Opinion
This certified appeal arises from an action brought by the plaintiff, Donna Winn, the administratrix of the estate of her deceased son, Glenn Winn (decedent), against the defendants, David Posades and the town of Plainville, for the wrongful death of the decedent resulting from an automobile collision at an intersection. On appeal, the plaintiff claims that the Appellate Court improperly affirmed the judgment of the trial court, which had granted the defendants’ motion for judgment of dismissal for failure to make out a prima facie case at the close of the plaintiffs case.
Winn
v.
Posades,
The Appellate Court opinion sets forth the procedural history of this case and the following evidence that was *52 presented by the plaintiff at trial. “On September 4, 1997, Posades, a member of the Plainville police department, was scheduled to work the midnight shift, from 11:45 p.m. until 7:45 a.m. He arrived at the police station at approximately 11:35 p.m. and, shortly thereafter, realized that he had left his handcuff keys at home. He set out for home in his police cruiser, traveling west on Route 372 toward the intersection with Route 177, an intersection controlled by a traffic light. As he entered that intersection, Posades, with a clear view to the south on Route 177, but an obstructed view to the north on Route 177, looked to the south. He was traveling at a speed of fifty-eight to seventy-five miles per hour in a twenty-five mile per hour zone. Meanwhile, the . . . decedent, who was traveling south on Route 177 at a speed of thirty-seven to forty-six miles per hour in a thirty-five mile per hour zone, proceeded into the intersection directly in the path of Posades’ vehicle. Posades’ vehicle struck the vehicle being driven by the . . . decedent, causing the decedent’s vehicle to flip before it settled off the road. There were no skid marks in the area. The impact injured Posades and fatally injured the . . . decedent, who died nine days after the accident. The . . . decedent never regained consciousness to explain what had happened before his death. Posades, the sole [surviving] eyewitness to the accident, testified that he recalled nothing of the accident or how it had occurred. He last remembered traveling west on Route 372 toward the intersection with Route 177.
“The plaintiff subsequently filed this action against the defendants, alleging, inter alia, that the collision in which the . . . decedent was killed was caused by Posades’ negligent and reckless operation of his vehicle. After presentation of the plaintiffs case-in-chief, the defendants filed a motion for a judgment of dismissal. The court heard arguments and granted the motion, stating: ‘I have read and reread most of the cases on *53 the topic of speed and proximate cause, and, after viewing the evidence most favorabl[y] toward the plaintiff, I have reluctantly concluded that the plaintiff has not made out a prima facie case. The plaintiff has the duty of proving the elements of the case, that includes duty, negligence, proximate cause and damages. The evidence to me, clearly, there was a duty. These were operators on the highway. They had a duty to each other. Clearly, there was damage, and clearly, in my view, there was evidence of negligence. In fact, there was evidence of recklessness. The fact that [Posades] was operating at a speed which charitably could be fifty-eight miles per hour and could have been as high as seventy-five miles per hour in an area, which based on photographs, appears to be an area of mixed commercial-residential use, an area that has a speed limit of twenty-five miles per hour. To me, there is no question that that is negligence and the jury could reasonably find that it’s recklessness. And, personally, I find it reprehensible that a police officer on duty not responding to an emergency was traveling that fast. . . . However, on balance, I simply find that there is not such evidence on the issue of proximate cause.’ ” Id., 611-13. The trial court therefore granted the defendants’ motion for judgment of dismissal and rendered judgment in favor of the defendants.
The plaintiff appealed from the judgment of the trial court to the Appellate Court, claiming that the trial court improperly had granted the defendants’ motion for judgment of dismissal. The Appellate Court affirmed the judgment of the trial court, concluding that the plaintiff had failed to present evidence of how the accident actually happened. Id., 618-19. Thereafter, we granted the plaintiffs petition for certification to appeal from the judgment of the Appellate Court, limited to the following issue: “Did the Appellate Court properly
*54
affirm the directed judgment of the trial court?”
Winn
v.
Posades,
The plaintiff claims that the Appellate Court improperly affirmed the trial court’s judgment of dismissal. Specifically, the plaintiff asserts that the Appellate Court misapplied the law regarding proximate cause, and failed to recognize that she had produced sufficient evidence to establish an unbroken sequence of events that tied the decedent’s death to Posades’ conduct. In response, the defendants contend that the Appellate Court properly affirmed the trial court’s judgment of dismissal. The defendants assert that evidence of Posades’ improper or negligent conduct in traveling at an excessive speed was not sufficient to remove the issue of proximate cause from the realm of pure speculation or guesswork, and that, therefore, the plaintiff failed to introduce sufficient evidence to establish proximate cause. We agree with the defendants, and, accordingly, we affirm the judgment of the Appellate Court.
