FACTUAL AND PROCEDURAL BACKGROUND
¶7 This action arises out of the tragic death of Raymond Naumer. Naumer’s mother, Darlene Payne, brings this suit on behalf of his estate. On October 25, 1998, Naumer’s friend, David Sail, purchased an antique Minneapolis Moline tractor from Jim and Dutch Knutson. Sail and Naumer collected the tractor at the Knutsons’ ranch near Geyser, Montana. Sail and Naumer’s plan was to load the tractor into the trailer attached to Sail’s truck, but, because the model was too wide, the two decided to drive both the truck and the tractor back to *167 Great Falls.
¶8 The Knutsons told Sail that the tractor was “field ready” and that nothing was wrong with it apart from the water pump. On a previous occasion, Sail inspected the tractor and took it for a test drive. At that time he determined that the gears were in working order, and he used the transmission to slow the tractor down. In his deposition he stated that he did use the brakes, but very briefly. The tractor had an unusual braking system, with right and left brake pedals for the respective wheels, and a master pedal that engages each wheel.
¶9 In their drive to Great Falls, Sail drove the tractor for some time, and during this time uneventfully negotiated some hills. After stopping for a break, he and Naumer agreed to switch vehicles. This was because Naumer lacked a driver’s license and so could not legally drive the truck. However, under Montana law, he could drive farm machinery, such as the tractor. Naumer then led the way and began driving the tractor up a hill of about a 7 percent grade. The hill was not as steep as some that Sail had driven over earlier. Naumer attempted to switch gears and Sail saw him drop a snuff can. The tractor then began rolling backwards. Naumer frantically tried to use the various brake pedals or put the machine into gear, but to no avail. Sail began running beside the tractor telling Naumer to either steer into the hill or jump out. After approximately nine seconds, Sail could no longer keep up with the machine. With the vehicle careening out of control, Naumer finally jumped out. At this moment the tractor swerved and crushed him.
¶10 Darlene Payne subsequently brought this negligence action against the Knutsons. At trial, Payne argued that the Knutsons either did not sufficiently inspect the tractor’s brakes, or did not tell Sail and Naumer that the brakes were deficient. The parties made a joint inspection of the tractor’s remains and discovered that the right brake pad was almost completely worn down. Importantly, they also found that the dust cover for the right brake was blackened. In his deposition, Sail stated that the dust cover was not blackened when they switched vehicles. The Knutsons argue that this may have been because Naumer drove with the right brake engaged. This may have overheated the brake, causing the blackening of the dust cover and a quick deterioration of the right brake pad. With this deterioration Naumer would have been unable to stop the tractor by engaging the right brake pedal or even the master pedal. The left pedal may have been sufficient, but expert testimony stated that he would have had to engage it for a couple seconds, perhaps longer than he did in his *168 panicked state.
¶ 11 In their testimony, both of the Knutsons gave certain introductory remarks concerning their life histories and hobbies. Dutch Knuston also testified regarding his disabled hips. Payne objected to this testimony on the grounds that it was irrelevant and was designed to elicit sympathy for the Knutsons.
¶12 The court instructed the jury to complete a special verdict form. The form separately asked if Jim Knutson, Dutch Knutson, and Naumer were negligent and were a cause of Naumer’s death. Then, it asked the jury to apportion percentages of negligence among the three. At first the jury was deadlocked over whether the Knutsons were negligent at all. After further deliberation, the jury told the court that eight jurors (the threshold number) agreed that the Knutsons were negligent, four did not, and of the eight, six agreed that Naumer was more than 51 percent at fault. Through their instructions, the jury knew that the Knutsons would not be liable if Naumer was more than 51 percent at fault, so the jury asked if it needed to go forward and apportion the negligence percentages for each of the Knutsons. The court answered “no” and the jury subsequently rendered its verdict, finding Naumer more than 51 percent at fault. Before the verdict, Payne objected to the court’s “no” answer, requested a new trial and argued that the law requires the jury to apportion negligence to all parties. After the jury delivered its verdict, Payne moved for a new trial and to amend the judgment. Payne now appeals, asking this Court to conclude that Naumer was not negligent as a matter of law, reverse the District Court’s refusal to amend the judgment, and remand for a new trial on the issue of damages. In the alternative, Payne asks us to grant her a new trial on all issues. We first address her arguments regarding her request for a new trial.
DISCUSSION
ISSUE ONE
¶13 Whether the District Court erred when it instructed the jury that it need not apportion percentages of negligence to the Knutsons.
¶14 We give great leeway to the district courts in instructing the jury, and therefore will only overturn a jury instruction in the case of an abuse of discretion.
Dale v. Three Rivers Tels. Coops.,
Inc.,
¶15 Payne appeals from a denial of her motion for a new trial. Her appeal is predicated on the argument that the court’s advising the jury that it did not have to apportion negligence to the Knutsons was an incorrect conclusion of law because § 27-1-703(4), MCA, states that in a case such as this “[t]he trier of fact shall apportion the percentage of negligence of all persons listed in this subsection.” (Emphasis added.) The only relevant “persons” here are Naumer and the Knutsons.
