MEMORANDUM OPINION AND ORDER GRANTING PLAINTIFF’S MOTION TO STRIKE THE TESTIMONY OF DR. BANKS
Now before the Court is the Plaintiffs Motion to Strike the Testimony of Dr. Robert Banks. (Doc. # 68). The Court, after careful consideration of the pleadings and the applicable law, and after hearing the argument of counsel, hereby finds Plaintiffs motion well taken.
I. Background
This products liability lawsuit arises from an automobile accident that occurrеd on June 16, 1997. According to Plaintiffs Complaint, Betty and Raymond Milbrand were traveling south on Interstate Highway 40 in a 1997 Dodge Ram 1500 when the “rear axle sheared off the right rear wheel” causing Raymond Milbrand to lose control of the vehicle. The vehicle veered off the highway, rolled over four to five times, and came to rest on its side. It is undisputed that Raymond Milbrand was unbelted at the time of the accident and that he was ejected during the rollover. Mr. Milbrand died at the accident scene. Mrs. Milbrand brought this suit alleging that a defect in the rear axle of the Dodge Ram 1500 caused the accident which resulted in her injuries and in her husband’s death.
DaimlerChrysler Corporation (“Daimler-Chrysler”) offered the testimony of Dr. Robert D. Banks, a medical doctor and engineer, on issues related to biomechan-ics, occupant kinematics, and injury causa *604 tion. Dr. Banks was retained by counsel for DaimlerChrysler to form an opinion about whether Mr. Milbrand’s injuries would have been different if he had not been ejected from his vehiclе. On April 27, 2000, Plaintiff filed a Motion to Exclude the Testimony of Dr. Banks and in particular any testimony about whether Mr. Mil-brand failed to wear a seat belt. Plaintiff contends that such evidence is strictly inadmissible under Texas Transportation Code § 545.413(g). Defendant filed its reply brief on May 16, 2000 arguing 1) that federal, not Texas law applies to the admissibility of seat belt evidence; 2) if Texas law applies, such evidence is admissible as to causation; and 3) if Texas law applies and seat belt evidence is not admissible on the issue of causation, then the statute is unconstitutional under the due process and equal protection provisions of the Texas and United States Constitutions.
II. Discussion
A. Tеxas Transportation Code § 545.413(g) is a Substantive Rule of Law
The court must first make a threshold decision as to whether Texas Transportation Code § 545.413(g) is procedural or substantive in nature. This is an issue of first impression in the Fifth Circuit.
1
It is well settled that in diversity cases a federal court applies the substantive law of the jurisdiction in which it is sitting and federal рrocedural law.
See Erie R.R. Co. v. Tompkins,
Because Texas’s statute prohibits a defendant from introducing evidence of seat belt nonuse in civil trials, a decision by this Court to treat the Texas statute as procedural would likely encourage federal forum shopping in cases where the plaintiff was not wearing a seat belt. The introduction or exclusion of the seat belt evidence also impacts the amount of blame apportioned by the fact finder thus effecting the outcome of the litigation in a significant way. Therefore, employing federal law in this case would violate the underlying policies of Erie.
In reaching the conclusion that the Texas statute establishes a rule of substantive law, the Court finds persuasive the fact that the provision is part of the Texas Transportation Code and Texas’s mandatory seat belt law. The law places a legal duty upon specified persons to wear a seat belt, provides for fines where that duty is breached, and provides that use оr nonuse of a seat belt is not admissible evidence in a civil trial. The Texas statute is clearly designed to regulate the behavior of individuals outside of the courtroom and consequently falls on the substantive side of the
Erie
line. Texas, like many other state courts,
2
debated the use of seat belt evidence and its impact on personal injury litigation, an area governed primarily by state law.
See
Peter Scaff, Comment,
The Final Piece of the Seat Belt Evidence Puzzle,
36 Hous. Law Rev. 1371, 1373 (1999). The Texas legislature ultimately replaced
*605
various common law decisions with a clear-cut rule excluding evidence of the use or nonuse of a seat belt in a civil trail.
See id.
at 1374. Texas’s statute modifies state tort law and is a “classic example of the type of substantive rule of law binding uрon a federal court in a diversity case.”
Potts v. Benjamin,
The Court also finds support for its decision in a number of circuit court opinions that have found similar statutes to be substantive.
InGardner v. Chrysler Corp.,
B. Tex. Trans. Code § 545.413(g) Bars The Introduction of Dr. Banks’s Testimony
It has long been settled in Texas that Plaintiffs “should not have the damages awarded to them reduced or mitigated because of their failure to wear available seat belts.”
