Truck Pre-Start Checklist: 10 Must-Have Items for Every Trip

Around 18 per cent of road crash deaths in Australia involve a heavy vehicle, based on 2019 national figures, even though heavy vehicles crash less often than other vehicles (Australian Government heavy vehicle safety fact sheet). A thorough daily pre-start is one of the simplest ways to reduce that risk. This guide covers the 10 items every truck pre-start checklist should include, the mistakes that undermine it, and how to line your checks up with NHVR guidance.

Why daily pre-start checks matter

A pre-start is a quick visual and functional inspection before a truck leaves the yard, depot or rest area. The NHVR’s Creating heavy vehicle daily checks guide sets out the key systems to check and makes clear that operators are responsible for keeping their vehicles roadworthy.

Daily checks help prevent breakdowns, roadside defect notices and serious incidents caused by problems such as worn tyres, faulty lights or brake faults. They also support Chain of Responsibility obligations by showing that reasonable steps were taken to find and fix mechanical risks. For more on those obligations, see our guide to Chain of Responsibility compliance.

10 essential truck pre-start checklist items

Every fleet should tailor its pre-start to suit its vehicles and operations, but most daily checks should cover at least these 10 items.

1. Brakes and parking brake

Check that the service brakes work correctly, warning lights go out, and the parking brake holds the vehicle on a gentle slope. Listen for air leaks and check air pressure where fitted.

2. Tyres, wheels and rims

Inspect tread depth, sidewalls and inflation. Look for cuts, bulges, exposed cords or mismatched tyres. Check wheel nuts and rims for cracks, missing nuts or signs of movement. Our guide to wheel nut inspection covers this in more detail.

3. Lights, indicators and reflectors

Test headlights, tail lights, brake lights, indicators, hazard lights, clearance lights and number plate lights. Clean dirty lenses and check reflectors are present and visible.

4. Steering and suspension

Check for excessive play in the steering wheel, unusual noises when turning, and any visible damage or leaks in steering and suspension components during the walk-around.

5. Load restraint, body and couplings

Confirm the body, tray, tailgate, curtains or doors are sound and secure. Inspect restraints, gates, chains, straps and anchor points. On combinations, check the coupling, kingpin, safety chains and air and electrical connections.

6. Windscreen, windows and wipers

Look for cracks or chips that could block the driver’s view, check glass is clean, and make sure the wipers and washers work.

7. Oil, coolant and fluid leaks

Check under the vehicle for fresh oil, fuel, coolant or hydraulic leaks. Confirm fluid levels are within range and caps and filler points are secure.

8. Safety equipment

Check the fire extinguisher is charged and accessible, the first aid kit is stocked, wheel chocks and warning triangles are on board where required, and any PPE needed for the job is available.

9. Mirrors, cameras and visibility aids

Check mirrors are correctly adjusted and undamaged. Test reversing cameras, proximity sensors and any other visibility aids.

10. Cabin, controls and warning lights

Make sure the cabin is free of loose items that could interfere with the pedals or controls, the seat and seatbelt are in good condition, and no warning lights are showing before departure.

What to do when a check fails

A pre-start is only as useful as what happens to the defects it finds. Every fleet needs a clear defect process that drivers know and follow.

1. Record the defect. Note what failed and where, and add a photo if you can.
2. Assess whether the truck is safe to drive. Brake faults, major tyre damage, steering problems or serious leaks usually mean the truck stays in the yard.
3. Notify the supervisor or workshop. Follow your organisation’s defect procedure so the right person knows straight away.
4. Assign and complete the repair. Give the fix an owner and a due date, and keep the truck out of service until safety-critical work is done.
5. Sign the vehicle back into service. Record what was repaired, by whom and when, so there is proof the defect was fixed.

Common truck pre-start mistakes

Most pre-start failures are not about the checklist itself. They come from how it is used.

• Ticking without looking. Rushing through the list, or completing it from memory, defeats the purpose. Walk around the truck and physically check each item.
• Using a generic checklist. A form that doesn’t match the vehicle, trailer or load gets skipped or half-completed. Tailor the list to each vehicle type.
• Forgetting the trailer. Couplings, trailer lights, tyres and load restraint need checking every time a trailer is hooked up, not just at the start of the day.
• Not reporting minor defects. Small issues left unreported become breakdowns and roadside defects. Every defect should be recorded, even if it isn’t safety-critical.
• Driving with a known fault. If a safety-critical item fails, the truck should not leave until it is repaired or cleared by the workshop.
• Paper forms nobody reads. A defect written in a pre-start book that never reaches the workshop won’t get fixed. Make sure completed checks are reviewed daily.
• No close-out record. Without proof of the repair, you can’t show an auditor that the defect was dealt with.

Training helps with all of these. Our guide to implementing a truck pre-start program covers driver training and audits.

Pre-starts on short-haul and multi-drop work

Short-haul and local delivery work puts different pressure on pre-starts. Trucks do many short trips, drivers may swap vehicles during the day, and trailers are often changed between runs. It is easy to assume a quick trip doesn’t need a proper check.

• Complete a full pre-start at the start of each shift, whatever the trip length.
• Repeat the coupling, trailer light, tyre and load checks each time a different trailer is hooked up.
• Do a quick walk-around after loading or unloading to check restraints, gates and doors.
• If a different driver takes over the truck, they should do their own pre-start.

Aligning your truck pre-start checklist with NHVR

The NHVR daily checks guide explains that operators should tailor daily checks to their fleet while covering core systems such as brakes, tyres and wheels, lights, couplings and vehicle structure. Mapping each item on your pre-start to one of those systems helps show your process addresses the relevant risks.

When a defect is reported, your records should show how it was assessed, repaired and signed off before the vehicle returned to service. For fleets operating across several states or depots, a single standard checklist also simplifies training, because every driver follows the same process wherever they start.

Digital truck pre-start checks

Paper pre-start books get lost, are hard to read and are slow to reach the workshop. With a digital checklist, drivers tap through each item on a phone or tablet, photograph any defect and submit the check from the yard. Checklists can be completed without coverage and submitted with a tap once the device is back online.

With the DIGI CLIP truck pre-start checklist app, failed items flow straight into the Action Log, where they are assigned, tracked and closed out with evidence. Overdue actions trigger alert emails, and every record can be exported to PDF or Excel for audits.

Illustrative scenario: moving a mixed fleet off paper

Picture a mid-sized freight operator running prime movers and rigid trucks across several depots, still using paper pre-start books. Completed books are handed in late or misplaced, and the workshop spends time hunting through forms for reported defects. After moving to digital pre-starts, drivers complete checks on their phones with photos of any defects, and the workshop sees open issues each morning in the Action Log. Records can be searched by vehicle, driver and date when an auditor or customer asks.

This scenario is illustrative. It shows how a fleet could use DIGI CLIP and is not an account of a specific customer.
