Prentice, C. J.

The plaintiff, at the time he was injured, had completed his day’s work for the defendant, put away his tools and started to go home. In the pursuit of .this latter purpose he was engaged in no service for which he was employed, nor any incident of it, and in no attempt to advance the latter’s interests. He was intent solely upon an affair of his own, to wit, *290 reaching his home. His employer was under no obligation, contractual or otherwise, to furnish him transportation, as was the case in Swanson v. Latham, 92 Conn. 87, 101 Atl. 492. It, therefore, had no atom of authority over the method resorted to by him to reach his destination. He was bent upon his own errand, and was not otherwise connected with his employer or his employment than is every workman who walks, rides with a friend, or patronizes a trolley or steam car line to traverse the distance which separates his work from his home.

The truck upon which he was attempting to secure a lift on his homeward journey at the time he was injured by a fall therefrom, neither belonged to the employer nor was under its control at the time. It was not then an instrumentality employed in the conduct of its business. It had, it is true, been such instrumentality during the working hours of the day; but those hours had passed, and with their passage its service as an instrumentality of the defendant had for the time being been terminated, and, like the plaintiff, it had started on its homeward journey. Like him, 'it was at the time of the accident engaged in no attempt to advance the interests of the defendant, but was engaged upon a matter purely of its own concern. The defendant had no control or right of direction over its movements whatsoever. Whether it went directly to its destination unloaded, or sought a load on its way, welcomed persons to a free ride, or took passengers for pay, was a matter of no concern to the defendant, and it was in no position to interpose objections or directions in those regards. As it could not rightfully object, its failure to volunteer objections could not be imputed to it as accomplishing, through acquiescence in it, an assumption of responsibility for what the truck or its driver did, as the commissioner appears to have done.

*291 We are unable to discover a single fact upon which the commissioner’s conclusion could properly be based, that the plaintiff’s injuries arose out of and in the course of his employment. As well might it be said that an injury received by the plaintiff on his way home, had he, according to his known custom, been riding or attempting to ride in a trolley-car or, for that matter, walking, had that been his known custom, was one arising out of and in the course of his employment. In no essential particular would the situations thus presented differ from that presented here.

To be sure, the finding states that the plaintiff was an ignorant man speaking and understanding English very indifferently, that he had no knowledge either that the truck upon which he attempted to ride did not belong to the defendant, or of the nature of the contract of hiring under which it was used, and that he supposed and believed, as he naturally might, that he could ride thereon from his place of work to or toward his home. He knew, at least, that his employer had assumed no responsibility for his transportation, and neither his ignorance nor his unfounded belief in the matter covered by the commissioner’s finding, to which the defendant did not contribute by misrepresentation or other form of deception, can add anything to the latter’s responsibility upon the facts as they actually were.

The commissioner, in his memorandum of decision, places reliance for his conclusion that the plaintiff is entitled to compensation for his injury as one arising out of and in the course of his employment, upon the decisions of this court in Fiarenzo v. Richards & Co., 93 Conn. 581, 107 Atl. 563, and Marchiatello v. Lynch Realty Co., 94 Conn. 260, 108 Atl. 799; and the court below cites the latter case as announcing principles justifying the conclusion at which the commissioner arrived. We fail to discover anything more than the *292 most superficial similarity between the circumstances presented by those cases and the conditions here shown, and no principle enunciated in either which furnishes any warrant for holding that the present plaintiff’s injury arose out of and in the course of his employment.

In the Fiarenzo case the injured man and the truck from which he fell were both engaged in the performance of the master’s business, and at the moment of accident both he and it were proceeding from a point where their duties had called them to another point to which continuance of their duties required them to go. The question at issue, answered in the negative, was whether or not the injured man, in attempting to ride upon the truck instead of walking, had so far departed from his employment that his injury could not be regarded as arising out of it and in the course of it.

In the Marchiatelb case the injured man was engaged in the performance of his duties as night watchman when he was shot. The pistol, whose bullet occasioned the injury, was one which was kept lying upon a desk in the room in the employer’s temporary construction office located in an outlying district. This room was one of three in the building and was occupied by a foreman and paymaster who, in the latter capacity, frequently had large sums of money in his possession. One Sunday morning a boy who was an employee of the defendant, although not found to have been so employed on the day in question, entered the office and, seeing the pistol on the desk where he had seen it before, was prompted by curiosity to examine'it. During the examination it was accidentally discharged, with the consequence that the employee, who was in the next room, was hit by the bullet. The question presented for decision and affirmatively decided was whether there was a causal connection (using that term in the sense in which it is frequently employed in workmen’s compen *293 sation cases, see Fiarenzo v. Richards & Co., 93 Conn. 581, 107 Atl. 563) between the injury and the injured man’s employment or the conditions of that employment. The claimed analogy between the facts thus recited and those presented by the case at bar, utterly fails, since no one concerned in the present misadventure was, at the time of its occurrence, engaged in the performance of any duty owed to the defendant or in an attempt to advance its interests, and no conditions of the plaintiff’s employment were present in the situation.

In the course of its opinion in the Marchiatello case, the court lays down the guiding principle to be applied in determining whether or not an employee’s injury arises out of his employment, as follows (p. 263): “An injury arises out of an employment when it occurs in the course of the employment and is the result of a risk involved in the employment or incident to it, or to the conditions under which it is required to be performed. The injury is thus a natural or necessary consequence or incident of the employment or of the conditions under which it is carried on. Sometimes the employment will be found to directly cause the injury, but more often it arises out of the conditions incident to the employment. But in every case there must be apparent some causal connection between the injury and the employment or the conditions under which it is required to be performed, before the injury can be found to arise out of the employment.”*

This, we take it, is the statement of principle relied upon by the commissioner and the court below for their conclusion. The conditions stated, however, are not satisfied in the circumstances of the present case. There was no connection between the injury and the plaintiff’s employment or the conditions under which it was required to be performed. It is true that the truck, an instrumentality used in the employer’s business *294 during business hours, played a part in the accident, but it was not such an instrumentality at the timé of the accident, and as neither it nor the plaintiff was engaged, at the time the plaintiff’s injury was suffered, in doing anything connected with the employment or incidental to it, it could not have resulted from a risk arising out of the conditions in which the employment was carried on.

It is, of course, true, as the commissioner points out, that the plaintiff’s right to compensation would not be defeated by either the fact that the defendant did not own the truck, or that the clock indicated that the hour was passed when his day’s work terminated. Carter v. Rowe, 92 Conn. 82, 101 Atl. 491; Merlino v. Connecticut Quarries Co., 93 Conn. 57, 104 Atl. 396; Sala v. American Sumatra Tobacco Co., 93 Conn. 82, 105 Atl. 346. It does not exist because there was no relation of employer and employee between the parties at the time of the injury, and the injuries suffered did not arise out of conditions connected with the injured man’s employment by the defendant. They, on the contrary, arose out of conditions created solely by the entirely independent and voluntary action of parties bearing no present employment relation to that company.

There is error, the judgment of the Superior Court is set aside and the cause remanded for the rendition of a judgment vacating the award of the commissioner.

In this opinion the other judges concurred.
