MEMORANDUM AND ORDER

This matter comes before the Court on Defendants Keep Trucking, LLC and MDJ Trucking Logistics, LLC’s Motion for Summary Judgment (ECF No. 44), Defendant Marcus D. Jethrow’s Motion for Summary Judgment (ECF No. 47), Plaintiff’s Motion to Exclude the Opinions and Testimony of Expert Kevin Johnson (ECF No. 51), and Defendants’ Motion to Strike (ECF No. 63). All motions have been fully briefed. The parties have consented to the jurisdiction of the undersigned United States Magistrate Judge pursuant to Title 28 U.S.C. § 636(c). I. BACKGROUND On September 30, 2021 at approximately 4:14 p.m., Defendant Marcus D. Jethrow (Defendant Jethrow), was operating a 2021 Volvo 760 tractor-trailer owned by Defendant Keep Trucking, LLC (Defendant Keep Trucking) traveling northbound on US 61 Hwy in Marion County, Missouri. At the same time, Mr. Keith Triplett (decedent) was operating a 1988 International Harvester grain hauler traveling east on County Road 338 in the process of crossing US 61 Hwy. The vehicles collided, and Mr. Triplett died as a result. On September 30, 2024, Mr. Triplett’s wife, Plaintiff Kimberly Triplett, as representative of the wrongful death class of decedent, filed a petition in Marion County, Missouri, asking for actual and punitive damages, and asserting claims of (1) vicarious liability against the Defendants Keep Trucking and MDJ Trucking under respondeat superior; (2) negligence in

hiring, training, supervising, retaining, and entrusting Jethrow against Defendant Keep Trucking; (3) negligence per se based on alleged violations of Federal Motor Carrier Safety Regulations and a Missouri statute against all Defendants; and (4) negligence against Defendant Jethrow. Plaintiff then removed this matter to federal court. II. SUMMARY JUDGMENT LEGAL STANDARD Summary judgment shall be granted “if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). In ruling on a motion for summary judgment, the Court is required to view the evidence in the light most favorable to the non-moving party and must give that party the benefit of all reasonable inferences to be drawn from the underlying facts. Lombardo v. City of St. Louis, 38

F.4th 684, 689 (8th Cir. 2022). The moving party bears the initial burden of showing both the absence of a genuine issue of material fact and entitlement to judgment as a matter of law. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250 (1986); Fed. R. Civ. P. 56(a). If the movant does so, “the nonmovant must respond by submitting evidentiary materials that set out specific facts showing that there is a genuine issue for trial.” Gannon Int’l, Ltd. V. Blocker, 684 F.3d 785, 792 (8th Cir. 2012) (citing Torgerson v. City of Rochester, 643 F.3d 1031, 1042 (8th Cir. 2011) (en banc)). Rule 56(c) “mandates the entry of summary judgment, after adequate time for discovery and upon motion, against a party who fails to make a showing sufficient to establish the existence of an element essential to that party's case, and on which that party will bear the burden of proof at trial.” Celotex Corp. v. Catrett, 477 U.S. 317, 322 (1986). “[A] properly supported motion for summary judgment is not defeated by self-serving affidavits.” Conolly v. Clark, 457 F.3d 872, 876 (8th Cir.2006) (citing Davidson & Assocs. v. Jung, 422 F.3d 630, 638 (8th

Cir.2005)). The nonmovant “must provide more than conjecture and speculation.” Rusness v. Becker Cnty., 31 F.4th 606, 614 (8th Cir. 2022). Self-serving, conclusory statements without support are insufficient to defeat summary judgment. Viewpoint Neutrality Now! v. Bd. of Regents of Univ. of Minn., 109 F.4th 1033, 1038 (8th Cir. 2024). “An issue of fact is genuine when ‘a reasonable jury could return a verdict for the nonmoving party’ on the question.” Woods v. DaimlerChrysler Corp., 409 F.3d 984, 990 (8th Cir. 2005) (quoting Anderson, 477 U.S. at 248). “A fact is material if it ‘might affect the outcome of the suit.’” Dick v. Dickinson State Univ., 826 F.3d 1054, 1061 (8th Cir. 2016) (quoting Anderson, 477 U.S. at 248). Though the Court is “required to make all reasonable inferences in the non- movant's favor while reviewing the alleged facts, we are not required to ‘accept unreasonable

inferences or sheer speculation as fact.’” Maser v. City of Coralville, Iowa, 139 F.4th 1004, 1008 (8th Cir. 2025) (quoting Gilani v. Matthews, 843 F.3d 342, 349 (8th Cir. 2016)). “In reaching its decision, a court should not weigh the evidence, make credibility determinations, or attempt to determine the truth of the matter.” Leonetti's Frozen Foods, Inc. v. Rew Mktg., Inc., 887 F.3d 438, 442 (8th Cir. 2018) (internal quotation marks omitted). III. UNDISPUTED MATERIAL FACTS1 On September 30, 2021, Defendant Jethrow was the driver of a 2021 Volvo 760 tractor- trailer. Defendant Jethrow was driving northbound on US 61 Hwy in Marion County, Missouri.

1 The following facts are taken from the parties’ statements of uncontroverted material facts and responses to such and are undisputed except where indicated. At the same time, decedent Keith Triplett was driving a grain hauler east on County Road 338 in Marion County, Missouri in the process of crossing US 61 Hwy. Defendant Jethrow had the right of way as he was traveling northbound on US 61 Hwy. Decedent had the yield sign and failed to yield to oncoming traffic. Plaintiffs agree that anyone crossing US 61 Hwy must yield to traffic

traveling in the northbound lanes of US 61 Hwy. Defendant Jethrow testified that he noticed decedent’s grain hauler at the stop sign on the other side of the southbound lanes approximately ten seconds before the collision, maybe less. Defendant Jethrow then passed another tractor- trailer also traveling northbound on US 61 Hwy. Defendant Jethrow’s tractor-trailer collided with decedent’s grain hauler when decedent crossed onto US 61 Hwy, resulting in the death of decedent. On September 30, Defendant Jethrow was acting within the course and scope of his employment. He was a commercial driver of approximately twenty years and in that time, had been involved in no accidents. His tractor-trailer was equipped with a video camera and Samsara ECM (engine control module which captures speed, throttle, and braking data) and ELD

(electronic logging device which tracks a driver’s hours of service). Defendant Keep Trucking used Samsara as its ELD service provider. The ELD system had an alert mechanism that notifies the carrier when a driver exceeds allotted drive time.
