8.1 Negligence, Torts, and Legal Liability

Why Liability Concepts Dominate the National Exam

Liability insurance pays for damages an insured becomes legally obligated to pay a third party. Before any liability policy responds, legal liability must exist. The national portion of every P&C exam tests how liability arises, because the standard ISO Commercial General Liability (CGL) Coverage Form CG 00 01 and the Personal Auto Policy (PAP) PP 00 01 both promise to pay sums the insured is "legally obligated to pay as damages." No legal obligation, no coverage trigger.

Three Sources of Legal Liability

Liability can flow from three legal sources. Memorize this split — exam questions often hinge on distinguishing them.

Torts: The Core of Liability

A tort is a civil wrong, other than breach of contract, for which the law allows a remedy in damages. Torts divide into three branches:

• Negligence — unintentional failure to use reasonable care (the most common, most tested).
• Intentional torts — deliberate acts: assault, battery, libel, slander, false arrest. Note: liability policies generally exclude intentional acts, but personal injury/advertising injury coverage carves back libel and slander.
• Strict (absolute) liability — liability without fault for ultrahazardous activities (blasting, keeping wild animals) or defective products. The plaintiff need not prove negligence.

The Four Elements of Negligence (DBCD)

Negligence is the failure to exercise the degree of care a reasonably prudent person would use under similar circumstances. The plaintiff must prove all four elements — miss one and the claim fails.

1. Duty Owed

A legal obligation to conform to a standard of conduct. Duty arises from a relationship (innkeeper–guest), foreseeability of harm, or a statute (traffic code, building code).

2. Breach of Duty

Failing to meet the required standard — running a red light, leaving a wet floor unmarked, failing to repair a known hazard.

3. Proximate Cause

The breach must be the direct, unbroken cause of the harm. Two tests apply: cause in fact (the "but-for" test) and legal cause (the harm was a foreseeable result). An unforeseeable intervening cause can break the chain.

4. Damages

Actual, measurable harm — bodily injury, property damage, or economic loss. No damages, no recovery, even when duty was clearly breached.

Special Negligence Doctrines

Trap to Avoid

Students confuse proximate cause with the last cause in a sequence. Proximate cause is the cause that is legally sufficient and foreseeable — not necessarily the final event in time.

Intentional Torts, Strict Liability, and Absolute Liability

Negligence is only one branch of tort liability the exam tests. Intentional torts (assault, battery, false imprisonment, libel, slander, trespass) involve purposeful conduct and are usually excluded by liability policies through the intentional-injury exclusion. Strict (absolute) liability imposes responsibility without fault for inherently dangerous activities — blasting, keeping wild animals, defective products — and under dram shop and workers compensation statutes.

The distinction matters because liability insurance covers negligence and accidental occurrences, not intentional harm, and product liability often invokes strict liability.

Res Ipsa Loquitur and Negligence Per Se

Two doctrines shift or establish the negligence elements:

• Res ipsa loquitur ("the thing speaks for itself") — when an accident is of a type that ordinarily does not happen without negligence, the instrument was in the defendant's exclusive control, and the plaintiff did not contribute, the burden shifts to the defendant to disprove negligence. A surgical sponge left inside a patient is the classic example.
• Negligence per se — violating a safety statute (running a red light, code violation) that causes the type of harm the statute meant to prevent establishes breach of duty automatically.

Standard of Care and the Reasonable Person

Breach is measured against the reasonable person standard — what an ordinarily prudent person would do under the same circumstances. Professionals are held to the higher standard of their field (the reasonable physician, engineer, or producer), which is why professional liability/E&O exists separately from general negligence. Children are judged against children of similar age and experience, and a higher duty is owed to invitees than to licensees or trespassers in premises-liability questions.

Trap to Avoid

A liability policy responds to legal liability arising from negligence or an accidental occurrence. When a stem describes a deliberate act, expected/intended injury, or a contractual assumption of someone else's liability, analyze whether an exclusion (intentional acts) or an exception (insured-contract coverage of assumed liability) applies — coverage for negligence does not automatically extend to intentional or contractual liability.