As an initial matter, we set forth the applicable standard of review. Practice Book § 15-8 provides in relevant part: “If, on the trial of any issue of fact in a civil action tried to the court, the plaintiff has produced evidence and rested his or her cause, the defendant may move for judgment of dismissal, and the judicial authority may grant such motion, if in its opinion the plaintiff has failed to make out a prima facie case. . . ,”

“A prima facie case, in the sense in which that term is relevant to this case, is one sufficient to raise an issue to go to the trier of fact. ... In order to establish a
*55
prima facie case, the proponent must submit evidence which, if credited, is sufficient to establish the fact or facts which it is adduced to prove. ... In evaluating [the denial of] a motion to dismiss, [t]he evidence offered by the plaintiff is to be taken as true and interpreted in the light most favorable to [the plaintiff], and every reasonable inference is to be drawn in [the plaintiffs] favor.” (Citations omitted; internal quotation marks omitted.)
Thomas
v.
West Haven,
We view in the light most favorable to the plaintiff the following additional evidence, which was presented to the trial court and is relevant to the determination of whether the plaintiff had established a prima facie case of negligence or recklessness. The police officer who had performed an investigation of the accident testified that the front of the cruiser driven by Posades struck the driver’s side of the vehicle driven by the decedent at the intersection of Route 372 and Route 177, causing the decedent’s vehicle to roll over and the decedent to be ejected from his vehicle, resulting in the serious injuries that led to his death. The officer further testified that, at the time of the collision, Posades was traveling in a westerly direction on Route 372 at approximately fifty-eight to seventy-five miles per hour in a twenty-five mile per hour zone, and the decedent was traveling in a southerly direction on Route 177 at approximately thirty-seven to forty-six miles per hour in a thirty-five mile per hour zone. The evidence further indicated that Posades was looking to the left of the intersection at the time of the accident, not to the direction from which the decedent was *56 approaching. The evidence also established that the traffic light at the intersection was controlled by an electronic trigger, which was activated when motor vehicles approached the intersection from the north or south on Route 177. Posades was unable to recall how the accident happened, the decedent never regained consciousness, and there were no witnesses to the accident.
In affirming the judgment of the trial court, the Appellate Court concluded that “the plaintiff presented no evidence as to how the accident actually had happened. Even if the plaintiffs evidence tended to show that Posades was negligent or reckless in driving his police cruiser through the intersection at a speed of fifty-eight to seventy-five miles per hour in a twenty-five mile per hour zone, there was no evidence that that conduct proximately caused the collision.”
Winn
v.
Posades,
supra,
We begin our analysis with a brief review of the law of negligence. “[E]ssential elements of a cause of action in negligence are well established: duty; breach of that duty; causation; and actual injury.” (Internal quotation marks omitted.)
Jagger v. Mohawk Mountain Ski Area, Inc.,
This court has recognized that in a case involving an automobile accident, “[a] plaintiff cannot merely prove that a collision occurred and then call upon the defendant operator to come forward with evidence that the collision was not a proximate consequence of negligence on his part. Nor is it sufficient for a plaintiff to prove that a defendant operator might have been negligent in a manner which would, or might have been, a proximate cause of the collision. A plaintiff must remove the issues of negligence and proximate cause from the field of conjecture and speculation.” (Internal quotation marks omitted.)
O’Brien
v.
Cordova,
The plaintiff in the present case claims that the Appellate Court improperly applied
Wallace
v.
Waterhouse,
In
Wallace
v.
Waterhouse,
supra,
This court addressed a similar issue forty-six years later in
Palmieri
v.
Macero,
supra,
Similar to
Wallace
and
Palmieri,
the evidence presented by the plaintiff in the present case failed to establish that Posades’ conduct in operating his vehicle at a high rate of speed was the legal cause of the decedent’s injuries. It is well established that in order to demonstrate that the defendant’s conduct legally caused the decedent’s injuries, the plaintiff must prove both causation in fact and proximate cause. See
Paige
*60
v.
