    This case comes before us on an appeal of the trial court’s grant of summary judgment in favor of
    the defendants. Because the plaintiffs have established the existence of several genuine issues of
    material fact, we conclude that summary judgment is inappropriate. We further conclude that the trial
    court did not err in excluding evidence of a defendant’s subsequent remedial measures. We therefore
    reverse the trial court’s judgment and remand for further proceedings.

    OPINION
    I. Factual and Procedural History
    A.
    This case arises out of the tragic death of Kathryn Martin, who was killed when her vehicle
    was hit by a train. The following facts about the incident are undisputed.
    The collision occurred on May 12, 2002, at approximately 9:00 a.m. On that day, the weather
    was clear, and there was no rain. Mrs. Martin was operating her pickup truck northward on Marlow
    Circle, a road leading into the parking lot of Moran Baptist Church. Norfolk Southern Railway
    Company (“Norfolk”) maintains railroad tracks that intersect this section of Marlow Circle. The
    railroad crossing at that location is of a type commonly described as a passive crossing–that is, it
    does not contain any traffic control devices that activate when a train is approaching. Rather, the
    crossing is marked with crossbuck signs warning motorists that a railroad crossing is ahead. In
    addition, the crossing consists of two separate tracks: a mainline track, which carries regular train
    traffic; and a storage track, which is primarily used for storing equipment. From Mrs. Martin’s
    direction of approach, she would have crossed the storage track before reaching the mainline track.
    The area along the tracks contained trees and other vegetation that obscured motorists’ view of the
    tracks to some degree. The trees and vegetation were located on Norfolk’s right-of-way.
    Mrs. Martin was very familiar with this particular crossing and consulted with other members
    of her family to develop an agreed procedure for crossing the tracks safely. According to the Martin
    family agreement, members of the family would stop in advance of the tracks, lower the windows
    of the vehicle slightly, turn the radio volume down or off, keep a lookout for a train, listen for a train,
    and refrain from crossing the tracks until it could be determined that no train was approaching.
    On the day in question, Mrs. Martin came to a complete stop before crossing either the
    storage track or the mainline track. As she was stopped, a train owned by Norfolk and operated by
    Norfolk’s engineer, Anthony Worley, approached from Mrs. Martin’s right at approximately thirty-
    three miles per hour. The train’s conductor, Danny Martin (“Conductor Martin”) saw the front
    bumper and hood of Mrs. Martin’s truck while she was stopped short of the storage track. He first
    became aware of the front of her vehicle when the train was approximately 400 feet from the
    crossing. Given the speed of the train, it would have taken approximately 8.3 seconds for the train
    to travel 400 feet. At some point during that period of time, Mrs. Martin began to move her vehicle
    forward. She crossed over the storage track onto the mainline track and was hit by the train.
    B.
    Teddy Martin,1 the surviving husband of Mrs. Martin, and Tennie Martin and Roya Mitchell,
    the adult children of Mrs. Martin, filed suit against Norfolk and Mr. Worley. In their complaint, the
    plaintiffs allege that Norfolk permitted vegetation at the crossing to block Mrs. Martin’s view of the
    approaching train and that Mr. Worley violated Tennessee Code Annotated section 65-12-108(2)
    (2004) by failing to sound the train’s whistle as the train approached the crossing. The plaintiffs
    allege that each of these failures was not only negligent but also reckless. Accordingly, the plaintiffs
    are seeking both compensatory and punitive damages.
    1
    Teddy Martin died on September 13, 2004, and the plaintiffs’ complaint was amended to list Tennie Martin
    and Roya Mitchell as plaintiffs individually and in their capacities as co-personal representatives of Mrs. Martin’s estate.

    1. The Defendants’ Motion for Summary Judgment
    The defendants, Norfolk and Mr. Worley, moved for summary judgment, arguing that there
    were no genuine issues of material fact and that Mrs. Martin was at least fifty percent at fault as a
    matter of law. The defendants’ motion includes several factual assertions.
