Master California Supreme Court held a radio station liable in negligence for a promotion that foreseeably induced reckless driving leading to a fatal crash. with this comprehensive case brief.
Weirum v. RKO General is a cornerstone California Supreme Court decision at the intersection of negligence law, third-party acts, and media promotions. The case arose out of a radio contest run by KHJ, a Los Angeles station owned by RKO General, that rewarded the first listener to physically locate a roaming disc jockey based on real-time on-air clues. In the rush to win, teenage listeners engaged in high-speed pursuit on public roads, culminating in a fatal accident involving an uninvolved motorist. The decedent’s family sued RKO, asserting that the station’s promotional scheme created an unreasonable and foreseeable risk of harm to the motoring public.
The court affirmed a jury verdict against RKO, articulating a clear rule: when a defendant’s affirmative conduct foreseeably creates an undue risk of harm, the defendant owes a duty to take reasonable care, and the negligent acts of responding third parties do not automatically break the chain of causation. Weirum also rejected a First Amendment defense, distinguishing between protected speech and liability for conduct that predictably precipitates dangerous behavior. For law students, the case is a prime vehicle for studying duty and foreseeability under Rowland v. Christian, intervening/superseding cause, and policy considerations that shape negligence doctrine.
Weirum v. RKO General, Inc., 15 Cal. 3d 40, 123 Cal. Rptr. 468, 539 P.2d 36 (Cal. 1975)
KHJ, a Los Angeles radio station owned by RKO General, conducted a summer promotional contest featuring a popular disc jockey known as “The Real Don Steele.” Throughout the day, the DJ drove around the Los Angeles area in a conspicuous vehicle while broadcasting real-time clues about his location. The station encouraged listeners—many of whom were young drivers out of school for the summer—to be the first to find him in order to win cash and an on-air appearance. As the DJ moved and clues were announced, groups of listeners trailed and raced to reach him. On the day in question, after a series of on-air prompts, multiple teenage listeners began following and maneuvering near the DJ’s car at high speeds. In the course of jockeying for position on public roads, two teenagers forced another motorist off the roadway, causing a rollover in which he was killed. The decedent’s survivors brought a wrongful death action against RKO (and the teenagers). A jury found RKO negligent and awarded damages. RKO appealed, arguing it owed no duty for the independent negligence of third parties, that any negligence was not a proximate cause due to superseding intervening acts, and that the First Amendment barred liability for the broadcasts.
Does a radio station that conducts a promotional contest encouraging listeners to rush to the location of an on-air personality owe a duty of care to the motoring public, and can it be held liable for a fatal accident caused by listeners’ foreseeable negligent driving, notwithstanding arguments of intervening/superseding cause and First Amendment protection?
Under California negligence law, one owes a duty to exercise ordinary care to avoid conduct that creates an unreasonable, foreseeable risk of harm to others (Rowland v. Christian). When a defendant’s affirmative acts foreseeably induce negligent or reckless behavior by third parties, those third-party acts are not a superseding cause that breaks the causal chain. A defendant may be held liable where its conduct is a substantial factor in bringing about harm that was reasonably foreseeable. First Amendment protections do not immunize a defendant from tort liability for the foreseeable consequences of promotional activities that function as conduct creating an undue risk of physical harm.
Yes. The broadcaster owed a duty to the motoring public not to create an undue risk of harm. The teenagers’ negligent driving was a foreseeable response to the contest and did not constitute a superseding cause. The First Amendment does not shield the station from liability for the foreseeable consequences of its promotional conduct. The judgment for the plaintiffs was affirmed.
