These principles require judgment for the defendants in the terrible circumstances of this highway-collision case. The driver of a pickup truck traveling too fast on an icy, divided interstate highway suddenly lost control, hurtled across a 42-foot-wide median, and collided with the defendant‘s 18-wheeler before the defendant had time to react. The collision killed one of the pickup‘s occupants and severely injured three others. The plaintiffs proved at trial that, if not for the
To assign legally significant causal force—that is, proximate causation to any other human factor in this accident would be to distort the tragic reality of what transpired. This awful accident happened because an out-of-control vehicle suddenly skidded across a wide median and struck the defendant‘s truck, before he had time to react, as he drove below the speed limit in his proper lane of traffic. That singular and robustly explanatory fact fully explains why the accident happened and who is responsible for the resulting injuries. Because no further explanation is reasonably necessary to substantially explain the origins of this accident or to assign responsibility for the plaintiffs’ injuries, the rule of proximate causation does not permit a factfinder to search for other, subordinate actors in the causal chain and assign liability to them. Compared to the central and defining fact about this accident‘s cause the pickup careening across a wide median into
Because our holding regarding proximate cause requires judgment for the defendants, we do not reach any other issues. The judgment of the court of appeals is reversed, and judgment is rendered in favor of the defendants.
I.
On the afternoon of December 30, 2014, Trey Salinas was driving his F-350 pickup with four passengers—Jennifer Blake and her three children—on I-20 eastbound near Odessa. That morning, the National Weather Service issued a winter weather advisory indicating that ice was likely to accumulate on the roads and cause hazardous driving conditions. The temperature dropped below freezing in Odessa around 9:30 a.m. At 2:50 p.m., the National Weather Service updated its advisory to say that freezing rain had begun and that temperatures would remain below freezing all afternoon.
Testimony from a driver behind Salinas suggested that Salinas was driving approximately 50-60 miles per hour when he lost control of his pickup at approximately 4:30 p.m. In the course of two to three seconds, Salinas‘s F-350 left I-20 eastbound, crossed the 42-foot grassy median, entered traffic on I-20 westbound, and collided with a Werner Enterprises 18-wheeler driven by Shiraz Ali. Ali was a driver in training with Werner. His trainer, Jeffrey Ackerman, was in the 18-wheeler‘s sleeper berth. Ali testified that as soon as he saw Salinas‘s truck, he
There is little question that driving conditions were hazardous on both sides of the road. In addition to the winter weather advisory, there was evidence that 18-wheelers parked off the side of the highway to get off the slick roads. There was also evidence that in the ninety minutes preceding the collision, there were several accidents—single-vehicle and multi-vehicle—on I-20 westbound and I-20 eastbound. At 3:00 p.m., a driver on I-20 westbound lost control, crossed the center median, and collided with a vehicle on I-20 eastbound approximately 4.5 miles from where Salinas and Ali collided. Also at 3:00 p.m., a driver elsewhere on I-20 westbound hit a concrete barrier. At 4:01 p.m., roughly 100 feet down I-20 westbound from that accident, another vehicle lost control and hit a concrete barrier. At 3:30 p.m., a car went off the road on I-20 eastbound. The officer responding to the 3:30 p.m. accident described the roads as “so icy I couldn‘t drive very fast or I would have gone out of control.” While that officer was responding to the 3:30 p.m. accident on I-20 eastbound, a pileup occurred on I-20 westbound. A different driver—traveling on I-20 westbound approaching the pileup—hit her brakes to avoid colliding with the stopped vehicles. In doing so, she lost control of her car, which went into the center median, rolled, and entered traffic on I-20 eastbound, where it collided with an
Neither Ali nor Ackerman checked the weather before they started the stretch of the drive on which the collision occurred. They had no knowledge of the 2:50 p.m. advisory, and at trial, Ali could not remember if he had seen the earlier advisory. Ali testified that the roads were wet but that he didn‘t need to drive any slower because the truck “handled just fine. Traction was good.” There was also evidence that Ali passed three different accidents in the hour preceding the collision. Ali testified that he did not remember seeing these accidents but would not deny that he did.
Ali‘s speed was extensively discussed at trial. From 2:41 p.m. to 4:26 p.m., the Blakes’ expert testified that Ali‘s speed averaged 60.57 miles per hour. Immediately prior to the F-350 crossing the median at 4:30 p.m., Ali was accelerating at full throttle after having slowed down. When Ali pressed the brake after spotting the F-350, the 18-wheeler was going approximately 50 miles per hour. At the time of impact, the 18-wheeler was going approximately 43-45 miles per hour.
