Negligence: Elements, Defenses, and Damages

Liability coverage responds mostly to negligence claims, so the exam drills the cause of action. A plaintiff must prove four elements: a duty of care owed, breach of that duty, causation (both but-for cause in fact and proximate, foreseeable cause), and actual damages. The measuring stick for breach is the reasonable person standard — objective, not personalized. Negligence per se shortcuts part of the proof: when the defendant violates a safety statute designed to protect the plaintiff's class against the type of harm suffered, the violation conclusively establishes duty and breach — but the plaintiff must still prove causation and damages. Proximate cause carries its own famous limit: liability runs only to foreseeable plaintiffs within the zone of danger, the principle associated with Palsgraf. Defenses allocate fault to the plaintiff. Under old-style contributory negligence, any plaintiff fault — even slight — completely bars recovery; the last clear chance doctrine softens the bar by letting a contributorily negligent plaintiff recover when the defendant had the final opportunity to avoid the harm and failed to take it. Most states have moved to comparative negligence: pure comparative reduces recovery by the plaintiff's percentage of fault no matter how large, while modified comparative cuts off recovery once plaintiff fault passes a threshold (50 or 51 percent, depending on the state). Assumption of risk — express (a signed waiver) or implied (voluntarily encountering a known danger) — is a further defense. Even a plaintiff's failure to wear an available seatbelt is treated as comparative fault bearing on damages, though many states cap the reduction by statute or bar the evidence entirely. Damages come in categories the exam expects you to label. Special damages are documentable out-of-pocket economic losses — medical bills, lost wages, repair costs; general damages are non-economic losses inherent in the tort — pain and suffering, emotional distress, loss of consortium. Claim evaluators often estimate general damages with a specials multiplier of roughly 1.5 to 5 times the economic losses. Punitive damages punish egregious conduct and are constitutionally limited: under BMW v. Gore and State Farm v. Campbell, due process is measured by reprehensibility, the punitive-to-compensatory ratio, and comparable civil penalties, with few awards beyond a single-digit ratio surviving and a 4-to-1 ratio described as close to the constitutional line. Expert testimony supporting damages and causation must satisfy the reliability gatekeeping standard from Daubert.

Key rules

Negligence requires duty, breach, causation, and damages — all four.

Breach is judged against the objective reasonable person; causation includes both but-for cause and foreseeable proximate cause.

Why the exam cares: Element-spotting questions remove one element and ask whether the claim survives — it never does.

Negligence per se establishes duty and breach only.

A qualifying safety-statute violation fixes the standard of conduct and its breach, but the plaintiff must still prove causation and damages.

Why the exam cares: The exam's favorite per se trap is answers claiming the violation proves the entire case.

Contributory negligence bars recovery entirely; comparative negligence reduces it.

Pure comparative reduces damages by the plaintiff's fault share at any percentage; modified comparative bars recovery past the 50 or 51 percent threshold.

Why the exam cares: Scenario questions give a plaintiff fault percentage and ask the recovery under each regime.

Last clear chance rescues a contributorily negligent plaintiff.

When the plaintiff is helplessly in peril and the defendant thereafter had a reasonable final opportunity to avoid the harm but failed, the plaintiff may still recover.

Why the exam cares: It is tested as the recognized exception to the harsh contributory bar.

Special damages are economic and provable; general damages are non-economic.

Specials cover medical bills, lost wages, and repairs; generals cover pain and suffering and similar intangible harm, with punitive damages constitutionally capped near single-digit ratios.

Why the exam cares: Damages-classification and punitive-ratio questions both come straight from these definitions.

Numbers to memorize

  • 4 elements — duty, breach, causation, damages
  • 50% or 51% — plaintiff-fault cutoffs under modified comparative negligence
  • Under 10:1 — few punitive awards beyond a single-digit ratio satisfy due process (State Farm v. Campbell); 4:1 is near the constitutional line
  • 1.5x to 5x — typical specials multiplier for estimating general damages
  • 1–5% — statutory caps some states place on seatbelt-defense damage reductions

Common traps

  • Thinking negligence per se proves the whole claim — it establishes duty and breach only; causation and damages remain the plaintiff's burden.
  • Confusing contributory with comparative negligence — contributory is a complete bar at any plaintiff fault; comparative merely reduces recovery.
  • Mislabeling pain and suffering as special damages — specials are documentable economic losses; pain and suffering is a general damage.
  • Treating seatbelt nonuse as an absolute defense — it is comparative fault affecting damages, and states often cap or exclude the evidence.

When a fault percentage appears in the stem, immediately identify the regime — pure comparative, modified 50, modified 51, or contributory — before computing the recovery.
