Plaintiff appeals on a settled statement from a judgment of nonsuit entered in an action for damages for personal injuries allegedly sustained by her in boarding one of the defendant city’s streetcars. Viewing the evidence in the light most favorable to plaintiff, disregarding all conflicting evidence and indulging in every legitimate inference which may be drawn from the evidence, as we are required to do in accordance with the settled rules applicable in testing the propriety of nonsuits
(Estate of Lances
(1932)
According to the settled statement, the plaintiff Mrs. Gray testified that on the morning of October 8, 1956, at about 5 .-30 a. m., she was waiting at Geary and Divisadero Streets in San Francisco for a streetcar going in an easterly direction. It was dark. The weather was slightly foggy and damp. The street lights were on.
A streetcar came to the loading zone and after it stopped, the plaintiff started to board it. She stepped up on the first of the steps and then onto the second one and also took hold of the upright bar on the post in the middle of the entrance to the loading platform. She then stepped on the edge of the loading platform, along the entire edge of which there was a strip of metal about four inches wide. As she stepped on the edge of the platform, she stepped on the above metal strip and her foot on the metal strip slipped from under her. “ [S]he fell and after falling she noticed that there was some moisture on that strip of metal. She was unable to complete getting on the street car and fell back into the street. . . .” The conductor assisted her to the curb.
Immediately following her fall, she looked at the bottom of her shoes but did not notice anything on her shoe. She could not say definitely whether or not there was moisture on the bottom of her left shoe. She testified that the steps of the streetcar looked damp to her and she noticed dampness on the street, although she could not say whether the dampness was quite heavy or slight.
She was taken to the emergency hospital in an ambulance. After receiving treatment, she went home in a taxi.
Priscilla Joseph, who was waiting to board the same streetcar, testified that the plaintiff stepped on the steps of the car and then on the metal strip which was along the outer edge of the loading platform; that when the plaintiff stepped on the metal strip she slipped and fell. She testified that “the metal strip looked OK to her. ’ ’
Mrs. Gray and Priscilla Joseph were the only witnesses testifying on the issue of liability. No adverse party testimony was introduced pursuant to the provisions of section 2055 of the Code of Civil Procedure.
The defendant City and County of San Francisco there *323 upon 1 made a motion for a nonsuit on the ground “that there was no evidence in support of plaintiff’s case or any evidence of negligence or lack of proрer care on the part of said defendant as a common carrier, and that the rule of res ipsa loquitur has no application to the facts of this case.” The motion was granted. Plaintiff’s subsequent motion for a new trial was denied.
Plaintiff makes several contentions on appeal which are reducible to the following: (1) That it was for the jury to determine whether the doctrine of res ipsa loquitur was applicable ; and (2) that, independent of such doctrine, there wаs sufficient evidence to make out a prima facie case of negligence for the jury. We consider them in the above order.
At the outset it is clear, from the conduct of the plaintiff manifesting an intention to board the streetcar at the loading zone and the conduct of the motorman in stopping the ear to receive her, that the relationship of passenger and carrier had been established.
(Lagomarsino
v.
Market Street Ry. Co.
(1945)
While it is well settled that an inference of negligence arises under the doctrine of res ipsa loquitur when a passenger on a common carrier is injured as the result of the
operation
of the streetcar or other vehicle involved
(Hardin
v.
San Jose City Lines, Inc.
(1953)
In the case before us, the trial court, by granting the motion for nonsuit, held in effect that as a matter of law, the doctrine was inapplicable. Stated another way, it apparently concluded, as a matter of law, that one or more of the conditions requisite for res ipsa loquitur was not present in the case. We must first decide whether such determination can be justified on any ground.
The conditions, of which we speak and on which the applicability of the doctrine depends, are, according to the classic statement, three in number : (1) The accident or injury must be of a kind which ordinarily does not occur in the absence of someone’s negligence; (2) it must be caused by an agency or instrumentality in the control of the defendant; and (3) it must not have been due to any voluntаry action or contribution on the part of the plaintiff.
(Barrera
v.
De La Torre
(1957)
With this latter thought in mind, we turn to consider the first requirement of the doctrine—that the injury or accident must be of а kind which ordinarily does not occur in the absence of negligence. We find the authorities in agreement that this requirement establishes a basis of past experience for the operation of the doctrine. It is stated for example in
Zentz
v.
