delivered the opinion of the Court.
Respondents’ motion for rehearing is overruled. Our opinion of May 8, 1998, is withdrawn and the following is substituted in its place.
This is a suit for injuries arising out of the abuse of children at a day care center. Plaintiffs filed suit individually and as next friends of their two children, alleging that defendants witnessed the abuse and failed to report it to the police or child welfare officials. The sole issue before us is whether plaintiffs may maintain a cause of action for negligence per se based on the Family Code, which requires any person having cause to believe a child is being abused to report the abuse to state authorities and makes the knowing failure to do so a misdemeanor.
See
Tex. Fam.Code §§ 261.101(a), 261.109 (formerly Tex. Fam.Code §§ 34.01, 34.07). The trial court granted summary judgment for defendants, but the court of appeals reversed and remanded plaintiffs’ negligence per se and gross negligence claims for trial.
Nash v. Perry,
B.N. and K.N. attended a day care center operated by Francis Keller and her husband Daniel Keller from March 25, 1991, to August 28, 1991. Their parents, S.N. and S.N., allege that during that period, Daniel Keller regularly abused B.N. and K.N. and other children at the center both physically and sexually. Mr. and Mrs. N. brought suit against the Kellers and three of the Kellers’ friends, Douglas Perry, Janise White, and Raul Quintero. Plaintiffs claim that Francis Keller confided in White at an unspecified time that Daniel Keller had “abusive habits toward children.” They further allege that on one occasion in August 1991, while visiting the Kellers, defendants Perry, White, and Quintero all saw Daniel Keller bring a number of children out of the day care center into the Kellers’ adjoining home and sexually *303 abuse them. The record does not indicate whether B.N. and K.N. were among these children. According to plaintiffs, Perry, White, and Quintero did not attempt to stop Daniel Keller from abusing the children or report his crimes to the police or child welfare authorities.
Plaintiffs’ brief filed in this Court alleges additional facts that were not contained in their trial court pleadings. They now assert that Perry pleaded guilty to indecency with a child by contact and that White and Quintero were indicted but not prosecuted for sex offenses involving the children at the day care center. Plaintiffs’ trial court petition, however, did not allege that Perry, White, or Quintero participated in abusing B.N. and K.N. or other children. We may not consider factual assertions that appear solely in the appellate briefs and not before the trial court.
See Estate of Arrington v. Fields,
Instead, Mr. and Mrs. N. alleged only that Perry, White, and Quintero were negligent per se because they violated a statute requiring any person who “has cause to believe that a child’s physical or mental health or welfare has been or may be adversely affected by abuse” to file a report with the police or the Department of Protective and Regulatory Services. Tex. Fam.Code § 261.109(a). Plaintiffs also asserted gross negligence and common law negligence claims. They claimed that Perry, White, and Quintero’s failure to report the abuse proximately caused them harm by permitting the day care center to remain open, thus enabling Daniel Keller to continue abusing the children at the center. They sought damages for pain, mental anguish, and medical expenses, as well as loss of income when they could not work outside the home because of B.N. and K.N.’s injuries.
Perry, White, and Quintero moved for summary judgment on the sole ground that plaintiffs failed to state a cause of action. None of the parties presented any summary judgment evidence. A court may not grant summary judgment for failure to state a cause of action without first giving the plaintiff an opportunity to amend the pleadings.
See Pietila v. Crites,
The trial court granted Perry, White, and Quintero’s motions for summary judgment and severed plaintiffs’ claims against those three defendants from their suit against the Kellers, which is not before us. Because defendants’ motions for summary judgment argued only that plaintiffs failed to state a cognizable claim, the trial court’s judgment can be upheld, if at all, only on that ground.
See McConnell v. Southside Indep. Sch. Dist.,
The court of appeals affirmed the summary judgment on plaintiffs’ common law negligence claims but reversed and remanded for trial on the issues of negligence per se and gross negligence, holding that a violation of the Family Code’s child abuse reporting requirement is negligence per se.
“It is fundamental that the existence of a legally cognizable duty is a prerequisite to all tort liability.”
Graff v. Beard,
A person having cause to believe that a child’s physical or mental health or welfare has been adversely affected by abuse or neglect by any person shall immediately make a report as provided by this sub-chapter.