    First, the defendants assert that Mrs. Martin had ample visibility from her initial stopped
    position and would have seen the train had she merely looked. To support this claim, the defendants
    submitted photographs that show the visibility from various locations at the crossing.
    Second, the defendants contend that Mrs. Martin’s vehicle moved from its initial position and
    stopped a second time near the storage track. The defendants refer to the testimony of Conductor
    Martin to support this assertion.
    Third, the defendants assert that from the position of her second stop, Mrs. Martin had a
    better opportunity to see the train and had more than enough time to safely maneuver her vehicle
    once the train became visible. In support of these assertions, the defendants offered the deposition
    testimony of their expert witness, Charles Manning. Mr. Manning testified that within fifteen to
    twenty feet of the mainline track a motorist would have 900 to 1000 feet of visibility. Mr. Manning
    further testified that under these circumstances nine to ten seconds would be sufficient for a person
    to see a train, react, and bring a vehicle to a stop in time to avoid a collision. Conductor Martin also
    testified that a motorist could see a substantial distance from the storage track.
    Finally, the defendants claim that Mr. Worley repeatedly blew the train’s whistle as the train
    approached the crossing and that Mrs. Martin had an opportunity to hear the train had she merely
    listened for it. In support of this assertion, the defendants offered the deposition testimony of Mr.
    Worley and the affidavits of two witnesses who stated that they heard a train whistle around the time
    of the collision. In light of these alleged facts, the defendants argue that no reasonable jury could
    conclude that Mrs. Martin acted reasonably or that she was any less than fifty percent at fault for the
    collision.
    2. The Plaintiffs’ Response to the Defendants’ Motion for Summary Judgment
    In the plaintiffs’ response to the motion for summary judgment, the plaintiffs set forth their
    own factual assertions. First, the plaintiffs assert that Mrs. Martin initially stopped her vehicle 12.93
    feet from the near rail of the storage track and 27 feet from the near rail of the mainline track. In
    support of this assertion, the plaintiffs submit the testimony and affidavit of their expert, Kenneth
    Heathington. Mr. Heathington based his calculation of Mrs. Martin’s stopping position on
    Conductor Martin’s testimony that he could see the front bumper and hood of Mrs. Martin’s truck
    when the train was approximately 400 feet from the crossing.
    Second, the plaintiffs assert that from this stopped position, vegetation would have limited
    Mrs. Martin’s ability to see more than 300 feet in the direction from which the train was
    approaching. This assertion is also based on the testimony and affidavit of Kenneth Heathington.
    -3-
    Third, the plaintiffs assert that when Mrs. Martin began to move forward from her stopped
    position she could not see the train because it was still over 300 feet away. This assertion is
    consistent with Conductor Martin’s testimony that the train was 400 feet away from the crossing
    when he first became aware of Mrs. Martin’s vehicle.
    Fourth, the plaintiffs assert that Mrs. Martin did not stop a second time but rather moved
    slowly and continuously across the crossing. In support of this assertion, the plaintiffs provide the
    deposition testimony of an eyewitness, Cecil Smith. According to Mr. Smith, Mrs. Martin’s vehicle
    was “creeping” across the railroad crossing prior to the collision. The plaintiffs also rely on
    Conductor Martin’s initial written statement in which he checked a box indicating that Mrs. Martin
    had “Stopped, then Proceeded” rather than checking a box designated “Other” and describing Mrs.
    Martin’s second stop.
    Fifth, the plaintiffs claim that once Mrs. Martin began to move forward from her initial
    stopped position she had insufficient time to perceive the train and bring her vehicle to a stop short
    of the mainline tracks. These allegations are also supported by the testimony and affidavit of
    Kenneth Heathington.
    Finally, the plaintiffs claim that Mr. Worley did not sound the train’s whistle as the train
    approached the crossing. In support of this assertion, the plaintiffs submit Mr. Smith’s testimony
    that he was in a position to hear a whistle but did not hear it. The plaintiffs argue that these factual
    assertions demonstrate the existence of genuine issues of material fact and therefore the defendants’
    motion for summary judgment should have been denied.