St. Andrew’s Roman Catholic Church Corp.,
supra,
Moreover, we must note that the record in the present case reveals that the plaintiffs counsel conceded, during her opening statement to the jury, that the decedent had consumed alcohol and smoked marijuana prior to operating his vehicle on the evening of the accident. This admission further supports the conclusion that factors other than Posades’ excessive speed, including the possibility of the decedent’s own impairment, might have caused the accident.
The plaintiff also contends that the Appellate Court improperly concluded that the present case is distinguishable from
Terminal Taxi Co.
v.
Flynn,
On appeal, this court found the evidence sufficient, stating, “[h]ere, there was evidence as to how the accident happened: [the plaintiff] testified about what he saw, and evidence of physical facts was introduced through the investigating officer. . . . [T]here is little doubt about the manner in which the accident occurred. The facts were adequate to warrant the jury in drawing the inference that [the defendant’s decedent] was the *62 responsible agent in causing his car to take the course it did. The jury could have found from the nature and the extent of the damage to the vehicles that [the defendant’s decedent] was operating his car at an excessive speed and that he was not driving at a reasonable distance apart from the [plaintiffs vehicle]. It was reasonable to infer that [the defendant’s decedent] was attempting to pass [the vehicle driven by the plaintiff] and, because the one-way traffic pattern terminated at the intersection, he accelerated the speed of his vehicle in order to complete the passing prior to entering the section of Long Wharf Drive where he would be confronted with oncoming traffic in the westerly lane.” Id., 317-18. Because the plaintiff in Terminal Taxi Co. had adduced sufficient evidence to establish the actual and proximate cause of the accident, that case is readily distinguishable from the present case.
The plaintiffs reliance on
Toomey
v. Danaher,
Despite the factual similarity in
Toomey
to the present case, the plaintiff relies, nevertheless, on the following dicta from
Toomey.
“An unreasonable rate of speed
*63
would be a speed which was not safe considering the type of road, the amount of traffic thereon, the condition of the road, and the weather conditions. It would also include the physical condition of the driver and the general condition of the vehicle. The posted speed limit is indicative of the maximum reasonable speed under optimum conditions. Exceeding the posted speed limit, if the proximate cause of the accident, would be actionable negligence.” Id., 208-209. The plaintiff asserts that the facts of the present case, namely, that Posades was traveling at an unreasonable speed established that his negligent and reckless conduct was the proximate cause of the accident. While we agree with the plaintiff that there was evidence that Posades was traveling at an unreasonable speed,
4
our inquiry does not end there. As this court recognized in
Toomey,
“[exceeding the posted speed limit,
if the proximate cause of the accident,
would be actionable negligence.” (Emphasis added.) Id. Even with the existence of evidence of unreasonable speed, the plaintiff nevertheless must demonstrate that the unreasonable speed was the proximate cause of the accident. See
Wallace
v.
Waterhouse,
supra,
The plaintiffs final claim is that public policy favors finding liability on the part of a police officer who operated a vehicle at an excessive rate of speed by recognizing that evidence of excessive speed is sufficient evidence of proximate cause. We disagree. Nothing in our ruling today suggests that the operator of a motor vehicle, including a police officer, who travels at an excessive speed will not be liable in damages for negli *64 gence or recklessness. Our conclusion today is simply that we decline to vary from our previous case law that consistently has concluded that proof of excessive speed by the operator of a motor vehicle is insufficient, standing alone, to establish legal cause. 5
The judgment of the Appellate Court is affirmed.
In this opinion the other justices concurred.
Notes
Although a motion to dismiss pursuant to Practice Book § 15-8 is not properly made in a jury trial, like the present case, the trial court acknowledged that the issue of whether the defendants’ motion properly should have been brought as a motion for a directed verdict was not dispositive because the standard for granting a motion for a directed verdict is the same as the standard for granting a motion for judgment of dismissal. We agree.
“We note that [a] motion for judgment of dismissal has replaced the former motion for nonsuit [pursuant to General Statutes § 52-210] for failure to make out a prima facie case.” (Internal quotation marks omitted.)
Jackson
v.
Water Pollution Control Authority,
We note that the plaintiff failed to present any expert testimony regarding whether Posades’ excessive rate of speed prevented him from avoiding the accident. Such evidence would have provided an evidentiary basis for a determination that Posades’ excessive rate of speed was the cause of the accident
In fact, as the trial court stated, Posades’ conduct was not only negligent, but “reprehensible . . . (Internal quotation marks omitted.)
