Appeal from a judgment granting a new trial as to damages, unless both sides agreed to an addition of $3,000 to a general damage jury award of $2,000 and special damages of $2,500.1 Defendants withheld consent.
Two questions require consideration: 1) Was the court’s refusal to instruct on “unavoidable accident” prejudicial error? 2) Did the court abuse its discretion in granting a new trial? We consider these questions in the order stated.
1) The failure to instruct on “unavoidable accident” was not prejudicial error.
In the rolling knoll country of Nebraska, a truck towing a house trailer at about 45-50 m. p. h. followed by a Studebaker, followed by a Cadillac, in which plaintiff was riding, followed by defendant Adams’ truck-trailer, ran out of gas and was driven alongside the highway and stopped. The Studebaker passed. The Cadillac pulled up and stopped, signalling traffic behind. The vehicle driven by defendant Adams, having followed this combination of vehicles for. some five miles, came over the crest of the swells and rammed the Cadillac, pushing it forward some 15-20 feet, in which collision plaintiff suffered a whiplash. The driver says he did not see the parked cars until about 100 feet away, and was unable to stop to avoid the collision. Technical expert opinion justifies such conclusion assuming such circumstances. However, other evidence indicates that Adams should have seen the stopped vehicle when he was much farther away.
*352We have stated sparingly here only such circumstances, controverted or otherwise, as would justify an instruction on an unavoidable accident, depending of course on the facts of each individual case. The court in its instructions fully instructed the jury on the question of negligence and proximate cause.
This court has held that in cases where the facts warrant doing so, it is -not error to give an instruction on unavoidable accidents.2 However, actually such an instruction in most cases is superfluous in view of the other instructions which are given covering the basic issues in accident cases and serves no useful purpose except to add to the length of the instructions and to that extent detract from their effectiveness. We know of no case where this court has ever held the failure to give an instruction on unavoidable accident to be prejudicial error. As stated in Porter v. Price, “In most cases the usual instructions ■on negligence and proximate cause makes it sufficiently clear that the plaintiff must sustain his burden of proof on these issues in order to recover, * * 3
When the error assigned is the giving or failure to give instructions, the real inquiry should be were the issues of fact necessary to be determined, and the principles of law applicable thereto, correctly presented to the jury in a clear and understandable manner? That is the purpose of instruction and if it is accomplished, the failure to give additional ones is not of controlling importance. In this case the court told the jury in clear and unmistakable language that there could be no recovery unless plaintiff proved by a preponderance of the evidence that the defendant was negligent and such negligence proximately caused the accident, which terms were properly defined and related to the specific acts of negligence charged. The only possible meaning and effect of this instruction was to advise the jury that they could not find for the plaintiff, if the occurrence was an unavoidable accident. This is an adequate answer to the plaintiff’s complaint about the failure to instruct on the subject of unavoidable accident. But the court went further and although it did not use the exact words of the defendant’s request, gave another instruction which covered it in substance. In its instruction No. 13, the court stated: “The mere fact that a collision happened, considered alone, does not support an inference that any party to this action was negligent.”
Here the issue of unavoidable accident is not involved any more than in practically any other accident case. The defendant’s driver said that he saw the cars travelling *353ahead of him; that as he came over the crest of the hill there were no indications that they were stopped; then he “glanced on up the hill [ahead] and back at them, and about that time I realized they were stopped.” He was then within about 100 feet of plaintiff’s car and too close to stop before striking it. He, of course, was aware of the danger of his heavy load and the difficulties involved in bringing it to a stop and the consequent necessity of keeping a safe distance and a close watch on the cars ahead. Thus, there was ample basis to find him negligent, and only the ordinary indication of an unavoidable accident.
In view of the court’s full instructions that unless satisfied by a preponderance of the evidence that defendant’s negligence proximately caused plaintiff’s injuries, she could not recover, if the accident were unavoidable, that is, not caused by negligence, plaintiff could not recover under the instructions given for such instructions not only require proof of negligence but proof of negligence by the defendant which proximately caused plaintiff’s injury. So we find no error in failing to so instruct.
2) The court did not abuse its discretion in granting a new trial.
The trial court has a broad discretion in ruling on such a motion which we should not disturb unless there is a plain abuse thereof. We apply a different rule in determining whether this court on appeal should grant a new trial and whether the trial court abused its discretion in granting a new trial. The appellate court should overrule the trial court’s denial of a new trial involving a jury verdict only when upon a survey of all the evidence and the reasonable inferences to be drawn therefrom and when viewed in the light most favorable to the jury verdict, the amount of the award cannot be justified from the evidence on any reasonable basis. Of course, if the trial court’s order granting a new trial is expressly made on a misconception of the law, we should correct such misconception by reversing such an order granting a new trial.4 For the trial court has no discretion to grant a new trial in order to misapply the law.
Where, as here, a new trial was granted because the trial court found the jury had clearly been mistaken or misconceived the facts or the law on the amount of the damage, or that the verdict was the result of passion and prejudice, we should affirm his decision in granting a new trial unless he has clearly abused his discretion.5 The mere fact that the jury *354verdict is supported by substantial evidence sufficient to make, a prima facie case and furnish a reasonable basis for their decision does not require that the trial court’s order granting a new trial should be reversed. This is especially true where the order for the new trial is based on the amount of the verdict.6 The trial judge should not grant a new trial, merely because in his opinion the amount of the award was insufficient or excessive.7 Such action is warranted only when to the trial judge, “it seems clear that the jury has misapplied or failed to take into account proven facts; or misunderstood or disregarded the law; or made findings clearly against the weight of the evidence * * 8
Such test depends largely on the reaction and judgment of the trial judge. The members of this court and other persons might react to the same situation differently. This makes it very difficult for a reviewing court to determine whether there has been an abuse of trial court’s discretion. However, since the trial judge has seen and heard the witnesses and had a first-hand view of all of the evidence, and the proceedings throughout the trial and has ruled on the admissibility of the evidence, and instructed the jury on the law governing their verdict, and had opportunity of observing the tactics of the counsel throughout the trial and the jury’s reaction thereto, his ruling on a motion for a new trial should not be overruled unless it clearly appears that he has abused his discretion.9 This court has held in determining whether there has been an abuse of discretion, that where there is substantial evidence showing a reasonable basis to support a verdict in favor of the party moving for a new trial, there is no abuse of discretion in granting a new trial.10- In some cases, such rule should not be controlling.
Applying the foregoing rules to the evidence we find no abuse of discretion. From the evidence the trial judge could reasonably conclude that the jury had misapplied or failed to take into account prov*355en facts, or misunderstood or disregarded the law or made findings clearly against the weight of the evidence. This is sufficient to justify the granting of a new trial for a resubmission of that issue to another jury. So there was clearly no abuse of discretion. Although the order granting a new trial on damages only is permitted by our Rules of Civil Procedure,11 we think that justice and fairness in this case require a new trial on all the issues and not merely on the amount of damages. It is so ordered. No costs awarded.
