Towing a trailer in Australia opens up countless possibilities — from transporting machinery and farm equipment to moving house or enjoying outdoor adventures. But with these benefits comes responsibility: unsafe trailer use can lead to accidents, fines, and costly damage.
In this article, we highlight 7 common trailer safety mistakes Australian drivers often make, and how you can avoid them. We also share a simple pre-trip safety checklist to keep every journey safe.
1. Overloading the Trailer
Many owners underestimate how quickly a trailer can become overloaded. Carrying more than the rated capacity affects braking, stability, and can cause serious accidents.
Always check your trailer’s Gross Trailer Mass (GTM) and never exceed it.
2. Incorrect Hitch Connection
A poorly secured tow ball or hitch pin is one of the most common causes of trailer detachment.
Double-check the coupling lock and safety chains before driving.
3. Ignoring Braking Systems
Trailers over 750kg GTM in Australia generally require brakes. Skipping brake maintenance can cause extended stopping distances.
Regularly test electric or mechanical brakes, and service them as recommended.
4. Poor Load Distribution
Even when loads are within weight limits, uneven distribution can make towing unsafe.
Place 60% of the weight over the front half of the trailer. Keep the load balanced left to right.
5. Neglecting Lights and Indicators
Faulty tail lights or missing reflectors not only break the law but also increase accident risk at night or in bad weather.
Inspect wiring and bulbs before every trip.
6. Tyre Pressure and Wear
Under-inflated or worn tyres reduce traction and stability.
Inflate to the manufacturer’s specifications and check tread depth regularly.
7. Skipping Regular Maintenance
Rust, cracked welds, or worn bearings can lead to sudden breakdowns.
Follow a routine maintenance schedule and have your trailer inspected annually.
Trailer Laws and Rules in Australia
Australia enforces strict towing regulations through the Australian Design Rules (ADRs). Depending on the state, you may face fines if:
- Your trailer exceeds weight limits
- Brakes and lights are faulty
- Registration is missing or expired
Always check your local state transport authority for the latest compliance requirements.
Pre-Trip Trailer Safety Checklist
Before hitting the road, run through this quick safety check:
- Hitch locked and safety chains secure
- Load evenly distributed and tied down
- Brakes tested
- Lights and indicators working
- Tyres inflated and no visible damage
Final Thoughts
Trailer safety is not just about following rules. It is about protecting your family, your cargo, and others on the road. By avoiding these common mistakes and sticking to a simple checklist, you can tow with confidence every time.
