CHIEF JUSTICE RICE delivered the Opinion of the Court.
¶ 1 As a passenger on a motorcycle, Doreen Heyboer was involved in an accident with an automobile in Denver and suffered catastrophic injuries. As a result of her injuries, her conservator sued the City and County of Denver, alleging that the streets deteriorated condition contributed to the accident. Denver responded by asserting its immunity under the Colorado Governmental Immunity Act (CGIA). Heyboer argues that Denver waived its immunity because the road was a dangerous condition that physically interfered with the movement of traffic, and thus, her suit fits an express exception found in the CGIA. § 24-10-106(1)(d)(I), C.R.S. (2017). Here, we review the court of appeals determination that Heyboer established a waiver of immunity.
¶ 2 We hold that Heyboers evidence did not establish a waiver of immunity. Specifically, we hold that her evidence did not establish that the road constituted an unreasonable risk of harm to the health and safety of the public, nor did her evidence establish that the road physically interfered with the movement of traffic. § 24-10-106(1)(d)(I) ; § 24-10-103(1.3), C.R.S. (2017). Accordingly, Denver retained its immunity under the CGIA, and we reverse the judgment of the court of appeals.
I. Facts and Procedural History
¶ 3 On September 20, 2013, Heyboer was a passenger on a motorcycle driven by Michael Veres. As they traveled eastbound on Mississippi Avenue, toward its intersection with Broadway, a westbound driver suddenly and unexpectedly turned left onto southbound Broadway, effectively cutting off Veres and Heyboer as they entered the intersection. Veres attempted to brake, but was unable to stop in time and collided with the rear panel of the turning car. Heyboer was flung from the motorcycle, landed on the pavement, and suffered permanent brain injuries. The driver of the car was cited for careless driving and failure to yield the right-of-way.
¶ 4 Through her conservator, Heyboer timely sued the City and County of Denver, alleging one count of negligence and one count of premises liability under section 13-21-115, C.R.S. (2017). Denver asserted that it was immune from suit under the CGIA and filed a motion to dismiss pursuant to C.R.C.P. 12(b)(1).
¶ 5 Pursuant to Trinity Broad. Corp. v. City of Westminster, 848 P.2d 916 (Colo. 1993), the district court held a hearing to decide the immunity question. At the hearing, Heyboer called William Kennedy, Denvers Pavement Engineer, to the stand. He testified that Denver would immediately repair a road if there was a condition on the road-such as a pothole, sinkhole, or lip-that might cause damage to a drivers car or force a driver to make an unnatural movement of their vehicle to avoid the obstacle. In order to determine when roads need repair, Denver uses a Pavement Condition Index (PCI). The PCI is a complex system which rates roads as excellent, good, fair, poor, or very poor. These ratings are not related to how safe or dangerous a road is, but rather assist Denver in determining maintenance-and-repair needs and priorities. While Denvers internal analysis rated the Mississippi-Broadway intersection as very poor, Kennedy testified that eight days before the accident, in response to a 311 complaint, he inspected the road and determined that while it was indeed cracked, worn, and somewhat rutted, it did not require immediate repair. Kennedy further testified that the intersection was dangerous, but not dangerous enough to warrant immediate repairs.
¶ 6 The district court, in a written order, found that Denver was immune from suit and dismissed the case. Specifically, the district court found that Heyboer produced no evidence, either through a witness or an exhibit, that this dangerous condition posed an unreasonable risk to the health or safety of the public as required by section 24-10-103(1.3).
¶ 7 In a unanimous opinion, the court of appeals reversed. Dennis ex rel. Heyboer v. City & Cty. of Denver, 2016 COA 140, ¶ 5, 419 P.3d 997. The court of appeals held that the district court clearly erred in its factual finding that the record contained no evidence of an unreasonable risk to the health or safety of the public. Id. at ¶ 4. The court of appeals determined that a plaintiff satisfies his or her burden of proving an unreasonable risk to the health or safety of the public under section 24-10-103(1.3) when he or she shows that a governmental entity failed to restore a damaged road to its same state of efficiency or repair as initially constructed. Id. at ¶ 36. Here, because the evidence showed the road was not maintained in the same state of repair or efficiency as initially constructed, the court of appeals held that the road constituted an unreasonable risk to the health or safety of the public. Id. at ¶¶ 39-40. Further, the court concluded that Heyboers evidence established that the road constituted a dangerous condition that interfered with the movement of traffic, meaning Denver waived its immunity under the CGIA. Id.
¶ 8 We granted certiorari and now reverse.
