Speed limits, trailer brakes, load rules, licensing, and registration requirements for towing in New South Wales.
Important disclaimer: This page provides a plain-language summary of NSW towing regulations for general guidance only. Regulations can change. Always verify current rules directly with Transport for NSW or NSW Police before towing. This is not legal advice.
Towing in NSW is governed by the Australian Road Rules, the Road Transport Act, and regulations administered by Transport for NSW. Here are the key rules you need to know before you tow.
| Vehicle Type | Rule |
|---|---|
| Light vehicle towing trailer GVM up to 4,500 kg — covers most cars, utes, and SUVs |
Comply with the posted speed limit. There is no separate reduced limit for towing a trailer. On a road posted at 110 km/h you may legally travel at 110 km/h. |
| Heavy vehicle towing trailer GVM over 4,500 kg — trucks, heavy utes, etc. |
Capped at 100 km/h under the Heavy Vehicle National Law (HVNL), regardless of the posted limit. |
| All vehicles — school zones, built-up areas | Posted limit applies. No exceptions. |
Important clarification: In NSW, light vehicles (GVM up to 4,500 kg) towing a trailer are not subject to a blanket 100 km/h cap. You must comply with the posted speed limit — the same as if you weren't towing. The 100 km/h cap applies only to heavy vehicles (GVM over 4,500 kg) under the Heavy Vehicle National Law. That said, driving at or below 100 km/h is strongly recommended when towing any trailer — stopping distances increase significantly, and trailer stability reduces at higher speeds.
Check your vehicle's towing capacity in the owner's manual or on the manufacturer's website. Do not assume — every vehicle is different.
| Trailer ATM | Brake Requirement |
|---|---|
| Up to 750 kg | No brakes required |
| 751 kg – 2,000 kg | Brakes required — overrun or electric |
| Over 2,000 kg | Electric brakes required — We use Elecbrakes and their dedicated app |
Our heavier trailers are fitted with overrun brakes and/or electric brakes (Elecbrakes EB2 system) to meet legal requirements. If your trailer has electric brakes, see the Electric Brakes Guide to set them up correctly.
Safety chains are required by law in NSW. Under the Australian Road Rules (Rule 215) and NSW road transport legislation, a towed vehicle must be connected to the towing vehicle by safety chains in addition to the coupling. Chains must be crossed under the drawbar. Driving without safety chains is an offence — fines and defect notices apply.
Check your current licence conditions on your licence card or via Service NSW.
Under the Australian Road Rules and NSW road transport legislation, you are legally responsible for ensuring your load is properly secured at all times. If anything falls from your trailer and causes damage, injury, or death — you can be held liable. Fines for unsecured loads can be significant. Use rated tie-down straps, cargo nets, and tarps as required for your load type.
| Rule | Requirement |
|---|---|
| Lights | Trailer must have working tail lights, brake lights, and indicators visible from 200 m. Lights must be on when driving. |
| Reflectors | Trailer must have rear reflectors. Must not be obscured by load. |
| Number plate | Must be clearly readable, properly mounted, and illuminated after dark. |
| Overhanging loads — rear | Loads extending more than 1.2 m past the rear of the trailer must be marked with a red flag (day) or red light (night). Verify current requirements with Transport for NSW. |
| Overhanging loads — sides | Loads extending more than 150 mm beyond the sides of the trailer may require marking or may be prohibited — check with Transport for NSW. |
| Wide loads | Loads exceeding 2.5 m wide require a permit and pilot vehicles. This is beyond the scope of standard hire — contact Transport for NSW if relevant. |
| Passengers in trailers | Illegal. No person may travel in or on a trailer being towed on a public road in NSW. |
| Animals | Livestock transport must comply with ASEL standards and NSW animal welfare legislation. See Packing Tips — Cattle Trailer. |
Towing regulations differ between states and territories. If you are travelling across a state border with a Croc Hire trailer, you are legally required to comply with the rules of each state you drive through — not just NSW.
| State / Territory | Key Difference from NSW | Check With |
|---|---|---|
| Queensland | Light vehicles towing a trailer are capped at 100 km/h, regardless of the posted speed limit — even on 110 km/h roads. This is stricter than NSW. | TMR Queensland |
| Victoria | Generally similar rules to NSW for light vehicles. Verify current speed and brake requirements before travelling. | VicRoads |
| ACT | ACT follows the Australian Road Rules closely. Generally similar to NSW for light vehicle towing. | Access Canberra |
The table above is a general guide only and may not be current. Before crossing any state border with a trailer, check the specific regulations for that state directly with the relevant transport authority. Claiming you didn't know the local rules is not a defence against an infringement notice.
Verify everything with the official source. Laws change and this summary may not reflect the most current rules. Always check with Transport for NSW or a qualified traffic lawyer before making decisions based on this information. We are a trailer hire company, not a legal authority.