    3. The Rulings of the Trial Court and Court of Appeals
    In its ruling, the trial court emphasized that Mrs. Martin could see at least 300 feet from her
    stopped position and that she was familiar with the crossing. Specifically, the trial court stated, “Had
    she remained stopped, had she looked and listened, there’s no question in my mind, and in my
    opinion no question in any reasonable mind that she could have seen the train.” The trial court
    determined that no reasonable jury could conclude that Mrs. Martin was less than fifty percent at
    fault for the collision. Accordingly, the trial court granted the defendants’ motion for summary
    judgment.
    In a divided decision, the Court of Appeals affirmed the trial court’s grant of summary
    judgment. The majority concluded that the dispute concerning whether Mr. Worley sounded the
    train’s whistle was immaterial because the trial court’s judgment was based on the determination that
    Mrs. Martin failed to look for the train. Furthermore, the majority concluded that “the undisputed
    facts establish that the train was plainly visible and in hazardous proximity to the crossing when
    decedent proceeded to cross the railroad track” and that Mrs. Martin “could have easily seen the train
    had she looked.” In his dissenting opinion, Judge Susano argued that there were several genuine
    issues of material fact and that summary judgment was therefore inappropriate. We granted review
    to provide further guidance regarding the application of summary judgment in this State.

    II. Analysis
    A.
    As a preliminary matter, the defendants argue that they are entitled to summary judgment
    because Tennessee courts do not allow recovery for a claim asserting that an obstruction on a
    railroad’s right-of-way prevented a motorist from seeing a train. In other words, the defendants
    contend that railroad companies do not have a duty to ensure that railroad crossings provide a
    reasonable degree of visibility to motorists. This argument is based on a case decided by our Court
    of Appeals in 1928. See Tenn. Cent. Ry. Co. v. Hayes, 
    9 Tenn. App. 116
     (1928). In that case, the
    Court of Appeals stated, “Obstructions to vision are not an independent ground of recovery–certainly
    not, in this case when the defendant did not place them–but they must be considered upon the
    question of the proper degree of care and vigilance which the railroad company is bound to exercise
    in the running and management of its train and in giving warnings of its approach.” Id. at 122.
    This Court, however, has never approved of this holding. On the contrary, we have long
    recognized that railroads have a statutory and common-law duty to maintain adequate crossings for
    public highways. Tenn. Pub. Serv. Comm’n v. S. Ry. Co., 
    554 S.W.2d 612
    , 613 (Tenn. 1977); see
    also Tenn. Code Ann. § 65-11-101(a) (2004). It is clear that Norfolk’s operation of trains across
    public roadways necessarily involves a degree of risk to motorists, including Mrs. Martin. The
    creation of this risk necessarily entails the creation of a corresponding duty to take reasonable
    precautions to avoid injury to motorists. See Satterfield v. Breeding Insulation Co., No. E2006-
    00903-SC-R11-CV, 
    2008 WL 4135605
    , *4, ___ S.W.3d ___, ___ (Tenn. Sept. 9 2008). We
    therefore conclude that the duty to maintain an adequate crossing includes a duty to ensure that
    vegetation on the railroad’s right-of-way does not unreasonably interfere with motorists’ ability to
    perceive an oncoming train.2 To the extent Hayes is inconsistent with this holding, it is overruled.
    Accordingly, an injured party may recover for a claim based solely on a railroad’s breach of its duty
    to ensure that vegetation on its right-of-way does not unreasonably obstruct motorists’ view of
    approaching trains.
    B.
    We now turn to the central issue of whether the trial court correctly determined that no
    reasonable jury could conclude that Mrs. Martin was less than fifty percent at fault for the collision.
    The moving party is entitled to summary judgment only if the “pleadings, depositions, answers to
    2
    By recognizing this duty, it is not our intent to encroach upon federal authority to regulate the railroad
    industry. Federal regulations currently address the maintenance of vegetation “on or immediately adjacent to roadbed”
    and therefore preempt state efforts to regulate the maintenance of vegetation in that area. 49 C.F.R. § 213.37 (2007).
