OPINION
¶ 1 In this appeal, we are asked to decide whether the trial court erred in allowing a jury to determine that the state negligently had failed to prevent elk from entering portions of Interstate 40 (1-40) just east of Flagstaff. Based on the particular facts presented in this case, we conclude that the issue was properly presented to the jury and affirm the judgment entered below.
¶2 In December 1998, Jerry Booth was severely injured when the car he was driving collided with an elk lying in the roadway on 1-40 near milepost 211. He sued the state on his own behalf and that of his daughters, alleging that 1 — 40 was not reasonably safe due to the presence of elk on the highway. At trial, he contended that the state negligently had failed to evaluate the known hazard of elk crossing the highway, use appropriate fencing, clear cut vegetation, or reduce the speed limit. The state moved for summary judgment, arguing that it could not be held hable for an injury caused by a wild animal not in the state’s possession or control. The trial court denied the motion, and the jury returned a substantial verdict in favor of the Booths. On appeal, the state argues that it was entitled to judgment in its favor as a matter of law. 1
¶ 3 Viewed in the light most favorable to upholding the verdict,
Medley v. Arndt,
¶ 4 The fencing along 1-40 is not designed to, and does not, keep elk off the highway. As the elk population increased, so too did the number of collisions between elk and automobiles. In the late 1980s, automobile collisions involving elk increased at rates of up to one hundred percent per year. On the section of 1-40 within about five miles on either side of the accident site, there were 168 reported collisions between automobiles and elk or deer between 1994 and 2000 — an average of over two collisions per mile per year. In response to the increased accident rate, the state posted additional warning signs but took no other measures aimed at preventing collisions with elk.
¶5 The Booths introduced evidence that the Federal Highway Administration has adopted standards providing that “[f]encing along a highway is a means of preventing unwanted and likely intrusion of animals ... from outside the right-of-way line ... into the vicinity of moving traffic or onto the operating right-of-way,” and that seven- to ten-foot high fences “may be needed along the highway at the few elk and buffalo ranges in the western States.” 2 An expert for the Booths testified that nine other states and Canada use eight-foot fences and underpasses to prevent elk and deer from accessing interstate highways. He also testified that wildlife warning signs are not effective in reducing collisions between animals and automobiles. Reports collected by an employee of the Arizona Game and Fish Department indicated that the construction of higher fences and wildlife underpasses could reduce such collisions by as much as ninety-six percent.
¶ 6 The Booths also introduced evidence that these and other additional steps to prevent collisions between vehicles and elk have been implemented on a different Arizona highway. The evidence included a report by the Arizona Department of Transportation, a portion of which provides that “[i]n 1994, Arizona State Route 260 [SR-260] was identified as a route requiring immediate action to reduce rapidly increasing accidents” involving deer and elk. According to the report, such collisions had occurred in one twenty-mile section of that highway at a rate of 1.22 collisions per mile per year between 1992 and 1997. The report characterized that accident rate as “excessive.” The Booths also established that in conjunction with the widening of SR-260, the state had implemented a mediation plan called “Project Elk Alert.” The project included public education to warn of the hazard on that particular roadway, vegetation management to improve visibility and reduce the amount of palatable vegetation on the road shoulders, and wildlife fences and underpasses designed to keep elk off the highway while allowing them to cross from side to side.
¶7 Citing the court’s ability to “set the outer limits” of what may be considered a negligent act, the state argued in its briefs that we should adopt the “doctrine of
ferae naturae
” and hold as a matter of law that the state cannot be held liable for injuries caused by indigenous wild animals.
3
Ferae naturae
means “of a wild nature or disposition.”
See Black’s Law Dictionary
635 (7th ed.1999). The doctrine of animals
ferae naturae
relates primarily to property rights.
See Nicholson v. Smith,
¶ 8 From this doctrine has emerged the general principle that a landowner cannot be held
strictly
hable for the acts of animals
ferae naturae
on his land.
See, e.g., id.
This case, however, sounds in negligence, not strict liability, and even cases relied upon by the state recognize that the doctrine does not completely bar liability for claims based on the negligence of the defendant. “[M]ost courts [that] have considered the issue recognize the possibility that a claim for negligence may not be precluded by
ferae naturae
per se[;] ... [those] courts generally agree they
may
impose a duty on a premises owner” for negligent acts causing injury from wild animals.
Id.
at 61. In practice, few courts have actually imposed such a duty.
Id.
Given the fact that wild animals are not readily controllable and are often unpredictable, that result is not surprising. In most of the cases cited by the state, the defendants were found not liable precisely because they could not reasonably have foreseen an injury or protected against it.
See, e.g., Brunelle v. Signore,
¶ 9 The state cites no case in which a court has categorically barred negligence claims based on injuries caused by wild animals. Rather, in negligence cases, courts have used the term ferae naturae as shorthand for the general proposition underlying the doctrine — that wild animals exist throughout nature, they are generally not predictable or controllable, and therefore, without more, they are neither the property nor the responsibility of the owner or occupier of land on which they are found. Thus, the doctrine has not been historically applied so as to alter the traditional analysis of a negligence claim.
¶ 10 “The basic elements of actionable negligence are a duty owed to the plaintiff, a breach thereof and an injury proximately caused by the breach.”
