Carriers liability is one of the most important — and most misunderstood — insurance covers in the road transport industry. Many operators do not have it. Others have it but do not understand what it covers. And some have it at completely inadequate limits. Here is the plain-English version.
What is carriers liability?
When you carry goods belonging to someone else as a commercial carrier, you take on legal responsibility for those goods from the moment you accept them to the moment you deliver them. If those goods are lost, stolen, or damaged while in your care, the freight owner can hold you liable.
Carriers liability insurance covers your legal liability to the freight owner for loss or damage to their goods while in your custody as a carrier. Without it, a single serious freight claim can come directly out of your business.
Consider what a consignment of pharmaceutical products worth $200,000 looks like as a claims scenario — and then consider whether your business can absorb that loss from cash flow. For most operators, the answer is no. Carriers liability is the financial protection that sits between a freight loss and a business-ending event.
The legal framework: CCLA 2017 in detail
Your liability as a carrier is governed primarily by the Contract and Commercial Law Act 2017 (CCLA). The CCLA replaced the Carriage of Goods Act 1979 and significantly updated the framework for carrier liability in this country. Understanding the different risk modes under CCLA is essential for structuring appropriate insurance.
Road carrier's risk — you are strictly liable for loss or damage to goods. Strict liability means the freight owner does not have to prove you were negligent — they just have to show the goods were damaged or lost while in your care. The burden of proof is entirely on you to show an exemption applies.
Limited carrier's risk — you are only liable for loss or damage caused by your own negligence or that of your employees. The freight owner must prove fault. In practice, legal defence costs can be substantial even when you are ultimately vindicated.
The CCLA also addresses sub-contractor chains — situations where you engage another carrier to perform part of the carriage. In this context, your liability to the principal freight owner may continue even when the sub-contractor is at fault. This is a critical issue for operations that use sub-contractors: your carriers liability insurance must cover this scenario.
Bailment law adds another layer. Even when a specific contractual framework does not apply, carriers who take possession of goods may have obligations under bailment law — the duty of care owed to a bailor by a bailee. Carriers liability insurance covers claims arising from both contractual and bailment-based liability.
Sub-contractor chains and your exposure
Many freight operations involve sub-contracting: the principal carrier accepts the freight contract and sub-contracts part or all of the actual carriage to owner-operators. The legal question — who is liable to the freight owner if the goods are lost — depends on the contract terms between the principal and the freight owner.
In many cases, the principal carrier retains primary liability to the freight owner, even if the actual loss occurred while the goods were in the sub-contractor's hands. This means the principal's carriers liability policy responds first, and the principal then has a right of recovery against the sub-contractor.
If you are a principal carrier using sub-contractors, your carriers liability policy must cover this exposure. Ask your broker specifically whether your policy covers goods in the custody of authorised sub-contractors on your behalf. If you are an owner-operator working as a sub-contractor, your own carriers liability policy protects you against claims from the principal carrier seeking recovery.
What carriers liability covers
A standard carriers liability policy covers the following.
Loss of goods — goods that go missing while in your care, including theft, misdelivery, and unexplained disappearance. Theft from a parked vehicle overnight is a common scenario, particularly in urban freight operations where vehicles are left at depots or on-street overnight.
Damage to goods — physical damage to freight caused by incidents during transport, including collision damage, crush damage from load shift, and water ingress from a vehicle leak or incident.
Emergency expenses — reasonable costs incurred to minimise loss at an incident, such as hiring additional refrigeration for temperature-sensitive cargo after a breakdown, or arranging emergency transhipment of time-critical freight.
Defence costs — legal costs of defending a claim, even if the claim is ultimately unsuccessful. These can be substantial: a contested freight claim going to arbitration or court can cost $30,000–$80,000 in legal fees regardless of outcome.
What carriers liability does not automatically cover
Refrigeration failure causing spoilage. Standard policies cover physical damage to goods, not temperature-related spoilage from reefer unit failure. Refrigerated transport operators need a specific refrigeration failure extension.
Live animal mortality. Standard carriers liability is not designed for live cargo. Livestock carriers need a specific livestock mortality extension.
Dangerous goods incidents. Some policies exclude dangerous goods without a specific endorsement. If you carry HSNO-classified substances, confirm coverage with your broker.
Consequential loss. The freight owner's downstream losses — lost production, lost sales, missed export windows — as a result of your freight failure are typically excluded from standard carriers liability. Some contracts require you to accept consequential loss liability; if yours does, discuss this with your broker.
Delay. Pure time delay (goods arriving late but undamaged) is excluded unless specifically included.
Pre-existing damage. Damage that existed before you accepted the goods. Always inspect and document cargo condition at acceptance, particularly for high-value consignments.
Inherent vice. Damage caused by the nature of the goods themselves — fresh produce that deteriorates regardless of handling. This exclusion is routinely applied to fresh food and produce claims where the carrier cannot demonstrate a specific incident caused the deterioration.
Real claim scenarios
Scenario 1: Overnight theft. A curtainsider loaded with electronics ($180,000 value) is left at a Tauranga yard overnight. By morning the curtain has been cut and the cargo removed. Carriers liability responds: the goods were in the operator's custody, the vehicle was appropriately secured, and there is no policy condition breach.
Scenario 2: Rollover damage. A refrigerated truck rolls on SH1 near Levin, damaging the load of chilled meat ($95,000 value). The motor vehicle claim covers the truck; carriers liability covers the meat loss.
Scenario 3: Contamination from sub-contractor. A milk tanker sub-contracted to an owner-operator delivers contaminated milk because the tanker was inadequately cleaned between product runs. The processor's claim is initially against the principal carrier (who sub-contracted the run). The principal's carriers liability responds, then seeks recovery from the sub-contractor's policy.
How to set the right limit
The appropriate carriers liability limit is the maximum value of freight you could carry on any single journey — with a 20% margin for charges, customs duties, and incidental costs.
For general freight operators: $250,000–$500,000 is typical. For higher-value cargo (electronics, pharmaceuticals, retail goods, high-value machinery): $1,000,000–$2,000,000. For bulk agricultural and timber loads: $100,000–$300,000 depending on commodity value.
Underinsuring your carriers liability limit is a specific risk: if you have a $250,000 limit and the claim is $350,000, you are personally responsible for the $100,000 gap. Talk to your broker about the highest-value load you could conceivably carry, and set the limit accordingly.
The bottom line
If you carry goods belonging to other people, you need carriers liability. It is as essential as the motor vehicle cover on your truck. Work with a specialist broker to set the right limit, get the right extensions for your cargo type, and make sure your policy conditions are understood by everyone who drives for you.