    Federal courts have recognized, however, that a railroad’s right-of-way often extends several yards from the roadbed and
    that federal regulations do not preempt state regulation of vegetation that is on the railroad’s right-of-way but not on or
    immediately adjacent to the roadbed. Mo. Pac. R.R. Co. v. R.R. Comm’n of Tex., 
    833 F.2d 570
    , 577 (5th Cir. 1987);
    see also Shanklin v. Norfolk S. Ry. Co., 
    369 F.3d 978
    , 987-88 (6th Cir. 2004). Accordingly, the duty we recognize today
    extends only to vegetation that is on the railroad’s right-of-way but not on or immediately adjacent to the roadbed.
    -5-
    interrogatories, and admissions on file, together with the affidavits . . . show that there is no genuine
    issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.”
    Tenn. R. Civ. P. 56.04; accord Penley v. Honda Motor Co., 
    31 S.W.3d 181
    , 183 (Tenn. 2000). The
    moving party has the ultimate burden of persuading the court that there are no genuine issues of
    material fact and that the moving party is entitled to judgment as a matter of law. Byrd v. Hall, 
    847 S.W.2d 208
    , 215 (Tenn. 1993). Accordingly, a properly supported motion for summary judgment
    must show that there are no genuine issues of material fact and that the moving party is entitled to
    judgment as a matter of law. See Staples v. CBL & Assocs., Inc., 
    15 S.W.3d 83
    , 88 (Tenn. 2000);
    McCarley v. W. Quality Food Serv., 
    960 S.W.2d 585
    , 588 (Tenn. 1998). If the moving party fails
    to make this showing, then “the non-movant’s burden to produce either supporting affidavits or
    discovery materials is not triggered and the motion for summary judgment fails.” McCarley, 960
    S.W.2d at 588; accord Staples, 15 S.W.3d at 88.
    The moving party may make the required showing and therefore shift the burden of
    production to the nonmoving party by either: (1) affirmatively negating an essential element of the
    nonmoving party’s claim; or (2) showing that the nonmoving party cannot prove an essential element
    of the claim at trial. Hannan v. Alltel Publ’g Co., ___ S.W.3d ___, ___ (Tenn. 2008); see also
    McCarley, 960 S.W.2d at 588; Byrd, 847 S.W.2d at 215 n.5. Both methods require something more
    than an assertion that the nonmoving party has no evidence. Byrd, 847 S.W.2d at 215. Similarly,
    the presentation of evidence that raises doubts about the nonmoving party’s ability to prove his or
    her claim is also insufficient. McCarley, 960 S.W.2d at 588. The moving party must either produce
    evidence or refer to evidence previously submitted by the nonmoving party that negates an essential
    element of the nonmoving party’s claim or shows that the nonmoving party cannot prove an essential
    element of the claim at trial. Hannan, ___ S.W.3d at ___. We have held that to negate an essential
    element of the claim, the moving party must point to evidence that tends to disprove an essential
    factual claim made by the nonmoving party. See Blair v. W. Town Mall, 
    130 S.W.3d 761
    , 768
    (Tenn. 2004). If the moving party is unable to make the required showing, then its motion for
    summary judgment will fail. Byrd, 847 S.W.2d at 215.
    If the moving party makes a properly supported motion, then the nonmoving party is required
    to produce evidence of specific facts establishing that genuine issues of material fact exist.
    McCarley, 960 S.W.2d at 588; Byrd, 847 S.W.2d at 215. The nonmoving party may satisfy its
    burden of production by:
    (1) pointing to evidence establishing material factual disputes that were over-looked
    or ignored by the moving party; (2) rehabilitating the evidence attacked by the
    moving party; (3) producing additional evidence establishing the existence of a
    genuine issue for trial; or (4) submitting an affidavit explaining the necessity for
    further discovery pursuant to Tenn. R. Civ. P., Rule 56.06.
