This is an appeal from the judgment of the trial court after a jury returned a verdict in favor of the District of Columbia on appellant’s claim for damages resulting from a collision with a District of Columbia ambulance. Appellant contends that the trial court committed reversible error by concluding, as a matter of law, that the ambulance was on an emergency run and thus submitting to the jury only the issue whether or not the District of Columbia in its operation of the ambulance was grossly negligent.
D.C.Code § 1-1212, the District of Columbia’s waiver of immunity statute, provides the following exception: “in the case of a claim arising out of the operation of an emergency vehicle on an emergency run the District shall be liable only for gross negligence.”1 D.C.Code § 1-1211(5)(A) defines “emergency vehicle” to include a vehicle assigned to the Fire Department that is not designated as a non-emergency vehicle. D.C.Code § 1-1211(4) defines “emergency run” as “the movement of a District-owned vehicle, by direction of the operator or of some other authorized person or agency, under circumstances which lead the operator or such persons or agency to believe that such vehicle should proceed expeditiously upon a particular mission or to a designated location for the purpose of dealing with a supposed fire or other emergency, an alleged violation of a statute or regulation, or other incident requiring emergency action, or the prompt transportation to a place of treatment or greater safety of an alleged sick or injured person.”
The evidence at trial showed that appellant was starting to make a left turn from Naylor Road onto 30th Street in Southeast Washington, D.C., when her car was hit by an ambulance which was attempting to pass her on her left side and which had crossed the double median line of the street to do so. The testimony of the *929paramedics2 was that they were transporting a woman who had called 911 after falling and suffering a head wound. Although the paramedics had given the woman’s injuries a low rating of seriousness, they transported her as an emergency run (with siren and flashing lights) because it was Fire Department policy and procedure to so treat all transports of injured persons resulting from 911 calls.3 At the conclusion of the testimony, the court instructed the jury that, as a matter of law, the ambulance in this case was on an emergency run, and that they were to decide whether the District of Columbia was grossly negligent in its operation of the ambulance.
Appellant contends that § 1-1211(4), in its use of the words “under circumstances which lead the operator or such persons or agency to believe that such vehicle should proceed expeditiously,” requires the evaluation of the circumstances to be made on an individual, case-by-case basis. She further contends that the Fire Department’s internal policy, which treats all patient transports resulting from 911 calls as an emergency run, conflicts with this requirement. Instead, she argues, the determination whether the ambulance was on an emergency run should be made by the jury.4
The District of Columbia Fire Department’s policy decision, which dictates the circumstances in which its ambulance operators must respond with an emergency run, speaks to the statutory provision that the agency may determine when an ambulance is on an emergency run. See D.C.Code § 1-1211(4). The trial court correctly concluded that the determination whether the Department’s policy satisfies this statutory provision, or whether an individualized determination must be made, is a question of law, and thus is not appropriate for jury determination. See, e.g., Doe by Fein v. District of Columbia, 697 A.2d 23, 27-29 (D.C.1997) (determination whether police report satisfies statutory notice requirement of D.C.Code § 12-309 is question of law for court).5 We do not see a conflict between the Fire Department’s policy and § 1-1211(4) since the statute, which expressly provides for the decision to be made by “the operator or ... persons or agency,” does not rule out the adoption of a policy such as the one at issue here. Furthermore, the policy does not appear unreasonable on its face.
Accordingly, we conclude that the trial court did not err in refusing to submit to the jury the question of whether the ambulance in this case was on an emergency run.
Affirmed.
. The relevant portion of § 1-1212 reads in full: “Hereafter the District of Columbia shall not assert the defense of governmental immunity in any suit at law in which a claim is asserted against it for money only on account of damage to or loss of property or on account of personal injury or death caused by the negligent or wrongful act or omission of any employee of the District occurring as the result of the operation by such employee, within the scope of his office or employment, of a vehicle owned or controlled by the District: Provided, that in the case of a claim arising out of the operation of an emergency vehicle on an emergency run the District shall be liable only for gross negligence.’’ (Emphasis added.)
. Depositions of two paramedics were read to the jury, but the deposition testimony was not transcribed, nor were the depositions made part of the record. The summary provided here is based on the representations in the parties’ briefs.
. The clearest identification of the source of this policy is provided in appellant’s pretrial Trial Brief, in which she quoted the Fire Department’s designated corporate representative as stating, in a deposition, that the policy is "a standing order in our Operations Procedures Manual.” This standing order is not provided in the record or the briefs, but the parties appear to agree on its content.
. Appellant does not appear to contend that the ambulance in this case was not an "emergency vehicle.”
. Additionally, we have noted that generally, "waivers of immunity are to be read narrowly.” Abney v. District of Columbia, 580 A.2d 1036, 1041 (D.C.1990). Consistent with this principle, we have refused to give an unpublished Metropolitan Police Department General Order the effect of expanding the District’s liability under § 1-1212. See id.
