What Is CTP Insurance: Coverage, Claims, and Registration

Compulsory Third Party insurance, usually shortened to CTP, is mandatory motor vehicle cover that pays for injuries to people hurt or killed in a crash involving your car. Every vehicle owner must hold a CTP policy to register a vehicle, and the policy responds when someone is injured, whether that person is another driver, a passenger, a pedestrian, or a cyclist. What CTP does not do is pay for damage to any vehicle or property, and that gap catches a lot of drivers by surprise.¹

What CTP Pays For

CTP is built around personal injury. When someone is hurt in a motor vehicle accident, the policy pays for their hospital treatment, surgeries, ambulance transport, rehabilitation, and follow-up care such as physiotherapy. If the injured person cannot work while they recover, CTP also replaces lost income until they are back on the job.²

For more serious injuries, compensation extends further. That can include wheelchairs and other assistive equipment, home modifications to accommodate a disability, and personal care attendants for daily living. If someone dies in the accident, CTP can compensate surviving family members for funeral costs and the loss of that person’s income.²

Many CTP schemes run compensation on two tracks. Statutory benefits come through relatively quickly and cover treatment and wage replacement regardless of who caused the crash. A common law damages claim is the second track, where the injured person pursues a larger payout by proving another driver was at fault. Common law claims take longer but can include compensation for pain and suffering on top of the economic losses. Not every jurisdiction offers both tracks, and the rules for accessing each one differ.

What CTP Does Not Cover

The single biggest gap is property damage. CTP will not pay to repair your car, the other driver’s car, a fence you crashed through, or a power pole you hit.¹ Because CTP is compulsory, many drivers assume it handles everything. It does not. Property damage needs a separate policy, either third-party property damage cover or comprehensive insurance.

Certain conduct can also strip your coverage. If a driver deliberately causes a crash, is involved in illegal activity such as street racing, or is driving under the influence of drugs or alcohol, the insurer can deny the claim. When that happens the driver becomes personally responsible for every dollar of injury compensation owed to the victims. Some schemes also exclude claims linked to serious criminal driving offences.³

Who Can Claim on a CTP Policy

CTP covers a broad group. Passengers in any vehicle involved in the accident, pedestrians, cyclists, and motorcyclists can all claim under the at-fault vehicle’s policy. Coverage follows the vehicle rather than the driver, so if a friend or family member borrows your car and injures someone, your CTP policy still responds.²

Whether an at-fault driver can claim for their own injuries depends on the scheme. In no-fault schemes, anyone injured in a motor vehicle accident can lodge a claim for medical expenses and lost income no matter who caused the crash.³ In fault-based schemes, the at-fault driver is generally excluded and has to rely on private health insurance or personal resources.

No-Fault and Fault-Based Schemes

CTP runs under two different models depending on where your vehicle is registered, and the model in your jurisdiction shapes who can claim and how much they can recover.

Under a no-fault scheme, everyone injured in a motor vehicle accident can access statutory benefits for treatment and lost income regardless of who caused the crash. The at-fault driver can claim too, unless they were charged with a serious driving offence. These schemes prioritize getting injured people treated quickly rather than litigating blame.²

Under a fault-based scheme, only the person who was not at fault can claim CTP compensation. The injured person has to show the other driver was negligent before receiving benefits beyond emergency treatment. At-fault drivers in these schemes receive no CTP benefits for their own injuries.²

Some jurisdictions also apply thresholds before an injured person can bring a common law claim for pain and suffering. Minor injuries are handled entirely through statutory benefits, and only injuries above a defined severity level qualify for a lawsuit seeking additional compensation. That is the trade-off in no-fault systems: quicker access to basic benefits in exchange for restricted access to the courts.

How CTP Connects to Your Vehicle Registration

CTP and vehicle registration are linked by design. You cannot register a vehicle without an active CTP policy. In some jurisdictions this happens automatically because the CTP component is built into the registration fee and managed by a single insurer. In others you buy a CTP policy from a licensed insurer before you can complete or renew registration.²

If your registration is current, your CTP is current. The flip side is that letting registration lapse means CTP lapses too, and driving without it exposes you to personal liability for any injuries you cause. Authorities check coverage through registration databases, so an unregistered vehicle on the road is easy to spot.

How Premiums Are Calculated

CTP premiums are not the same for every driver. In jurisdictions where you can choose an insurer, the regulator sets a base price range and insurers adjust individual premiums using risk factors: your age, driving history, demerit points, and claims record.⁴

The vehicle matters too. Its age, where it is garaged, and its type all feed into the calculation. Motorcycles and commercial vehicles almost always carry higher CTP premiums than a standard passenger car because crashes involving those vehicles produce more severe injuries. Some insurers also look at whether you carry comprehensive cover on the same vehicle.⁴

In jurisdictions where CTP is bundled into registration, there is no choice of insurer, and the price is set by a single government-run or government-appointed scheme, typically as a flat or tiered charge based on vehicle class.

Filing a Claim After an Injury

If you have been injured in a motor vehicle accident, a CTP claim is how you access compensation. The general path looks like this:

Identify the correct insurer. If another driver caused the accident, you claim against their CTP insurer, not yours. The registration authority can usually tell you which insurer covers the at-fault vehicle. In single-scheme jurisdictions there is only one insurer to contact.
Notify the insurer as soon as you can. Delays complicate claims and, in some schemes, reduce benefits.
Complete a claim form with accurate details about the accident, your injuries, treatment received, and any time off work.
Undergo assessment. The insurer reviews your claim, contacts your treating doctors, and may require an independent medical examination.
Receive a liability decision. If accepted, treatment costs and wage replacement start flowing while the broader claim continues. If denied, you can dispute the decision through the relevant regulator.
Settle once your injury has stabilised. For serious or permanent injuries, a separate impairment assessment determines whether a lump sum is payable.

Time limits for lodging CTP claims vary, and delay almost always works against you. Some schemes require notification within months of the accident, and waiting too long can reduce your entitlement or bar the claim altogether. Starting the process early is the single most important thing you can do.

When the At-Fault Vehicle Is Uninsured or Unidentified

Being hit by an unregistered vehicle or a driver who flees the scene does not leave you without recourse. Most CTP schemes include a government-backed fund, often called the nominal defendant or an equivalent, that steps in to pay injury claims when the at-fault vehicle has no CTP coverage or cannot be identified. A portion of every registered vehicle’s CTP premium funds this safety net.

The rules for these claims are stricter. Time limits tend to be shorter, and you generally need to show you took reasonable steps to identify the at-fault vehicle. In hit-and-run cases where the vehicle is never identified, additional evidence about how the accident happened may be required.

How CTP Differs From Other Car Insurance

CTP is only one piece of the motor insurance picture, and confusing it with other cover is one of the most common mistakes drivers make.

CTP insurance covers injuries to people. It does not cover damage to any vehicle or property. It is compulsory.⁵
Third-party property damage insurance covers damage you cause to someone else’s vehicle or property. It does not cover your own vehicle or anyone’s injuries. It is voluntary.¹
Comprehensive insurance covers damage to your own vehicle as well as damage you cause to other people’s vehicles and property, plus theft, fire, weather damage, and vandalism. It does not cover personal injuries. It is voluntary.

A driver with only CTP has no cover for property damage at all. Rear-end another car and CTP pays for the other driver’s whiplash treatment, but the dented bumper, both cars, comes out of pocket. Adding at least third-party property damage cover alongside CTP fills that gap at modest cost, and comprehensive insurance covers the widest range of losses.