Tex. Fam.Code § 261.101(a). 2
(a) A person commits an offense if the person has cause to believe that a child’s physical or mental health or welfare has been or .may be adversely affected by abuse or neglect and knowingly fails to report as provided in this chapter.
(b) An offense under this section is a Class B misdemeanor.
Id.
§ 261.109.

The court concluded that these provisions create a “statutory duty” to report child abuse, and that a violation of this duty is negligence per se.
See
All persons have a duty to obey the criminal law in the sense that they may be prosecuted for not doing so, but this is not equivalent to a duty in tort.
See, e.g., Smith v. Merritt,
Before we begin our analysis of whether section 261.109 of the Family Code is an appropriate basis for tort liability, we emphasize that we must look beyond the facts of this particular case to consider the full reach of the statute. We do not decide today whether a statute criminalizing only the type of egregious behavior with which these defendants are charged—the failure of eyewitnesses to report the sexual molestation of preschool children—would be an appropriate basis for a tort action. That is not the statute the Legislature passed. Rather, the issue before us is whether it is appropriate to impose tort liability on any and every person who “has cause to believe that a child’s physical or mental health or welfare has been or may be adversely affected by abuse or neglect and knowingly fails to report.” Tex. Fam.Code § 261.109(a). Cf. Leonard, The Application of Criminal Legislation to Negligence Cases: A Reexamination, 23 Santa Claha L.Rev. 427, 457-66 (1983) (contrasting the rigidity of statutory standards with the flexibility of case-by-case common law determinations of duty and breach).
The threshold questions in every negligence per se ease are whether the plaintiff belongs to the class that the statute was intended to protect and whether the plaintiffs injury is of a type that the statute was designed to prevent.
See Moughon v. Wolf,
B.N. and K.N. are within the class of persons whom the child abuse reporting statute was meant to protect, and they suffered the kind of injury that the Legislature intended the statute to prevent.

But this does not end our inquiry.
See Praesel v. Johnson,
We first consider the fact that, absent a change in the common law, a negligence per se cause of action against these defendants would derive the element of duty solely from the Family Code. At common law there is generally no duty to protect another from the criminal acts of a third party or to come to the aid of another in distress.
See Butcher,
In contrast, the defendant in most negligence per se cases already owes the plaintiff a pre-existing common law duty to act as a reasonably prudent person, so that the statute’s role is merely to define more precisely what conduct breaches that duty.
See Rudes,
When a statute criminalizes conduct that is also governed by a common law duty, as in the case of a traffic regulation, applying negligence per se causes no great change in the law because violating the statutory standard of conduct would usually also be negligence under a common law reasonableness standard.
See Praesel,
Some commentators contend that the term “negligence per se” does not even apply when the statute on which civil liability is based corresponds to no common law duty.
See
Keeton et al. § 36, at 221 n. 9; Forell,
The Statutory Duty Action in Tort: A Statutory/Common Law Hybrid,
23 Ind. L.Rev. 781, 782 (1990). While our definition has never been so restrictive, this Court in fact
*307
has created a new duty by applying negligence per se on only one occasion. In
Nixon v. Mr. Property Management Co.,
The court of appeals in this ease listed several factors to consider in deciding whether to apply negligence per se. See 944 5.W.2d at 730 (citing Ratliff, Comment, Negligence Per Se in Texas, 41 Tex. L.Rev. 104, 106 (1962)). According to the court of appeals, the principal factors favoring negligence per se are that the Legislature has determined that compliance with criminal statutes is practicable and desirable and that criminal statutes give citizens notice of what conduct is required of them. See id. As considerations against negligence per se, the court of appeals cautioned that some penal statutes may be too obscure to put the public on notice, may impose liability without fault, or may lead to ruinous monetary liability for relatively minor offenses. See id. The first of these factors is not helpful because it points the same way in every case: the very existence of a criminal statute implies a legislative judgment that its requirements are practicable and desirable. The court of appeals’ remaining factors, however, are pertinent to our analysis.
On the question of notice, this Court has held that one consideration bearing on whether to apply negligence per se is whether the statute clearly defines the prohibited or required conduct.
See Praesel,
The next factor thé court of appeals considered was whether applying negligence per se to the reporting statute would create liability without fault.
See
Our next consideration is whether negligence per se would impose ruinous liability disproportionate to the seriousness of the defendant’s conduct. In analyzing this factor, the court of appeals treated child abuse as the relevant conduct.