The collision was catastrophic for the Blake family. Seven-year-old Zackery Blake was killed. Twelve-year-old Brianna Blake was rendered a permanent quadriplegic. Fourteen-year-old Nathan Blake and Jennifer Blake suffered traumatic brain injuries as well as physical injuries. Salinas was treated at a local hospital but was discharged within hours.
Jennifer Blake, individually and as next friend for Nathan Blake and as heir of Zackery Blake‘s estate, and Eldridge Moak, in his capacity as guardian of Brianna Blake‘s estate, sued Werner and Ali. Werner acknowledged that Ali was acting in the course and scope of his employment and accepted vicarious liability for his conduct.
The jury found Werner and Ali liable. It apportioned 70% of the responsibility for causing the Blakes’ injuries to Werner employees other than Ali, 14% to Ali, and 16% to Salinas. It awarded Jennifer Blake $16,500,000, Nathan Blake $5,000,000, and Brianna Blake $68,187,994. The district court rendered judgment against Werner and Ali, awarding these amounts plus court costs and interest. The Blakes settled with Salinas before trial. Werner and Ali received a credit from the settlement.
Werner and Ali appealed. They challenged: (1) the legal and factual sufficiency of the jury‘s negligence liability finding against Ali, (2) the legal and factual sufficiency of the jury‘s negligence liability findings against Werner, (3) jury charge issues, (4) apportionment
Werner and Ali petitioned for review in this Court. They argue: (1) Ali‘s negligence, if any, did not proximately cause the accident, (2) Ali owed no duty to the Blakes under these circumstances, (3) Werner
II.
A.
We first consider the defendants’ contention that Ali‘s negligence was not a proximate cause of the plaintiffs’ injuries. The requirement of proximate cause has been a foundational pillar of the common law throughout our history. As the ancient maxim instructs, ”In jure non remota causa sed proxima spectatur” (“In law, the immediate, not the remote, cause is considered“). Wichita City Lines, Inc. v. Puckett, 295 S.W.2d 894, 898 (Tex. 1956) (attributing the Latin phrase to Sir Francis Bacon (1561–1626)).
We have described proximate cause as requiring application of “a practical test, the test of common experience, to human conduct when determining legal rights and legal liability.” Hous. Lighting & Power Co. v. Brooks, 336 S.W.2d 603, 607 (Tex. 1960) (quoting City of Dallas v. Maxwell, 248 S.W. 667, 670 (Tex. Comm‘n App. 1923, holding approved, judgm‘t adopted)). Our precedents divide proximate cause into two elements: (1) cause in fact, and (2) foreseeability. Pediatrics Cool Care v. Thompson, 649 S.W.3d 152, 158 (Tex. 2022). The two elements are distinct, but they often entail overlapping considerations because they
Cause in fact has two components: (1) “but-for” causation, and (2) “substantial-factor” causation. Id. The defendant‘s negligence is the “but-for” cause of an injury if, “without the act or omission, the harm would not have occurred.” Id. (quoting Gunn v. McCoy, 554 S.W.3d 645, 658 (Tex. 2018)). But-for causation is essential to liability, but proving but-for causation alone does not establish that the defendant‘s negligence was a cause in fact of the plaintiffs injuries. “[I]t is not enough that the harm would not have occurred had the actor not been negligent.” Lear Siegler, 819 S.W.2d at 472 (quoting RESTATEMENT (SECOND) OF TORTS § 431 cmt. a). The plaintiff must also prove that “the [negligent] act or omission was a substantial factor in bringing about the injury.” Rogers v. Zanetti, 518 S.W.3d 394, 402 (Tex. 2017); see also Pediatrics, 649 S.W.3d at 158.
The slippery word “substantial” can be difficult to nail down in many contexts. But in this context, our precedents provide useful contours. We have on several occasions described the “substantial-factor” requirement with reference to the following instructive passage from the Restatement:
The word “substantial” is used to denote the fact that the defendant‘s conduct has such an effect in producing the harm as to lead reasonable men to regard it as a cause, using that word in the popular sense, in which there always lurks the idea of responsibility, rather than in the so-called “philosophic sense,” which includes every one of the great number of events without which any happening would not have occurred.
