These cases arise out of a multicar accident which occurred on April 28, 1971, on the eastbound portion of Route 25 in Wareham, Massachusetts. The cases were tried to a jury in the Superior Court. At the close of the plaintiffs’ evidence with respect to liability, the trial judge granted motions for directed verdicts as to all defendants in all cases. The plaintiff Mary V. Alholm, a passenger in one of the vehicles involved in the accident, brought actions for personal injuries against the town of *623 Wareham, against the drivers of the other vehicles involved in the accident, and against H. P. Hood, Inc., as the employer of one of the drivers. 2 She appealed from the judge’s rulings on the motions for directed verdicts as to all defendants.
The plaintiffs Sylvia and Jackson, who are also defendants in the Alholm action, and Albert Guidaboni, the owner of a vehicle involved in the accident, bring these appeals only with respect to the question of the liability of the defendant town. The plaintiffs alleged that the town had maintained a public nuisance in the form of a town dump on property adjoining the public highway, the smoke from which severely impaired the visibility of travelers on the highway. They further alleged that the town had been negligent in its maintenance and operation of the dump and that its negligence had resulted in the impaired visibility on the highway which caused the accident. With respect to the drivers of the other vehicles involved, the plaintiff Alholm alleged that each driver had been negligent in the operation of his vehicle in light of the prevailing conditions of visibility. The trial judge granted the town’s motion for directed verdicts on the specific ground that the doctrine of municipal immunity barred recovery. The motions of the defendant operators were granted on the ground that the evidence was insufficient to support a jury finding that the plaintiffs’ injuries were caused in whole or in part by the negligence of any of the individual operators. We conclude that there was no error in the allowance of the motions for directed verdicts, except as to the actions of the plaintiff Alholm against the defendants Johnson and Perrone.
1. We must view the evidence in the light most favorable to the plaintiffs.
Chase
v.
Roy,
The collision occurred on April 28,1971, about 7:30 a.m. on the eastbound portion of Route 25 in Wareham, which in that vicinity consists of a breakdown lane, two driving lanes, and a passing lane bounded by an unenclosed median strip which is almost flush with the roadway. At a distance of about 450 feet south of the accident site is located a tract of land owned by the town of Wareham upon which it operated a dump for the use of town residents.
Surface and subterranean burning had occurred at the dump periodically for ten years prior to the accident. The dump had been smoldering since March 26,1971, on which date Robert Donovan, Director of the Southeastern Massachusetts Air Pollution Control District, an agency of the Massachusetts Department of Public Health, observed open burning at the dump, as a result of which he sent the town a notice of the violation. About a week prior to the accident, smoke was seen blowing across the highway from the dump. The dump was smoldering on April 27 and 28, and open burning of refuse in the dump was observed on the morning of the accident at 10:35 a.m. The fire was extinguished during the week following the accident by a process which involved excavation and the pouring of 1.25 million gallons of water on the area.
The collision occurred in a bank of fog and smoke in which visibility was reduced virtually to zero. A State police officer who arrived at the scene about 7:45 a.m. described visibility conditions as “like a smog, like a gray wall” and indicated that in addition to fog there was a “heavy odor of smoke irritating to the eyes.” Several operators testified that they could smell smoke after the accident and that the smoke caused tearing of eyes and coughing.
However, there was also testimony that the area in and *625 around Wareham was covered by an extremely heavy fog about 7 a.m. on the morning of the accident. There was no breeze. Visibility one-half mile from the scene of the accident in two directions was as poor as it was at the scene of the accident shortly before and after the accident. Virtually every witness who testified as to the visibility conditions at the scene of the accident emphasized the presence of a heavy stationary fogbank. While several witnesses testified to smelling smoke at the scene, only one driver thought that he could visually distinguish smoke present in the fogbank. In addition, there was repeated testimony that visibility had improved markedly by approximately 9 a.m. after the fog lifted. There was also testimony that the terrain surrounding the accident scene was a boggy, marshy area in which fog was a relatively frequent occurrence.