Coca Cola Bottling Co., supra,
where the court reviewed a large number of California decisions on the point, that: “All of the cases hold, in effect, that it must appear, either as a matter of common experience or from evidence in the case, that the accident is of a type which probably would not happen unless someone was negligent. In the absence of such a probability there would be no basis for an inference of negligence which would serve to take the place of evidence of some specific negligent act or omission.” (39 Cal.2d at
*325
pp. 442-443.) Dean Prosser, in an exhaustive article on the subject, not only gives definition to the above requirement but also foreshadows (as we emphаsize, infra) the answer to our problem at hand: “A res ipsa loquitur case is a circumstantial evidence case which permits the jury to infer negligence from the mere occurrence of the accident itself. Its first requirement is a basis of past experience which will permit the triers of fact to conclude that such events do not ordinarily happen unless someone has been negligent.
There is no room, for that conclusion where the plaintiff has
merely tumbled down the stairs or
fallen in alighting from a stаtionary street car, since everyone knows that such accidents commonly occur without the fault of anyone unless it is the plaintiff himself
(Emphasis added.) (Prosser,
Res Ipsa Loquitur in California
(1949) 37 Cal. L. Rev. 183, 191-192.) Our inquiry, therefore, is properly directed to “the experience of the past.”
(Judson
v.
Giant Powder Co.
(1895)
We must determine whether from the facts of the instant case, the conclusion may be drawn on the basis of experience “that negligence is the most likely explanation of the accident.”
(Seneris
v.
Haas, supra,
Where a passenger falls down and is injured, while boarding or alighting from a carrier which is stationary, it cannot be said that negligence is a more probable explanation than any other. Common experience shows that people are likely to fall while boarding or alighting from streetcars, busses and other types of transportation without negligence on the part of anyone unless perhaps the passenger himself. Such accidents
do
ordinarily occur without thе fault of others. Essentially they are similar to accidents involving falling or slipping on permanently immovable premises, as for example on the aisle of a store (cf.
Vaughn
v.
Montgomery
*326
Ward & Co.
(1950)
Where, on the other hand, res ipsa loquitur has been applied against a carrier, the probability of negligence is present. In such instances the facts have shown that the accident or injury has arisen from the
movement
or
operation
of the carrier. (See
Dempsey
v.
Market Street Ry. Co., supra,
But where there is merely proof of an accident or injury occurring on the carrier, and nothing more, the probability of negligence is not inherent in the facts. Thus it is stated in
Wyatt
v.
Pacific Elec. Ry. Co.
(1909)
In
Stites
v.
Des Moines Transit Co.
(1957)
In
Capps
v.
American Airlines, Inc.
(1956)
The accident in the case before us is essentially of the same kind. It occurred while the carrier was at a standstill and did not arise out of any movement or operation of the defendant’s streetcar. Reasonable minds, viewing the facts on the basis of experience, cannot draw a conclusion of negligence as a probable explanation. As а matter of law, then, the accident is not “of a kind which ordinarily does not occur in the absence of someone’s negligence”
(Barrera
v.
De La Torre, supra,
We turn to plaintiff’s second contention, namely that, independent of res ipsa loquitur, there was sufficient evidence to make out a prima facie ease of negligence. Plaintiff claims no negligence in the operation of the street car. Her only claim appears to us to be that the defendant negligently allowed moisture to remain on the metal strip which bordered the loading platform. 3 Plaintiff argues that the evidence of such moisture was sufficient to take the case to the jury since *329 the defendant as a common carrier was required to use the utmost care and diligence for the safe carriage of its passengers. Plaintiff does not enlighten us as to exact condition of such moisture—whether dangerous or defective—, as to whether the condition was apparent, as to whether it was known or could have been known to the agents of the defendant, and all in all, does not explain just how mere proof of the moisture establishes a prima facie case of negligence. Defendant in reply, argues against a conclusion of negligence, that there is no evidence that the conductor of the street car knew or should have known of the condition. Thus the parties appear to stand in antithetical positions, the plaintiff claiming that liability attaches because of the prescribed highest degree of care, without taking into consideration the factor of notice, and the defendant claiming that liability does not attach because of lack of notice, without taking into consideration the prescribed highest degree of care. Unfortunately neither of the parties have referred us to any authorities establishing the criteria which they respectively apply.