Ballesteros v. State,
¶ 11 Because the standard of care required to fulfill a duty is a question of reasonableness, a court may grant judgment as a matter of law only if no reasonable jury
¶ 12 In support of a different result, the state relies principally on two out-of-state cases it insists provide authority for precluding governmental liability for claims based on highway collisions with wild animals:
Rippy
and
Mann v. State,
Short of fencing every inch on Commonwealth-owned highway in non-urban areas or permitting a wholesale obliteration of this Commonwealth’s deer population, we can conceive no method of correcting the problem of wild animals wandering onto the highways. As neither of these methods is feasible, the problem of wild animals on the highways is simply not “conceivably correctable”____
¶ 13 Although
Mann
is more applicable here than
Rippy,
it is not contrary to our decision. In
Mann,
the court dismissed the plaintiffs negligence action in which the plaintiff had alleged only that a deer had attempted to cross a highway and caused a collision with his vehicle.
¶ 14 Finally, although the court in
Mann
suggested in dicta that any action for injuries caused by deer on the highways would place an unreasonable burden on the state, the court’s holding was based on a New York common law doctrine of sovereign immunity for injuries resulting from governmental actions taken in the public trust.
¶ 15 The County Supervisors Association, which has appeared as
amicus curiae,
urges us to adopt the state’s position as a matter of public policy. It analogizes the state’s highways to water canals in that they are both “indispensable for maintaining life and prosperity,”
see Salt River Valley Water Users Ass’n v. Superior Court,
¶ 16 The
Salladay
doctrine and the fireman’s rule are based primarily on policy considerations, but those policy concerns do not apply here. Although canals and highways may be of equal importance to our state, they are used very differently. The public does not use canals for transportation. Therefore, the risks associated with the canal system and the highway system are simply not comparable. The rationale for the fireman’s rule is that emergency workers who hold jobs that present inherent risks are compensated for performing those duties and therefore should not be entitled to bring a private cause of action when they suffer harm from those risks.
See Grable,
¶ 17 Rather, the state and the Association ask us to preclude liability based on public policy considerations arising from the unpredictability of wild animals. The evidence presented at trial, however, was that elk predictably cross I-A0 near milepost 211. When the policy behind a doctrine is not applicable, the doctrine itself may not be either. Our supreme court refused to apply the
Salladay
doctrine in a case in which the plaintiff had been injured by a cable gate crossing a canal road because the policy considerations behind the doctrine did not apply to the type of accident at issue.
Bledsoe v. Goodfarb,
¶ 18 The state also argues that it should be relieved from liability on public policy grounds because of “the tremendous cost and futility of trying to animal-proof our highways.” But neither the state’s nor the Association’s briefs direct us to any facts in the record which establish that such costs are either tremendous or unreasonable. Furthermore, the state does not dispute that it has undertaken substantial measures to prevent collisions with large animals on SR-260 and that such measures can be ninety-six percent effective. Such actions suggest that the state itself has concluded that protecting our citizens from collisions with large animals is neither prohibitively expensive nor futile.
¶ 19 The Association warns that, by failing to categorically bar claims based on injuries caused by wild animals on Arizona’s highways, we expose governmental entities to
¶ 20 Our decision here does not divest trial courts of their gate-keeping function. Not every ease involving a collision with a wild animal will necessarily merit presentation to a jury.
See Coburn,
¶ 21 Our conclusion here does not mean governmental agencies must “animal proof’ all highways. Nor does it suggest any particular action must be taken. Rather, we merely conclude that, based on the record in this case, including the uncontested fact that there were recorded 168 elk- or deer-related collisions on this eleven-mile stretch of highway within seven years, the reasonableness of the state’s inaction in addressing and seeking to remedy the risk to drivers was a question for the jury.
See Dunham,
¶ 22 Although the Association acknowledges that the state has taken measures to reduce collisions with large animals in some high risk areas, it asserts that “[w]here, when and whether [such measures] should be undertaken is a matter properly left to the legislature, which is uniquely equipped to weigh the cost and efficacy of such measures.” However, the Association has not directed us to a particular statute or provided us with any other support for the proposition that the legislature intended to insulate the state from liability for this type of incident.
Cf.
A.R.S. §§ 12-820.01, 12-820.02 (extending absolute or qualified immunity to public entities in certain specified
¶ 23 In the absence of any persuasive public policy reason for immunizing the state from liability for all injuries caused by wild animals, no matter how foreseeable the risk or how feasible the remedy might be, and in the absence of any expression of legislative intent to limit state liability in this arena, we decline to expand the common law as the state and the Association suggest.
¶ 24 Affirmed.
Notes
. The state also moved for a judgment as a matter of law following the close of the plaintiffs’ case-in-chief. After the verdict, the state filed a motion for new trial, claiming the trial court incorrectly had denied the state's motion for judgment as a matter of law and, among other things, that it improperly had instructed the jury. In its notice of appeal, the state specified that it was challenging the trial court's denial of the motion for new trial, but, other than a concluso-ry statement in its opening brief that the court's "erroneous instruction ... prodded the jury to find for these Plaintiffs,” it has not raised any other issues on appeal. Therefore, we need only decide whether the jury should have been allowed to determine if the state had been negligent.
. Although Arizona has not adopted these standards by statute, they are used as "guideflines] in designing and developing” roadway plans.
. At oral argument, the state clarified that it was not quite seeking a complete bar to negligence claims involving wild animals. It conceded that the state could still be held liable if it either: (1) takes an action to increase the risk of harm by a wild animal, or (2) is aware that a specific animal is posing a risk at a certain time and specific location and fails to take action to protect the public. These potential exceptions were only obliquely referred to in the state's opening brief, which primarily sought to "preclude^ liability for injuries inflicted by wild animals in their natural habitat.” We therefore focus our opinion on the issues squarely raised by the briefs.
