Opinion by
The Commonwealth sued to recover for damages done one of its highways (U. S. Route 15 in Lycoming County) by the burning thereon of a tractor-trailer and its cargo of gasoline. The tractor-trailer was the property of the defendant company and, at the time the fire occurred, was being operated by an employe of the defendant on the latter’s business. The conflagration completely destroyed the automotive equipment.
In its complaint, the plaintiff averred the happening and character of the accident; that, at all times material to the action, the maintenance and operation of the tractor-trailer was in the exclusive control of the defendant, its agents or servants; and that the fire was caused solely by the negligence and carelessness of the defendant, its agents or servants. The complaint did not, however, contain any averment of a specific act of negligence. The defendant filed preliminary objections asserting that the complaint failed to state a cause of action. The court en banc sustained the preliminary objections with leave to the plaintiff to amend. The plaintiff avowedly being unable in the circumstances to assign the cause of the fire, no amendment was offered and judgment was thereafter entered for the defendant on the pleadings. This appeal by the plaintiff followed.
It is, of course, hornbook that negligence is not to be presumed from the mere happening of an accident: Conway v. Philadelphia Gas Works Company,
We recently applied the doctrine of exclusive control in Turek v. Pennsylvania Railroad Company,
Here, defendant’s preliminary objections admit its exclusive control of the maintenance and operation of the tractor-trailer at the time involved. The inquiry remaining, therefore, is whether the accident was such as in the ordinary course of things does not happen if proper care is exercised. It is on that essentially factual question that the greatest difference appears in the decisions with respect to the applicability of the doctrine of exclusive control. Necessarily, there can be no arbitrary standard for determining the unusualness of an accident. But, the decided cases in this State limn a helpful pattern. Thus, the drifting of an unoccupied automobile downhill was held to have been unusual and not likely to have occurred if due care had been taken by the operator before leaving it: Hickerson v. Daskam,
The question, then, of importance here is whether gasoline trucks catch fire on the public highways in the ordinary course of things if they are properly maintained, loaded and operated. We think the answer to that question must be in the negative. Certainly, the defendant cannot well argue what, in final analysis, must mean that, in the usual operation of its trucking business, it was likely to cause dangerous conflagrations on public highways even though it exercised .proper care in the maintenance and operation of its automotive vehicles. The facts pleaded by the plaintiff, when proven, will afford an inference of negligence that will carry the case to the jury; and the duty will then be upon the defendant to exculpate itself by acceptable explanation that the accident occurred through no fault of its own.
Judgment reversed with a procedendo.