See
Finally, in addition to the factors discussed by the court of appeals, we have also looked to whether the injury resulted directly or indirectly from the violation of the statute.
See Praesel,
The lack of direct causation is not in itself dispositive; we have imposed civil liability for some statutory violations that caused the plaintiffs injury by facilitating the tort of a third party.
See El Chico,
We conclude by noting that for a variety of reasons, including many of those we have discussed, most other states with mandatory reporting statutes similar to Texas’s have concluded that the failure to report child abuse is not negligence per se.
See C.B. v. Bobo,
In summary, we have considered the following factors regarding the application of negligence per se to the Family Code’s child abuse reporting provision: (1) whether the statute is the sole source of any tort duty from the defendant to the plaintiff or merely supplies a standard of conduct for an existing common law duty; (2) whether the statute puts the public on notice by clearly defining the required conduct; (3) whether the statute would impose liability without fault; (4) whether negligence per se would result in ruinous damages disproportionate to the seriousness of the statutory violation, particularly if the liability would fall on a broad and wide range of collateral wrongdoers; and (5) whether the plaintiffs injury is a direct or indirect result of the violation of the statute. Because a decision to impose negligence per se could not be limited to cases charging serious misconduct like the one at bar, but rather would impose immense potential liability under an ill-defined standard on a broad class of individuals whose relationship to the abuse was extremely indirect, we hold that it is not appropriate to adopt Family Code section 261.109(a) as establishing a duty and standard of conduct in tort. Therefore, Mr. and Mrs. N. and their children may not maintain a claim for negligence per se or gross negligence based on defendants’ violation of the child abuse reporting statute. Because plaintiffs did not appeal the court of appeals’ adverse decision on their common law negligence claims, we do not consider whether Texas should impose a common law duty to report or prevent child abuse.
For the foregoing reasons, we reverse the judgment of the court of appeals and render judgment that plaintiffs take nothing.
Notes
. This Court was unable to address the negligence per se issue in
Butcher
for jurisdictional reasons.
See Butcher v. Scott,
. This mandatory reporting statute was enacted in 1971. See Act of May 24, 1971, 62d Leg., R.S., ch. 902, § 1, 1971 Tex. Gen. Laws 2790, 2791. Prior to that time, Texas did not require the reporting of child abuse, although there were statutes granting immunity from suit to doctors and other professionals who chose to report cases of suspected abuse. See Act of April 26, 1965, 59th Leg., R.S., ch. 117, 1965 Tex. Gen. Laws 277 (physicians); Act of May 5, 1969, 61st Leg., R.S., ch. 219, 1969 Tex. Gen. Laws 637 (other professionals).
The version of this provision in force at the time of the events in this case read "has been
or may be
adversely affected.”
See
. This provision criminalizing the failure to report was added in 1973. See Act of May 17, 1973, 63d Leg., R.S., ch. 398, § 1, 1973 Tex. Gen. Laws 881.
. At times, our opinions have included language suggesting that any statutory violation is automatically negligence per se.
See, e.g., Southern Pac. Co. v. Castro,
. A few courts in other jurisdictions have interpreted mandatory reporting statutes as intended to protect only the specific child the defendant suspects is being abused, not other potential victims of the same abuser.
See Curran v. Walsh Jesuit High School,
. Determining whether abuse is or may be occurring in a particular case is likely to be especially difficult for untrained laypersons. Texas is one of a minority of states that require any person who suspects child abuse to report it. See O'Brien & Flannery, The Pending Gauntlet to Free Exercise: Mandating that Clergy Report Child Abuse, 25 Loy. L.A. L.Rev. 1, 24-25 & n. 127 (1991) (collecting statutes). Most states place such a requirement only on professionals who may be expected to know more than the average person about recognizing child abuse and who have a professional relationship with and responsibility for children. See id. at 19 n. 106 (collecting statutes); id. at 24. The Texas Family Code contains a separate mandatory reporting provision, not relevant here, specifically directed to members of certain professions. See Tex. Fam. Code § 261.101(b).
. We do not mean to suggest that section 261.109 is unconstitutionally vague. In fact, one court of appeals has already rejected an as-applied vagueness challenge to this provision.
See Morris v. State,
. Although the issue of strict liability is related to the problem of notice,