¶16 Payne contends that a special verdict form, such as that used here, is. designed to force the jury to avoid generalities and pay close attention to the relative fault of the parties. In arguing this, Payne misses the larger rationale behind special verdict forms. In our system of comparative negligence, special verdict forms exist so that the jury can apportion percentages of negligence to the parties. Without apportionment, whether it helps jurors “focus their minds” or not, comparing negligence is impossible. In this case, the purpose of apportionment-determining the degree of fault-was fulfilled when the jury determined that Naumer’s negligence exceeded 50 percent and thus he was precluded from recovering against the defendants whose negligence would, of necessity, be less than 50 percent.
¶17 More so, however, whether or not the District Court’s conclusions of law regarding § 27-1-703(4), MCA, were correct, Payne’s argument has no force if she was not prejudiced. This Court has recognized that in appeals concerning the trial court’s instructions to the jury, the appellant must establish prejudice from the erroneous instruction.
Geiger v. Sherrodd, Inc.
(1993),
¶18 Under § 27-1-702, MCA, a plaintiff cannot recover if his *170 contributory negligence exceeds the combined negligence of the defendants. Here, using the special verdict form, ten of the twelve jurors agreed to attribute “greater than 51 percent” negligence to Naumer. At this point, six of those ten jurors would have had to change their minds and ascribe “50 percent or less” negligence to Naumer if the Knutsons were to be at all liable. Whatever negligence these jurors might have apportioned to the Knutsons, it is highly speculative to conclude that the act of apportioning the remaining 49 percent would so exercise their faculties that six of the ten jurors would change their minds as to Naumer’s percentage of negligence. Because speculation is all that Payne can offer regarding prejudice, we conclude that the District Court was within its discretion in instructing the jury not to proceed with apportioning the defendants’ percentages of negligence.
ISSUE TWO
¶19 Whether the District Court improperly admitted evidence that painted the Knutsons in a sympathetic light.
¶20 When reviewing a district court’s evidentiary ruling our standard of review is whether the court abused its discretion.
Kiely Constr. L.L.C. v. City of Red Lodge,
¶21 Each of the Knutsons opened their testimony with personal information regarding their family backgrounds and hobbies. Dutch Knutson said he volunteers with the local Johnny Mack band and high school band. Jim Knutson stated that he is a member of the local fire department. Dutch Knutson also testified regarding his disabled hips and the fact that he walks with a limp. Payne argues that this testimony was irrelevant, and seems to argue, in the alternative, that it was overly prejudicial.
¶22 Evidence is relevant if it has “any tendency to make the existence *171 of any fact that is of consequence -to the determination of the action more probable or less probable than it would be without the evidence.” Rule 401, M.R.Evid. As the Knutsons suggest, it was relevant that Jim Knutson volunteers with his fire department. That he was an experienced fireman made it more likely that he was familiar with safety concerns, such as making sure the tractor’s brakes worked. Also as the Knutsons suggest, Dutch Knutson’s bad hips were relevant. That he was able to use the tractor’s brakes even though he had bad hips made it more likely that the young and healthy Naumer could use them if he was not negligent. Although Dutch Knutson’s volunteer work with young musicians was not relevant, his remarks on this aspect of his life were brief and introductory and the court was within its discretion to allow them.
¶23 Even though relevant, under Rule 403, M.R.Evid., evidence may be excluded if its probative value is “substantially outweighed” by unfair prejudice. None of the above testimony rises to this level. The District Court did not abuse its discretion.
ISSUE THREE
¶24 Whether there was insufficient evidence to support the jury’s verdict.
¶25 When reviewing the district court’s refusal to grant a new trial based upon insufficiency of the evidence, our standard of review is to ask if the verdict was supported by substantial credible evidence.
Jenks v. Bertelsen,
¶26 There is substantial credible evidence that supports the jury’s finding that Naumer was more negligent than the Knutsons. There is credible evidence that Naumer left the right brake on while driving the tractor and that this directly led to his inability to stop the tractor. The evidence includes Sail’s statement that the right dust cover was not blackened before he and Naumer switched vehicles, expert testimony regarding the deterioration of brakes, and the near-total wearing of the right brake pad. Furthermore, there is the evidence that Sail drove *172 the tractor without incident before Naumer began driving. This left the jury with substantial credible evidence that Naumer was negligent in operating the tractor, and that he was responsible for over 51 percent of fault.
ISSUE FOUR
¶27 Whether Payne preserved the issue of “sudden emergency” for appeal.
¶28 As we stated earlier, Payne’s primary request in this case is that we reverse the District Court’s refusal to amend its judgment.
See
Rule 59(g), M.R.Civ.P. She contends that under the sudden emergency doctrine,
see Simonson v. White
(1986),
¶29 The District Court’s denial of Payne’s motions to amend the judgment and for a new trial is affirmed.
