WILBUR, Justice.
[¶ 1.] In this negligence case, the circuit court granted the county summary judgment. It found that no duty existed between the county and the plaintiff as a matter of law. The plaintiff appeals asserting a material issue of fact is in dispute whether the county owed the plaintiff a duty. We affirm.
[¶ 2.] On September 30, 2010, Travis Naser died in a one-vehicle accident while he was the passenger in a vehicle being driven by Lowell Langstraat. The accident occurred after Langstraat drove off the road because he failed to negotiate a "T" intersection at a dead-end road. The dead-end intersects two gravel roads in rural South Dakota. The north-south road, 392nd Avenue, is located in Douglas County. The east-west road, 268th Street, is located in Aurora County. After the accident, Travis's wife, Lynn Foster-Naser, brought suit against Aurora and Douglas counties for wrongful death. This appeal concerns only her suit against Aurora County. Foster-Naser alleged that Aurora County negligently failed to maintain the double-arrow sign on 268th Street. She claimed that had the sign been properly maintained it would have warned Langstraat that the dead-end intersection required a sharp right or left turn.
[¶ 3.] Aurora County moved for summary judgment and asserted that it owed no duty to Foster-Naser to maintain the double-arrow sign. It submitted that because 268th Street is a township road, Aurora Township had the duty to maintain the street. Foster-Naser did not dispute that Aurora Township is the governing body responsible for 268th Street. Instead, it responded that an oral agreement existed between the County and the Township whereby the County agreed to maintain the Township's roads. This oral agreement, Foster-Naser averred, created a duty on the part of the County to maintain the double-arrow sign on 268th Street.
[¶ 5.] Foster-Naser disputed that the County merely agreed to plow snow and blade gravel. She directed the circuit court to the County's "Sales History Report" and to Highway Superintendent Konechne's deposition testimony. In the Sales History Report, the County billed the Township for time spent on rock work, back sloping, flood work, shoulder work, disking, spot gravel, blading, snow removal, and replacing a culvert. The Sales History Report also documented that the County sold certain traffic signs to the Township. Konechne testified that he traveled 268th Street as part of the County's duty to maintain the road. Specifically, he remarked that he traveled 268th Street because he "just wanted to make sure we [the County employees] were maintaining it properly." According to Foster-Naser, the Sales History Report and Konechne's testimony created a fact question whether the County assumed responsibility for the Township's statutory duty to maintain the sign on 268th Street.
[¶ 6.] After the hearing, the circuit court issued a memorandum decision and order. It noted that "without question" the Township was responsible for 268th Street and had a statutory duty under SDCL 31-13-1 and -26 to "repair or maintain proper roadway markings or signage." The court further held that SDCL 31-13-1, -26, and -7 gave the Township "explicit and implied authority to contract with other municipalities for road grading, snow removal, and any other maintenance that the township so chooses." Yet, in the court's view, the County would not "be liable under the same negligence theory as the original municipality" unless the County assumed "full control under the contract." See generally Robinson v. Minnehaha Cty., 65 S.D. 628, 277 N.W. 324 (1938). If the County did not assume full control, the court interpreted the law to mean that the County would only be "liable for the duties it specifically contracted to do." See id. at 328.
[¶ 7.] The court then examined whether the County assumed full control when it agreed to maintain the Township's roads. The court noted that the County presented evidence that it only agreed to blade gravel and plow snow for the Township. It rejected Foster-Naser's claim that the County assumed a duty to repair or maintain the Township's signage based on the fact the County sold the Township traffic signs. And it found unpersuasive Foster-Naser's argument that Konechne's use of the word "maintenance" during his deposition meant the County assumed full control over the Township's duty to maintain 268th Street. According to the court, Foster-Naser failed to present specific facts, testimony, contract evidence, or written documentation that "impliedly" or "purportedly" showed that Aurora County exhibited full control over the Township's duty to maintain its roads.
