A driver who is unconscious cannot be careless. That is the whole of the defense, and the whole of the fight is the word in front of it: a sudden incapacity excuses a crash only when it could not have been foreseen.
Sudden incapacity. Negligence is a failure of care, and a person who has lost consciousness is exercising none, for good or ill. So when a driver is struck down at the wheel by a stroke, a seizure, a cardiac event or a faint, and the car goes where the body sends it, Texas law does not call that negligence. A Houston court of appeals stated the rule in a case where a man towing a camper suffered a stroke and his truck or its camper struck at least six vehicles: “unforeseeable loss of consciousness is a complete defense to the claim that a driver negligently caused a motor-vehicle accident” (Gomez v. Cooke), citing a Houston decision from 1965 for the point. The summary judgment disposed of the negligence claim and the negligence per se claim alike. The Blackout is the dispatch that put this entry on the Docket.
What kind of thing it is. The defense travels under an older name, unavoidable accident, which Texas defines as “an event not proximately caused by the negligence of any party to it” (Reinhart v. Young). It is not a separate question for the jury. Like the sudden emergency, it is an inferential rebuttal, a defense that “operates to rebut an essential element of the plaintiff’s case by proof of other facts” (Dillard v. Texas Electric Cooperative), and “inferential rebuttal questions shall not be submitted in the charge” (Texas Rule of Civil Procedure 277). It comes to the jury as an instruction beside the one question that matters, whose negligence caused the crash, and its purpose is “to advise the jurors, in the appropriate case, that they do not have to place blame on a party to the suit if the evidence shows that conditions beyond the party’s control caused the accident in question” (Dillard). The Supreme Court has noted that the instruction is most often used for a physical condition, “fog, snow, sleet, wet or slick pavement, or obstruction of view,” or for a very young child who cannot be negligent (Reinhart). In the Houston stroke case none of that was reached, because the driver proved unforeseeability so completely that the trial court granted summary judgment and the court of appeals affirmed it. That is the shape of the defense at its strongest: not an argument to a jury, but a record no jury is needed for.
The word that carries the weight. Everything turns on unforeseeable. The driver in that case had lived with high blood pressure for at least ten years, a known risk factor for stroke, and it did not matter. His physician had examined him eleven days before the crash, found the condition unchanged, rated his stroke risk as “minimal,” and “neither told Calvin that there was a risk of stroke nor foresaw a risk that Calvin would suffer a stroke and become incapacitated while driving.” Far from advising against the trip, the doctor “told Calvin to bring back pictures.” The plaintiff argued that the driver had never researched his own condition, and the court held that “this evidence is immaterial”: “Calvin is a layman, and determining the effect and foreseeable course of a medical condition is a matter for experts,” he “had no duty to independently research a medical condition,” and he “is not required to know more than an expert, or to foresee what his treating physician could not” (Gomez). The rule, then, is about warning. A prior episode. A diagnosis of a condition known to cause a loss of consciousness. A medication that carries that warning on its label. A physician who said not to drive, or who should have. Feeling ill before turning the key. Any one of those can be the warning, and a driver who had warning and drove anyway was not stricken out of a clear sky; a jury can find the collapse foreseeable and the accident not unavoidable, and then the case stands, with the driver’s share set the way Comparative Fault describes. Foreseeable is the altitude at which that question is asked: not whether this stroke on this road was predictable, but whether a reasonable person with this history would have seen the kind of harm coming.
The state’s own line. Texas already decides, for licensing, who is capable of driving. The Department of Public Safety “shall revoke the person’s license if the department determines that the person” “is incapable of safely operating a motor vehicle,” or “has failed to provide medical records or has failed to undergo medical or other examinations” “as required by a panel of the medical advisory board” (Transportation Code Section 521.294). That board of physicians and optometrists exists to help the department determine whether “an applicant for a driver’s license or a license holder is capable of safely operating a motor vehicle” (Health and Safety Code Section 12.092), and a Texas physician “may inform the Department of Public Safety” of a patient diagnosed with a disorder listed in the department’s rules, a release the statute makes an exception to the physician-patient privilege (Section 12.096). For a commercial driver the line is federal and written out: a person must not operate a commercial motor vehicle unless medically certified, and a driver is not physically qualified with an “established medical history or clinical diagnosis of epilepsy,” or of any other condition likely to cause a loss of consciousness or of the ability to control the vehicle (49 CFR 391.41). A trucker with that history who was certified anyway, or a carrier that kept him on the road, is not the driver in the Houston case; the warning was in the file, which is the argument Logbook makes about every record a carrier keeps, and the reason Negligent Entrustment reaches the person who handed over the keys.
Asleep is not stricken. The defense is for the driver who had no warning, and sleep gives warning. Drowsiness announces itself before it closes a driver’s eyes, and a condition that announces itself is foreseeable by the rule’s own terms, so a driver who nodded off is not a driver who was stricken; he is a driver who kept going. The state’s crash tables keep the two apart. In 2023, Texas officers tagged 8,473 units, each vehicle or pedestrian in a crash, with the factor printed as FATIGUED OR ASLEEP, 103 of them in fatal crashes, and 3,762 units with the factor printed as ILL (EXPLAIN IN NARRATIVE), 65 of them in fatal crashes (TxDOT). The first code is a finding about a choice. The second is a question the narrative is supposed to answer, and the answer decides the case.
How it is proved. Because the driver often cannot say what happened, and sometimes does not survive to say it, the proof is in the record, not the account. The medical history and the prescriptions, which say what the driver knew. The license file and, for a commercial driver, the medical certificate and the carrier’s qualification file. The autopsy or the emergency-room workup, which says whether the stroke or the cardiac event came before the impact or was caused by it, and which Inquest explains how to get. The witness in the next seat: in the Houston case it was the wife, who found him unresponsive with his hands in his lap and tried to move his foot off the gas. And the car’s own recorder: the federal standard requires an event data recorder, where the vehicle has one, to log the vehicle’s indicated speed and whether the service brake was on or off in the seconds before the event (49 CFR 563.7). A driver who braked and steered was awake, with the second and a half The Reaction describes. A car that ran on at speed, no brake, no correction, is consistent with a driver already gone. The module can be overwritten and the car can be scrapped, which is why Spoliation sends the letter in the first week, and the speed it holds is the number Delta-V is read from.
Who pays when no one was at fault. If the collapse was unforeseeable, no one was negligent, and the claim against the driver and his liability carrier ends. Uninsured and underinsured motorist coverage ends with it, because it protects insureds “who are legally entitled to recover from owners or operators of uninsured or underinsured motor vehicles” (Insurance Code Section 1952.101), and no one is legally entitled to recover for an unavoidable accident. Personal injury protection does not ask: when a policy carries it, the benefits “are payable without regard to” “the fault or nonfault of the named insured or recipient in causing or contributing to the collision” (Section 1952.155), and they cover the necessary medical, hospital and funeral expenses and the lost income incurred within three years of the accident, for the named insured, the household and the passengers (Section 1952.151). It is often the only coverage left, and it is claimed on the policy of the car the person was riding in, or on the person’s own.
Where it stops. The defense is complete, but it is narrow. It belongs to the driver whose collapse no one could have foreseen, and to no one else: not the driver who had been warned, not the one who felt it coming and kept driving, not the carrier that certified a driver its own file disqualified, not the owner who lent the car to a driver known to black out. For every one of those the question is the ordinary one, and the medical event is not the end of the case. It is the beginning of the proof.
Sudden incapacity is not a doctrine about the body. It is a doctrine about warning: whether the driver had any, and what he did with it.