    McCarley, 960 S.W.2d at 588; accord Byrd, 847 S.W.2d at 215 n.6. The nonmoving party’s
    evidence must be accepted as true, and any doubts concerning the existence of a genuine issue of
    material fact shall be resolved in favor of the nonmoving party. McCarley, 960 S.W.2d at 588. “A
    disputed fact is material if it must be decided in order to resolve the substantive claim or defense at
    -6-
    which the motion is directed.” Byrd, 847 S.W.2d at 215. A disputed fact presents a genuine issue
    if “a reasonable jury could legitimately resolve that fact in favor of one side or the other.” Id.
    Because the resolution of a motion for summary judgment is a matter of law, we review the
    trial court’s judgment de novo with no presumption of correctness. Blair, 130 S.W.3d at 763. In
    addition, we are required to review the evidence in the light most favorable to the nonmoving party
    and to draw all reasonable inferences favoring the nonmoving party. Staples, 15 S.W.3d at 89.
    C.
    In the present case, we conclude that the defendants’ motion was properly supported. On its
    face, the defendants’ motion negated the elements of breach of duty and causation by setting forth
    facts that tend to show that Norfolk and Mr. Worley acted reasonably and that Mrs. Martin did not
    exercise reasonable care. Specifically, the defendants submitted photographic evidence that
    suggested that some vantage points near the crossing provided substantial visibility down the tracks.
    Furthermore, the defendants presented evidence that Mrs. Martin made a second stop near the
    storage track and that she would have had substantial visibility from that location. The defendants
    also submitted expert testimony that Mrs. Martin would have had sufficient time to see the train,
    react, and bring her vehicle to a stop in a safe position. These alleged facts tend to show that Norfolk
    did not fail to provide adequate visibility at the crossing, that Mrs. Martin negligently failed to keep
    a proper lookout for a train, and that her negligence caused the collision. In addition, the defendants
    provided evidence that Mr. Worley did sound the train’s whistle as he approached the crossing, thus
    negating the plaintiffs’ claim that he breached his duty to blow the whistle. In light of these factual
    allegations, we have no difficulty concluding that the defendants’ motion affirmatively negated
    essential elements of the plaintiffs’ claim and therefore shifted the burden of production to the
    plaintiffs.
    The plaintiffs responded to the defendants’ motion by seeking to demonstrate that the
    defendants had ignored evidence in the record that established the existence of genuine issues of
    material fact. Specifically, the plaintiffs sought to demonstrate that there were genuine disputes
    regarding: (1) whether Mrs. Martin was able to see the train before leaving her initial stopped
    position; (2) whether Mrs. Martin stopped a second time; (3) whether Mrs. Martin had sufficient
    time to see the train, react, and bring her vehicle to a stop in a safe location; and (4) whether Mr.
    Worley sounded the train’s whistle. We will address each of these issues in turn.
    The plaintiffs presented expert testimony that Mrs. Martin stopped her vehicle 12.93 feet
    from the near rail of the storage track and 27 feet from the near rail of the mainline track. Mr.
    Heathington’s calculation of this distance was based upon Conductor Martin’s testimony that he
    could see the front bumper and hood of Mrs. Martin’s truck from approximately 400 feet away. Mr.
    Heathington also testified that from this position, Mrs. Martin would have been able to see only 300
    feet in the direction of the approaching train. Furthermore, the exact timing of Mrs. Martin’s
    decision to leave her stopped position is unclear from Conductor Martin’s testimony. Therefore, a
    reasonable jury could conclude that Mrs. Martin began to pull forward when the train was still more
    than 300 feet away and was not yet visible to her. Accordingly, we conclude that the plaintiffs’
    -7-
    evidence creates a genuine dispute concerning whether Mrs. Martin was able to see the train before
    leaving her initial stopped position.
    The plaintiffs also presented evidence challenging the defendants’ assertion that Mrs. Martin
    stopped a second time near the storage track. The plaintiffs provided the deposition testimony of an
    eyewitness, Mr. Smith, who stated that Mrs. Martin’s vehicle was “creeping” across the railroad
    crossing prior to the collision. Mr. Smith did not state that Mrs. Martin stopped a second time.