Carnation Company v. Wong,
In
Pool v. Ford Motor Co.,
In 1994, the Texas Supreme Court reconsidered the' Texas seat belt statute in the case of
Bridgestone/Firestone v. Glyn-Jones,
Relying on “the flip-side” of Bridge-stone/Firestone, DaimlerChrysler argues that the Texas statute was not intended to deprive a defendant manufacturer of the ability to rebut a plaintiffs allegations on the elements of defect, causation, and/or damages. Defendant’s reliance is misplaced. The Bridgestone/Firestone Court narrowly held that the seat belt statute does not apply when evidence of seat belt use is offered by a plaintiff against a seat belt manufacturer. See id.; see also Seaff, supra at 1403. Furthermore, Bridge-stone/Firestone was a crashworthiness case; this case is not. In a crashworthiness case, a plaintiff does not seek compensation for injuries received from the initial collision between the vehicle and another object. Instead, the plaintiff seeks compensation for injuries that occur when the plaintiff strikes the interior of the vehicle or is thrown from the vehicle. In a crashworthiness claim, plaintiff seeks compensation for injuries over and above the injury that would have occurred as a result of the impact of collision, absent the vehicle’s alleged negligently defective design. In this case, Mrs. Milbrand is not alleging that the vehicle failed to reduce or prevent the injuries suffered becausе of a defect in its safety related features. Instead, this is a traditional product liability case where the issue is whether or not a defect caused the accident.
While there may be some debate as to whether the statute at issue applies in a crashworthiness case such as
Bridge-stone/Firestone,
the Texas Supreme Court has clearly indicated that the statute bars the admission of seat belt evidence on the issue of contributory negligence as a matter of law in non-crashworthiness product liability cases.
See Pool,
Defendant’s argument that even if evidence of seat belt nonuse cannot be used tо establish negligence or to reduce damages, that it may be used to negate a determination of proximate causation likewise fails. Of the three cases Daimler-Chrysler cites in support of its position,
3
only one,
MacDonald v. General Motors Corp.,
*607
Texas Courts have not yet addressed the issue of whether evidence of seat belt nonuse is admissible for the limited purpose of negating proximate cause. This Court, having determined that the Texas Statute is a substantive statute, must look to the Texas Supreme Court’s decisions and make an
“Erie
guess” to determine how the Texas Supreme Court would decide the issue.
Howe Ex Rel. Howe v. Scottsdale Ins. Co.,
C. DaimlerChrysler Has Not Shown that the Texas Statute is Unconstitutional
DaimlerChrysler argues that to the extent that Texas Law prevents it from submitting evidence that Mr. Milbrand was not wearing his seat belt, its State and Federal Constitutional Rights of Due Process and Equal Protection are violated. DaimlerChrysler fails to meet its burden of demonstrating that the Texas statute is unconstitutional.
The analysis of the constitutionality of a statute under the equal protection clause of the United States and Texas Constitution is the same.
See Lucas v. United States,
DaimlerChrysler is not a member of a suspect or sensitive class. These categories have been reserved for classifications based on race, national origin, gender and alienage.
See id.
at 704. Nor has DaimlerChrysler identified any fundamental or important right upon which this statute infringes. The right to assert the seat belt defense is not the type of important, vested right so as to warrant a level of heightened scrutiny, a conclusion supported by the fact that evidence of seat belt nonuse was not permitted even prior to the adoption of the Texas Statute.
See Bridgestone/Firestone,
Under the rational basis test, there is a strong presumption that the statute is constitutional.
See Heller v. Doe,
DaimlerChrysler’s Federal due process argument likewise fails. Under federal due process analysis, legislative acts have a presumption of constitutionality and the burden is on the party com
*608
plaining of the violation to show that the legislature has acted in an arbitrary and irrational way.
See Duke Power v. Carolina Environ. Study,
III. Conclusion
The Texas seat belt statute represents the substantive policy of the State of Texas regarding evidence of the use or nonuse of a seat belt in a civil case. Accоrding to the Erie Doctrine, this federal court sitting in Texas is bound to apply this substantive law. The Texas seat belt statute expressly prohibits evidence of the use or nonuse of a seat belt in a civil action for any purpose. The only exception is where the cause of action is based upon an allegation that the seat belt used was defective. There is no such allegation in this case. Therefore, DaimlerChrysler is not entitled to introduce evidence regarding the fact that Mr. Milbrand was not wearing his seat belt at the time of the accident at issue in this case. DaimlerChrysler has also failed to meet its burden regarding its claims that the Texas seat belt statute is unconstitutional. It is therefore
ORDERED, ADJUDGED, and DECREED, that Plaintiffs Motion to Strike the Testimony of Dr. Robert Banks, M.D. is GRANTED. It is further
ORDERED, ADJUDGED, and DECREED that the any evidence concerning the use or nonuse of seat belts by either Mr. or Mrs. Milbrand shall be excluded.
Notes
. Although this Circuit has not directly ruled on the application of § 545.413(g), it has had occasion to find a forum state's law controlling whеn considering the admissibility of seat belt evidence.
See Hermann v. General Motors Corp.,
. Many states have chosen to reject the "seat belt defense” through judicial decision or legislation. See Recent Case, 102 Harv. L.Rev. 925, 929 n. 37 (1989)(stating many states statutes expressly prohibit the use of the seat belt defense).
. Defendant cites
Barron v. Ford Motor Company,
. While the Court does not address whether the Texas statute is constitutional, it is worth noting that similar statutes have been found constitutional. See Kelly v. Ford, 1996 U.S. Dist. Lexis 16240.
