We hold, then, that the principle of Thomas v. Winchester is not limited to poisons, explosives, and things of like nature, to things which in their normal operation are implements of destruction. If the nature of a thing is such that it is reasonably certain to place life and limb in peril when negligently made, it is then a thing of danger. Its nature gives warning of the consequences to be expected. If to the element of danger there is added knowledge that the thing will be used by persons other than the purchaser, and used without new tests, then, irrespective of contract, the manufacturer of this thing of danger is under a duty to make it carefully. That is as far as we are required to go for the decision of this case. There must be knowledge of a danger, not merely possible, but probable. It is possible to use almost anything in a way that will make it dangerous if defective. That is not enough to charge the manufacturer with a duty independent of his contract. Whether a given thing is dangerous may be sometimes a question for the court and sometimes a question for the jury. There must also be knowledge that in the usual course of events the danger will be shared by others than the buyer. Such knowledge may often be inferred from the nature of the transaction. But it is possible that even knowledge of the danger and of the use will not always be enough. The proximity or remoteness of the relation is a factor to be considered. We are dealing now with the liability of the manufacturer of the finished product, who puts it on the market to be used without inspection by his customers. If he is negligent, where danger is to be foreseen, a liability will follow.
We are not required at this time to say that it is legitimate to go back of the manufacturer of the finished product and hold the manufacturers of the component parts. To make their negligence a cause of imminent danger, an independent cause must often intervene; the manufacturer of the finished product must also fail in his duty of inspection. It may be that in those circumstances the negligence of the earlier members of the series is too remote to constitute, as to the ultimate user, an actionable wrong. Beven on Negligence, (3d ed.) 50, 51, 54; Wharton on Negligence, (2d ed.) § 134; Leeds v. N. Y. Tel. Co., 178 N. Y. 118, 70 N. E. 219; Sweet v. Perkins, 196 N. Y. 482, 90 N. E. 50; Hayes v. Hyde Park, 153 Mass. 514, 516, 27 N. E. 522, 12 L. R. A. 249. We leave that question open. We shall have to deal with it when it arises. The difficulty which it suggests is not present in this case. There is here no break in the chain of cause and effect. In such circumstances, the presence of a known danger, attendant upon a known use, makes vigilance a duty. We have put aside the notion that the duty to safeguard life and limb, when the consequences of negligence may be foreseen, grows out of contract and nothing else. We have put the source of the obligation where it ought to be. We have put its source in the law.
From this survey of the decisions, there thus emerges a definition of the duty of a manufacturer which enables us to measure this defendant’s liability. Beyond all question, the nature of an automobile gives warning of probable danger if its construction is defective. This automobile was designed to go 50 miles an hour. Unless its wheels were sound and strong, injury was almost certain. It was as much a thing of danger as a defective engine for a railroad. The defendant knew the danger. It knew also that the car would be used by persons other than the buyer. This was apparent from its size; there were seats for three persons. It was apparent also from the fact that the buyer was a dealer in cars, who bought to resell. The maker of this car supplied it for the use of purchasers from the dealer just as plainly as the contractor in Devlin v. Smith supplied the scaffold for use by the servants of the owner. The dealer was indeed the one person of whom it might be said with some approach to certainty that by him the car would not be used. Yet the defendant would have us say that he was the one person whom it was under a legal duty to protect. The law does not lead us to so inconsequent a conclusion. Precedents drawn from the days of travel by stage-coach do not fit the conditions of travel to-day. The principle that the danger must be imminent does not change, but the things subject to the principle do change. They are whatever the needs of life in a developing civilization requires them to be.
In reaching this conclusion, we do not ignore the decisions to the contrary in other jurisdictions. It was held in Cadillac Co. v. Johnson, 221 Fed. 801, 137 C. C. A. 279, L. R. A. 1915E, 287, that an automobile is not within the rule of Thomas v. Winchester. There was, however, a vigorous dissent. Opposed to that decision is one of the Court of Appeals of Kentucky. Olds Motor Works v. Shaffer, 145 Ky. 616, 140 S. W. 1047, 37 L. R. A. (N. S.) 560, Ann. Cas. 1913B, 689. The earlier cases are summarized by Judge Sanborn in Huset v. J. I. Case Threshing Machine Co., 120 Fed. 865, 57 C. C. A. 237, 61 L. R. A. 303. Some of them, at first sight inconsistent with our conclusion, may be reconciled upon the ground that the negligence was too remote, and that another cause had intervened. But even when they cannot be reconciled the difference is rather in the application of the principle than in the principle itself. Judge Sanborn says, for example, that the contractor who builds a bridge, or the manufacturer who builds a car, cannot ordinarily foresee injury to other persons than the owner as the probable result. 120 Fed. 865, at page 867, 57 C. C. A. 237, at page 239, 61 L. R. A. 303. We take a different view. We think that injury to others is to be foreseen not merely as a possible, but as an almost inevitable result. See the trenchant criticism in Bohlen, supra, at page 351. Indeed, Judge Sanborn concedes that his view is not to be reconciled with our decision in Devlin v. Smith, supra. The doctrine of that decision has now become the settled law of this state, and we have no desire to depart from it.