    Furthermore, the plaintiffs observe that Conductor Martin’s initial written statement did not mention
    a second stop. Although a space was provided in which Conductor Martin could have provided a
    more detailed description of the events leading up to the collision, he merely checked a box
    indicating that Mrs. Martin had “Stopped, then Proceeded.” A reasonable jury therefore could
    conclude that Mrs. Martin did not make a second stop. Accordingly, we conclude that there is a
    genuine dispute concerning whether Mrs. Martin made such a stop.
    The plaintiffs also submitted evidence to counter the defendants’ expert’s claim that Mrs.
    Martin had sufficient time to see the train, respond, and avoid the accident. Mr. Heathington, the
    plaintiffs’ expert, directly contradicted this claim. He stated that under the conditions present at the
    time of the accident, Mrs. Martin would not have had sufficient time to perceive the train and bring
    her vehicle to a stop short of the mainline tracks. The resolution of conflicting expert testimony is
    a factual issue that must be reserved for the trier of fact. See McDaniel v. CSX Transp., Inc., 
    955 S.W.2d 257
    , 265 (Tenn. 1997) (holding that “the weight to be given to stated scientific theories, and
    the resolution of legitimate but competing scientific views, are matters appropriately entrusted to the
    trier of fact”). It is undisputed that the train reached the crossing approximately 8.3 seconds after
    Conductor Martin first saw Mrs. Martin’s vehicle. Although it is unclear exactly when Mrs. Martin
    left her initial stopped position 27 feet from the mainline track, the facts demonstrate that she would
    have had 8.3 seconds or less to see the train and stop before the train arrived. While it is clear that
    Mrs. Martin’s visibility would have improved appreciably as she neared the track and as the train
    neared the crossing, the facts in the record do not provide any concrete answers as to when Mrs.
    Martin could have or should have seen the train. Accordingly, various inferences reasonably could
    be drawn. Viewing the facts in the light most favorable to the plaintiffs and affording the plaintiffs
    the benefit of all reasonable inferences, we believe a reasonable jury could accredit the plaintiffs’
    expert. Accordingly, we conclude that there is a genuine issue concerning whether Mrs. Martin had
    sufficient time to see the train, react, and bring her vehicle to a stop in a safe location.
    Finally, the plaintiffs presented evidence that Mr. Worley did not sound the train’s whistle.
    Mr. Smith testified that he was in a position to hear the train’s whistle but did not hear it.3 This
    3
    The defendants have moved this Court to supplement the record with deposition testimony that is purported
    to disclose that M r. Smith is hearing impaired. This deposition testimony, however, was not presented to the trial court.
    Accordingly, the record currently “convey[s] a fair, accurate and complete account of what transpired in the trial court,”
    and no supplementation is necessary. Tenn. R. App. P. 24(g). Although counsel for the defendants did argue before the
    trial court that M r. Smith is hearing impaired, it is a familiar maxim that argument of counsel is not evidence. See State
    v. Roberts, 755 S.W .2d 833, 836 (Tenn. Crim. App. 1988). Therefore, it would have been inappropriate for the trial
    (continued...)
    -8-
    testimony directly contradicts the evidence submitted by the defendants and clearly presents a
    genuine dispute over whether the whistle blew.
    Furthermore, each of these disputes concerns material facts. In Byrd, we held that a fact is
    material if “it must be decided in order to resolve the substantive claim or defense at which the
    motion is directed.” 847 S.W.2d at 215. Whether the train could be seen from Mrs. Martin’s initial
    stopped position is highly material because it has direct bearing on whether Mrs. Martin was
    negligent in her failure to see the train before pulling forward. Whether Mrs. Martin stopped a
    second time is also highly material because it is directly related to whether Mrs. Martin had stopped
    her vehicle in a position of safety from which she could clearly see the train approaching. If Mrs.
