue a defect notice. There are three types, based on the level of risk:
| Defect notice | When it’s issued | Can you keep driving? |
| Major | The vehicle poses an imminent and serious safety risk | Only to move it as the notice allows, or after repairs. A defective vehicle label is fitted |
| Minor | There’s a safety risk, but not an imminent or serious one | Yes, under conditions set in the notice, until the date it gives |
| Self-clearing | No safety risk, or the number plate is obscured or illegible | Yes, for up to 28 days while you fix it |
Major and minor notices need an inspection to clear them. A self-clearing notice doesn’t need an inspection, but you still have to fix the fault and clear the notice by following its instructions.

Frequently asked questions
What does an NHVR inspection check? An NHVR inspection checks the vehicle against the National Heavy Vehicle Inspection Manual (NHVIM V3.2 since 1 August 2026). That includes identification, brakes, couplings, steering and suspension, wheels and tyres, structure, seats and seatbelts, lights, mirrors, windscreen, and the engine, driveline and exhaust.
How often should heavy vehicles be inspected? Drivers should do a daily check before each shift. Vehicles should also be serviced and fully inspected at regular intervals set by the manufacturer or your maintenance system. Some states, such as NSW and Queensland, also require periodic inspections linked to registration.
What happens if a defect is found? An authorised officer can issue a major, minor or self-clearing defect notice. A major defect means the vehicle can only be moved as the notice allows until it’s repaired. A minor defect lets you keep driving under conditions until a set date. A self-clearing defect gives you up to 28 days to fix it.
Is the NHVR inspection checklist mandatory? The NHVR’s checklist is marked “example only”. What’s mandatory is that your vehicle meets the standards, and inspectors judge that against the NHVIM failure criteria. Using a checklist is the easiest way to make sure you check everything.
Where can I download the NHVR heavy vehicle inspection checklist? The NHVR publishes its heavy vehicle and heavy trailer inspection checklists on its NHVIM page. You can also download our printable daily heavy vehicle inspection checklist above.
