We will first discuss the question as to whether the court erred in overruling the defendants’ general demurrer. As to this question the allegations of fact in the petition are very similar to the allegations of fact in
Williams
v.
Grier,
196
Ga.
327 (
In the instant case the petition charged the defendants, at the time of the collision, with having violated the ordinances of the City of Thomson, the regulations of the Public Service Commission, and the laws of Georgia, as well as with negligence under the common law. This is permissible.
Williams
v. Grier, supra. Since we have set out the allegations of negligence, we will not repeat them here. The petition also charged that the driver of the gasoline truck which collided with the ambulance, as well as the driver of the ambulance, were guilty of negligence per se. On this point the court ruled in the
Williams
case as follows: “But the defendants themselves were violating a municipal ordinance; and this being true, it was incumbent upon them to anticipate that others, like themselves, might disobey traffic laws and regulations.

v.
Smith,
78
Ga.
694 (4) (
We come next to consider whether the court committed reversible error in overruling the demurrer, the objections to, and the motion to strike paragraphs 1, 2, and 3 of the amendment, (a) It is contended that rule 19 of the Public Service Commission relative to stopping, increasing the speed of, or changing the course of vehicles, if valid, is for the benefit of vehicles following, and not applicable to vehicles on intersecting highways. It is contended that it does not appear from the petition just where the truck of the defendants was parked, and it does not affirmatively appear that the ambulance in'which the plaintiff was riding was following the truck of Eeliable Transfer Company; and that rule 35 of the Public Service Commission is not applicable because no one here involved under the allegations of the petition is of the class for whose benefit this regulation was made. While these contentions are true as abstract principles of law, we can not agree with able counsel for the defendants that they are applicable under the facts of the instant case. We are of the opinion that the petition sufficiently located the truck to invoke these rules, and if the evidence sustained such allegations, this would be a sufficient basis for recovery. (b) It is urgently contended by the defendants that the Code, §§ 68-603, 68-627, and 68-629 are unconstitutional and in violation of art. 3, sec. 1, par. 1 of the constitution of the State of Georgia (Code, § 2-1201), in that such sections attempt to delegate to the Public Service Commission the power to legislate, and that all rules and regulations pursuant to such laws are void. Counsel contends that this specific question has not been passed on by the Supreme Court of Georgia. Numerous decisions are cited, dealing with the question as to just how far, under the provisions
*624
of the State Constitution, the legislature can go in delegating its authority tó a commission without violating such constitutional provision. The question before us is not so much the problem of how far the legislature may go in that field, but rather what authority this court has to determine as to the constitutionality of a rule passed by a commission to which such authority has been delegated.