    Martin did stop her vehicle in such a position, it would be difficult to see how she could reasonably
    decide to resume proceeding over the tracks. If, on the other hand, Mrs. Martin was never stopped
    in such a position, the plaintiffs’ theory that Mrs. Martin simply did not have time to react to the
    approaching train is significantly more plausible. Similarly, whether Mrs. Martin had sufficient time
    to see the train, react, and bring her vehicle to a stop is central to the question of whether Mrs. Martin
    was negligent in her failure to yield to the train. Finally, whether Mr. Worley blew the train’s
    whistle is material to determining whether Mr. Worley and Norfolk breached their statutory duty to
    sound the train’s whistle prior to reaching the crossing. Tenn. Code Ann. § 65-12-108(2).
    Furthermore, whether the whistle blew is also relevant to determining whether Mrs. Martin could
    have reasonably avoided the collision. We therefore conclude that the plaintiffs have demonstrated
    the existence of several genuine issues of material fact and that the trial court erred in concluding
    that no reasonable jury could determine that Mrs. Martin was less than fifty percent at fault.
    We are puzzled that the trial court and the majority of the Court of Appeals failed to
    recognize the myriad of genuine and material factual disputes presented by this case. The plaintiffs
    have alleged that the defendants breached a duty owed to Mrs. Martin and that the alleged breach
    of duty was the actual and proximate cause of Mrs. Martin’s death. Furthermore, the plaintiffs have
    presented evidence supporting each element of their case, and this evidence must be viewed in the
    light most favorable to their case. Although a trial court may conclude that the plaintiffs’ case is not
    particularly strong, it is not the role of a trial or appellate court to weigh the evidence or substitute
    its judgment for that of the trier of fact. Byrd, 847 S.W.2d at 211. This case should serve as a
    reminder to lower courts that summary judgment is not appropriate in cases that present genuine
    disputes of material fact.
    D.
    The final issue for our determination relates to a pretrial evidentiary ruling of the trial court.
    Prior to the trial court’s grant of summary judgment, the defendants filed a motion in limine
    requesting the exclusion of evidence that Norfolk cleared the vegetation at the crossing thirty-one
    3
    (...continued)
    court to consider Mr. Smith’s purported hearing loss, and we decline to consider it for the first time on appeal. In any
    event, such evidence goes only to the weight of Mr. Smith’s testimony. Issues concerning the weight of testimony are
    normally reserved for the trier of fact. Miller v. W illbanks, 8 S.W .3d 607, 615 (Tenn. 1999).

    months after Mrs. Martin’s death. The defendants sought the exclusion of this evidence based on
    the rule governing subsequent remedial measures. See Tenn. R. Evid. 407 (2008). After hearing
    argument on the motion, the trial court excluded the evidence of the clearing from the compensatory
    damages stage of the trial but agreed to admit it in the event that a second punitive damages stage
    became necessary. The plaintiffs have appealed the trial court’s ruling.
    Tennessee Rule of Evidence 407 provides:
    When, after an event, measures are taken which, if taken previously, would have
    made the event less likely to occur, evidence of the subsequent remedial measures
    is not admissible to prove strict liability, negligence, or culpable conduct in
    connection with the event. This rule does not require the exclusion of evidence of
    subsequent measures when offered for another purpose, such as proving controverted
    ownership, control, or feasibility of precautionary measures, or impeachment.
    The purpose of this evidentiary rule is to “encourage remedial measures in order to serve the public’s
    interest in a safe environment.” Neil P. Cohen et al., Tennessee Law of Evidence § 4.07[2] (5th ed.
    2005). The word “subsequent” refers to events that occur after the events giving rise to the lawsuit.
    Rothstein v. Orange Grove Ctr., Inc., 
    60 S.W.3d 807
    , 813 (Tenn. 2001). An action is “remedial” if
    it “chang[es] a situation, usually an unsafe property or product, to prevent the situation from causing
    further injury.” Id. As with other evidentiary matters, we review a trial court’s decision to admit or
    exclude evidence under Tennessee Rule of Evidence 407 under an abuse of discretion standard. See
    State v. Lewis, 
    235 S.W.3d 136
    , 141 (Tenn. 2007). “An abuse of discretion occurs when the trial
    court applies an incorrect legal standard or reaches a conclusion that is ‘illogical or unreasonable and
    causes an injustice to the party complaining.’” Id. (quoting State v. Ruiz, 
    204 S.W.3d 772
    , 778
    (Tenn. 2006)).
