This action arose out of an accident in which an automobile driven by the plaintiff, after proceeding westerly on Cutler Street in Watertown, turned left to go southerly on Main Street when it collided in the southwest quarter of the intersection with the defendant's car which he was driving easterly on Cutler Street. The material facts, most of which it is not necessary to detail here, are fully set forth in our opinion upon the first appeal in this case reported in124 Conn. 259, 199 A. 430. We there held that upon the facts found the plaintiff was negligent as a matter of law, and that the court's conclusion to the contrary was erroneous. We further observed at page 265: "Had the trial court found that although the plaintiff was negligent her negligence was not a substantial factor in bringing about her injury, it would not have barred a recovery." Incident to its decision now appealed from, the conclusions of the trial court, among others, were that: the plaintiff's failure to see the defendant's car until the moment of collision was negligence, but that this negligence upon her part was not a substantial factor in producing her injuries; the plaintiff had the right of way which the defendant failed to grant her; and the defendant's negligence was the proximate cause of the plaintiff's damage. The court accordingly rendered judgment for the plaintiff. The question determinative of this appeal is whether the court erred in rendering this judgment, implicit in *Page 11 which is the conclusion that negligence of the plaintiff was not a proximate cause of the collision.
The plaintiff contends that the essential facts found are the same on the present appeal as on the former, and that therefore the statement above quoted is authority warranting this conclusion by the trial court. Although the defendant's appeal attacks the court's finding of subordinate facts, he is entitled to no correction thereunder. It is true that the present finding states that the plaintiff looked ahead as she drove up Cutler Street before entering the intersection and saw no car, a fact not found upon the first appeal, and further that this finding recites that the defendant approached the intersection at a moderate rate of speed instead of at a fast rate as found upon that appeal. Neither these nor any other differences in the facts found upon the two appeals, however, are such as to materially affect the question of whether the plaintiff's negligence was a proximate cause of the collision. The purport of our previous decision was that the plaintiff was guilty of negligence as a matter of law, and that since the trial court's erroneous conclusion that she was at all times in the exercise of due care had eliminated from its consideration the question of her negligence as a potential proximate cause of her injury barring recovery, the defendant was entitled to a new trial to permit the determination of this issue by the court. The language of the dictum in the opinion which we have quoted, in so far as it is open to the interpretation that on the same facts found the trial court would be warranted in concluding that negligence of the plaintiff was not a substantial factor in bringing about her injury, goes beyond the ratio decidendi and is not authority for the plaintiff's claim. The question before us must be determined in accord with the legal *Page 12 principles established by repeated decisions of this court as applied to the record now before us.
The plaintiff entered the intersection at a speed of ten miles per hour, shifted to second speed, and keeping on her right side of Cutler Street, after passing to the right of the center of the intersection turned left to proceed southerly on Main Street. She then had at least half of the street which was twenty-six feet in width to travel before getting out of the intersection, and the defendant's car was at that time fifty or sixty feet west of the intersection approaching at a moderate speed. The plaintiff continuing in second speed and directing her eyes southerly instead of westerly toward the defendant's car, gave her attention to the operation of her car and proceeded on southerly until the cars collided at a point south of the center of the southwesterly quarter of the intersection. Upon these facts the probability that her continuing across would result in a collision was so clear, that the further conclusion of the court that "the plaintiff having entered the intersection and turned as aforesaid reasonably believed that it would not involve a risk of collision for her to proceed through the intersection," is unsupported by the subordinate facts and cannot stand. That aside, the belief of the operator as to the risk of a collision is not the test. The driver of a car approaching an intersection must give a car approaching it from his right "the right to cross the intersection before him, if a man of ordinary prudence in his situation, in the exercise of due care, would reasonably believe that if the two automobiles continued to run at the rate of speed at which they were then running, such continuance of their course would involve the risk of a collision." Neumann v. Apter, 95 Conn. 695, 701,112 A. 350. As we said in our opinion upon the previous appeal (p. 264), in addition to stating the *Page 13 general rule: "Where two cars approach an intersection proceeding in opposite directions and the driver of one intends to turn to his left around the center of the intersection to enter a street which crosses the one upon which he is proceeding, the risk of collision arises when he turns to enter that street. If at that time a car is approaching from the opposite direction under circumstances which to a reasonable man would indicate the danger of collision, the approaching car has the right of way."
In driving her car across in front of the defendant's car as she did with no right of way in herself and in violation of the right of way of the defendant, the plaintiff was guilty of negligence. Proceeding in second gear and at a speed apparently under ten miles an hour, it is manifest that the plaintiff could have stopped within a very short space. Under these circumstances, having failed to do so and having continued on as she did until the impact, her negligence was an active cause in the production of the collision. Where a plaintiff has "continued as an active agent in producing the conditions under which his injury was received down to the time of its occurrence, . . . he is, by acts of his volition, bringing into the situation which confronts the defendant changed conditions and, in the fullest sense, co-operating with the latter in bringing about the ultimate result. In such case his conduct must be regarded as a concurring efficient cause." Nehring v. Connecticut Co., 86 Conn. 109, 121,84 A. 301. Where a plaintiff, "before entering the zone of danger [from the defendant's automobile], although . . . about to enter it, continues on toward it, each advance that he makes is a new act of negligence on his part, and if injury results through his own negligence and that of another there can be no recovery, for each must be regarded as a proximate contributor to the injury *Page 14 resulting from their concurrent negligence." Richard v. New York, N. H. H.R. Co., 104 Conn. 229,236, 132 A. 451; Correnti v. Catino, 115 Conn. 213,221, 160 A. 892. Contributory negligence of the plaintiff which continues "`down to the very moment of the accident'" is a substantial factor in producing his damage barring recovery. England v. Watkins Brothers, Inc., 122 Conn. 1, 6, 186 A. 484; Atkinson v. Molstein, 122 Conn. 611, 615, 191 A. 344. As a matter of law the plaintiff's conduct in usurping the defendant's right of way here was negligence which was a proximate cause of the collision, barring recovery upon her complaint. On the previous appeal, that the plaintiff's negligence in failing to see the defendant's car until the moment of the collision constituted negligence as a matter of law, as stated at page 265 of the opinion, afforded a sufficient basis for that decision granting a new trial. While that statement might well have gone further to include also the plaintiff's negligence in violating the right of way rule, the fact that it did not cannot restrict the scope of the present appeal. The court erred in rendering judgment for the plaintiff on the complaint.
Notwithstanding the defendant had the right of way, the court's conclusion that he was negligent is warranted upon the facts found, which are sufficient to indicate that in continuing on his course he failed to operate his car as a reasonably prudent person with the knowledge that he had the right of way would operate his car under like circumstances. Jackson v. Brown,106 Conn. 143, 146, 137 A. 725. The court did not err in rendering judgment for the plaintiff on the counterclaim.
There is error, and the case remanded to the Superior Court with direction to enter judgment for the