We conclude that, while there was evidence from which the jury could find that the town was maintaining a public nuisance and that the town was negligent in its maintenance of the dump, there was no evidence on which a jury could rationally base a conclusion that the smoke from the dump was causally related to the accident. Therefore, we need not here consider the issues of whether the governmental immmunity doctrine precludes recovery against a municipality for personal injuries caused by a public nuisance maintained by the municipality or whether the dump was a commercial enterprise for negligence in the operation of which the town may be liable. The trial judge was correct in directing a verdict for the defendant town. The judge did not base his determination on the ground on which we proceed, but the granting of such a motion will be upheld if there is any valid ground on which the motion should have been granted.

v.
Reiter Oldsmobile, Inc.,
The plaintiffs had the burden of proving that the alleged nuisance or negligence was the proximate cause of their injuries. It was incumbent on the plaintiffs to demonstrate a greater likelihood that their injuries were caused by a nuisance maintained by the defendant town or by its negligence than by some other cause for which it was not liable.
Nass
v.
Duxbury,
The nature of the burden thus placed on the plaintiffs was most comprehensively set forth in
Bigwood
v.
Boston & N. St. Ry.,
The evidence in these cases regarding the presence of an extremely heavy fog was overwhelming. There was no evidence regarding the amount of smoke which was emanating from the dump at the time of the accident or the amount of smoke which may have reached the highway 450 feet away.
A motion for a directed verdict can properly be granted “only where, construing the evidence most favorably to the plaintiff, it is still insufficient to support a verdict in his favor.”
DiMarzo
v.
S. & P. Realty Corp.,
We conclude that there was no evidence on which a jury could base a rational inference that the dump smoke was “an operative and potent factor” in causing the accident. See

Ludwig,
2. We now examine the evidence regarding the negligence of the defendant operators, construed in the light most favorable to the plaintiff Alholm, who was the only person to pursue this appeal against the operators involved in the collision. As to each of the defendants there was evidence to warrant an inference of negligence in the speed and manner in which they operated their vehicles under the conditions of poor visibility. See
Chase
v.
Roy,
In reaching this conclusion we are guided by the general principles of causation set out,
infra,
as to the action against the town of Wareham, and more particularly guided by analysis which we have applied as to causation in similar cases of multivehicle accidents. See
Chase
v.
Roy,
The state of proof as to the operators Johnson and Perrone was substantially different because of reasonable inferences which could be drawn from the testimony, when considered together, of the witnesses Alholm, Collette, Johnson and Perrone.
Albert F. Collette, Jr., the brother of the plaintiff Alholm, was operating a pale blue 1964 Buick automobile. His sister was in the front seat beside him. He entered the area of poor visibility at a speed of thirty to thirty-five miles an hour in the passing lane. His visibility decreased as he proceeded. He braked down to a speed of fifteen to twenty miles an hour but did not slow down further or stop because he was afraid of being struck in the rear. While proceeding at this decreased speed, he saw the lights of a car in front of him in the same lane about fifteen feet ahead of him. He applied his brakes but was unable to avoid colliding with the vehicle ahead of him. Neither he nor his sister was injured by this impact. Several seconds later the Collette vehicle was struck from the rear. Collette was thrown into the passenger side of the front seat, and his sister Mary Alholm was thrown out of the vehicle by the force of this impact. Collette left the car by the passenger side, found his sister on the pavement, and carried her to a place of safety.
The defendant Johnson was operating a 1968 Chevrolet Malibu automobile in the center lane at a speed of forty-five to fifty miles an hour when he entered the area of low visibility. His visibility had decreased to about a car *630 length when he saw vehicles blocking the road ahead of him, one of which was a Ford truck and the other of which was a Buick. He struck both vehicles, first hitting the truck and then the Buick. He was unable to estimate his speed at impact. With the use of a photographic exhibit, he identified the Buick which he had struck as the Collette vehicle.