II. Standard of Review
¶ 9 This case was dismissed on a C.R.C.P. 12(b)(1) motion for lack of subject matter jurisdiction. Heyboer argues that immunity questions which implicate tort concepts should be judged by a more lenient standard, such as a C.R.C.P. 12(b)(5) standard or a summary judgment standard. We disagree. C.R.C.P. 12(b)(1) is the correct standard of review because whether the government is immune from suit is a jurisdictional question, and our case law requires that the district court make factual findings about its ability to hear the case.
¶ 10 The CGIA requires that once a public entity raises the defense of sovereign immunity, the court must immediately suspend discovery unrelated to sovereign immunity and decide that issue. § 24-10-108, C.R.S. (2017). Sovereign immunity must be dealt with at the earliest possible stage because [t]he sovereign cannot be forced to trial if a jurisdictional prerequisite has not been met. Trinity, 848 P.2d at 924. Because the CGIA protects the government from suit, the district court must necessarily make factual findings to ensure that the court has jurisdiction to hear the case. Trinity, 848 P.2d at 924. Accordingly, a C.R.C.P. 12(b)(1) standard of review is appropriate.
¶ 11 The burden of proof is on the plaintiff to prove the government has waived its immunity, but this burden is relatively lenient, as the plaintiff is afforded the reasonable inferences from her undisputed evidence. Tidwell ex rel. Tidwell v. City & Cty. of Denver, 83 P.3d 75, 85-86 (Colo. 2003). When the facts are disputed, the court must begin by making a factual finding. Id. If the court determines that the plaintiffs allegations are true, then it should award the plaintiff the reasonable inferences from her evidence. Id. at 85. However, because Trinity hearings are limited in nature, and because tort concepts are naturally subjective, the district court should not fully resolve the issue of whether the government has committed negligence; rather, the court should only satisfy itself that it has the ability to hear the case. Id. at 86 ; see also Swieckowski by Swieckowski v. City of Fort Collins, 934 P.2d 1380, 1384 (Colo. 1997) ([W]e emphasize that we do not address issues of negligence or causation, which are matters properly resolved by the trier of fact.).
¶ 12 We will uphold the factual determinations of the district court unless those determinations are clearly erroneous. Medina v. State, 35 P.3d 443, 452 (Colo. 2001). Once the questions of fact are resolved, we review questions of governmental immunity de novo. Id. at 452-53. When interpreting the statute, our focus is on legislative intent, and we construe the statute as a whole, giving consistent, harmonious, and sensible effect to all of its parts. St. Vrain Valley Sch. Dist. RE-1J v. Loveland, 2017 CO 54, ¶ 11, 395 P.3d 751, 754. We do not add or subtract words from the statute, and if the language is unambiguous, we give effect to its plain and ordinary meaning and look no further. Smokebrush Found. v. City of Colo. Springs, 2018 CO 10, ¶ 18, 410 P.3d 1236, 1240.
III. Analysis
¶ 13 Our analysis proceeds in the following way: First, we examine the dangerous condition prong of section 24-10-106(1)(d)(I), focusing on whether the road constituted an unreasonable risk to the health and safety of the public. We explain why we cannot affirm the court of appeals definition of unreasonable risk, and then define unreasonable risk. Applying that definition, we conclude that the road in this case did not constitute an unreasonable risk. Second, we examine the physical interference with traffic prong of section 24-10-106(1)(d)(I) and hold that the road did not physically interfere with the movement of traffic.
A. CGIA Background
¶ 14 The General Assembly enacted the CGIA in response to a trio of 1971 cases in which we held that common law sovereign immunity no longer applied in Colorado. Springer v. City & Cty. of Denver, 13 P.3d 794, 798 (Colo. 2000). The CGIA gives public entities immunity for injuries that lie in tort or could lie in tort. § 24-10-108, C.R.S. (2017). However, the CGIA waives immunity in certain circumstances. E.g., §§ 24-10-104 to - 106.3, C.R.S. (2017). Because the CGIA derogates common law, we construe its waivers of immunity broadly. Corsentino v. Cordova, 4 P.3d 1082, 1086 (Colo. 2000).
¶ 15 The CGIA waives a governmental entitys immunity when a dangerous condition of a ... road, or street ... physically interferes with the movement of traffic. § 24-10-106(1)(d)(I). Thus, in order to overcome Denvers motion to dismiss, Heyboer has the burden of proving to the district court that the road itself was a dangerous condition. The CGIA defines dangerous condition as:
a physical condition of a facility or the use thereof that constitutes an unreasonable risk to the health or safety of the public, which is known to exist or which in the exercise of reasonable care should have been known to exist and which condition is proximately caused by the negligent act or omission of the public entity or public employee in constructing or maintaining such facility.
