On this record defendant was a private or contract carrier of passengers for hire.
As such he owed the plaintiff the duty to exercise ordinary care to transport his passengers safely. This general duty required him to (1) exercise ordinary care to supply a motor vehicle reasonably safe for the carriage of passengers, (2) subject his vehicle to reasonable inspection, (3) warn his passengers of nonapparent dangers involved in the use of his vehicle, including latent defects in the vehicle, of which he had actual or constructive notice, and (4) operate his motor vehicle in a careful and prudent manner and in compliance with the statutory rules of the road. 13 C.J.S. 1262, sec. 678 (d); 9 A. J. 435, sec. 10 (see cases cited in notes); 2 Torts A.L.I., sec. 392; 21 A.L.R. 2d 916.
Did defendants breach these duties which they owed the plaintiff on the day in question as a result of which plaintiff suffered the personal injuries disclosed by the record? This is the decisive question posed by this appeal. A majority of the court is constrained to answer in the negative.
The oft-repeated rules controlling the consideration of an assignment of error directed to the denial of a motion to dismiss an action as in case of nonsuit have become axiomatic. It would serve no useful purpose to repeat them here. It suffices to say we have them in mind.
We may observe, however, that defendants offered no testimony, and therefore the rule defining the extent to which the testimony of the defendant may be considered on a motion for an involuntary nonsuit has no application here.
The evidence in this case does not invoke the application of the res ipsa loquitur doctrine. We need not discuss that contention of plaintiff further than to say that plaintiff himself undertakes to point out at least two reasons why the door to the ambulance suddenly opened. Hence Etheridge v. Etheridge, 222 N.C. 616, 24 S.E. 2d 477, and the other like cases cited by him are clearly distinguishable. Rushing v. Mulhearn Funeral Home, 200 So. 52.
The plaintiff offered testimony tending to show that the extra or special dowel pin lock was in a state of bad repair, and defendants admit it was not in use on the day plaintiff was injured. Was its defective condition or nonuse the proximate cause of the mishap as alleged by plaintiff ?
Plaintiff relies upon the assertion, which he contends is a reasonable conclusion, that the defect in, or nonuse of the dowel pin lock would cause the patient compartment door to open suddenly in the event of heavy pressure on the door. This is a non sequitur. The conventional door-locking mechanism held the door closed. The automatic appliance locked it from the driver’s seat so that it could not be opened by anyone in the patient compartment.
*192Every automobile bas a regular door lock and latch, mechanism on its doors. This mechanism is provided, in part, to keep the door closed while the automobile is in motion. In addition there is provided in connection with each door lock a “push button” device which may be used to lock the door from the inside.
Such was the case on the ambulance being used by defendant at the time plaintiff received his injuries. It had on the patient compartment door a regular conventional door lock and latch mechanism such as is provided for and may be found on all Cadillac automobiles.
There is not a particle of evidence in the record tending to show that this conventional mechanism found on all Cadillac and other automobiles was defective or in a state of bad repair. Instead, all the testimony relating thereto tends to show it was not defective but adequately served the purpose for which it was intended. And it is a matter of common knowledge that it is this mechanism that keeps the door closed while a motor vehicle is in motion. Locking devices serve another purpose.
“The catches on that door are exactly the same as you’d have on a Cadillac or most any General Motors automobile. They have two catches on them. There is a groove catch and also the latch catch and the latch catch has a safety catch on it too. . . . There is no safety device other than the regular conventional Cadillac door latch. That’s all any automobile has. . . . Jar or vibration will not cause the door to come unlatched any more so than it would on a regular automobile. I’ll say there is as much chance of that door flying open from the jar as there would be on your car or my car or anybody else’s automobile . . .”
Since there was no defect in the conventional lock and latch mechanism, there was no danger created by any defect in the mechanism which held the door closed while it was in motion, notice of which had been brought home to defendant and of which he should have warned plaintiff. Anno. 21 A.L.R. 2d 916. Nor is there any evidence tending to show that the door would open when someone leaned his weight against it. Rushing v. Mulhearn Funeral Home, supra; Everett v. Evans, 207 S.W. 2d 350.
So then, it is just as reasonable to surmise that plaintiff voluntarily opened the door and threw out a cigar or cigarette butt or other waste material as it is to “infer” that plaintiff was suddenly thrown against the door, causing it to fly open. Either conclusion rests on pure speculation. Everett v. Evans, supra.
The plaintiff further insists there was a patched place in the highway; that when the ambulance passed over this place at a high rate of speed it caused a jolt or jar which either caused the door to open or threw plaintiff against it with such force as to cause it to open. This position is untenable, in the first place, for the reason there is no evidence the patched place existed on the day of the accident. In the second place, if *193we concede that it did then exist, there is no evidence tending to show that it was either elevated above or depressed below the surface of the road so as to disturb the even tenor of a motor vehicle passing over it.
Lastly, the plaintiff urges the view that the seat furnished him was small and so arranged that a man of his size seated in it had his hip pressed against the door and the door handle in such manner that the jarring and swaying of the ambulance when operated at a high rate of speed would cause his hip to slip or slide against the handle and thus open the door. This position would be quite plausible and might support an inference of negligence if the door could be opened by pressing the handle toward the rear of the ambulance. But such is not the case. Plaintiff was seated with his back to the driver’s seat, facing the rear. If a sudden jar caused him to slip down in his seat, his hip would press against the regular door lock handle. But on this record that would only tend to brace the handle and keep it from turning — this for the simple reason the handle had to be pulled forward toward plaintiff in order to open the door.
“It (the seat) is right beside the arm rest on the door. The latch (door handle) inside the door is perpendicular and when you sit in that seat the latch strikes you approximately at your hip. ... In order to move that latch you have to move your body, reach under and pull the latch toward the front of the ambulance. ... In order to reach this handle you would have to reach up under the arm rest.” And another witness testified to the same effect. “The latch is perpendicular as shown in the picture. In order to open the door the latch must be pulled forward. . . . The bottom part of the latch moves toward the front of the ambulance.”
The very multiplicity of possible reasons why the door opened, advanced by plaintiff, merely serves to emphasize the speculative nature of the testimony. There is no evidence in the record to support the inference that the accident was a natural and probable consequence of the defective condition of the automatic door-locking appliance. Just why it did open, in the light of the fact there was no defect in the regular door lock and latch mechanism, is a matter of speculation.
In effect the ease comes to this: The plaintiff alleges and proves a defect in a special locking device — not in use at the time of the accident— and was permitted to recover in the court below on the theory that the defect in, or nonuse of, this device created a special hazard, notwithstanding the testimony that the door was equipped with the conventional door lock and latch upon which all motorists rely to keep the doors closed while their vehicles are in motion, and that this mechanism was in good working order so that “you had to use the handle to open it.”
The record presents one of the tragedies of life. Plaintiff suffered grave injuries which affect his mind and from which he will not recover. *194Yet this does not warrant a judgment against the defendant unless these injuries are the proximate result of his negligence. As we read the record, there is no evidence that would warrant this conclusion.
For the reasons stated the judgment below must be
Reversed.
