DANIEL P. JORDAN, III, District Judge.
This negligence action is before the court on Defendants' Motion to Exclude Expert Opinion Testimony of Dane Maxwell  and Motion in Limine to Exclude Evidence Related to George M. Bryant's Log Books . The Court, having considered the memoranda and submissions of the parties along with the pertinent authorities, and having discussed the motions with counsel at the pretrial conference, finds that both motions should be granted.
I. Facts and Procedural History
This cases arises from a December 7, 2010 traffic accident on Highway 49 in Rankin County, Mississippi. Defendant George M. Bryant was driving a commercial truck and rearended Plaintiff Donald Raglin's vehicle which had stopped to make a right turn. Bryant was operating the vehicle in the scope of his employment by Defendant MSJ Trucking, Inc. Raglin alleges he suffered injuries from the collision and filed a complaint on July 27, 2012, alleging negligence. Raglin designated Dane Maxwell as an expert witness. Defendants moved to exclude his testimony under Federal Rule of Evidence 702. Defendants also moved to exclude evidence that Bryant committed various log book violations.
The district court fulfills a gatekeeper function to exclude irrelevant or unreliable expert testimony. Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 589 & n.7 (1993). This function begins with Rule 702 of the Federal Rules of Evidence, which regulates admission of expert testimony. The rule provides:
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
Fed. R. Evid. 702.
Whether a proposed expert should be permitted to testify under Rule 702 "is case, and fact, specific." Hodges v. Mack Trucks Inc., 474 F.3d 188, 194 (5th Cir. 2006) (citation omitted). Thus, the district court retains "broad latitude' both in deciding how to determine whether an expert's testimony is reliable, and ultimately, whether the testimony is, in fact, reliable." Id. (quoting Kumho Tire Co. v. Carmichael, 526 U.S. 137, 142 (1999)). "The party offering the expert must prove by a preponderance of the evidence that the proffered testimony satisfies the rule 702 test." Mathis v. Exxon Corp., 302 F.3d 448, 459-60 (5th Cir. 2002).
The gatekeeper function of the district court does not, however, replace trial on the merits. In performing this function, the district court should approach its task "with proper deference to the jury's role as the arbiter of disputes between conflicting opinions. As a general rule, questions relating to the bases and sources of an expert's opinion affect the weight to be assigned that opinion rather than its admissibility and should be left for the jury's consideration." United States v. 14.38 Acres of Land, 80 F.3d 1074, 1077 (5th Cir. 1996) (quoting Viterbo v. Dow Chem. Co., 826 F.2d 420, 422 (5th Cir. 1987)).
Defendants seek to exclude Maxwell's testimony because it is unreliable and irrelevant, will not assist the trier of fact, and Maxwell is not qualified to give the proposed opinion. According to Maxwell's Opinion Report and Plaintiff's Designation of Expert Witnesses, he intends to testify that Bryant committed various violations of the Federal Motor Carrier Safety Regulations (FMCSR). His opinion is that these violations caused the traffic accident because based on the violations, MSJ should have placed Bryant "out of service" and he should not have been driving at the time of the accident. Raglin also offers Maxwell to testify that Bryant manipulated log books to hide excessive speed, and had he driven slower on earlier legs of the trip he would not have been at the scene of the accident when Raglin arrived.
Though the parties spend considerable time on qualifications and methodology under Rule 702, the Court concludes that the opinions lack relevance and are not admissible under Federal Rules of Evidence 401, 402, or 403. In general terms, the various FMCSR violations upon which Maxwell relies were not the proximate cause of the accident. Maxwell's testimony is therefore ...
