Mrs. Delories Bishop, by next friend, in an action against Carter Contracting Company, a motor common carrier, on account of the death of her husband by reason oí negligence, statutory and simple, of the defendant, recovered a verdict. The defendant’s motion for a new trial as amended was overruled, and the Court of Appeals affirmed the judgment denying a new trial. We granted the defendant’s application for certiorari to the Court of Appeals. A full statement of the facts and questions at issue, and the opinion of the Court of Appeals, will be found in 87
Ga. App.
554 (
The plaintiff in her petition charged that the defendant was guilty of negligence which contributed proximately to the death of her husband, “in that the signal and warning lights on the top and side of the tractor and trailer were not lighted and burning as required by law.” Over objection of the defendant, the trial judge admitted in evidence certain rules of the Georgia Public Service Commission respecting the dimensions of motor vehicles and tractors and trailers, and reflectors and lights on the same as required of motor common carriers. The judge gave the rules of the Public Service Commission in his charge to the jury, and informed them that a violation of any of these rules *920 would constitute negligence per se. The defendant assigned error in its motion for a new trial on these instructions. One of the objections to the instructions given as to these rules was that section 24 of the act of 1931 (Ga. L. 1931, pp. 199-213), which purported to give the Public Service Commission power to promulgate rules and regulations as to lights and reflectors on vehicles used by motor common carriers, has been repealed by the act of 1939 (Ga. L. 1939, pp. 295-303), which fixed a statutory rule as to lights required on all motor vehicles, and placed in the Department of' Public Safety the sole power to make rules as to reflectors on all motor vehicles. The Court of Appeals held that the act of 1939, vesting in the Department of Public Safety authority to determine and specify the type of reflectors to be placed on all vehicles using the highways of this State, did not repeal or supersede section 24 of the act of 1931, so as to deprive the Public Service Commission of its power to promulgate rules and regulations as to number and type of reflectors to be used on vehicles of motor common carriers, and that consequently it was not error to admit in evidence rules of the Public Service Commission in regard thereto, or to charge that a violation of any of these rules would constitute negligence per se.
The act of 1931 has for its purpose the prescribing of conditions and regulations under which common carriers by motor vehicles are permitted to operate upon the highways of this State. The act of 1939 is one to define reckless driving, to restrict the speed on public streets and highways, and to provide for the dimming of lights on motor vehicles; and provided that motor vehicles used on the public highways shall be equipped with reflectors to serve as warning signals to drivers of approaching vehicles, how the minimum requirements shall be determined, and placed in the Department of Public Safety authority to prescribe the type of reflectors to be placed on all vehicles.
For a better view as to the field which these two acts, the act of 1941 (Ga. L. 1941, pp. 449-454), and the rules of the Public Service Commission cover, we set out below in parallel columns their respective provisions, which were introduced in evidence.

(b) The Department of Public Safety is hereby vested with authority to determine and specify the type of reflectors to be placed on vehicles ; to approve reflectors meeting the minimum requirements; and to make such other reasonable rules and regulations needed for the use of said reflectors, (c) The fact that no reflectors or reflectors failing to meet the minimum requirements and approval of the said Department of Public Safety according to the said rules and regulations of the Department, are on the vehicle, shall be considered prima' facie evidence of negligence on the part of the owner of such a vehicle.” Ga. L. 1939, pp. 295-300, Section 5.
“ (b) Provided further that all trucks of more than 1-1/2 ton capacity shall have clearance lights at each extremity *922 in the front and clearance lights at each extremity in the rear. Where the cab of said truck is not as wide as the body said clearance [lights] must be placed at the widest extremity of the body, so as to clearly indicate the width of the truck to approaching traffic from either direction. Said lights not to be of any glaring or blinding nature.” Ga. L. 1939, p. 299, Section 4.
*923 “(a) Every motor vehicle operated on the public streets or highways of this State shall be equipped with two front headlights located near the side extremities of the front, capable of revealing a person, vehicle or object at least five hundred feet (500') ahead in the darkness, and so arranged that at no time will the beam from said lights create a blinding glare or interfere with the vision of the driver of any vehicle approaching within five hundred feet (500') of said vehicle; and any auxiliary headlights in front must be extinguished when within five hundred feet (500') of any vehicle ahead or any congested traffic area; and shall keep them extinguished until passing the approaching vehicle; provided, further, that every such motor vehicle shall be equipped also with a rear light, red in color, and visible for at least two hundred feet (200') in the darkness in the rear; and provided, further, that said lights, both front and rear, when said motor vehicle is being operated on a public street or highway must be lighted one half hour after sunset to one half hour *924 before sunrise and at any other time when vision is restricted for any reason less than five hundred feet (500') along a public street or highway.” Ga. L. 1939, p. 299, Section 4.
“(a) No vehicle shall exceed a total outside width including any load thereon, of ninety-six inches (96"); no vehicle unladen or with load shall exceed a height of 13 feet 6 inches; no vehicle shall exceed a length of 35 feet extreme overall dimensions, inclusive of front and rear bumpers; combinations of vehicles shall consist of not more than two units, and, when so combined, shall not exceed a total length of 45 feet; for occasional movements of materials or objects of dimensions which exceed the limits [herein] provided, a special permit shall be required as now provided by law.

