So, you’ve got yourself a shiny new box trailer, maybe even from King Trailers & Towbars — nice one! Whether you’re moving house, going camping, hauling mulch, or setting off on a Bunnings run that got wildly out of hand, there’s one thing you need to know:
Towing a trailer is NOT the same as just driving with a heavier car.
Do it wrong, and you’ll end up fishtailing down the highway like a confused salmon — or worse, slapped with fines from a high-vis-clad ranger in rural Victoria. So let’s make sure you tow like a pro, not a plonker.
🚚 First Up: What Even Is a Box Trailer?
A box trailer is basically a metal workhorse on wheels — perfect for tradies, road trippers, and anyone who finds their boot space lacking when it's time to "just grab a few things."
At KingTowbars and Trailers, you’ll find a range of durable trailers ready to handle whatever you throw at them (hopefully not literally). From 6x4 singles to heavy-duty tandem axles, there’s one for every job — but towing them? That’s where the real skill lies.
⚖️ Load Distribution: The Art of Not Flipping Out
Picture this: you chuck all the heavy gear at the back of your trailer and wonder why your steering feels like you’re on a slip ’n slide. Welcome to bad load distribution, the number-one cause of "oh no" moments on Aussie roads.
✅ The 60/40 Rule:
-
60% of your load should sit in the front half of the trailer (ahead of the axle).
-
40% goes behind.
-
This keeps the tow ball weight stable — too light and it’ll fishtail, too heavy and your car’s front wheels will float like it's trying to take off.
Hot tip: Always tie down your load. A rogue lawnmower in the rearview mirror isn’t a great look.
🧮 Know Your Weights (Before the Highway Patrol Does)
1. Tare Weight: What your trailer weighs empty.
2. ATM (Aggregate Trailer Mass): The trailer + its maximum legal load.
3. GTM (Gross Trailer Mass): Weight on the trailer’s wheels when attached.
4. Tow Ball Load: How much weight your trailer applies to the hitch.
Confused? So are half the drivers on the road.
The golden rule:
🚗 Your vehicle must be rated to tow the trailer’s full ATM.
If you’re pulling a loaded 2000kg trailer with a hatchback from 2003, you’re not "giving it a go" — you’re giving the laws of physics a full-blown challenge.
Use your vehicle’s owner's manual, check your trailer's compliance plate, and don't forget to look up your state's legal limits. Or just buy from KingTowbars and Trailers, where the specs are as clear as a cloudless Nullarbor sky.
🛑 Braking Distances: Bigger Load = Longer Stop
Here’s a scary stat:
A trailer carrying just 500kg can double your braking distance — and that’s on dry roads.
Now imagine towing a tonne of gear in the rain, with tyres balder than your uncle Dave. Yeah… you’ll need brakes.
🚨 Australian Trailer Brake Laws:
-
Under 750kg ATM: No brakes required.
-
751kg–2000kg ATM: Needs override or electric brakes on at least one axle.
-
Over 2000kg ATM: Must have electric brakes on all wheels and an independent brake controller.
If that made your head spin, just remember: if it’s heavy enough to crush your big toe, it probably needs brakes.
🛣️ Towing Laws by State (Because It’s Never Just One Set of Rules)
In true Aussie fashion, each state and territory has its own little quirks when it comes to towing. Here's a cheeky breakdown:
| State | Speed Limit | Trailer Rego Required? | Other Notes |
|---|---|---|---|
| NSW | 100 km/h max | Yes | Must display rego plate, working lights, safety chains. |
| VIC | No specific towing limit | Yes | Mandatory breakaway system for over 2000kg trailers. |
| QLD | 100 km/h max | Yes | Load must not extend past 150mm either side of trailer. |
| SA | 100 km/h max | Yes | Brakes required over 750kg ATM. |
| WA | 100 km/h max | Yes | Load cannot protrude beyond 2.5m total width. |
| TAS | 100 km/h max | Yes | Chains and reflectors required. |
| NT | 100 km/h (officially...) | Yes | Be extra careful on unsealed roads. |
| ACT | 100 km/h max | Yes | Brakes and lights must meet ADR standards. |
Wherever you're going, check your local regs — and don’t rely on the bloke at the servo for legal advice.
🪝 The Hitch Bit: Not All Tow Balls Are Created Equal
Make sure your towbar is rated for your trailer’s ATM — stamped right on the compliance plate. Also:
-
Use D-shackles that meet Australian standards.
-
Safety chains should cross under the hitch, not just hang loosely like spaghetti.
-
Regularly inspect the hitch for rust, cracks or dodgy welds. That $20 second-hand bargain on Gumtree might be a ticking time bomb.
🎯 Bonus Tip: Practice Before You Look Like a Wally
Towing a trailer isn't hard, but it does take a bit of practice. Find a quiet paddock or industrial area and try:
-
Reversing in a straight line (harder than it sounds)
-
Turning corners without mounting curbs or embarrassing yourself
-
Emergency stops with weight in the trailer
And remember: slow is smooth, smooth is safe.
