8.1 Negligence, Torts, and Legal Liability
Key Takeaways
- Negligence requires all FOUR elements — duty, breach, proximate cause, and damages; remove any one and there is no liability and the insurer owes nothing.
- Liability insurance covers TORTS (civil wrongs), almost always unintentional negligence — it does not pay for crimes, contract breaches, or expected/intended injury.
- The standard of care is the 'reasonable person' — a professional is held to the higher standard of a reasonable practitioner in that field.
- Negligence per se uses violation of a statute (e.g., running a red light) as automatic proof of breach, leaving only causation and damages to prove.
- Proximate cause is the unbroken, foreseeable chain of events — an intervening cause can sever liability.
Why Liability Exists at All
Liability insurance pays sums the insured becomes legally obligated to pay as damages to a third party. So before any policy responds, a legal obligation must first exist. That obligation comes from one of three sources tested on the National P&C exam:
| Source of Liability | Description | Insurable? |
|---|---|---|
| Tort | A civil wrong (other than breach of contract) causing harm | Yes — the core of liability coverage |
| Contract | A duty voluntarily assumed by agreement | Sometimes (contractual liability coverage) |
| Statute | A duty imposed by law (e.g., workers comp, dram-shop) | Varies by line |
The overwhelming majority of liability claims are torts, and the overwhelming majority of torts are negligence. Intentional torts (assault, libel) and crimes are generally excluded because policies cover injury that is neither expected nor intended by the insured.
The Four Elements of Negligence
To win, a claimant must prove all four elements by a preponderance of the evidence. Memorize them in order — the exam loves to remove one and ask whether liability exists.
- Duty of care — a legal obligation to act as a reasonable person would.
- Breach of duty — failure to meet that standard, by act or omission.
- Proximate cause — an unbroken, reasonably foreseeable chain linking the breach to the harm.
- Damages — actual, measurable injury or loss occurred.
Trap: A driver runs a red light (breach) but no one is hurt and nothing is damaged. There are no damages, so there is no negligence and the liability policy owes nothing. A 'near miss' is never a covered claim.
The Reasonable-Person Standard
The yardstick for duty is the hypothetical reasonable, prudent person acting under the same circumstances. Key refinements:
- Professionals (doctors, agents, architects) are held to the standard of a reasonable practitioner in that profession — a higher bar. Failure here is malpractice and is covered by professional liability, not the CGL or homeowners policy.
- Children are judged against a child of like age and experience.
- Common carriers (airlines, buses) owe the highest degree of care.
Doctrines That Establish Breach
Two Latin doctrines are tested frequently:
- Negligence per se — violating a safety statute (running a stop sign, serving alcohol to a minor) is treated as automatic proof of breach. The claimant then needs only to prove causation and damages.
- Res ipsa loquitur ('the thing speaks for itself') — when an accident could not ordinarily happen without negligence and the instrumentality was in the defendant's exclusive control (a surgical sponge left inside a patient), breach is inferred and the burden shifts to the defendant to disprove it.
A landscaper carelessly leaves a rake on a client's walkway, but the homeowner notices it and steps around it without incident. Under negligence analysis, is the landscaper liable?
Proximate Cause and Intervening Causes
Proximate cause is the legally recognized cause that, in a natural and continuous sequence, produces the injury — and the injury must have been a reasonably foreseeable result. A new, independent intervening cause can break the chain and relieve the original wrongdoer of liability.
Example: A mechanic negligently leaves lug nuts loose. The wheel falls off a mile later — proximate cause is intact. But if a third driver deliberately rams the car at a stoplight before the wheel ever loosens, that deliberate act is an intervening cause that breaks the chain.
Exam tip: 'Proximate' does not mean 'closest in time or distance.' It means the legally responsible, foreseeable cause.
Beyond Negligence — Other Bases of Tort Liability
Negligence is the default, but two other categories appear on the exam:
Intentional Torts
These are deliberate wrongful acts — assault, battery, false imprisonment, defamation (libel and slander), and trespass. Because liability policies cover injury that is neither expected nor intended by the insured, intentional torts are usually excluded under Coverage A. Some, however, are picked up as named offenses under Coverage B (Personal & Advertising Injury), so the exam wants you to route them correctly rather than simply call them 'uninsured.'
Strict (Absolute) Liability
Strict liability imposes responsibility without any proof of fault or negligence. It applies to:
- Abnormally dangerous (ultrahazardous) activities — blasting, storing explosives, keeping wild animals.
- Defective products — a manufacturer is liable for a dangerous product regardless of how careful it was (products-completed operations exposure).
- Statutory schemes — workers compensation and many dram-shop laws impose liability automatically.
Trap: Under strict liability the claimant does not prove duty, breach, or even carelessness — only that the activity/product caused the harm. Defenses like 'we used reasonable care' do not help the defendant.
Putting It Together — Why This Matters to the Policy
The liability policy is silent until a legal obligation is fixed. So the claims process mirrors the tort analysis: the adjuster asks whether the insured owed a duty, breached it, caused the loss, and whether measurable damages resulted. If the claim is rooted in strict liability (a defective product), the adjuster skips the fault inquiry and focuses on causation and damages. If it is an intentional tort, the adjuster checks whether an exclusion applies or whether a Coverage B offense fits.
Knowing the source of liability — tort, contract, or statute — and the basis within tort law — negligence, intentional, or strict — tells you instantly which insuring agreement (if any) responds and which exclusions are in play. This single framework underlies almost every casualty question on the National P&C exam.
