The NSW Road Transport Act and other relevant regulations outline the responsibilities of drivers when towing, covering aspects such as vehicle limits, speed restrictions, and load security.
Legal Towing Limits
- The total trailer mass must not exceed the vehicle’s rated towing capacity as specified by the manufacturer.
- The combined weight of the vehicle and trailer must comply with Gross Combination Mass (GCM) limits.
- Trailers exceeding 750 kg (Aggregate Trailer Mass – ATM) must be fitted with a braking system.
Speed Limits and Road Rules
- The caravan towing speed limit NSW is 100 km/h, even if the posted limit is higher.

These regulations are in place to reduce accidents and ensure road safety for both the driver and other motorists. Understanding and following these rules is essential for compliance and responsible towing.
Licence and Towing Restrictions
The type of driver’s licence you hold determines what you can tow under NSW towing regulations. Exceeding legal limits can result in fines, demerit points, or even loss of licence.
Towing with a Standard Licence
- Holders of a Class C (Car Licence) callows towing a trailer or caravan with a GTM of up to 4.5 tonnes.
- The towing vehicle and trailer combined must not exceed the manufacturer’s GCM limit.
- Learner and Provisional P1 drivers are not allowed to tow any trailer or caravan.

- A 3500 kg trailer can be towed with a Class C licence, but only if the towing vehicle is rated for that weight.
- Exceeding the manufacturer’s towing capacity can lead to legal penalties, mechanical damage, and increased safety risks.
Additional Licence Classes for Heavier Loads
- A Light Rigid (LR), Medium Rigid (MR), or Heavy Rigid (HR) licence is needed to tow over 4.5 tonnes.
- If towing a commercial load, you must follow the towing regulations NSW.
Always check your vehicle’s compliance plate before towing a caravan or heavy trailer.

Vehicle and Trailer Compliance
Before towing in NSW, it’s essential to ensure that both the towing vehicle and trailer meet all legal and safety requirements. Non-compliance can lead to fines, roadworthiness issues, and increased accident risks.
Pre-Towing Safety Checks
Before setting off, conduct a thorough inspection of your vehicle and trailer to ensure they are roadworthy and comply with NSW regulations:
- Check that lights, indicators, and brakes are fully functional.
- Ensure tyres are in good condition and inflated to the correct pressure.
- Verify that the tow hitch and safety chains are properly secured.
What is ATM vs GTM vs Tare?
Understanding weight classifications is crucial when calculating your towing capacity:
- Aggregate Trailer Mass (ATM): The total weight of a fully loaded trailer when detached from the towing vehicle.
- Gross Trailer Mass (GTM): The weight of a fully loaded trailer when it is attached to a towing vehicle.
- Tare Weight: The weight of the empty trailer without any cargo or load.
Vehicle Suitability and Towing Capacity
- The towing vehicle must have a suitable pulling capacity.
- Ensure it meets the legal aggregate trailer mass limits.
Choosing the Right Towing Equipment
- Trailers over 750 kg ATM require brakes.
- Safety chains must match the towing capacity.
- A weight distribution hitch helps reduce instability when towing a caravan.
Staying compliant with towing laws NSW ensures safer journeys.
Load and Safety Regulations
Securing your load correctly is not just a safety precaution—it’s the law in NSW. Improperly restrained loads can shift, cause accidents, or lead to heavy fines if they don’t meet the required standards. Whether towing a trailer, caravan, or heavy cargo, you must ensure your load is properly distributed and secured.
How Do You Calculate What You Can Tow?
Determining your legal towing capacity requires checking both the towing vehicle and trailer specifications. Here’s what to consider:
- Towing Capacity: Your vehicle’s maximum towing limit stated by the manufacturer.
- Gross Combination Mass (GCM): The total allowed weight of both the towing vehicle and trailer combined.
- ATM vs GTM vs Tare Weight: Make sure the fully loaded trailer does not exceed GTM limits when attached to the vehicle.
Load Security Requirements
The NSW Road Transport (General) Regulation 2013 states that all loads must be secured to prevent movement during transport:
- Heavy loads must be tied down using rated straps, chains, or restraints.
- Any overhanging cargo must be clearly marked with flags or reflective indicators.
- Loose items must be contained inside fully enclosed trailers or secured with tarpaulins and netting.
Weight Distribution and Stability
An unbalanced trailer can lead to swaying, braking issues, and poor handling. To improve stability:
- Place heavier items low and near the trailer’s axle.
- Avoid loading too much weight at the front or rear of the trailer.
- Use a weight distribution hitch for better control when towing heavy loads.
Complying with these load and safety regulations ensures a smoother, safer towing experience and helps prevent fines or accidents on NSW roads.
Safe Driving Practices for Towing

Towing a trailer, caravan, or heavy load requires adjustments to your driving technique to maintain stability, control, and safety on NSW roads. Sudden movements, improper braking, or failing to adjust for extra weight can lead to dangerous situations, accidents, or legal penalties.
Handling and Stability on the Road
- Reduce speed when towing, as extra weight increases stopping distance and affects handling.
- Allow extra space between your vehicle and the one ahead to compensate for longer braking times.
- Take wider turns, as trailers track inside the path of the towing vehicle.
- Use smooth and controlled steering to avoid trailer sway, especially in windy conditions or when overtaking.
Braking and Reversing with a Trailer
- Avoid sudden braking, which can cause the trailer to push the towing vehicle forward.
- When reversing, use small steering adjustments to control the towing trailer.
Speed Limits and Legal Restrictions
- In NSW, the maximum speed when towing is 100 km/h, even if the road’s posted limit is higher.
- Caravans and trailers must not cause excessive swaying or affect the stability of other vehicles.
- It is illegal to carry passengers inside a moving trailer or caravan.
By following these safe driving practices, you can tow confidently while reducing risks on the road.
NSW Legal Compliance and Safety Standards
Towing in NSW comes with strict legal obligations, and failing to comply with these regulations can result in fines, licence penalties, and vehicle defect notices. Understanding the legal requirements ensures you stay compliant and avoid unnecessary risks.
Trailer Laws and Registration Requirements
All trailers in NSW must be registered and display a number plate that matches the towing vehicle. For trailers over 750 kg ATM, an independent braking system is required to ensure safe stopping power. Additionally, lights, indicators, and reflectors must be in working condition and clearly visible at all times.
Vehicle Towing Authorisation and Legal Implications
A vehicle can only be towed with the owner’s consent, except in specific circumstances. If a vehicle is obstructing traffic, authorities may order it to be moved. Vehicles can also be impounded due to legal violations or recovered after an accident. Any unauthorised towing could lead to legal consequences, including theft charges.
Fines and Penalties for Non-Compliance