§ 24-10-103(1.3). So, Heyboer must prove (1) the physical condition of the street, (2) constituted an unreasonable risk to the health or safety of the public, (3) Denver knew or should have known of the risk, and (4) Heyboers injury was proximately caused by Denvers negligent omission in maintaining the street. See St. Vrain, ¶ 16, 395 P.3d at 755 (enumerating the four factors that a plaintiff must generally prove to show a dangerous condition). Additionally, Heyboer had to demonstrate that the dangerous condition interfered with the movement of traffic. § 24-10-106(1)(d)(I).
¶ 16 Denver argues that Heyboer failed to demonstrate either element of section 24-10-106(1)(d)(I). First, Denver argues that the road did not present an unreasonable risk to the health and safety of the public, so the road did not present a dangerous condition. Second, Denver argues that the roads condition did not physically interfere with the movement of traffic. However, before we address these arguments, we first examine the court of appeals decision.
B. The Court of Appeals Erred
¶ 17 The court of appeals held that [t]he failure to keep a road in the same general state of repair or efficiency as it was initially constructed ... constitutes an unreasonable risk and that a plaintiff satisfies his or her burden of proving an unreasonable risk to the health or safety of the public under [ section] 24-10-103(1.3) when he or she shows that a governmental entity failed to restore a damaged road to its same state of efficiency or repair as initially constructed. Dennis, ¶ 36. The court applied its definition and concluded that Denver had, indeed, failed to maintain the road in the same condition as initially constructed, meaning Heyboer had established that the road was an unreasonable risk to the public. Id. at ¶ 39.
¶ 18 The court of appeals definition of unreasonable risk is incorrect for two reasons. First, the court of appeals misread the law. The governments duty to maintain a road is triggered only after the road becomes unreasonably dangerous. Swieckowski, 934 P.2d at 1385 ([W]hile the government has no duty to improve a roadway, it does have a duty to repair a roadway where the roadway has changed from its original condition and this change poses a danger.). It is only once the road becomes unreasonably risky that the government has a duty to take the steps necessary to return the road to the same general state of being, repair, or efficiency as initially constructed, but nothing more. Medina, 35 P.3d at 457. Just because a road is not like new does not mean it automatically constitutes an unreasonable risk to the health and safety of the public. Many perfectly safe roads are not in the same condition as they were on the day of construction. A road does not automatically constitute an unreasonable risk to the health and safety of the public merely because the government has failed to keep a road in the same general state of repair or efficiency as it was initially constructed. Dennis, ¶ 36. To the contrary, the CGIA and our prior case law make clear that the governments duty to maintain the road is triggered only once the road has degraded to such an extent that it presents an unreasonable risk to the public. Medina, 35 P.3d at 457 ; Swieckowski, 934 P.2d at 1385.
¶ 19 Second, when engaging in statutory construction, we construe statutes to further the legislative intent represented by the entire statutory scheme and avoid absurd results. State v. Nieto, 993 P.2d 493, 501 (Colo. 2000). Here, the court of appeals reading of the statute is at odds with the policy behind the CGIA itself. The CGIA was enacted, in part, to protect the taxpayers against excessive fiscal burdens which could arise from unlimited liability that the state could incur under tort lawsuits. § 24-10-102, C.R.S. (2017); see also Ceja v. Lemire, 154 P.3d 1064, 1067 (Colo. 2007) (One of the General Assemblys stated purposes in enacting the CGIA was to limit the liability of public entities and employees....). However, the court of appeals reading expands taxpayers fiscal burdens by creating an impossibly high standard. The court of appeals reading of the statute would require state and local governments to keep roads like new at all times, or face potential liability in a tort lawsuit because the road constitutes an unreasonable risk to the health and safety of the public. Statewide, the Colorado Department of Transportation (CDOT) estimates that maintaining mainline roads at this level would cost one billion dollars per year. Brief for Colorado Intergovernmental Risk Sharing Agency et al. as Amicus Curiae Supporting Petitioner, at 6. Further, restoring Colorados bridges to as constructed condition would cost an additional seven billion, with $360 million yearly for maintenance. Id. CDOTs yearly budget for fiscal year 2017 is $1.4 billion. Id. Of course, the state could not simultaneously fix every road; some roads would be prioritized and renovated before others. And when a motorist was injured on one of the non-prioritized roads that were awaiting renovation, the government would be potentially liable for not fixing the road. Thus, the taxpayers would be footing both the costs of making roads like new and the costs of potential lawsuits. The CGIA intends to lessen potential burdens on taxpayers; because the court of appeals ignored this policy declaration and expanded the potential burdens on taxpayers, the court of appeals erred. We now turn to the question of what unreasonable risk means for purpose of the CGIA.
