About this Document
A Load Restraint Plan is a critical document for any Australian business that transports goods by road. It is not just a piece of paper but a safety system that ensures your load, your vehicle, and the public are protected. This plan details exactly how you will secure cargo so it does not shift, fall, or leak while the vehicle is moving. In Australia, load restraint is governed by strict laws because poorly secured loads cause serious accidents. This guide will explain what a Load Restraint Plan is, why you need one, and how to create one that meets the National Transport Commission (NTC) standards and the Work Health and Safety (WHS) laws. You need a Load Restraint Plan whenever you carry a load that could move if not tied down properly. This applies to tradespeople with utes and trailers, owner drivers with trucks, and large logistics companies. If you carry building materials, machinery, pallets, or general cargo, you must have a system to secure it. Even if you only carry a ladder or a few tools, you need to ensure they are restrained. However, a formal written plan is essential when the load is heavy, bulky, or difficult to secure. It is also required when you are transporting dangerous goods or working in high risk environments. The law requires you to ensure your load does not dislodge from the vehicle. The primary law is the model Work Health and Safety Act 2011. This Act imposes a duty on the person conducting a business or undertaking (PCBU) to ensure, so far as is reasonably practicable, the safe transport of goods. This means the business owner must provide safe equipment, like ropes, chains and straps, and safe procedures. Drivers also have a duty under the WHS Act to take reasonable care of their own safety and the safety of others. They must use the restraints correctly. In addition to WHS laws, road transport laws apply. These are state and territory laws based on the National Road Transport Legislation. The Heavy Vehicle National Law (HVNL) applies in most states and sets out specific duties for parties in the supply chain. This includes the loading manager and the driver. The HVNL requires everyone in the chain of responsibility to ensure the safety of the transport task. The technical standard for load restraint in Australia is the National Transport Commission publication 'Load Restraint Guide 2018'. This guide is not a law itself but it provides the methods that courts and regulators use to measure compliance. If you follow the guide, you are considered to be doing everything reasonably practicable to comply with the law. The guide uses a simple principle. The restraint system must be strong enough to withstand the forces that occur when you drive. These forces include acceleration, braking, cornering and bumps. The guide states that the restraint system must withstand at least half the weight of the load pushing forwards, sideways, and backwards. It must also withstand the entire weight of the load pulling upwards. This is often called the tie down requirement. A Load Restraint Plan helps you prove you are meeting these requirements. It is a record that you have assessed the risks and chosen the right equipment. To complete a Load Restraint Plan, you must first understand your load. You need to know the weight of the load. You must know the centre of gravity. You must know if the load is slippery, rounded, or fragile. You then select your vehicle. The vehicle must be suitable for the load. The floor must be in good condition. You need anchorage points, like lashing rings or rails, that are strong enough for the job. You then choose your restraint equipment. This includes webbing straps, chains, steel wire ropes, or direct lashings. You must check the rating of the equipment. This is called the Lashing Capacity (LC). The LC is marked on the strap or chain. You calculate how many straps you need by dividing the required strength of the restraint by the LC of one strap. You must document all of this. The plan should list the vehicle details. It should list the load details. It should describe the restraint method. It should include a diagram or photo showing how the load is placed and how the straps are arranged. It should list the pre trip checks. A common mistake is relying on friction alone. Many people think a heavy item will not move if it is heavy enough. This is wrong. Friction is reduced if the load is on a wet or greasy surface or if the trailer bounces. You must always use lashings to clamp the load down to increase friction. Another mistake is using damaged equipment. Webbing straps fray and lose strength. Chains can develop cracks. You must inspect your gear every day. A common error is tying over sharp edges without protection. The strap will cut through instantly. You must use corner protectors or sleeves. Many people do not tension the straps enough. A loose strap does nothing. You must use a tensioning tool and pull it tight. Some people attach straps to weak parts of the