The defendant David A. Perrone was operating a 1971 Ford Maverick automobile in the center lane at a speed of approximately sixty miles an hour. He entered the fog-bank at a speed of approximately fifty miles an hour. After proceeding into this area for about 100 feet, he removed his foot from the accelerator and was about to apply his brakes when he collided with a vehicle which was perpendicular to his lane. His speed at impact was forty to forty-five miles an hour. He heard no noises and felt no further impacts after colliding with this vehicle. Four or five days after the accident, Perrone visited Alholm in the hospital. During the course of their conversation, he inquired as to the type of vehicle in which she had been riding. In response to her reply that the car was a powder blue Buick, Perrone stated that the last thing he remembered prior to impact was seeing a blue Buick ahead of him.
In sum, with the exception of the defendant Johnson, who testified to having struck the car in which the plaintiff was a passenger, and the defendant Perrone, who communicated to the plaintiff Alholm that the last thing he remembered prior to impact was seeing a blue Buick, there was insufficient evidence of a causal relationship between the negligence of any individual driver and the injuries suffered by Alholm.
The defendant Johnson stresses that he testified that the Collette vehicle was empty when he collided with it and that he searched the area around the vehicle and found no one there. The jury are not required to believe this testimony, and the fact that the jury could find that the Johnson-Collette impact was not the one which caused Alholm’s injuries does not mean that they could not find otherwise. The evidence presents issues susceptible of rea *631 soned consideration and resolution by the jury, including a permissible determination of the issue as to which of the two defendants, Johnson or Perrone, was legally responsible to Alholm. The jury, of course, might also permissibly conclude that neither defendant was responsible.
We do not imply that evidence of causal relationship need in every case be as direct as the evidence here relating to Johnson and Perrone. Sufficient evidence could certainly arise inferentially in many different ways. Nevertheless, except for the cases against Johnson and Perrone, the confusion surrounding the sequence of events which transpired prior to Alholm’s injuries is too attenuated a basis for jury consideration of the causal relationship.
3. There was no error in the trial judge’s exclusion of evidence. Alholm offered to prove the position of all the cars after the fog had lifted through the testimony of Chester W. Campbell, a State police corporal who arrived at the scene of the accident shortly after it occurred to aid another State trooper in closing the road. The fog lifted approximately one hour after Corporal Campbell arrived at the scene, and at that time he conducted an investigation of the accident which included the preparation of a diagram. The trial judge excluded both the diagram made after the fog lifted and testimony by Corporal Campbell as to his observations of the relative positions of the vehicles at that time. The witness was unable to state whether any of the vehicles had been moved during the interval between the accident and the making of the diagram. There was other testimony that the relative positions of the vehicles had shifted substantially from the time of initial impact to the time when the fog lifted. The judge concluded that the positions of the vehicles after the fog lifted was too remote from the actual positions of vehicles at the time of impact to be of aid to the jury in reconstructing the series of events which occurred. Such a determination is within the sound discretion of the trial judge.
Charles L. Hazelton & Son
v.
Teel,
4. The directed verdicts for the town of Wareham and the defendants H. P. Hood, Inc., Oliver, Gray, Tanous, Reed, Sylvia, Olson, Barrs, and Jackson must be upheld. The directed verdicts for the defendants Johnson and Perrone must be reversed and the actions against them by the plaintiff Alholm remanded for new trial.
So ordered.
Notes
The plaintiff Alholm thus brought actions against the town, and against the defendants H. P. Hood, Inc., Lawrence Oliver, Alfred W. Johnson, Henry D. Gray, Jr., Frederick Tanous, Robert D. Reed, John F. Sylvia, Jr., Everett R. Olson, Andrew Barrs, David L. Jackson, and David A. Perrone.
This court has never been squarely confronted with the question whether municipalities may be held liable for injuries resulting from a public nuisance. It is well settled that a municipality is liable for injury resulting from its maintenance of a private nuisance.
