Thе case before us arises under our diversity jurisdiction. Jaimee Lee Mena, the plaintiff below, filed a complaint against defendants General Insurance Company of America and SAFECO Insurance Company (“Safeco”), arguing that her Safeco automobile insurance policy entitles her to aggregate or “stack” the underin-sured motorists coverage under the policy. Mena was insured under a single policy covering three vehicles, and sought a declaratory judgment that would allow her to *1161 stack her underinsured motorists coverage for each vehicle to compensate for bodily injuries suffered in an automobile accident. After tendering the underinsured motorists limit for a single vehicle, Safеco denied additional coverage. On cross motions for summary judgment the district court denied Mena’s claim of additional coverage and granted summary judgment to the defendants. Having reviewed the policy in accordance with Wyoming law, we agree with the district court and AFFIRM the grant of summary judgment to Safeco.
I
Mena suffered serious injuries in an automobile accident while riding as a passenger in a vehicle operated by her son. She insured the vehicle in which she was riding, along with two other vehicles, under a single policy issued by Safeco. The policy provided coverage for bodily injury, medical payments, automobile damage, and losses involving uninsured and underin-sured motorists. Under the policy’s terms, Mena wаs eligible to recover (and has recovered) $25,000 in bodily injury liability. The policy also provides underin-sured motorists coverage of $100,000 per person for each of the three covered vehicles. Safeco has tendered $100,000 to Mena as payment pursuant to the underin-sured motorists provision, bringing its total payment to $125,000 for the collision.
Mena sued Safeco in state court seeking a declaration that she is entitled to receive up to $800,000 in underinsured motorists coverage, representing $100,000 for each of the three vehicles covered by the policy. She also sought damages and attorney’s fees. Following removal to federal court, both sides filed cross motions for summary judgment. The princiрal issue before the court was whether Mena was entitled to stack the underinsured motorists coverage on each of the three vehicles. After reviewing the policy, the court concluded that the policy unambiguously prohibits stacking underinsured motorists coverage, granted Safeco’s motion for partial summary judgment, and dismissed the case with prеjudice. Mena appeals.
II
We apply Wyoming law to the question of whether Mena is entitled to stack the underinsured motorists coverage on the three vehicles covered by the policy.
Cooperman v. David,
A
The Wyoming Supreme Court has longstanding jurisprudence answering whether insureds are entitled to stack uninsured motorists coverage based on public policy gleaned from Wyoming’s Uninsured Motor Vehicle Coverage Act, which requires carriers to make available uninsured motorists coverage to their insureds. However, the court has only recently confronted the issue of whether insureds are entitled to stack underinsured motorists coverage, an issue not addressed by Wyoming statute. The supreme court’s first foray into the field of uninsured motorists coverage stacking came in
Ramsour v. Grange Ins.
Assoc.,
In
Commercial Union Ins. Co. v. Stamper,
Wyoming’s uninsured motorists jurisprudence guided the state supreme court when it confronted, for the first time, a case involving stacking of underinsured motorists provisions in
Aaron v. State Farm Mut. Auto. Ins. Co.,
Based on these principles, the court established the rule that courts should deny “aggregation of uninsured or under-insured motorist coverage from separate policies for which separate premiums have been paid” only if the policies contain anti-stacking provisions detailed “clearly аnd unambiguously in terms that a lay-insured of ordinary intelligence could easily comprehend.” Id. The court announced a presumption that “the payment of additional separate premiums ... was intended to purchase additional ‘stackable’ coverage commensurate with the insured’s damages.” Id. at 933. Therefore, Aaron created a rule that where a plaintiff has paid separate premiums for separate policies containing underinsured motorists limits, underinsured motorists coverage will be stacked unless the policies contain clear and unambiguous anti-stacking provisions.
Contrary to the conclusion of the court below, the Aaron rule is inapplicable to this case. By its terms, the rule applies to inter-policy stacking cases, and the Wyoming Supreme Court has determined that rules applying to inter-policy stacking do not necessarily extend to intra-policy stacking. See id. at 933 n. 5 (“in our decision in Commercial Union the court was careful to emphasize that the insured was attempting to stack multiple forms of coverage within a single insurance policy.”). Additionally, the rule applies only in cases involving “separate policies for which separate premiums have been paid.” Id. at 932 (emphasis added).
In this case, the rеcord reveals that Mena pays a single premium for a single Safeco policy. The declaration sheet shows a charge for a “total premium for all vehicles” of $975.30. Under Wyoming law, it does not alter the analysis that the declaration sheet breaks down the total premium by vehicle, and then within each vehicle by form of coverage.
See Commercial Union,
Rather than presuming that the Safeco policy permits stacking absent clear and unambiguous anti-stacking language as would be required by
Aaron,
“we will defer to the language of the insurance policy itself’ to detеrmine if it permits intra-policy stacking.