L. 1941, p. 452, Section 4.
“All laws and parts of laws in conflict with this Act be and the same are hereby repealed.” Ga. L. 1939, p. 303, Section 10.
From a comparison of the acts of 1939 and 1941, supra, with the rules of the Public Service Commission, it will be seen that the General Assembly has by statutory provision enacted rules and regulations as to front and rear lights; clearance lights at each extremity of the front and rear of all trucks of more than one and one-half ton capacity; fixed the dimensions as to width and. length of motor vehicles; and invested in the Department of Public Safety authority to determine and specify the type of reflectors to be placed on all vehicles. The violation of a rule promulgated by the Department of Public Safety is made prima facie evidence of negligence on the part of the owner of the vehicle. The act of 1939, applying to all vehicles using the public highways of this State, includes motor common carriers. It is plain that the nature and kind of front and rear lights, clearance lights on all trucks exceeding one and one-half ton capacity, the width and length of motor trucks, are statutory requirements, and supersede the rules and regulations of the Public Service Commission as to these matters. It is further evident that Section 5 (b) of the act of 1939 granted to the Department of Public Safety the power to determine and specify the type of reflectors to be placed on all motor vehicles, and *926 this power is not in the Public Service Commission. It follows that the Court of Appeals erred in holding that the act of 1939 did not repeal section 24 of the act of 1931 as to the matters above referred to.
Having held that the Public Service Commission was without authority to issue the rules complained of, it is unnecessary to pass upon the question of the constitutionality of section 24 of the act of 1931, or upon the validity of rules issued under this section.
The Court of Appeals ruled as follows: “The owner of a truck engaged as a common carrier in this State is not relieved from liability for the death of a guest in an automobile, which was struck by the truck in a collision, because of the fact that at the time of the collision the truck was being driven by an unauthorized person in violation of the owner’s rule, where the regular driver permitted the unauthorized person to drive the track while the regular driver slept in the truck, and the truck was being operated for the benefit of the owner.” The Court of Appeals in its opinion conceded that the above ruling was not supported by any decided case of that court or of this court, and, being impressed by decisions from other jurisdictions, they adopted the rule enunciated in Cain v. Bowlby, 114 Fed. 2d, 519. That case cites decisions from the highest courts of appeal in Minnesota, Iowa, New York, and Maryland. An examination of those cited cases shows that liability was either placed upon the employer because the substitute employee was known to be an incompetent driver, or where, by statute, the owner of a motor vehicle was made liable by reason of the use of a vehicle on the highway for the benefit of the owner or employer. The ruling in the New Mexico case is based upon a homicide statute which imposes liability upon one “who owns any such . . public conveyance at the time any injury is received.”

269 (2) (
In the instant case, at the time of the collision, the employee of the defendant was in charge of the defendant’s motor vehicle under specific written instructions and rules forbidding him to allow any unauthorized person to operate the vehicle. In disobedience of this rule, Tyree turned the operation of the vehicle over to Byrd, the unauthorized driver, who was driving at the time of the collision, Tyree being asleep in a compartment of the vehicle. Tyree’s act in letting Byrd operate the vehicle was not in the scope of his employment, but was in direct violation of his duties. The subsequent failure of Tyree to stay alongside Byrd and supervise his driving of the truck is not an act of the employee which could be chargeable to the employer, Tyree not being employed to supervise or control the operation of the truck by a third person, but to operate it himself, and not to permit any unauthorized person to operate it. Tyree’s action in turning the operation of the truck over to Byrd, being entirely beyond the scope of his employment, was the same as if he had abandoned the vehicle, and the fact that he stayed on the truck and failed to supervise its operation by Byrd did not make his own nonfeasance chargeable to the employer. Nor does the fact that Byrd, in driving the truck, was doing an act beneficial to the employer, of itself impose liability upon the employer, for the reason that Byrd was not a servant or agent of the employer. The liability of an employer for the negligence of his servant is predicated on the basis that his servant, while in the course and scope of his employment, causes the injury, regardless of whether the master benefited from the act or not. The opinion of the Court of Appeals does not hold that the defendant here ratified the conduct of Tyree in employing Byrd, and the evidence is entirely insufficient to show that the defendant, by its acts or conduct, ratified the act of Tyree in this regard.
It follows from what has been said above that the instructions of the court to the jury — that the owner of a vehicle engaged as a common carrier of freight would not be relieved of liability for the death of the plaintiff’s husband, who was struck by the *930 negligence of the driver of the truck, because of the fact that, “at the time the truck was being driven by an unauthorized person in violation of the owner’s rule, where the regular truck driver permitted the unauthorized person to drive the truck while the regular truck driver slept in the truck, and where the truck was at the time being operated in the prosecution of and for the benefit of the owner’s business, where it is shown that the regular truck driver is in the truck and in charge of it on the business of his master, and where it is shown that the regular truck driver failed to exercise ordinary care to supervise and control the conduct of his substitute in the operation of such truck immediately prior to the accident, and where the regular truck driver by the exercise of ordinary care in the supervising and controlling the conduct of his substitute driver could have avoided the collision” — and the ruling of the Court of Appeals upholding such charge, as set out in the first part of this division, were erroneous.
Judgment reversed.