C. Unreasonable Risk
¶ 20 Heyboer urges us to analyze unreasonable risk the same way that a court would analyze whether, in the tort context, a party owes a duty of care to another party. She argues that the legislature intended for the essence of the courts inquiry to be the same as the inquiry a court would undertake for a negligence claim that did not involve governmental immunity. Thus, Heyboer argues that a district court should only dismiss a complaint when the foreseeability of the risk is so remote in comparison to the magnitude of the burden in guarding against the risk ... that the defendant had no duty to guard against it as a matter of law.
¶ 21 We disagree. While one of the purposes of the CGIA is to permit a person to seek redress for personal injuries caused by a public entity, State v. Moldovan, 842 P.2d 220, 222 (Colo. 1992), the General Assembly did not intend suits against the government to be the same as normal negligence suits, because the CGIA explicitly limits governmental liability: [Governmental entities] should be liable for their actions and those of their agents only to such an extent and subject to such conditions as are provided by this article. § 24-10-102 (emphasis added). And the CGIA expressly states that aftersovereign immunity has been waived ... nothing shall be deemed to foreclose the assumption of a duty of care by a public entity or public employee. § 24-10-106.5(1). Thus, the court must decide the sovereign immunity question separate and apart from the duty of care question.
¶ 22 Further, when we construe statutes, we do not subtract words from the statute. Smokebrush, ¶ 18, 410 P.3d at 1240. Heyboers reading of the statute excises the word unreasonable from the statute. If a plaintiff needed to prove only that the risk was foreseeable, she would not also need to prove that the risk was unreasonable. There are situations when there is a chance the road could cause an injury, or it is foreseeable that the road could cause an injury, but that risk is inherent in driving on a road that has deteriorated from its original condition through use. Put differently, there is a foreseeable risk that the road could cause an injury, but that risk is reasonable. The CGIA requires more than a foreseeable risk of harm; it requires an unreasonable risk of harm. § 24-10-103(1.3).
¶ 23 Instead, to construe the statute, we look to the plain and ordinary meaning of the words in the statute. Smokebrush, ¶ 18, 410 P.3d at 1240. The CGIA defines dangerous condition as a condition that constitutes an unreasonable risk to the health or safety of the public. § 24-10-103(1.3). To determine the plain and ordinary meaning of words, we may look to the dictionary for assistance. People v. Voth, 2013 CO 61, ¶ 23, 312 P.3d 144, 149. Unreasonable in this context means exceeding the bounds of reason or moderation. Unreasonable, Websters Third New International Dictionary (unabr. ed. 2002). A risk is the chance of injury, damage, or loss. Risk, Blacks Law Dictionary (10th ed. 2014). The term unreasonable modifies the term risk. Therefore, to prove this element, the plaintiff must prove that the road condition created a chance of injury, damage, or loss which exceeded the bounds of reason. Determining if the road presents an unreasonable risk will necessarily be a fact-specific inquiry; there is no one-size-fits-all rule that encapsulates when a condition will constitute an unreasonable risk to the health and safety of the public. So, we now turn to the facts of this case.
D. Application
¶ 24 As the district court stated, the following is undisputed:
• [Heyboer] was injured in the motor vehicle crash which occurred at an intersection in Denver on September 20, 2013;
• Denver is responsible to maintain the road at this intersection; and
• Denver had notice of the condition of the roadway....
At the Trinity hearing, Heyboer and Denver called accident reconstruction experts to testify. The experts disagreed about whether the condition of the road caused the accident. Heyboer called the motorcycle driver to the stand, and he testified that the road may have played some role in his inability to avoid the accident. Denver called the investigating police officer, who testified that the road did not play a role in causing the accident. Thus, there was conflicting testimony on these points, and the district court did not make findings of fact resolving the conflicting testimony. Instead, the district court found that the road did not constitute an unreasonable risk to the health and safety of the public.
¶ 25 We agree. In this case, it may well be that driving on the road carried some risk-some chance of injury, damage or loss-however, we are not persuaded that the risk was unreasonable. In order for Denver to waive its immunity, the road must have degraded to such an extent that it was unreasonably risky, at which point in time Denver would be under a duty to fix the road by restoring the road to its design stage. Medina, 35 P.3d at 457 ; Swieckowski, 934 P.2d at 1385. Important to this determination is Kennedys unrebutted testimony. He testified that when determining if a road posed a risk to the health and safety of the public, he would look for deep, wide potholes that could catch a tire, or ruts that would cause a vehicle to be redirected and that those features were not present on this road. True, Kennedy testified that the road was well worn and in very poor condition at the time of the accident according to the PCI, but one week before this accident, Kennedy inspected the road and found that while it was cracked and rutted, it did not require immediate repair.
