8.1 Negligence, Torts, and Legal Liability

Key Takeaways

  • Liability insurance pays only what an insured is legally obligated to pay for injury or damage to a third party — legal liability must attach first.
  • Negligence requires all four DBCD elements: Duty, Breach, Causation (actual + proximate), and Damages.
  • Absolute/strict liability imposes liability without fault for inherently dangerous activities and most product-liability claims.
  • Torts are insurable civil wrongs; crimes and (generally) punitive damages and intentional injury are not insurable as a matter of public policy.

Why Liability Concepts Drive Every P&C Exam

Liability insurance does not pay for damage to your property — it pays sums an insured becomes legally obligated to pay because of injury or damage to someone else. Before any liability policy responds, the insured must be legally liable. The national P&C exam tests the legal theory first, then the coverage forms (the ISO CGL CG 00 01 04 13, the Personal Auto Policy PP 00 01, and the Homeowners HO-3 / HO 00 03 Section II) that pay once liability attaches.

Legal liability arises three ways: (1) negligence (the vast majority of claims), (2) intentional torts, and (3) absolute (strict) liability. Almost every liability question on the exam reduces to one of these three.

Torts vs. Crimes vs. Contracts

A tort is a civil wrong (other than breach of contract) for which the law allows a remedy in the form of money damages. Liability insurance covers torts — not crimes, not contractual debts (except where a contract is specifically insured, e.g., contractual liability coverage in the CGL).

CrimeThe stateFine / imprisonmentNo (against public policy)

Trap: Punitive damages and intentional/criminal acts are commonly uninsurable as a matter of public policy in many states. The exam expects you to know liability policies cover unintentional harm and exclude expected or intended injury (the CGL and HO Section II both carry an "expected or intended" exclusion).

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. It is unintentional. To win, a plaintiff must prove all four elements:

  1. Duty — a legal obligation to exercise a standard of care toward the plaintiff.
  2. Breach — failure to meet that standard (act or omission).
  3. Causation — the breach was both the actual cause ("but for") and the proximate cause (foreseeable, unbroken chain) of the injury.
  4. Damages — actual, measurable harm occurred.

Memory aid: DBCD. If any one element fails, the negligence claim fails. Proximate cause is the most heavily tested — an intervening cause that breaks the chain (an unforeseeable third event) can relieve the defendant of liability.

Categories of Legal Liability

  • Negligence (tort) — most claims; requires DBCD.
  • Intentional torts — assault, battery, libel, slander, false arrest, invasion of privacy. Some are picked up under Personal & Advertising Injury (Coverage B of the CGL) but the "expected or intended" injury to a person remains excluded under Coverage A.
  • Absolute / strict liability — liability without fault for inherently dangerous activities (blasting, keeping wild animals, ultra-hazardous operations) and under most product liability statutes. The plaintiff need not prove negligence — only that the activity/defect caused harm.
  • Contractual liability — liability the insured assumes under a contract (e.g., a hold-harmless agreement). The CGL covers an "insured contract" as an exception to the contractual-liability exclusion.
  • Vicarious liability — liability for the acts of another (covered in 8.2).

Duty, Standard of Care, and the Reasonable Person

Negligence begins with a duty of care measured against the reasonable, prudent person standard — what an ordinarily careful person would do in like circumstances. Professionals (doctors, agents, engineers) are held to a higher professional standard of their peers. A breach is conduct falling below that standard. The exam often hides the breach in facts like a store owner ignoring a known wet floor. Remember that owing a duty and breaching it are only the first two of four elements; without damages and proximate cause, there is no recoverable negligence.

Proximate Cause and Damages

Proximate (legal) cause links the breach to the harm in an unbroken chain — the injury must be a foreseeable result of the conduct. An intervening, superseding cause can break the chain and cut off liability. The fourth element, damages, requires actual harm; near-misses with no injury are not negligence. Damages divide into special (economic: medical bills, lost wages, repair costs), general (non-economic: pain and suffering), and punitive (to punish egregious conduct). Liability policies generally pay compensatory damages but often exclude punitive damages by statute or policy language.

Negligence Per Se, Res Ipsa, and Strict Liability

Negligence per se treats violation of a safety statute (running a red light) as automatic breach. Res ipsa loquitur ('the thing speaks for itself') lets a plaintiff infer negligence when the harm would not ordinarily occur without negligence and the instrumentality was in the defendant's exclusive control — a surgical instrument left inside a patient. Strict (absolute) liability imposes responsibility without fault for abnormally dangerous activities (blasting, keeping wild animals) and defective products, so the plaintiff need not prove a breach of duty at all.

Why It Matters for Coverage

Liability policies promise to pay sums the insured becomes legally obligated to pay as damages because of bodily injury or property damage. If there is no legal liability — no negligence, no strict liability, no covered intentional tort exception — there is nothing for the policy to pay. This is why every casualty exam grounds coverage analysis in tort law first: identify the legal basis of liability, then ask whether the policy's insuring agreement and exclusions respond to that basis.