A key insight of this passage, to which we have pointed before, is that within the concept of proximate cause, there “always lurks the idea of responsibility.” Lear Siegler, 819 S.W.2d at 472; Crump, 330 S.W.3d at 224; Flores, 232 S.W.3d at 770. The requirement of proximate causation—with its subsidiary requirement of substantial-factor causation—compels inquiry into whether, given the nature of the defendant‘s causal connection to the accident, it is reasonable to conclude that he is “actually responsible for the ultimate harm.” Crump, 330 S.W.3d at 224. If, on the other hand, the defendant‘s conduct “merely creates the condition that makes the harm possible, it is not a substantial factor in causing the harm as a matter of law.” Stanfield v. Neubaum, 494 S.W.3d 90, 97 (Tex. 2016) (internal quotation omitted). In other words, “cause in fact is not established where the defendant‘s negligence does no more than furnish a condition which makes the injuries possible.” IHS, 143 S.W.3d at 799.
B.
By answering “yes” to the question about Ali‘s liability, the jury found that Ali‘s negligence was a substantial factor in bringing about the Blakes’ injuries. To overcome that finding on appeal, the defendants must demonstrate that no reasonable juror could have so found. See City of Keller v. Wilson, 168 S.W.3d 802, 823 (Tex. 2005) (“Judgment without or against a jury verdict is proper at any course of the proceedings only when the law does not allow reasonable jurors to decide
We conclude the defendants have made this demanding showing. The jury charge distinguished between but-for causation and substantial-factor causation and required the jury to find both. Given a proper understanding of substantial-factor causation—an understanding consistent with the jury charge given in this case—no reasonable juror could assign responsibility for these injuries to anyone other than the driver who lost control of his vehicle and hurtled across a 42-foot median into oncoming highway traffic, thereby causing this accident and these injuries in every legally relevant sense of the word.1
In defense of the verdict, the Blakes point to evidence that if Ali had been going fifteen miles per hour, then “[t]he pickup would have spun safely across the roadway and into the grass because there was nothing for it to hit.” They also emphasize that Ali knew that passenger vehicles are more likely than 18-wheelers to slide on ice, and he knew what the consequences of such a loss of control in front of an 18-wheeler would be. He also knew or should have known the conditions were
The court of appeals agreed. 672 S.W.3d at 578. It considered Ali‘s testimony that he knew that passenger vehicles are more likely to lose control on ice than 18-wheelers and that he knew what the consequences of a passenger vehicle losing control on an icy highway in front of an 18-wheeler would be. Id. at 577. The court of appeals also looked to both parties’ accident-reconstruction expert testimony, which indicated that if Ali had been driving fifteen miles per hour, the collision would not have happened. Id. Evaluating this evidence in the light most favorable to the jury finding, the court of appeals concluded that the evidence enabled a reasonable juror to find that Ali‘s negligence was a substantial factor in bringing about the injuries, that his negligence
We can assume sufficient evidence that Ali‘s speed—and even his presence on the icy road at all—was negligent under these weather conditions. And we can assume that Ali‘s negligent driving was a but-for cause of the injuries, in that “without [Ali‘s negligence] harm would not have occurred.” Zanetti, 518 S.W.3d at 402. The Blakes focus their defense of the verdict primarily on the abundant evidence impugning Ali‘s driving and his decisions in the hours and moments leading up to the accident. They do not fault Ali, however, for his reaction once Salinas lost control. To the contrary, their expert testified that Ali did the best he could during the two seconds preceding the crash.2 Ali‘s
Powerful as this line of argument may be in the wake of such terrible consequences for the blameless victims, it addresses only but-for causation. It does not account for the requirement of substantial-factor causation, which we conclude is lacking here as a matter of law. That is so because the sole substantial factor in bringing about this accident—the singular fact that substantially explains why the accident happened and who is responsible for the plaintiffs’ injuries—was Salinas‘s losing control of his F-350 and crossing a 42-foot grassy median into oncoming highway traffic before Ali had time to react. The Blakes are correct, of course, that there can be more than one proximate cause of an injury. Lear Siegler, 819 S.W.2d at 471. That does not mean there is always more than one proximate cause. On these facts, we hold that there was only one.