vehicle, like the bumper or a thin rail. This can rip the rail off. You must only use rated anchorage points. Failing to cover the load is another issue. If you carry loose material like sand or gravel, you must cover it or use sides to prevent spillage. Spillages are dangerous and illegal. The legal requirements are strict. Under the WHS Act 2011, inspectors can issue improvement notices or prohibition notices if they see an unsafe load. They can fine businesses on the spot. In serious cases, where someone is hurt or killed, business owners can face criminal charges and large fines. The chain of responsibility under the HVNL means that everyone who touches the load can be held liable. This includes the person who packed the load, the person who loaded the truck, the business owner, and the driver. You cannot blame the driver alone if the business did not provide the right straps or training. To create a compliant plan, you should start with a risk assessment. Look at the route you are taking. Are there hills, winding roads or rough surfaces? Look at the weather. Rain or wind can affect how you cover the load. Write down the control measures you will use. This might be using extra straps, using a tarp, or blocking the load with chocks. Train your staff. Make sure they know how to read the Load Restraint Guide. Make sure they know how to use the tensioners correctly. Keep records. Keep your written plan in the vehicle or in the office. Keep your inspection records for your gear. If you have an incident, these records are your defence. They show you were proactive about safety. The Australian Tax Office (ATO) and ASIC do not regulate load restraint directly, but safe work practices affect your business viability. An accident can ruin your business. Insurance may not cover you if you were negligent or breaking the law. A Load Restraint Plan is part of good business management. It shows clients you are professional. It helps you organise your yard and your workflow. It saves time because you know exactly what gear you need for each job. For specific industries, there are extra rules. If you carry dangerous goods, you must follow the Australian Dangerous Goods Code. This code requires specific placards and segregation of loads. If you carry livestock, you must follow animal welfare laws. The basic principles of the Load Restraint Guide still apply. In summary, a Load Restraint Plan is a mandatory safety tool for Australian transport businesses. It is required by WHS laws and the Heavy Vehicle National Law. It ensures you meet the performance standards in the Load Restraint Guide 2018. It protects you from legal action and keeps the roads safe. You create it by assessing your load, choosing the right vehicle and equipment, and documenting your method. You avoid mistakes by training staff, inspecting gear and never relying on friction alone. By following this guide, you can build a plan that is practical, legal and effective for your business.

Vehicle and Load Details
This section captures the specific information about the transport vehicle and the cargo being carried.
Vehicle and Load Details
You must record accurate information about your vehicle and the load before you start any journey. This section creates a permanent record showing you understood the specific risks of that vehicle and load combination. Under the Heavy Vehicle National Law (HVNL) and the Chain of Responsibility laws, everyone in the supply chain must ensure safety. You cannot restrain a load properly if you do not know the exact weight, dimensions, or condition of the equipment you are using.
Vehicle Information
Start by filling in the registration number, make, and model. You must then identify the deck type. Is it a flat tray, a drop side, a tipper, or a curtain sider? The deck type dictates which restraint method is suitable. A curtain sider relies on the curtains and the load locking mechanism, while a flat tray relies entirely on lashings.
You must inspect the deck condition and write it down. Look for rust, oil, grease, or loose bolts. If the floor is slippery, standard friction load calculations will not work. You might need more lashings or rubber mats to increase friction. A slick or damaged deck is a major safety hazard. Record the condition as Good, Fair, or Poor. If it is Poor, do not load the vehicle until you fix it.
Load Information
Describe the load clearly. Write down exactly what you are carrying. Be specific. Do not just write "Building materials". Write "Concrete blocks" or "Steel beams". Different materials behave differently. A liquid load sloshes, while machinery on wheels rolls. Next, record the total weight. You must know the weight to calculate the number of lashings required. Refer to the Load Restraint Guide 2018 for the correct formula.
Measure the length, width, and height. These dimensions determine how you place the load to stay within the dimension limits. They also tell you if you need to use outriggers or specific tie-down points.