In England the limits of the rule are still unsettled. Winterbottom v. Wright, 10 M. & W. 109, is often cited. The defendant undertook to provide a mail coach to carry the mail bags. The coach broke down from latent defects in its construction. The defendant, however, was not the manufacturer. The court held that he was not liable for injuries to a passenger. The case was decided on a demurrer to the declaration. Lord Esher points out in Heaven v. Pender, supra, at page 513, that the form of the declaration was subject to criticism. It did not fairly suggest the existence of a duty aside from the special contract which was the plaintiff’s main reliance. See the criticism of Winterbottom v. Wright, in Bohlen, supra, at pages 281, 283. At all events, in Heaven v. Pender, supra, the defendant, a dock owner, who put up a staging outside a ship, was held liable to the servants of the shipowner. In Elliot v. Hall, 15 Q. B. D. 315, the defendant sent out a defective truck laden with goods which he had sold. The buyer’s servants unloaded it, and were injured because of the defects. It was held that the defendant was under a duty “not to be guilty of negligence with regard to the state and condition of the truck.” There seems to have been a return to the doctrine of Winterbottom v. Wright in Earl v. Lubbock, [1905] 1 K. B. 253. In that case, however, as in the earlier one, the defendant was not the manufacturer. He had merely made a contract to keep the van in repair. A later case (White v. Steadman, [1913] 3 K. B. 340, 348) emphasizes that element. A livery stable keeper who sent out a vicious horse was held liable, not merely to his customer, but also to another occupant of the carriage, and Thomas v. Winchester was cited and followed, White v. Steadman, supra, at pages 348, 349. It was again cited and followed in Dominion Natural Gas Co. v. Collins, [1909] A. C. 640, 646. From these cases a consistent principle is with difficulty extracted. The English courts, however, agree with ours in holding that one who invites another to make use of an appliance is bound to the exercise of reasonable care. Caledonian Ry. Co. v. Mulholland, [1898] A. C. 216, 227; Indermaur v. Dames, L. R. 1 C. P. 274. That at bottom is the underlying principle of Devlin v. Smith. The contractor who builds the scaffold invites the owner’s workmen to use it. The manufacturer who sells the automobile to the retail dealer invites the dealer’s customers to use it. The invitation is addressed in the one case to determinate persons and in the other to an indeterminate class, but in each case it is equally plain, and in each its consequences must be the same.
There is nothing anomalous in a rule which imposes upon A., who has contracted with B., a duty to C. and D. and others according as he knows or does not know that the subject-matter of the contract is intended for their use. We may find an analogy in the law which measures the liability of landlords. If A. leases to B. a tumble-down house, he is not liable, in the absence of fraud, to B.’s guests who enter it and are injured. This is because B. is then under the duty to repair it, the lessor has the right to suppose that he will fulfill that duty, and, if he omits to do so, his guests must look to him. Bohlen, supra, at page 276. But if A. leases a building to be used by the lessee at once as a place of public entertainment, the rule is different. There injury to persons other than the lessee is to be foreseen, and foresight of the consequences involves the creation of a duty. Junkermann v. Tilyou R. Co., 213 N. Y. 404, 108 N. E. 190, L. R. A. 1915F, 700, and cases there cited.
In this view of the defendant’s liability there is nothing inconsistent with the theory of liability on which the case was tried. It is true that the court told the jury that “an automobile is not an inherently dangerous vehicle.” The meaning, however, is made plain by the context. The meaning is that danger is not to be expected when the vehicle is well constructed. The court left it to the jury to say whether the defendant ought to have foreseen that the car, if negligently constructed, would become “imminently dangerous.” Subtle distinctions are drawn by the defendant between things inherently dangerous and things imminently dangerous, but the case does not turn upon these verbal niceties. If danger was to be expected as reasonably certain, there was a duty of vigilance, and this whether you call the danger inherent or imminent. In varying forms that thought was put before the jury. We do not say that the court would not have been justified in ruling as a matter of law that the car was a dangerous thing. If there was any error, it was none of which the defendant can complain.
We think the defendant was not absolved from a duty of inspection because it bought the wheels from a reputable manufacturer. It was not merely a dealer in automobiles. It was a manufacturer of automobiles. It was responsible for the finished product. It was not at liberty to put the finished product on the market without subjecting the component parts to ordinary and simple tests. Richmond & Danville R. R. Co. v. Elliott, 149 U. S. 266, 272, 13 Sup. Ct. 837, 37 L. Ed. 728. Under the charge of the trial judge nothing more was required of it. The obligation to inspect must vary with the nature of the thing to be inspected. The more probable the danger the greater the need of caution.
There is little analogy between this case and Carlson v. Phoenix Bridge Co., 132 N. Y. 273, 30 N. E. 750, where the defendant bought a tool for a servant’s use. The making of tools was not the business in which the master was engaged. Reliance on the skill of the manufacturer was proper and almost inevitable. But that is not the defendant’s situation. Both by its relation to the work and by the nature of its business, it is charged with a stricter duty.
Other rulings complained of have been considered, but no error has been found in them.
