15.3 Standard of Care: The Reasonable Person & Children
Key Takeaways Explain This Topic AI
The reasonable prudent person standard is objective, so a defendant's own inexperience, low intelligence, or bad judgment does not lower it.
A physical disability is taken into account, so the standard becomes that of a reasonable person with that disability.
Mental deficiency, insanity, and intoxication are not taken into account and do not reduce the standard.
A child is held to the standard of a reasonable child of like age, intelligence, and experience, a partly subjective standard, and many jurisdictions treat children under the age of about five as incapable of negligence altogether.
A child engaged in an adult or inherently dangerous activity, such as driving a car or operating a motorboat, is held to the full adult standard.

Standard of Care: The Reasonable Person & Children
Exam Snapshot: Once the court establishes that the defendant owed the plaintiff a legal duty of care, the inquiry transitions to the standard of care —the precise yardstick measuring the adequacy of the defendant's conduct. On the California FYLSE, examinees must identify which specific standard of care governs the scenario: the baseline objective Reasonable Prudent Person (RPP) standard, the tailored standard for minors, the heightened standard for professionals, or statutory standards under negligence per se. A frequent examiner trap is testing whether an actor's personal mental or intellectual infirmity excuses negligent conduct; at common law, the answer is an uncompromising no.
1. The Reasonable Prudent Person (RPP) Standard
The fundamental, default standard of care in Anglo-American tort law is the Reasonable Prudent Person under the Same or Similar Circumstances .
Purely Objective Nature
The RPP standard is completely objective . The law evaluates what a reasonably prudent, careful member of the community would have done in the actor's situation, rather than what the specific defendant subjectively believed was appropriate ( Vaughan v. Menlove , 1837):
Subjective Good Faith is Irrelevant: An actor who honestly exercises the absolute best judgment of which their personal mind is capable is still liable in negligence if their conduct falls below the community benchmark of reasonable prudence.
Clumsiness and Temperament: Chronic clumsiness, hot temper, poor judgment, or lack of worldly experience will not lower the standard. Reasonable Prudent Person Standard Adjustments
├── Mental Illness, Low IQ, Cognitive Deficits ──▶ NO ADJUSTMENT (Held to standard of person of ordinary mental stability)
├── Voluntary Intoxication ──▶ NO ADJUSTMENT (Held to standard of sober RPP)
├── Sudden Emergency (Not created by actor) ──▶ ADJUSTED CIRCUMSTANCE (RPP reacting in sudden peril without time to reflect)
- └── Physical Disability (Blindness, Paralysis) ──▶ ADJUSTED (RPP with the same physical disability)
- Mental Deficiencies & Insanity
At common law, mental illness, insanity, cognitive deficits, and low intelligence do NOT lower or alter the RPP standard ( Williams v. Hays ; Restatement (Second) of Torts § 283B ):
An adult defendant suffering from acute psychosis, severe bipolar disorder, or organic brain damage is held to the exact same standard of care as a person of ordinary mental capability and emotional stability.
Policy Rationales: (1) Between two innocent parties (the mentally impaired tortfeasor and the blameless victim), the loss should fall on the party who caused it; (2) To prevent fabricated claims of mental weakness in civil litigation; and (3) To incentivize family members, guardians, and trustees to supervise persons with severe cognitive or psychiatric impairments.
Physical Characteristics & Disabilities
In sharp contrast to mental characteristics, the law explicitly incorporates the actor's physical characteristics into the standard of care ( Restatement (Second) of Torts § 283C ):
The Standard: An actor with a permanent or temporary physical disability is held to the standard of a reasonable prudent person with the same physical disability .
Application: A blind person navigating a city sidewalk is held to the standard of a reasonable blind person using a guide dog, cane, or other tactile aids. A person confined to a wheelchair is judged by the standard of a reasonable wheelchair user under the same conditions.