Finally, assess the load characteristics. You must check if the load is slippery, fragile, or likely to shift. Is it a square bale or a round bale? Is it palletised or loose? If the item has sharp edges, you need edge protectors to stop the lashings from cutting. If the load is top-heavy, you need extra support to prevent tipping. This assessment helps you meet the performance standards in the Load Restraint Guide 2018.
Take your time with this section. Accurate details help you choose the right gear and prevent heavy fines or accidents.
Restraint Equipment Selection
This section lists the physical gear used to secure the load and its strength ratings.
Restraint Equipment Selection
Selecting the correct gear is the first step to a safe load. Every item used to tie down a load must be strong enough for the job. You must know the strength of your equipment, understand how many pieces you need, and use protection to stop wear and tear. If you choose the wrong equipment, you risk load shift, heavy fines, and serious injury.
Required Equipment Fields
For every item in your restraint plan, record the following details.
- Equipment Type: Specify the material and design. Common options include webbing straps, steel chains, steel wire ropes, or winches.
- Lashing Capacity (LC) Rating: Enter the maximum load the equipment can handle. Look for the LC tag or stamp on the equipment. This rating is usually measured in kilograms.
- Quantity of Items: State the total number of individual pieces. This includes the number of straps, chains, or ropes required to secure the load according to your calculations.
- Protective Sleeves or Corner Protectors: Indicate if you will use sleeves, corner protectors, or abrasive guards. Note the material type, such as rubber, heavy fabric, or plastic.
Selecting Equipment for the Job
You cannot guess the strength of your tie-down gear. Under the Heavy Vehicle National Law (HVNL) and the Load Restraint Guide 2018, you are responsible for ensuring the combined strength of your restraint system is adequate. A general rule for most loads is that the total restraint capacity must be at least equal to the weight of the load. For some loads, like slippery steel or liquid containers, you need double the weight in restraint capacity.
Check the tag on every strap, chain, or binder. The Lashing Capacity (LC) tells you the maximum force that single piece of equipment can apply. Do not use equipment if the tag is missing or unreadable. Ensure the hooks and fittings match the rating of the strap or chain.
Using Protective Gear
Friction is the enemy of load restraint. Sharp edges on steel, timber, or concrete will cut through webbing and damage chains quickly. The Load Restraint Guide requires you to protect your equipment from damage. You must use corner protectors or protective sleeves on any sharp edge. A worn strap is a weak strap. If the webbing is frayed or the chain is stretched, replace it immediately. Using protective gear extends the life of your equipment and keeps the load secure on the road.
Methodology and Calculations
This section explains how the load is secured and proves it meets the strength requirements.
Restraint Method Selection Select the restraint method based on the type of load and the vehicle configuration. Use tie-down restraints to clamp the load to the deck, relying on friction to prevent movement. Use direct restraint to attach the load to specific vehicle points, blocking movement directly without relying on friction. You must record the chosen method in this section.
Lashing Angles Record the angle of each lashing component relative to the horizontal. Accurate angles are critical because the effectiveness of a restraint decreases as the angle becomes flatter. Use a protractor or an inclinometer to measure these angles on the job site. Do not estimate the angles by eye, as small errors significantly change the calculated strength values.
Strength Calculations and Rules Calculate the minimum strength requirements for each direction using the coefficients of friction specified in the guidelines. The calculations must provide a combined strength at least equal to the weight of the load multiplied by the relevant acceleration factor. You must meet or exceed the following minimum standards.
- Forward Strength: The restraint system must have a minimum strength equal to 80 percent of the weight of the load. This represents 0.8G deceleration.
- Rearward Strength: The restraint system must have a minimum strength equal to 50 percent of the weight of the load. This represents 0.5G acceleration.
- Sideways Strength: The restraint system must have a minimum strength equal to 50 percent of the weight of the load. This represents 0.5G lateral force.
- Upward Strength: The restraint system must have a minimum strength equal to 20 percent of the weight of the load. This represents a vertical lift factor to counteract bounce or air displacement.
