delivered the opinion of the Court.
To prevail in a premises-liability case, an invitee must prove that the premises owner had actual or constructive knowledge of a dangerous condition on the premises. In this slip-and-fall case, we must decide whether evidence that the premises owner’s employee was in close proximity to the dangerous condition right before the plaintiff fell, without more, is legally sufficient to charge the premises owner with constructive notice. We hold that it is not, absent some evidence demonstrating that the condition existed long enough that the premises owner had a reasonable opportunity to discover it. Because the plaintiff here presented no such evidence, we reverse the court of appeals’ judgment and render judgment that the plaintiff take nothing.

During a routine shopping trip to a local Wal-Mart store, Lizzie Reece bought a chili dog from the snack bar. After purchasing her food but before leaving the snack bar, Reece slipped and fell in a puddle of clear liquid. The puddle was about the size of a small- or medium-sized pizza and was to the side of the usual line snack-bar customers followed. Reece injured her right knee and underwent surgery to repair a ligament tear.
*814 Shortly before Reece’s fall, Stephen Cloyd, a Wal-Mart employee who was on break, walked past the area where Reece fell and bought a beverage from the snack bar directly in front of her, but he did not then notice the spill. Cloyd had walked away from the counter and was about five to eight feet from Reece when she slipped and fell. He testified that only then did he notice the liquid on the floor. The store manager acknowledged that the self-service drink and ice machines increased the risk of spills in the snack-bar area. And store policy required employees to intervene whenever they passed a known hazard anywhere in the store. But there was no evidence, direct or circumstantial, about how the liquid came to be on the floor or how long it had been there before Reece fell.
Reece sued Wal-Mart for her injuries, and the trial court rendered judgment on the jury’s verdict in her favor. The court of appeals affirmed, holding that evidence of Cloyd’s proximity to the spill, together with Wal-Mart’s awareness of the propensity for spills in the area and store policy that required employees to intervene if they discovered dangerous conditions on the premises, was sufficient to establish constructive notice.

Wal-Mart owed Reece, its invitee, a duty to exercise reasonable care to protect her from dangerous conditions in the store that were known or reasonably discoverable, but it was not an insurer of her safety.
See Wal-Mart Stores, Inc. v. Gonzalez,
Reece argues that she satisfied her burden by showing that Wal-Mart’s employee walked past the spill right before she fell. According to Reece, requiring proof of how long the spill had been on the floor improperly elevates the temporal element of premises liability over the more relevant inquiry — whether the premises owner had a reasonable opportunity to discover the danger. Reece claims that Cloyd’s proximity to the spill is some evidence that Wal-Mart had a reasonable opportunity to discover it.
Wal-Mart, on the other hand, contends that Reece’s position is inconsistent with fundamental premises-liability concepts. According to Wal-Mart, an employee’s proximity to a hazard cannot, by itself, impute constructive notice because such a rule would not afford premises owners a fair opportunity to inspect and correct, or warn about, the condition. Wal-Mart claims that mere proof an employee might have discovered the condition by being close to it misstates the plaintiffs burden and requires premises owners to be omnis *815 cient. Such a rule, Wal-Mart argues, imposes constructive notice the instant a hazard is created, whether or not there was a reasonable opportunity to discover it, thus violating the principle that premises owners are not insurers of them invitees’ safety.
The parties’ positions mirror a split among our courts of appeals regarding the import of proximity evidence. Some courts have held that proximity evidence alone is insufficient to establish constructive notice absent some indication that the hazard existed long enough to give the premises owner a reasonable opportunity to discover it.
See Wal-Mart Stores, Inc. v. Rosa,
Other courts, including the court of appeals in this case, have suggested that evidence of an employee’s proximity to a dangerous condition can establish constructive notice, although many of those decisions cite other evidence indicating a temporal element.
See Wal-Mart Stores, Inc. v. Garcia,
The rule requiring proof that a dangerous condition existed for some length of time before a premises owner may be charged with constructive notice is firmly rooted in our jurisprudence.
See Lone Star Gas Co. v. Ballard,
The so-called “time-notice rule” is based on the premise that temporal evidence best indicates whether the owner had a reasonable opportunity to discover and remedy a dangerous condition. See id. at 102-03. An employee’s proximity to a hazard, with no evidence indicating how long the hazard was there, merely indicates that it was possible for the premises owner to discover the condition, not that the premises owner reasonably should have discovered it. Constructive notice demands a more extensive inquiry. Without some temporal evidence, there is no basis upon which the factfinder can reasonably assess the opportunity the premises owner had to discover the dangerous condition.
What constitutes a reasonable time for a premises owner to discover a dangerous condition will, of course, vary depending upon the facts and circumstances presented. And proximity evidence will often be relevant to the analysis. Thus, if the dangerous condition is conspicuous as, for example, a large puddle of dark liquid on a light floor would likely be, then an employee’s proximity to the condition might shorten the time in which a jury could find that the premises owner should reasonably have discovered it. Similarly, if an employee was in close proximity to a less conspicuous hazard for a continuous and significant period of time, that too could affect the jury’s consideration of whether the premises owner should have become aware of the dangerous condition. But in either case, there must be some proof of how long the hazard was there before liability can be imposed on the premises owner for failing to discover and rectify, or warn of, the dangerous condition. Otherwise, owners would face strict liability for any dangerous condition on their premises, an approach we have clearly rejected.

We now turn to the evidence in this case. Reece concedes that she presented no evidence to indicate how long the spill existed before she fell. There was no evidence that the spill was conspicuous—it was not large and consisted of a clear liquid on a light tile floor. There was no evidence that Cloyd saw the spill before Reece fell or that it was there when he
*817
approached the counter. There was no evidence indicating when or how the spill came to be on the floor. Nor was there evidence concerning the condition of the spilled liquid that might indicate how long it had been there. Considering the evidence in the light most favorable to Reece, we hold that there is no evidence to support the conclusion that Wal-Mart had constructive notice of the dangerous condition.
See Bradford v. Vento,
The court of appeals relied on two factors in addition to proximity that it believed constituted some evidence of constructive notice. First, the court noted Wal-Mart’s acknowledgment that the self-serve drink machine increased the likelihood of spills in the snack-bar.
Finally, Reece asserts that
Gonzalez
does not apply here because an employee’s proximity to a dangerous condition constitutes direct, rather than circumstantial, evidence of constructive notice.
See Gonzalez,
IV
It was Reece’s burden to establish that it was more likely than not that Wal-Mart should have been aware of the spill because it existed long enough to give Wal-Mart a reasonable opportunity to discover and rectify it, or to warn about it. Because Reece failed to meet that burden, we reverse the court of appeals’ judgment and render judgment that she take nothing.