“Where the initial act of negligence was not the active and efficient cause of plaintiffs’ injuries, but merely created the condition by which the second act of negligence could occur, the resulting harm is too attenuated from the defendants’ conduct to constitute the cause in fact of plaintiffs’ injuries.” IHS, 143 S.W.3d at 799. Likewise, the
Q. Okay. So no criticisms about how fast he reacted to seeing Mr. Salinas come across?
A. No, not at all. He reacted very quickly.
Under the undisputed facts of this case, the Blakes’ injuries happened because Trey Salinas, in the course of two or three seconds, lost control of his F-350, hurtled across the median into oncoming traffic on I-20, and collided with a vehicle driving below the speed limit in its proper lane on the other side—a vehicle which, tragically for the Blakes, happened to be an 18-wheeler. Ali‘s “initial act of negligence“—whether it was his speed in icy conditions or his presence on the highway—“merely created the condition by which the second act of negligence [Salinas‘s loss of control] could” bring about the injury. Id. “[T]he resulting harm is too attenuated from [Ali‘s] conduct to constitute the cause in fact of plaintiffs’ injuries.” Id.
Nothing Ali did or didn‘t do contributed to Salinas‘s truck hitting ice, losing control, veering into the median, and entering oncoming traffic on an interstate highway. However Ali was driving, the presence of his 18-wheeler in its proper lane of traffic on the other side of I-20
Surely, as the plaintiffs urge, if Ali had been driving more slowly, Salinas would not have collided with him. Just as surely, however, if Ali had been driving 100 miles per hour, Salinas would not have collided with him. Had either driver been driving much slower or faster, this accident would not have happened as it did. See Myers v. Bright, 609 A.2d 1182, 1188 (Md. 1992) (“[H]ad [the plaintiff] been going much faster she also would have avoided the accident.“). And if no vehicle at all had been in Salinas‘s path as he crossed into oncoming traffic, the Blakes would not have been injured. On the other hand, if the vehicle in that spot had been a small car rather than an 18-wheeler, Salinas‘s F-350 could have killed or severely injured its occupants.
The position and speed of the vehicles on the other side of a broadly divided highway when an oncoming F-350 suddenly hurtles across the median toward them is precisely the kind of “happenstance of place and time” that can have enormous consequences for the victims of an accident but cannot reasonably be considered the proximate cause of the accident or the resulting injuries. As between the two drivers involved in a head-on collision, substantial-factor causation requires us
C.
The Blakes rely on our decision in Biggers v. Continental Bus System, Inc., 303 S.W.2d 359 (Tex. 1957). Biggers involved a collision between a car and a commercial bus on a rural stretch of two-lane highway eight miles north of Huntsville in 1951. Id. at 361. The road was wet with rain. Id. at 362. At the point of collision, just north of a small bridge, the highway was 24-feet wide. Id. at 361. The bus was driving at an excessive speed northward but was properly on the right side of the two-lane road. Id. at 361–62. At the same time, three passenger vehicles were traveling southward in a single line toward the bridge. Id. As they approached the bridge, the first vehicle “slowed down to observe the creek to ascertain if it was too muddy for fishing.” Id. at 362. Reacting to the first car, the second and third cars traveling behind the first car also slowed, but the third car slid into the car in front of it. Id. The contact “propelled” the second car “somewhat diagonally eastward into the bus‘[s] right-hand side of the highway,” where it collided with the bus. Id.
Biggers focuses on the foreseeability aspect of proximate cause, not on the requirement of substantial-factor causation we apply today. We determined that the possibility of such a collision was foreseeable under the circumstances:
It would be wholly out of keeping with reality to hold that an operator of an automobile traveling on a modern, heavily-traveled public highway cannot and should not, under any circumstances, reasonably foresee that an automobile approaching from the opposite direction may,
for some reason, enter the wrong traffic lane and thus be endangered by excessive speed which makes stopping, deceleration or turning aside to avoid a collision impossible or more difficult.
Biggers is legally distinguishable from our decision today in part because it primarily addresses foreseeability and but-for causation rather than focusing on the requirement of substantial-factor causation as enunciated in our more recent decisions. That is not to suggest these discrete inquiries are sealed off from one another. Just as the substantial-factor inquiry incorporates “the idea of responsibility” into the question of proximate cause, Lear Siegler, 819 S.W.2d at 472, the foreseeability inquiry likewise “addresses the proper scope of a defendant‘s legal responsibility for negligent conduct,” Zanetti, 518 S.W.3d at 402. Both inquiries involve “practical” application of the “test of common experience, to human conduct.” Brooks, 336 S.W.2d at 607 (quoting Maxwell, 248 S.W. at 670). And both inquiries serve a common purpose, which is to ask, under the banner of proximate cause, “whether a defendant‘s blameworthy act was sufficiently related to the resulting harm to warrant imposing liability for that harm on the defendant.” Exxon Co., U.S.A. v. Sofec, Inc., 517 U.S. 830, 839 (1996) (discussing proximate cause generally). Naturally, similar considerations will often bear on both substantial-factor causation and foreseeability.