[¶ 8.] The court granted Aurora County summary judgment. Foster-Naser appeals and we restate the issue as follows:
[¶ 9.] For purposes of this appeal, we assume the Township had a statutory duty to maintain the double-arrow sign on 268th Street. So the only question is whether Aurora County assumed the Township's duty when it agreed to maintain the Township's roads. Foster-Naser acknowledges that whether a duty exists is a question of law. Yet she claims that under the circumstances of this case a jury must decide whether the County's oral agreement to provide road maintenance included an agreement to maintain the double-arrow sign on 268th Street. She contends, "[T]he reality is that in the absence of a written agreement, or an actual party to the original oral agreement, no one can prove exactly what the terms of the agreement were, and we must rely on testimony, photographs and sales histories to prove what duties the County had assumed from and was performing for the Township." She then avers that Konechne's deposition testimony and the County's Sales History Report create a material issue of fact in dispute as to the terms of the parties' agreement.
[¶ 10.] Whether a duty exists and the scope of that duty is for the court to determine. Hamilton v. Sommers, 2014 S.D. 76, ¶ 22, 855 N.W.2d 855, 862. The question does not become one for a jury merely because there is an oral agreement between the parties created long ago. Nor does duty become a fact question because Foster-Naser believes a jury could infer from Konechne's deposition testimony and the Sales History Report that the County agreed to do more than blade gravel and plow snow on the Township roads. Duty is a question of law and "[s]ummary judgment is proper in negligence cases if no duty exists[.]" Millea v. Erickson, 2014 S.D. 34, ¶ 9, 849 N.W.2d 272, 275 (quoting First Am. Bank & Tr., N.A. v. Farmers State Bank, 2008 S.D. 83, ¶ 13, 756 N.W.2d 19, 25-26).
[¶ 11.] Here, the circuit court concluded that no duty existed between the County and Foster-Naser because the evidence did not establish that Aurora County assumed full control over the Township's statutory duty to maintain 268th Street. "On review, we apply the same test as the trial court: we probe the record for material facts, resolve disputed facts in favor of the nonmoving party, and decide whether the moving party is entitled to a judgment as a matter of law." Fisher v. Kahler, 2002 S.D. 30, ¶ 5, 641 N.W.2d 122, 125. "We require `those resisting summary judgment to show that they will be able to place sufficient evidence in the record at trial to support findings on all the elements on which they have the burden of proof.'" Bordeaux v. Shannon Cty. Schs., 2005 S.D. 117, ¶ 14, 707 N.W.2d 123, 127 (quoting Chem-Age Indus., Inc. v. Glover, 2002 S.D. 122, ¶ 18, 652 N.W.2d 756, 765). General allegations without specific supporting facts are insufficient. Id. And "proof of a mere possibility is never sufficient to establish a fact." Estate of Elliott v. A & B Welding Supply Co., Inc., 1999 S.D. 57, ¶ 16, 594 N.W.2d 707, 710.
[¶ 12.] From our review of the record in a light most favorable to Foster-Naser, there is no evidence that the County orally agreed to assume full control over the Township's road maintenance duties. More specifically, there is no evidence that the County agreed to maintain, repair, or install the Township's signage or the double-arrow
[¶ 13.] The circuit court also did not err when it rejected Foster-Naser's claim that the County's oral agreement to provide "road maintenance" includes, as a matter of law, "the maintenance of existing signs and other items appurtenant to roadways." Foster-Naser relies on Kiel v. DeSmet Township, where we held that the duty under SDCL 31-32-10 to repair a county highway includes a "duty to maintain and keep" an erected warning "sign in reasonable repair for the safety of public travel." See 90 S.D. 492, 497, 242 N.W.2d 153, 155 (1976). Kiel, however, implicated our statutory interpretation of a governing body's duty to maintain a road. This case concerns the County's contractual agreement to maintain the Township's roads, and Foster-Naser has not presented sufficient probative evidence that the County's contractual agreement to provide road maintenance included an agreement to maintain the Township's signage.
[¶ 14.] Affirmed.