Id.
at 538. When interpreting the policy, we must adhere to the following tenets of insurance agreement construction established by the Wyoming Supreme Court: (1) words must be given their common and ordinary meaning, and courts may not torture policy language to create an ambiguity; (2) the parties’ intention, ascertained from the pоlicy language when viewed in the light of what the parties must reasonably have intended, receives primary consideration; (3) the policy must not be construed so strictly as to contradict the policy’s general object; (4) courts may not rewrite lawful policy terms; (5) absent ambiguity, courts must enforce the policy according to its terms and not engage in construction; (6) if the policy is ambiguous, courts must construe the contract liberally in favor of the insured and strictly against the insurer.
See Aaron,

*1164
P.3d at 933. Applying these canons of construction, and reviewing the grant of summary judgment de novo, viewing the evidence and drawing reasonable inferences in the light most favorable to the nonmoving party, we conclude that the policy at issue does not permit intra-policy stacking.
See Cooperman,
B
The subject policy is divided into six parts pertaining to liability coverage, medical payments coverage, uninsured/un-derinsured motorists coverage, auto damage coverage, insured’s duties after a loss, and general provisions. Part C, which concerns underinsured motorists coverage, contains a subsеction entitled “Limit of Liability” and provides as follows:
The limit of liability shown in the Declarations for “each person” for Uninsured/Underinsured Motorists Coverage is our maximum limit of liability for all damages including damages for care, loss of services ... arising out of bodily injury sustained by any one person in any one accident.
Subject to this limit for “each person,” the limit of liability shown in the Declarations for “each accident” for Uninsured/Undеrinsured Motorists Coverage is our maximum limit of liability for all damages for bodily injury resulting from any one accident. This is the most we will pay regardless of the number of: ... 3. Vehicles or premiums shown in the Declarations, (emphasis in original).
In the Declarations, the limit of liability shown for “each person” is $100,000. Part C unambiguously states that $100,000 is the maximum limit of underinsured motorists liability for all damages arising out of bodily injury sustained by any one person in any one accident, regardless of the number of vehicles or premiums shown in the Declarations. Complying with this provision, Safeco tendered $100,000 to Mena for damages arising out of the bodily injuries she suffered.
Mena contends, however, that the policy is ambiguous, and that construing it liberally in her favor, we should conclude that she is еntitled to up to $300,000 in underin-sured motorists coverage. She raises two arguments in support. 2 First, she contends that Part F of the policy, containing general provisions, creates an ambiguity with respect to Part C, and should leave us in doubt as to whether the policy in fact authorizes intra-policy stacking of underin- *1165 sured motorists coverage. Part F provides:
If this policy insures two or more autos or if any other аuto insurance policy issued to you by us applies to the same accident, the maximum limit of our liability shall not exceed the highest limit applicable to any one auto.
1. This provision does not apply to Uninsured/Underinsured Motorists Coverage.
Mena asserts that this language constitutes a clear anti-stacking provision that, by its terms, does not apply to underin-sured motorists coverage. Although Safe-co disputes that characterization, and explains the policy language differently, even accepting Mena’s version, she has not shown that the policy in any way authorizes stacking of underinsured motorists coverage. Liberally construed in Mena’s favor, this provision of Part F states that the maximum limit of liability fоr bodily injury or medical payment coverage is the highest limit applicable to any one auto, but that the provision does not apply to underinsured motorists coverage. Part F does not authorize, ambiguously or otherwise, stacking of underinsured motorists coverage; at most, it is an anti-stacking provision, applicable to both inter — and in-tra-poliсy stacking, that does not apply to uninsured or underinsured motorists coverage. Part C, however, contains clear and unambiguous anti-stacking language applying solely to underinsured and uninsured motorists coverage of multiple vehicles within the same policy. Part F leaves open whether stacking underinsured motorists coverage is forbidden with regard to intra-policy stacking; Part C answers that question unambiguously in the affirmative.
Secondly, Mena contends that when Part C refers to “[t]he limit of liability shown in the Declarations for ‘each person’ for Uninsured/Underinsured Motorists Coverage,” it is ambiguous whether the language refers to the “each person” limit for a single vehicle or to the sum of the three “each person” limits staсked together. On the declarations sheet, there is a column entitled “Limits” for each vehicle covered by the policy. For each of the vehicles, the limit for “Underinsured Motorists: Bodily Injury” is “$100,000 each person.” It is clear that the “each person” limit of liability shown in the Declarations for underinsured motorists coverage is $100,000. Adopting Mena’s view would require us to “tоrture” the policy’s language.
St. Paul Fire & Marine Ins. Co. v. Albany County Sch. Dist.,
Ill
The insurance policy at issue does not authorize intra-policy stacking of underin-sured motorists coverage. We therefore AFFIRM the district court’s order granting summary judgment to the defendants. We also DENY Appellant’s motion for certification of questions to the Wyoming Su *1166 preme Court. 4
Notes
. We stress that, unlike the present case, Ramsour involved multiple policies.
. Mena also argues that because the district court for the District of Montana decided against Safeco in a case raising similar issues, res judicata and collateral estoppel apply to this case.
See Moore v. Safeco,
. Because Safeco did not unreasonably or without cause refuse to pay, or delay payment of, the full amount it owed Mena, the district court correctly dismissed the case with prejudice notwithstanding Mena’s claim for attor