The two are nevertheless distinct. Foreseeability asks “what should reasonably be anticipated in the light of common experience applied to the surrounding circumstances.” Biggers, 303 S.W.2d at 364.
Biggers is also factually distinguishable from today‘s case, primarily because it involved vehicles traveling in close proximity on a narrow, two-lane highway crossing a bridge. Applying a “practical, common sense test, the test of common experience,” Biggers rejected the defendants’ contention that, in such circumstances, the excessive speed of the vehicle traveling in its proper lane can never be a proximate cause of a collision with an oncoming car that moves unexpectedly into oncoming traffic. Biggers, 303 S.W.2d at 364.
The very same “practical, common sense test, the test of common experience” yields a different result, in our view, when applied to the modern experience of driving on a four-lane highway divided by a broad, grassy median. The vehicles in Biggers were operating in narrow quarters at a bridge crossing, sharing a two-lane road, approaching each other in close proximity. Vehicles on a divided highway, by contrast, operate on what are essentially two different roads. The possibility that a driver on a two-lane rural highway will mistakenly enter oncoming traffic, while still remote as a matter of common experience outside of designated passing zones, is vastly more likely than the possibility that a driver on a broadly divided highway will cross the median and enter oncoming traffic. Nothing in Biggers suggests we must extend its
Even in the context of two-lane highways divided only by a stripe of paint, we made clear after Biggers, in the factually similar case of Baumler v. Hazelwood, that the defendant‘s excessive speed is not necessarily a proximate cause of a collision with an oncoming driver who suddenly veers onto the wrong side of the road. See Baumler v. Hazelwood, 347 S.W.2d 560, 561 (Tex. 1961). Distinguishing Biggers, we held that liability in such circumstances “depends upon the facts.” Id. at 565. We overturned a jury verdict assigning liability to a driver who was struck when another vehicle entered his side of the road, just as we do today. Id.
A key fact, in both Baumler and Biggers, was the reaction time available to the driver traveling in his correct lane. The reaction time was just a split second in Baumler. Id. at 564. Yet in Biggers, “the car which got into the pathway of the bus got there at least 3 1/2 seconds before the collision.” Id. at 365. Indeed, as we noted in Baumler, the Court in Biggers hypothesized that if, instead of 3.5 seconds, the car had “entered the bus‘[s] lane of traffic less than two seconds before the
Both Biggers and Baumler demonstrate, as we would expect, that identifying the proximate cause of an accident on the road “depends upon the facts.” Baumler, 347 S.W.2d at 565. That does not mean, however, that a jury may always answer as it chooses, irrespective of the facts. As in Baumler, an appellate court must overturn a jury verdict if the facts in evidence, taken in the light most favorable to the verdict, do not support a reasonable theory of proximate causation. In these prior cases, as today, one key fact informing our assessment of proximate cause is the defendant driver‘s reaction time. Yet, as discussed above, the most decisive fact distinguishing this case from Biggers is the vast difference between a 24-foot-wide two-lane highway and an interstate highway divided by a 42-foot grassy median.
We are directed to just one other reported American case in which an out-of-control vehicle crossed the wide median of a modern, divided highway and the injured plaintiff sued a driver who had insufficient time to react before colliding with the errant vehicle. See Creel v. Loy,
Neither the dearth of such cases nor the outcome of the Montana case should be surprising. Head-on collisions tragically do happen. But as a “practical” matter of “common experience,” we normally would not blame the driver who stayed in his lane and was struck, before he had time to react, by an out-of-control vehicle careening unexpectedly across a wide median into oncoming traffic. Brooks, 336 S.W.2d at 607 (quoting Maxwell, 248 S.W. at 670). Even in treacherous conditions—perhaps especially in treacherous conditions—each driver has a personal responsibility to maintain control of his vehicle and to stay on his side of the road. Our shared sense that each driver on the road bears that basic responsibility is what makes modern high-speed driving possible. Every driver proceeds in unspoken reliance on other drivers maintaining control of their vehicles and staying on their side of the road. Our lives are in each other‘s hands every second we spend on a highway in the multi-ton steel projectiles we drive. In most cases, we
That general rule may be subject to some variance, as in Biggers and Baumler, when the accident involves vehicles driving in close proximity on two-lane roads. But we struggle to imagine a scenario in which the law could ever reasonably fault a driver on one side of a broadly divided highway for a collision caused by an oncoming vehicle that loses control, crosses the median, and strikes him before he has time to react.