Knowledge of Physical Limitations: A person with a known physical disability must act with the heightened care dictated by their condition. If a person subject to known epileptic seizures or narcoleptic blackout spells chooses to drive an automobile on a crowded freeway, the decision to operate the vehicle in the face of known physical vulnerability constitutes a direct breach of the RPP standard.
Voluntary vs. Involuntary Intoxication
Voluntary Intoxication: Voluntary consumption of alcohol or narcotics never lowers the standard of care . An intoxicated person who stumbles into an antique store or drives a motor vehicle is held to the exact standard of a reasonable, prudent, completely sober person.
Involuntary Intoxication: Involuntary intoxication (e.g., being drugged without knowledge or suffering an unforeseen, bizarre adverse reaction to a prescribed medication taken in strict accordance with a physician's directions) is treated as a sudden physical disability or external emergency circumstance.
The Sudden Emergency Doctrine
When an actor is suddenly confronted with an unexpected, perilous emergency that leaves no time for cool contemplation or deliberate choice, the actor is not held to the same standard of accuracy or perfection required in non-emergency conditions:
Standard: The actor must conduct themselves as a reasonable person would in that sudden emergency .
Bar Trap Limitation: The sudden emergency doctrine is unavailable if the actor's own prior negligence created or contributed to the emergency. A speeding motorist who encounters a washed-out bridge cannot invoke the sudden emergency doctrine to justify swerving into a crowd of pedestrians, because the driver's own antecedent speeding placed them in the crisis.
2. Standard of Care for Children
Children lack the maturity, experience, and cognitive development of adults. The law accommodates this reality by tailoring the standard of care for minors.
The General Child Standard
Under the prevailing modern rule ( Restatement (Second) of Torts § 283A ), a minor child is held to the standard of care of a reasonable child of like age, intelligence, and experience :
Subjective-Objective Synthesis: Unlike the purely objective adult RPP standard, the child standard contains pronounced subjective elements:
Age: A five-year-old is compared to other five-year-olds, not twelve-year-olds.
Intelligence: A child with advanced intellect or intellectual disabilities is evaluated against peers of comparable mental capacity.
Experience: A child raised on a farm who has operated hand tools for years is judged against a child with similar mechanical background, whereas a city child using the tool for the first time is evaluated based on their relative lack of experience.
The Traditional Common-Law "Rule of Sevens"
In traditional jurisdictions (a favorite testing framework on FYLSE multiple-choice questions), the standard of care for minors is governed by the rigid common-law Rule of Sevens :
Age Bracket Presumption of Negligence Capacity Legal Operation & Rebuttal
Under Age 7 Conclusive Presumption of Incapacity A child under seven years of age is incapable of negligence as a matter of law. No evidence of precocious intelligence can rebut this presumption.
Ages 7 to 14 Rebuttable Presumption of Incapacity The law presumes the child cannot be negligent. The burden rests on the plaintiff to prove the child possessed the maturity, discretion, and capacity to understand the risk.
Ages 14 and Older Rebuttable Presumption of Capacity The minor is presumed capable of negligence under the child standard, unless the minor proves a lack of standard developmental capacity.
The Adult Activity Exception
The protective child standard of care vanishes whenever a minor engages in an adult activity ( Robinson v. Lindsay , Wash. 1979):
The Rule: When a child engages in an activity that is inherently dangerous and normally undertaken only by adults , the child is stripped of the relaxed minor standard and is held to the full, adult Reasonable Prudent Person standard .
Covered Activities: Operating any motorized vehicle—such as an automobile, motorcycle, motorized scooter, speedboat, jet ski, snowmobile, tractor, or airplane.
Policy Rationale: When an automobile or powerboat travels down a public highway or waterway, other motorists and pedestrians cannot discern that a twelve-year-old is behind the wheel. The public safety risks are indistinguishable from those created by an adult operator. The minor must conform to the adult standard of care.
Non-Adult Activities: Riding a non-motorized bicycle, shooting an arrow at a target, playing baseball, building a treehouse, or crossing a street as a pedestrian are traditional child activities evaluated under the child standard of like age, intelligence, and experience.
