ROWLAND
v.
MURPHY OIL USA, INC.
No. A06A0893.
Court of Appeals of Georgia.
July 13, 2006.
*478 Smith & Phelps, Joseph L. Phelps III, Jesup, for appellant.
Drew, Eckl & Farnham, Peter H. Schmidt II, Christopher J. O'Donnell, Brunswick, for appellee.
PHIPPS, Judge.
Gladys Rowland broke her wrist when she tripped and fell over an advertising sign at Murphy Oil USA, Inc.'s gas station in Jesup. She sued Murphy Oil for negligently placing the sign in the path of customers and failing to warn her of the hazard. The trial court granted Murphy Oil's motion for summary judgment, ruling that the sign was an open and obvious static condition and that Murphy Oil lacked superior knowledge of any hazard associated with it. Rowland appeals, but we find no error and affirm.
To win summary judgment, the moving party must show that there is no genuine issue of material fact and that the undisputed facts, viewed in a light most favorable to the nonmoving party, warrant judgment as a matter of law.[1] We review a trial court's grant of summary judgment de novo.[2]
Viewed in the light most favorable to Rowland, the record shows that she drove to Murphy Oil's gas station one November morning, pumped gas into her car, then walked to the cashier's window to pay. After paying, she walked back toward her car. Along the way, she tripped over the metal support legs of a large advertising sign that stood at the end of a gas pump island. As a result of the fall, Rowland broke her wrist.
She testified that she had been to that gas station multiple times before her fall. She also testified that she had parked at the same pump island before, although on the other side, and had walked to the cashier's window before. On the day of her fall, she walked past the sign on her way to the cashier's window without incident, but she did not remember seeing it. She did not recall seeing any debris or other distractions along her route.
Barry Colbert, the gas station manager, testified that he was at work when Rowland fell. He testified that the station had four of the signs, placed at the ends of the four pump islands. The sign legs were long and black and, according to Colbert, "st[u]ck out like sore thumbs" against the gray pavement. He saw Rowland pass one of the signs without incident on her way up to the cashier's window, and she returned to her car by the same route. When asked whether he knew *479 of anyone else falling over the signs, Colbert responded:
Never had any problems with them out there. And, you know, the signs have been there for just about since the station opened. It's a Windmaster sign with long legs on it that advertises cigarettes, cigarette carton prices and pack prices, and it's just something that's always been there. After a while you just kind of disregard it. You know, it's just something that's always there.
Business owners are liable to their customers for injuries caused by the owners' failure to exercise ordinary care to keep their premises and approaches safe.[3] They are not, however, insurers of their customers' safety. Rather,
the basis of liability of an owner to an invitee who is injured is the superior knowledge of the owner of the existence of a condition that could subject the invitee to an unreasonable risk of injury. It is when the perilous instrumentality is known to the owner or occupant and not known to the person injured that a recovery is permitted.[4]
Our case law has distinguished between "emergency conditions existent on an owner's premises and static conditions which are not inherently dangerous in and of themselves."[5] With respect to static conditions, "where there is nothing to obstruct or interfere with the invitee's ability to see the static defect, the owner is justified in assuming that the visitor will see it and realize the risks involved."[6] Thus, "when a person has successfully negotiated an alleged dangerous condition on a previous occasion, that person is presumed to have knowledge of it and cannot recover for a subsequent injury resulting therefrom."[7]
Applying the static condition rule, the trial court concluded that Rowland could not prevail against Murphy Oil as a matter of law. Rowland, however, argues that the sign was not a static condition, but a moveable object whose position could have varied from day to day. Our case law has defined a static condition as "one that does not change"[8] and is not inherently dangerous.[9] The signs posed no inherent danger, and Colbert testified that they had "always been there" since the station opened. Thus, although the signs theoretically could have been moved, there is no evidence that they ever were moved, or that they were a transient or temporary condition.[10] Accordingly, we agree with the trial court that they were a static condition.
Rowland also argues that she did not notice the signs before she fell. It is undisputed, however, that she had been to the gas station before and had successfully navigated past the sign in question just moments before tripping over it. Moreover, there was no evidence that Murphy Oil obscured or concealed the sign; to the contrary, it was an advertisement meant to attract customers' attention. And although Rowland asserts in her brief that it is "common knowledge" that black objects such as the sign's support legs "visually `blend in' to concrete pavement and are difficult to see thereon," the only evidence in the record concerning the visibility of the legs was Colbert's testimony that they "stuck out like sore thumbs." Finally, there was no evidence that anyone else had ever tripped over the signs. Under these circumstances, *480 the trial court properly awarded summary judgment to Murphy Oil.[11]
Judgment affirmed.