For these reasons, as a matter of law, Ali‘s negligence was not a substantial factor in bringing about the Blakes’ injuries, the sole proximate cause of which was Salinas‘s loss of control. The defendants also argue that the injury to the Blakes was not foreseeable and that Ali owed no duty to oncoming drivers and passengers under these circumstances. We need not confront these issues, which are rendered superfluous by our holding regarding the substantial-factor element of proximate causation.
III.
We turn now to the effect of our holding regarding Ali‘s liability on the liability of Ali‘s employer, Werner. For the following reasons, the
The jury was asked to assign both (1) “derivative” liability to Werner for inadequate training and supervision of Ali, and (2) “direct” liability to Werner independent of its training and supervision of Ali. The jury did so. The court of appeals affirmed on both counts, but only after reaching the conclusion—which we reverse above—that sufficient evidence supports the jury‘s finding that Ali‘s negligence proximately caused the plaintiffs’ injuries. 672 S.W.3d at 578, 602, 605.
As for Werner‘s “derivative” liability, the court of appeals upheld the jury‘s finding that Werner‘s negligent training and supervision of Ali proximately caused the injuries. Id. at 605. It pointed to evidence that Ali lacked the training and experience to safely drive an 18-wheeler in hazardous conditions and that Werner knew or should have known that he was unfit for the assignment. Id. at 603-05.
Werner‘s negligent training and supervision, even if proved, could not have been a proximate cause of the Blakes’ injuries because Ali‘s negligent driving was not a proximate cause. We have not recognized negligent training or supervision as an independent theory of tort liability. But with respect to the analogous allegation of negligent hiring, we have determined that any such claim “requires negligence by two separate parties: the employer‘s negligence in hiring the employee and the employee‘s subsequent negligent act or omission. Both negligent acts must proximately cause the injury.” Endeavor Energy Res., L.P. v. Cuevas, 593 S.W.3d 307, 311 (Tex. 2019).
The principal theory of “direct” liability, which the court of appeals affirmed, was that Werner created unreasonable risk for other travelers by sending an inexperienced, trainee driver like Ali into winter weather unable to access important updates about the weather. 672 S.W.3d at 591–99. Werner breached this duty, the court of appeals held, by sending Ali on the run without access to important weather updates, allowing him to drive despite his receiving a low score on a recent driving exam, and sending him into the storm untrained to deliver a time-sensitive load. Id. at 599. The Blakes rest their theory of Werner‘s direct liability on this Court‘s recent observation that “a party who takes affirmative acts that create a danger on a public highway can be held responsible for the results of those actions, along with other responsible actors.” See United Rentals N. Am., Inc. v. Evans, 668 S.W.3d 627, 639 (Tex. 2023).
This theory of liability cannot be separated from the predicate question of Ali‘s responsibility for the accident. Like the “derivative” liability theory of negligent hiring and supervision, this “direct” liability
There are no viable theories of liability alleged against Werner that are independent of Ali‘s responsibility for the Blakes’ injuries. All the claims against Werner are, in that sense, “derivative” of Ali‘s liability—for which Werner would bear responsibility as Ali‘s employer, whether or not the Blakes alleged additional theories of Werner‘s liability.7 As a result, all claims against Werner fail for the same reason that all claims against Ali fail: Ali‘s driving did not proximately cause this accident or the resulting injuries, the sole proximate cause of which was Salinas‘s catastrophic loss of control of the vehicle carrying the Blakes.
IV.
The foregoing holdings dispose of all claims and require rendition of judgment for the defendants. We therefore do not reach the parties’ remaining issues. The court of appeals’ judgment is reversed, and judgment is rendered for the defendants.

Notes
a cause that was a substantial factor in bringing about an injury, and without which cause such injury would not have occurred. In order to be a proximate cause, the act or omission complained of must be such that a commercial truck driver using ordinary care would have foreseen that the injury, or some similar injury, might reasonably result therefrom. There may be more than one proximate cause of an injury.
A. To the area of impact, yes, that‘s about right.
Q. Okay.
A. About two seconds.
Q. And that you testified that Mr. Ali had reacted within a half a second?
A. Yeah, he -- Mr. Ali reacted basically as soon as he saw that pickup truck beginning to enter the center median by taking his foot off the gas and moving it towards the brake. So his reaction was appropriate to the conditions that he saw coming up ahead of him.