Our clear starting point, however, is that the plaintiff’s claim of negligence is based on an alleged dangerous and defective condition. Innumerable decisions announce settled rules of law determining liability for such a physical condition in сonnection with other types of legal relationships, as for example that existing between a landowner and an invitee. In the ordinary ease, the plaintiff must show that the particular physical facts constituted a dangerous and defective condition and that the defendant had actual or constructive notice of it. (See for example,
Bridgman
v.
Safeway Stores, Inc.
(1960)
Do these rules apply where the underlying legal relationship is that of passenger and carrier, and where the carrier is held to the highest degree of care ? Our indeрendent research has failed to disclose any California decision squarely holding that in order to recover against a common carrier for negligence predicated upon a dangerous or defective condition, actual or constructive notice on the part of the carrier must be established. In
McBride
v.
Atchison, Topeka & S. F. Ry. Co., supra,
We are of the opinion that where the dangerous or defeсtive condition is not created by the affirmative act of the carrier, or its agents, actual or constructive notice of such condition by the carrier must be shown in order to impose liability on it. To hold otherwise would be, in effect, to make the carrier an insurer of the safety of the passenger, contrary to the settled principles defining the degree of its legal responsibility and holding the carrier not to be an insurer. (Civ. Code, § 2100;
McBride
v.
Atchison, Topeka & S. F. Ry. Co., supra,
Applying the foregoing rules, it appears that plaintiff testified that after falling she noticed “there was some moisture” on the metal strip of the loading platform. No evidence shows the nature of this moisture, that is, exactly what it was. Moisture can mean drops of water, condensed vapor, or a condition of dampness perceptible by some but not necessarily all of the human senses. There is no evidence thаt this moisture is anything different from the dampness and fog of the morning from which the plaintiff had just emerged. No evidence shows the extent of the moisture, whatever the moisture was. Neither by standards of measurement or by reference to other objects are we told the area over which it extended. Nor is there evidence that the moisture was on the metal strip before the plaintiff fell, much less that it was created or placed thereon by the affirmative act of the defendant’s agents. In short, it does not appear what the moisture was, how much there was, or how long it had been there.
The above evidence does not show a dangerous or defective condition. Such a conclusion would, in our opinion, be the result of impermissible speculation rather than the rational process of inference. No matter how favorably the evidence is viewed, it leaves no room for any inference that the condition was dangerous or that it wаs such that the defendant’s agents knew or should have known of its existence. There is not the slightest evidence in the record bearing on the length of time such condition existed prior to the accident so as to fix upon the carrier the responsibility of constructive notice.
We hold therefore that there was no evidence of negligence on the part of the defendant and that the motion for nonsuit was properly granted.
The judgment is affirmed.
Bray, P. J., and Tobriner, J., concurred,
Notes
Counsel for the respective parties stiрulated that the plaintiff could call her medical witness at a later time, in the event defendant’s motion for nonsuit was denied.
The persuasiveness of this case is not lessened by the use of the word “presumption” (common with the older decisions) instead of ‘‘inference ” or by the somewhat unfortunate language to the effect that ‘ ‘ the burden is thrown on the defendant.”
In her complaint, plaintiff alleges that “said street car was maintained and kept in a careless and negligent condition and manner by the defendants and as a result thereof . . . plaintiff slipped and fell. ...” However, it is also clear that plaintiff does not claim to have been injured as a result of a “dangerous or defective condition of public property” within the provisions of the Public Liability Act. (Gov. Code, $ 53051.)
The court stated: “Defendants argue (citing 10 Am.Jur., Carriers, $ 1394, p. 236) that in order to recover against a carrier for injuries sustained due to the presence of debris or other foreign substance uрon the steps of a railway car, it is essential to show knowledge, express or implied, on the part of the carrier of the existence of such a condition. No California cases on the subject have been cited, nor have any been found; however, here we need not determine the abstract question because the evidence is sufficient to sustain a finding that the cigar butt would have been discovered by the defendants’ porter if he had exercised the high degree of care imposed upon him. ’ ’ (McBride v. Atchison, Topeka S. F. Ry. Co., supra, 44 Cal.2d at pp. 118-119.)