Legislative Reference These calculations follow the performance standards outlined in the Load Restraint Guide 2018 published by the National Transport Commission. This guide provides the approved methods for ensuring safety on Australian roads. , compliance with these calculations is a legal requirement under the Heavy Vehicle National Law (HVNL) and the associated Road Transport Legislation. The road authorities in each state enforce these rules to prevent loads from falling onto the roadway. Ensure your documented figures clearly show that the total restraint strength meets or exceeds the 0.5G and 0.8G thresholds for the relevant directions.
Pre-trip Checklist
A safety list the driver must complete before driving.
Pre-trip Checklist
Before you move the vehicle, walk around and inspect the load. Use this checklist to ensure your gear is safe, legal, and ready for the road. A failed inspection can lead to fines, damage to stock, or serious accidents.
Inspection of Restraint Gear Check all webbing, chains, ropes, and steel straps for wear. Look for cuts, fraying, or rust. If the gear is damaged, do not use it. Ensure all ratratchet handles, winches, and load binders are working correctly and are not bent or cracked. Verify that any curtains, sides, or tailgates are in good condition. You must use equipment that is in good working order to meet the performance standards outlined in the Load Restraint Guide.
Tensioning and Security Confirm that you have applied enough tension to every restraint. Push on the load with your hand to see if it moves. If there is any movement, tighten the straps further. Check that all handles and locks are in the closed position. Ensure that the restraints pull directly down on the load or against the chassis to increase friction. Loose tension is a major cause of load shift.
Load Placement and Balance Look at the load from the front and rear. It must be even. Verify the placement of the cargo so the weight is distributed evenly across the axle groups. The load must be positioned so the vehicle is stable during cornering and braking. Check that the load does not exceed the vehicle's height or width limits. A load that sits too high makes the vehicle unstable and prone to rollover. Check the loading documents to ensure you are not carrying more weight than the Gross Vehicle Mass or Gross Combination Mass allows.
Securing Loose Items and Ends Inspect the front and rear of the load. You must use headboards or suitable blocking to prevent the load from shifting forward under heavy braking. Check that loose items like tools, dunnage, or tarps are tied down. Loose objects on the deck or falling from the load can hit other road users. Finally, ensure that no part of the load or restraint gear touches the ground or drags on the road surface when the vehicle is moving.
Compliance with the Heavy Vehicle National Law and the Load Restraint Guide 2018 is mandatory for all heavy vehicles. By following this checklist, you meet your duty to ensure safety on public roads.

Understanding Your Sign Off
Signing this document is not a formality. It is a legal declaration that you have inspected the load and verified it is secure for transport. Under the Heavy Vehicle National Law (HVNL) and Chain of Responsibility laws, the duty to ensure safety does not stop with the packer or the manager. As the driver, you are the final control point on the road. If you sign off on a load that is unsafe, you share the liability for any incident that follows. This includes fines, licence suspension, and criminal charges if a load comes loose and causes injury or death.
The Load Restraint Guide 2018 published by the National Transport Commission sets the standard for all heavy vehicles in Australia. This guide is not just advice. Courts and regulators use it as the benchmark to determine if you did everything reasonably practicable to secure the load. By signing here, you are confirming that the restraint system meets the performance standards in that guide. You are stating that the load will not shift, leak, or fall off the vehicle under normal driving conditions, including emergency braking or swerving.
Before you sign, you must physically check the equipment. Look for cuts, fraying, or rust on chains, straps, and ropes. Check that the tensioning devices are tight and locked. Ensure the weight of the load is evenly distributed and does not exceed the vehicle limits. If you see damaged gear or a load that moves when you push it with your hand, do not sign. You must refuse to drive the vehicle until the issue is fixed. Your signature confirms you have done this check and the load passed.
If you have any doubts about the restraint method or the condition of the vehicle, speak with your supervisor or the person in charge of loading immediately. Never rely on someone else's word that the load is safe. Your signature is your assurance that the vehicle is safe to enter the traffic network. Take your time, check the load thoroughly, and protect your livelihood.
