What Are The Legal Requirements For Towing In Australia?

Towing laws in Australia have evolved, and a uniform approach has been adopted since the introduction of new regulations in December 1998. However, it's essential to recognise the subtle variations across states and territories.

1. Speed Limits:

For a motor vehicle and trailer combination under 4.5 tonnes GCM (Gross Combined Mass), posted speed limits apply. In Western Australia, a specific 100km/h speed limit applies when towing, unless the manufacturer prescribes a lower limit.

For combinations exceeding 4.5 tonnes GCM, drivers should consult their respective state or territory transport authority for speed limits, ensuring a safe speed, satisfactory stopping distance, and compliance with the vehicle manufacturer's requirements.

2. Maximum Trailer Mass:

The allowable maximum mass for a trailer is either the capacity of the tow vehicle's towing attachment (towbar) or the towing capacity specified by the vehicle manufacturer, whichever is less. Trailers exceeding 750kgs GTM (Gross Trailer Mass) must have brakes.

3. Legal Requirements:

A national regulation implemented in December 1998 restricts the mass a vehicle can tow. Prospective trailer or caravan buyers must carefully consider their vehicle's towing mass and construction, as indicated in the vehicle manufacturer's handbook. Towing mass specifications include trailer weight capacity and ball weight capacity, both of which must not be exceeded.

If the manufacturer hasn't specified a recommended tow mass, the vehicle can tow one and a half times its unladen mass if the trailer has brakes. Without brakes, the maximum permissible towing capacity is 750kgs.

The tow vehicle's body must be sturdy enough to attach a towbar suitable for the intended trailer, and modifications may be necessary, such as fitting load levelling devices, electrical connections, brake controllers, extra mirrors, and transmission oil coolers.

4. State-Specific Considerations:

• New South Wales (NSW): Road rules set a maximum speed of 100km/h for a tow vehicle and caravan with a combined weight of more than 4500kg.
• Queensland (QLD): Towing requires additional driving skills and safety precautions, and drivers must adapt to the conditions. A Safe Towing Information Booklet is available for reference.
• Western Australia (WA): WA surpasses national regulations, imposing a maximum speed limit of 100km/h or the posted limit, whichever is less, regardless of caravan weight.
• Other States and Territories: General compliance with national regulations is crucial, but specific details may vary. It's advisable to consult local transport authorities for any additional regulations or recommendations.

Towing in Australia demands an understanding of both national and state-specific regulations. To ensure a seamless towing experience, prospective travellers should prioritise safety, adhere to speed limits, and comply with all legal requirements outlined by their respective state or territory.
