(Feb. 4, 1887, c. 104, Part II, § 227, as added Aug. 9, 1935, c. 498, § 1, 49 Stat. 567.)”
The main question before us for decision is: Does the Federal Motor Carrier Act confer upon the Interstate Commerce Commission the exclusive power of issuing a certificate of public convenience and necessity to motor vehicles operating upon the highways wholly in interstate commerce? Until this Act was passed by Congress, there was some confusion among the decisions of the courts as to the power of the State to require a motor vehicle operating on the highways wholly in interstate commerce to obtain a permit of public convenience and necessity. Since the enactment of this law, in our judgment, that question is removed, and a decision thereof becomes immaterial.
It is common knowledge that many of the highways in this State were built, and are now being built, with Federal aid, by virtue of and pursuant to Federal laws. Act of July 11, 1916, chap. 241, 39 Stat. at L., 355, as amended February 28, 1919, chap. 69, 40 Stat. at L., 1189, 1200, Comp. Stat., § 7477bb, Fed. Stat. Anno. Supp., 1919, p. 299, and the Federal Highway Act, November 9, 1921, chap. 119, 42 Stat. at L., 212, as amended 23 U. S. C. A., § 1, et seq., Comp. Stat., § 7477-1/4a, Fed. Stat. Anno. Supp., 1921, p. 95.
The laws of Texas embrace a comprehensive program for the building and maintenance of the State’s highways. Some of the Acts are: H. B., 336, Acts 1931, c. 282, and S. B., 11, chap. 42, Gen. Laws of. Texas, 41st Leg., 2d Called Session, 1929, now Article 827a, § 1 et seq. of Vernon’s Annotated Penal Code, and H. B., 335, Acts 1931, c. 277, now Article 911b, Vernon’s Annotated Texas Civil Statutes. We cite some of the leading cases construing these acts. H. B., 336, now part of Article 827a of the Penal Code (Vernon’s Ann. P. C.), was upheld in the following cases: Sproles v. Binford, 286 U. S., 374, 52 S. Ct., 581, 76 L.
