We granted the writ of certiorari in this case (Undercofler v. L. C. Robinson & Sons, Inc., 111 Ga. App. 411, 141 SE2d 847) to study the Act of 1963 (Ga. L. 1963, pp. 30, 31) which further amended § 68-502 of the Code of 1933 and, after a careful study and consideration of the amendment, we have reached the conclusion that its only purpose was to add another class of motor carriers for hire to those which § 68-502 had previously exempted from regulation by the Public Service Commission; and having reached *392this conclusion, we are of the opinion that the Court of Appeals properly reversed the judgment of the trial court.

Judgment affirmed.