Duty: Applying Rowland v. Christian, the court emphasized that duty turns principally on foreseeability and is informed by policy factors. KHJ’s contest predictably spurred a competitive “race” among youthful listeners on public streets. The broadcast exhortations, timed and phrased to induce haste, made it foreseeable that listeners would speed, tailgate, or otherwise drive recklessly to be first. Because the station’s affirmative conduct created this hazard, it owed a duty of reasonable care to the general motoring public. Causation and Intervening Acts: RKO argued that the teenagers’ independent negligence was an intervening, superseding cause. The court rejected this, holding that when the very risk that makes the conduct negligent—here, hurried and reckless driving by contestants—is what materializes, third-party negligence does not supersede liability. The station’s contest was a substantial factor in bringing about the fatal accident because it set the stage for the foreseeable competitive pursuit that directly resulted in the crash. Policy Factors: The Rowland factors supported imposing duty. The foreseeability of harm was high; the connection between the contest and the injury was close; moral blame attached to a profit-driven promotion that predictably endangered the public; imposing liability would incentivize safer contest design; the burden on broadcasters to avoid street-race-inducing promotions is minimal; and the risk is insurable. The court also rejected characterization of the case as one about failure to control third parties or about a special relationship; instead, it involved the station’s own affirmative creation of risk. First Amendment: The court held that tort liability here regulates conduct—not ideas or protected content—and does not impermissibly chill speech. The station was not being punished for expressing viewpoints but for orchestrating an activity that foreseeably incited dangerous real-world behavior. As with the classic example of falsely shouting fire in a crowded theater, the Constitution does not immunize speech-integrated conduct that creates unreasonable risks of physical harm. Thus, the First Amendment posed no bar to negligence liability.
Weirum is a leading case on duty, foreseeability, and intervening cause. It teaches that a defendant who affirmatively organizes or promotes conduct that foreseeably elicits dangerous responses by third parties owes a duty to foreseeable victims, and cannot escape liability by pointing to those third parties’ negligence. It also clarifies that First Amendment protections do not extend to shield tort liability for promotional schemes that predictably endanger the public. For law students, Weirum is frequently paired with Rowland v. Christian and Palsgraf to illustrate foreseeability-driven duty analysis and the limits of superseding cause.
No. The court did not base duty on any special relationship with the teenagers or the decedent. Instead, it emphasized the broadcaster’s own affirmative conduct in designing and executing a contest that foreseeably created an undue risk on public roads. Duty arose from the general obligation under Rowland v. Christian to avoid conduct that unreasonably endangers others.
Because their reckless driving was the very danger that made the contest negligent. When a defendant’s conduct foreseeably induces third parties to behave negligently, those acts do not break the chain of causation. The contest was a substantial factor in producing the harm, and the teenagers’ conduct was a foreseeable intervening—not superseding—cause.
The court held the First Amendment did not bar liability because the judgment regulated conduct, not protected expression. The broadcaster was liable for orchestrating a promotion that foreseeably incited dangerous real-world behavior, not for its ideas or viewpoints. Imposing a duty to avoid creating an undue risk on public streets is a permissible, content-neutral safety regulation.
The court highlighted: high foreseeability of harm; close causal connection; moral blame in running a profit-driven, hazard-creating promotion; deterrence of future harm through safer contest design; minimal burden on broadcasters to avoid street-race dynamics; and the availability of insurance to spread the risk.
Avoid formats that encourage time-pressured racing, pursuit, or competitive rushing in public spaces—especially on roads. Use designs that do not require driving or create incentives for haste (e.g., randomized drawings, online participation, or staggered, non-urgent participation). Provide clear, effective safeguards that do not rely solely on warnings.
Like Palsgraf, Weirum centers foreseeability, but it focuses on duty under California’s Rowland framework and on proximate cause where third-party acts are involved. It stands for the proposition that when affirmative conduct targets a foreseeable class (e.g., youthful drivers) and predictably triggers risky behavior, duty is owed to those foreseeably endangered, and intervening negligence will not supersede liability.
Weirum v. RKO General squarely holds that entities cannot externalize the risks of profit-seeking promotions that predictably trigger dangerous behavior by others. Where a promotional scheme foreseeably induces hurried or reckless driving, the law imposes a duty to design the activity to avoid creating an undue risk, and foreseeable third-party negligence will not break the causal chain.
For students and practitioners, the case is a durable illustration of duty and foreseeability analysis under Rowland, the limits of superseding cause, and the proper scope of First Amendment defenses in tort. It remains a cautionary lesson for media outlets and marketers: when your conduct foreseeably endangers the public, tort law will hold you to account.
