OPINION
Appellant, who was injured in a traffic accident, challenges the trial court’s decision granting respondent county discretionary immunity in her negligent maintenance claim involving an allegedly dangerous intersection. We affirm.
FACTS
In May 1994, Phu Chau Nguyen was driving westbound on County State Aid Highway 42, a two-lane, undivided highway, with his sister, appellant Ai Viet Nguyen. As the brother slowed to make a left turn onto County Road 83, he had difficulty observing whether the stoplight was green or red due to darkness and poor weather. As he made the left turn, a vehicle traveling eastbound on Highway 42 struck the passenger side of his car, injuring appellant. At the time, the intersection had neither a turn lane nor a turn signal for traffic turning left onto County Road 83.
Appellant sued respondent Scott County, alleging, among other claims, negligent maintenance and negligent failure to warn of the dangerous intersection. Determining that the county had discretionary immunity, the trial court granted partial summary judgment for the county on the negligent maintenance claim. On its own motion, the court subsequently granted summary judgment for the county on the failure to warn claim because appellant had failed to show a genuine fact issue on his claim that the lack of better signs was a proximate cause of the accident.
ISSUE
Did the trial court err, as a matter of law, in concluding that respondent had discretionary immunity from appellant’s negligent maintenance claim?
ANALYSIS
The determination of whether a governmental action is a discretionary function is a legal question subject to de novo review.
Snyder v. City of Minneapolis,
By statute, a county generally is liable for its torts, but the county can assert immunity as an exception to the rule, even after abuse in its exercise of discretion, against “[a]ny claim based upon the performance or the failure to exercise or perform a
*723
discretionary function or duty.” Minn.Stat. §§ 466.02, .03, subd. 6 (1996). For immunity purposes, discretionary acts are planning-level actions that require evaluating such factors as the financial, political, economic, and social effects of a given plan.
Holmquist,
Discretionary immunity applies in this case because the challenged conduct, the county’s decision to delay the intersection improvements, occurred at the planning level. According to the undisputed testimony of the county’s highway engineer, the county board initially considered upgrades to the intersection in 1991, approved the improvements in 1992, but did not schedule funding for the project until 1997 due to budgetary limitations. Because the county board reached its decision to postpone construction of improvements by balancing fiscal considerations, the trial court did not err by applying discretionary immunity.
Steinke v. City of Andover,
Although appellant concedes that the county’s decision normally would trigger discretionary immunity, she argues that the county should not receive immunity because many collisions had occurred at the intersection, and the county had an independent duty to correct this dangerous condition. Appellant relies on a series of decisions of this court suggesting that discretionary immunity does not apply to decisions that involve warning the public of known hazards.
Ostendorf v. Kenyon,
Appellant’s argument fails for several reasons. First, the supreme court has corrected this line of cases by making it clear that whether the government warned “the public of known hazards is not relevant in determining whether the conduct involved discretionary decision making.”
Steinke,
In addition, the cases cited by appellant are distinguishable as a matter of fact because they involved known dangers that the government could correct through such relatively inexpensive remedies as guardrails or warning signs, which may not require a policy decision regarding the allocation of resources. Unlike the government entities in those cases, respondent county could not immediately remedy this dangerous condition because its budget lacked the financial resources to cover the expenses of redesigning the intersection until 1997, three years after appellant’s accident. 1
Appellant also challenges the dismissal of her failure to warn claim, asserting that a jury could have found that the lack of warning signs was a substantial factor in the accident. Although proximate cause generally is a question of fact for the jury, it is a question of law “where reasonable minds can arrive at only one conclusion.”
Lubbers v. Anderson,
Appellant submitted no evidence indicating how the lack of a warning sign was a substantial factor in creating the accident. “Mere speculation, without some concrete evidence, is not enough to avoid summary judgment.”
Bob Useldinger & Sons, Inc. v. Hangsleben,
DECISION
The trial court correctly found that the county had immunity because the county’s *725 decision to delay the installation of road improvements involved the balancing of policy considerations, regardless of any known dangers at the intersection. There was also no error in dismissing appellant’s alternative claim that the county breached a duty to give warnings.
Affirmed.
Notes
. There is no evidence in the record to suggest that respondent could install a turn lane or a turn signal as an ordinary part of its current budget.