¶ 26 Here, the evidence did not show that the road posed a chance of injury, damage, or loss that exceeded the bounds of reason. The road, while cracked and rutted, did not contain potholes or sinkholes. The road did not contain features which would force a driver to make an emergency maneuver, or any other road characteristics such as a raised pavement lip that could damage a vehicle and lead to an accident. While Heyboer is afforded the inferences of her undisputed evidence, she nevertheless bore the burden of proving that the road constituted an unreasonable risk to the health and safety of the public; she failed to do so. Her evidence showed a deteriorated road, but not a road which was unreasonably risky on which to drive. Thus, Heyboer failed to establish that the road constituted a dangerous condition such that Denver waived its immunity under the CGIA.
¶ 27 We next examine whether the roads condition physically interfered with the movement of traffic. § 24-10-106(1)(d)(I). In determining that Denver had waived its immunity, the court of appeals held the district courts factual findings demonstrate[d] that the road conditions physically interfered with the movement of traffic on a road designed for public travel. Heyboer, ¶ 40. We disagree. Interfere means to interpose in a way that hinders or impedes. Interfere, Merriam-Webster Online Dictionary https://perma.cc/2DUH-HZAD. Physical means pertaining to real, tangible objects. Physical, Blacks Law Dictionary (10th ed. 2014). The condition may arise on the road itself, or from the governments failure to maintain a safety device. Moldovan, 842 P.2d at 225-28 (holding that the plaintiff proved a dangerous condition interfered with the movement of traffic when the state failed to repair a fence, a cow ran through the broken fence onto the road, and a motorcyclist collided with the cow). Thus, for this element to be satisfied, a dangerous condition of the road-or a defective safety device related to the road-must hinder or impede the flow of traffic.
¶ 28 Here, neither the road nor any defective safety device hindered or impeded the movement of traffic. Rather, the third-party driver impeded Veres and Heyboer by cutting them off. Before the third-party driver entered the intersection, there is no proof that the road itself caused the motorcycle to act erratically, or that the motorcycle was unable to drive safely on the road. There is no evidence that any safety device malfunctioned, nor any evidence that the roads surface, prior to the third-party drivers actions, prevented the motorcycle driver from preforming as expected. So, the road did not physically interfere with the movement of traffic.
IV. Conclusion
¶ 29 We reverse the judgment of the court of appeals, and we remand the case to that court for further proceedings consistent with this opinion.
JUSTICE GABRIEL dissents, and JUSTICE HOOD and JUSTICE HART join in the dissent.
We granted certiorari on the following three issues:
1. Whether the court of appeals holding that a public road constitutes an unreasonable risk to the health or safety of the public simply because it is not in the same state of repair or efficiency as initially constructed improperly removes respondents burden of proving the unreasonable risk and causation elements contained within the definition of a dangerous condition under the CGIA.
2. Whether the court of appeals erred by failing to require respondent to prove that the alleged state of disrepair of the road, itself, constituted a dangerous condition that physically interfered with the movement of traffic pursuant to section 24-10-106(1)(d)(I), C.R.S. (2016).
3. Whether the court of appeals erred by holding as a matter of law that a municipalitys failure to maintain a public road in its same state of repair or efficiency as initially constructed constitutes an unreasonable risk to the health or safety of the public pursuant to the definition of a dangerous condition set forth in section 24-10-103(1.3), C.R.S. (2016), of the Colorado Governmental Immunity Act (CGIA).
Heyboer also sued Veres, but the parties settled out of court. Heyboer settled with the driver of the other car without litigation.
311 is the non-emergency contact number which citizens can use to contact Denver regarding municipal facilities and services.
Under this standard, the court would accept every factual allegation in Heyboers complaint as true, and view the facts in the light most favorable to [Heyboer]. Norton v. Rocky Mountain Planned Parenthood, Inc., 2018 CO 3, ¶ 7, 409 P.3d 331, 334.
Under this standard, the court would grant Heyboer the benefit of all favorable inferences that may reasonably be drawn from the undisputed facts and resolve all doubts against [Denver]. Hardegger v. Clark, 2017 CO 96, ¶ 13, 403 P.3d 176, 180.
