Most Brisbane caravan owners know the basics. Hitch up. Check the lights. Drive carefully. But the actual legal requirements around caravan towing in Queensland are more specific than most people realise — and the changes that came through in 2023 are still catching drivers out in 2026.

If you are looking for affordable tow truck in Brisbane after a caravan breakdown, or simply planning your next trip and want to know where you stand legally, this guide covers the caravan towing laws in Queensland that actually matter — clearly, without the legal jargon.

What Changed in 2023 and Why It Still Matters in 2026

Two significant changes happened in Queensland that every caravan tower needs to understand.

The GCM modification code

Queensland introduced a new Gross Combination Mass modification code in March 2023. Before this, the GCM of most light vehicles was fixed by the manufacturer and could not be legally increased. The new code changed that — allowing some light vehicles with a GVM up to 4,500 kilograms to have their GCM re-rated through an approved modification process.

This sounds like good news — and for some drivers, it is. If you were previously limited in what you could legally tow, a GCM upgrade through an approved modifier gives you more legal capacity. But the fine print matters.

A GVM upgrade does not automatically increase your GCM. A GCM upgrade does not automatically increase your towing capacity. The two are separate. And any modification must be carried out by an authorised modifier and mod-plated before it is legal on Queensland roads. Driving a modified vehicle without the correct certification is not a grey area — it is a defect waiting to happen.

ADR compliance for new trailers

Since 1 July 2023, all new trailers manufactured in Queensland must comply with the relevant Australian Design Rules rather than the old Vehicle Standards Bulletin 1. VSB1 is no longer an acceptable compliance method for new trailers.

If you bought a caravan or trailer before July 2023, nothing changes for your existing setup. If you have bought a new caravan or trailer since then, your dealer should have confirmed ADR compliance before delivery. If you are unsure — check the compliance plate on the van. An authorised certifier can confirm compliance status if needed.

The Core Requirements

These are the non-negotiables. Get any of these wrong and you are either unroadworthy, uninsured, or both.

GCM and towing capacity

The caravan towing laws in Queensland are clear on this: the loaded weight of your caravan cannot exceed your tow vehicle's rated towing capacity. And the combined weight of your fully loaded vehicle and fully loaded caravan cannot exceed the GCM listed on your vehicle's registration certificate.

The number that catches most Brisbane caravanners out is the loaded weight — not the manufacturer's listed weight for the van. A caravan that weighs 1,800 kilograms empty can easily weigh 2,400 kilograms loaded with water, food, clothes, tools, and gear. If your vehicle is rated for 2,000 kilograms towing, you are already over the limit before you leave the driveway.

Weigh your loaded caravan before every major trip. A public weighbridge visit takes ten minutes. A roadside defect and insurance complication takes considerably longer.

Safety chains

Queensland requires safety chains on all trailers and caravans. One chain for caravans with a Gross Trailer Mass up to 2,500 kilograms. Two chains for caravans between 2,501 and 3,500 kilograms. Both must be crossed under the drawbar in an X pattern — not parallel, not looped, not attached to a soft point on the vehicle.

The chains are not optional and they are not just for show. They are the last line of connection if the coupling fails. An officer can defect a combination on the spot for non-compliant safety chain setup.

Brake requirements

Any caravan with a GTM over 750 kilograms requires brakes. Between 751 kilograms and 2,000 kilograms, brakes are required on at least one axle. For caravans with a GTM over 2,000 kilograms, brakes are required on all wheels — and for electric brakes, a calibrated brake controller in the tow vehicle is mandatory.

A brake controller that is not calibrated correctly is a common problem we see. Either it is over-braking — which causes the caravan to drag and destabilise the combination — or it is under-braking, which means the caravan is pushing the tow vehicle under emergency stops. Neither is safe and neither is compliant.

Towing mirrors

If the caravan is wider than your tow vehicle's standard mirrors, extended towing mirrors are required by law. This is not a recommendation. Without them, you have no legal rear visibility and an officer can defect the combination at a roadside check.

Speed Limits When Towing a Caravan in Queensland

This is the one Queensland gets consistently wrong compared to other states — not the law, but the understanding of it.

Queensland does not have a separate blanket towing speed limit like some other states. The rule is to drive at a safe and appropriate speed for the conditions, within the posted speed limit for the road you are on.

But there is a catch most people miss. If your vehicle has a manufacturer-specified towing speed limit in the owner's manual — some vehicles specify a maximum towing speed of 100 kilometres per hour regardless of the posted limit — then that manufacturer limit applies legally. Exceeding it is a compliance issue, not just a mechanical risk.

For most drivers on Queensland highways, 100 kilometres per hour is appropriate for caravan towing — not because of a towing-specific law, but because road conditions and handling at higher speeds with a loaded van become a genuine safety risk.

When the Caravan Breaks Down Despite Everything Being Legal

Even a perfectly legal, perfectly prepared caravan setup has bad days. A tyre blows. A coupling component fails. The tow vehicle develops a mechanical issue with the van attached.

When that happens in Brisbane or anywhere across Southeast Queensland, the right response is the same regardless of how prepared you were.

Get the combination off the road if it can still move. Hazard lights on immediately. Stay in the vehicle on busy roads. Call a professional towing service that understands caravan combinations — not just standard vehicles.

We have attended caravan breakdown callouts across Brisbane where the driver's first mistake was accepting a tow from an operator who did not have the right equipment for a caravan combination. A standard car tow truck attempting to move a caravan and tow vehicle together creates more risk than it resolves. The right operator asks about the van, the combined length, and what has failed — before dispatching the right equipment.
