Short answer
A trailer pre-trip checklist records the driver's check of the coupling, chains, breakaway, brakes, tyres, lights, structure and load restraint before towing. No Australian law prescribes the form. HVNL section 89 bars using an unsafe heavy vehicle on a road (over 4.5 t, outside WA and the NT), and section 26C sets a primary duty. In the US, 49 CFR 396.13 sets pre-trip duties for covered commercial motor vehicle drivers.
Checked against Heavy Vehicle National Law (HVNL) (Current as at 1 August 2026, incorporating the Heavy Vehicle National Law Amendment Act 2025 (Queensland)) on by the MapTrack templates team. How we check templates
Key takeaways
- The MapTrack trailer pre-trip checklist contains 34 checks across 7 sections. Sections covered: Coupling & Hitch, Safety Chains & Electrical, Brakes, Tyres & Wheels, Lights & Reflectors, Chassis & Body, Load Restraint.
- The HVNL covers trailers over 4.5 t ATM and combinations that include a heavy vehicle, in participating jurisdictions only (not WA or the NT).
- HVNL section 26C is a primary duty, so far as is reasonably practicable; it doesn't prescribe a documented pre-trip inspection.
- Under 49 CFR 396.13, the driver reviews and signs the last required inspection report before driving; no signature is needed for defects on a dropped towed unit.
- A failed coupling, safety chain, breakaway or brake item keeps the combination off the road until it is repaired.

What is a trailer pre-trip checklist?
A trailer pre-trip inspection checklist is a structured form completed by a driver or operator before towing a trailer on public roads or worksites. It covers the coupling and hitch assembly, braking system, tyres and wheels, lighting and electrical connections, load restraint, structural integrity and safety equipment. The checklist ensures the trailer is roadworthy, the load is secure and the combination vehicle can be operated safely. MapTrack digitises trailer pre-trip inspections so every check is recorded against the trailer asset record with timestamped photos, GPS location and automatic defect escalation to maintenance teams.
Trailer pre-trip inspections are a practical way to meet Chain of Responsibility (CoR) duties in Australia and FMCSA driver duties in the United States, although neither prescribes a pre-trip inspection form. The Heavy Vehicle National Law prohibits using, or permitting the use of, an unsafe heavy vehicle on a road (section 89), and requires each party in the chain of responsibility to ensure the safety of its transport activities so far as is reasonably practicable (section 26C). A documented pre-trip inspection demonstrates that the driver and the organisation fulfilled their duty of care. Failing to complete a pre-trip inspection exposes the driver, operator and consignor to significant penalties under CoR, including personal liability for directors and managers. Section 19 of the WHS Act 2011 reinforces this obligation by requiring PCBUs to ensure, so far as is reasonably practicable, that plant under their control is maintained in a safe condition, which includes trailers used as part of work activities.

Benefits of using this trailer pre-trip checklist
- Legal compliance: a completed pre-trip record supports NHVR Chain of Responsibility obligations and FMCSA 49 CFR 396.13 driver inspection requirements
- Coupling safety: systematic checks of the hitch, safety chains, breakaway system and electrical connector prevent separation incidents on the road
- Brake assurance: verifying brake function, air line connections and breakaway brake activation before departure reduces the risk of runaway trailers
- Tyre condition: checking tyre pressure, tread depth, sidewall condition and wheel nut torque prevents blowouts and rim failures at highway speed
- Load security: confirming load restraint meets the Load Restraint Guide requirements prevents load shift, spillage and serious road incidents
- Defect escalation: digital inspections in MapTrack automatically raise work orders for failed items so maintenance teams can respond before the trailer is dispatched

What to include in a trailer pre-trip checklist
This trailer pre-trip checklist covers 8 key areas:
- Coupling and hitch: verify coupling is fully engaged and locked, safety chains are crossed under the tongue, breakaway cable is connected and the electrical plug is secure with no exposed wires
- Braking system: test trailer brakes independently, check air or hydraulic brake line connections for leaks, verify breakaway brake activates when the lanyard is pulled and confirm the handbrake holds on a grade
- Tyres and wheels: inspect tread depth across the full width, check for cuts bulges or sidewall damage, confirm tyre pressures meet the placard specification and verify wheel nuts are torqued to the manufacturer setting
- Lights and electrical: confirm all tail lights, brake lights, indicators and clearance markers are functioning, check the electrical connector pins for corrosion and verify the number plate light is operational
- Structural integrity: inspect the chassis, drawbar, cross-members and welds for cracks, corrosion or distortion, check mudguards, splash guards and any fitted toolboxes for security
- Load restraint: verify the load is restrained in accordance with the Load Restraint Guide, check tie-down straps, chains or gates for condition and correct tension, confirm the load does not exceed the aggregate trailer mass (ATM)
- Safety equipment: confirm the trailer has reflective markings or tape in place, a wheel chock is available, and a fire extinguisher is accessible where required by site or regulatory rules
- Registration and compliance: verify the trailer registration label is current, the compliance plate is legible and any required annual inspection or roadworthy certificate is valid
How to use this trailer pre-trip checklist
- Walk-around inspection: start at the coupling and walk clockwise around the trailer, visually checking the hitch lock, safety chains, breakaway cable, chassis, tyres, lights, load restraint and structural condition before connecting power
- Connect and test electrics: plug in the electrical connector and have a second person confirm that tail lights, brake lights, indicators and clearance markers all illuminate correctly at the rear of the trailer
- Test brakes: apply the trailer brakes independently using the in-cab controller or breakaway lanyard, confirm the wheels lock, then release and check for free rotation without dragging
- Inspect tyres and wheels: check each tyre for tread depth, sidewall damage, correct pressure and any embedded objects, then verify wheel nuts are tight by applying a torque wrench or using a check pattern
- Verify load restraint: confirm the load is within the rated capacity, check that all tie-downs are tensioned correctly and that the load cannot shift forward, rearward or laterally during transport
- Record and sign off: complete the checklist in MapTrack or on the printed form, note any defects found, attach photos of damage or concern items, sign and date the inspection before departing

A trailer pre-trip inspection must be completed before every trip or at the start of each shift if the trailer remains coupled overnight. Under NHVR Chain of Responsibility legislation, every party in the chain must ensure, so far as is reasonably practicable, the safety of its transport activities relating to a heavy vehicle and its combination (section 26C). FMCSA 49 CFR 396.13 requires drivers in the United States, before driving, to be satisfied the vehicle is in safe operating condition and to review and sign the last driver vehicle inspection report where one was required.
For trailers used on construction sites or mine sites, a pre-start inspection is typically required at the beginning of each shift regardless of whether the trailer travels on public roads. The Heavy Vehicle National Law does not itself set periodic roadworthy inspections, so check whether your state or territory registration rules require them. Regular pre-trip inspections complement these periodic checks by catching defects between formal inspections.