    In response to the defendants’ motion, the plaintiffs have not offered a permissible ground
    for introducing the evidence. Rather, the plaintiffs argue that the clearing of the vegetation was
    neither subsequent nor remedial. While the plaintiffs acknowledge that the clearing of the vegetation
    followed the accident, they contend that the clearing was not subsequent because it was separated
    by too great a period of time. Furthermore, they argue that the clearing was not remedial because
    it was carried out in accordance with Norfolk’s internal policies rather than with the intent of
    remedying the condition that allegedly lead to Mrs. Martin’s death.
    We conclude that these arguments are without merit. The clearing is remedial because it
    corrected an allegedly dangerous condition and made the crossing safer for future motorists.
    Rothstein, 60 S.W.3d at 813. That the clearing was carried out pursuant to corporate policy does not
    undermine the remedial nature of the action. In addition, the clearing of the vegetation undisputedly
    followed the accident giving rise to this action. See id. That it occurred over two years later does
    not make the event any less subsequent. Accordingly, we conclude the trial court did not abuse its
    discretion in determining that Norfolk’s clearing of the vegetation is a subsequent remedial measure.
    -10-
    We recognize that other jurisdictions have held that subsequent remedial actions will not be
    excluded if the implementation of the remedy began before the accident but was not completed until
    after the accident. E.g., Schmeck v. City of Shawnee, 
    651 P.2d 585
    , 600 (Kan. 1982); Cupp v. Nat’l
    R.R. Passenger Corp., 
    138 S.W.3d 766
    , 776 (Mo. Ct. App. 2004). These cases, however, are
    factually distinguishable from the case before us. Although Norfolk had a policy of clearing
    vegetation from crossings prior to the collision, there is no evidence that Norfolk had made a
    decision to clear the vegetation at this particular crossing prior to the accident. Accordingly, these
    cases are inapposite, and we express no opinion regarding their adoption.
    Finally, the plaintiffs argue that the exclusion of subsequent remedial measures is
    unnecessary in this case because Norfolk’s clearing of the vegetation was required by Tennessee
    Code Annotated section 65-6-132(a) (2004). According to the plaintiffs’ argument, the application
    of Tennessee Rule of Evidence 407 is unnecessary to encourage railroads to take remedial measures
    because they are already statutorily obligated to provide visibility at crossings. Tennessee Code
    Annotated section 65-6-132(a) provides, “Every company or person operating a railroad in this state
    shall cut down all trees standing on its lands which are six (6) or more inches in a diameter two feet
    (2') above the ground and of sufficient height to reach the roadbed if they should fall.” The primary
    purpose of this statute is clearly to prevent large trees from falling across railroad tracks. Shanklin,
    369 F.3d at 992. Whether or not this statute is also intended to provide visibility to motorists, it is
    clear that compliance with the statute alone will not ensure that motorists have reasonable visibility
    at a crossing. After all, trees that are less than six inches in diameter or too short to reach the tracks
    may just as easily obscure a motorist’s view of a train. Accordingly, compliance with the statute
    alone is insufficient to encourage railroad companies to remedy dangerous crossings. We therefore
    conclude that the application of Tennessee Rule of Evidence 407 is necessary to encourage railroads
    to remedy visibility problems at crossings where accidents have occurred. The judgment of the trial
    court in this regard is affirmed.
    III. Conclusion
    We conclude that the plaintiffs have successfully demonstrated the existence of several
    genuine issues of material fact. Accordingly, we reverse the trial court’s judgment and remand for
    proceedings consistent with this opinion. Costs of this appeal are taxed to the appellees, Norfolk
    Southern Railway Co. and Anthony D. Worley, for which execution may issue if necessary.
