J. B. DICKENSON, PETITIONER,

v.

W. B. CAHOON, SHERIFF OF DUVAL COUNTY, FLORIDA, RESPONDENT

Davis, J.

The question presented in this habeas corpus proceeding is whether or not the general weight limitation of 16,000 pounds for motor vehicles* licensed to operate on the roads of this State applies to a certificated private contract carrier holding a certificate of public convenience and necessity under Section 4 of Chapter 14764, Acts of 1931.

Section 11 of said Chapter 14764, Acts of 1931, contains two independent paragraphs which, standing set off to themselves although included in a single section of Chapter 14764, supra, read seriatim as follows:

“The vehicle weight of any truck or trailer shall in no event exceed the maximum load weight of 12,000 pounds hereinabove provided unless such load weight be reduced in the amount of such excess vehicle weight.

“The Commission is authorized to prescribe all *157reasonable rules and regulations for distribution of load weight on all trucks and trailers and the specifications and axle spacing in keeping with the physical condition of the public highways and bridges upon or over which such trucks or trailers are authorized to operate. ’ ’

Chapter 14764, supra, was passed by the Legislature and became a law prior to Chapter 15625, supra. It is obvious from a consideration of the history as well as the characteristics of Chapter 14764 as a part of the legislative policy of this State, that said Chapter, dealing as it does with a particular class of vehicles known as certificated vehicles, was intended to create a separate classification of such certificated vehicles for the purpose of regulation, supervision and added taxation. This legislative intent to set up a special code of regulations for certificated vehicles as distinguished from all others licensed to use the highways, is clearly disclosed by Section 8 of Chapter 15625, which provides in part: “but nothing in this Act shall be construed to repeal any part of Senate Bill 411 (Chapter 14764) passed at the regular session of the 1931 Legislature. Provided further that nothing in this Act shall repeal, alter or diminish the mileage tax or fees now provided by law for motor vehicles coming under the supervision of the Railroad Commission of the State of Florida.”

Consequently, we have upon the statute books of this State two separate and independent statutes relating to the supervision and regulation of motor vehicles. The older of these two statutes deals with the licensing, taxation and incidental regulation of motor vehicles of every kind except those subsequently classified and separately dealt with by Chapter 13700, Acts of 1929, and its re-enactment and revision as Chapter 14764, Acts of 1931.

Chapter 14764, Acts of 1931, as a regulatory Act is *158complete in itself. Without reference to any other statute of this State, this special Act dealing with certificated motor vehicles, contains within its four corners, all the principles of regulation and supervision which are to be applied to those certificated vehicles falling within its purview.*

General and Special laws regulating operation of motor vehicles should be construed together, the duty of the Courts being to find a reasonable field of operation for both, without destroying their evident intent, but preserving the force of each, in harmony with the whole course of legislation. See State ex rel. Luning v. Johnson, 71 Fla. 363, 72 Sou. Rep. 477.

We therefore hold that Chapter 14764, Acts of 1931, providing for the supervision and regulation of persons, firms, corporations and associations owning, controlling, operating or managing motor vehicles used in the business of transporting persons or property for compensation over the public highways of this State, providing for regulations of safety and proper operation affecting the use of said highways and the preservation thereof, etc., is an independent statutory enactment, which so far as its regulatory provisions are concerned, was intended to prescribe and put into operation an effective *159scheme of separate regulation and supervision, based upon a special classification of all those vehicles which were required to be certificated under said Chapter 14764, supra, before being granted authority to operate on the highways for compensation.

And that such separate regulation based upon a legislative determination to deal with certificated vehicles as a special class is constitutional, was expressly held by this Court in the two previous cases of Tyson v. Stoutamire, 104 Fla. 505, 140 Sou. Rep. 454, and Riley v. Lawson, opinion filed August 24, 1932, 106 Fla. 521, 143, So. 619.

On the other hand, Chapter 7275, Acts of 1917, as amended by Chapter 8410, Acts of 1921, Chapter 10182, Acts of 1925, and Chapter 15625, Acts of 1931 (now Section 1285 C. G. L., 1011 R. G. S.), is principally a licensing and taxing measure intended for application to motor vehicles generally. The stated statutory regulations set forth in Section 1011 Rev. Gen. Stats., as amended, governing the operation of motor vehicles which are required to be registered and licensed under these statutes, were mainly designed and intended to operate as an incident to defining the scope of the several kinds of licenses which the statute provides to be issued upon payment of the revenue exactions thereby prescribed to be paid upon registration.

Consequently, while the licensing and taxing provisions of amended Section 1011 R. G. S., supra, are applicable to all vehicles using the roads of this State, including those certificated under Chapter 14764, Acts of 1931, as well as others (See State ex rel. McJunkin vs. McLin, Commissioner, 103 Fla. 965, 138 Sou. Rep. 480), the fact that the Legislature in enacting Chapter 14764, supra, deliberately undertook to separately classify, and lay down special regulations concerning the operation of *160certificated vehicles using the highways of this State as the means of conducting a business of haulage for hire, necessarily sets up a new and complete field of regulations for such particular vehicles. This new scheme of regulation, being complete in itself, the effect thereof is to render inapplicable to certificated vehicles those statutory regulations as to weight, speed and the like which for the government of motor vehicles generally have incidentally been included in the licensing and taxation statutes just referred to.*

. Having reached the conclusion just stated to the effect that whatever regulations as to weight limits, speed and the like, must be found in the express or necessarily implied provisions of Chapter 14764, supra, in order to be applicable to vehicles certificated and doing business under Chapter 14764, supra, we turn to a consideration of the last mentioned Act for the purpose of ascertaining *161whether or not it contains within its terms any provision as to weight limits which may be legally applied to a private contract carrier such as the prisoner at the bar seeking his release on habeas corpus purports to be.

Our conclusion on this score is that the last two paragraphs of Section 11 of said Chapter 14764, supra, furnish a complete answer to this question.

By such paragraphs it is provided that the weight of “any” truck or trailer shall in no event exceed the maximum load weight of 12,000 pounds, unless the excess in the vehicle weight be made up by a proportionate reduction in the load weight.

Or to state it in another way, the legal effect of the provision found in next to the last paragraph of Section 11 is to permit a vehicle not exceeding 12,000 pounds in weight to carry a load of not exceeding 12,000 pounds in weight, subject to the proviso that the vehicle weight limit may be increased provided that the weight of the load is reduced in an exact proportion corresponding to the increase in vehicle weight. In practical operation this paragraph means that no combined weight of load and vehicle shall ever exceed 24,000 pounds for a certificated vehicle holding a certificate or permit under Chapter 14764.

Nor is the application of this paragraph limited to certificated vehicles operating only in common carriage.* *162On the contrary, it appears to be clear that it, in terms, applies to “any” truck and trailer, which reference must be construed to mean “any” truck or trailer operating under Chapter 14764, whether in common carriage or in private contract carriage, or in permitted carriage.

Chapter 14764, supra, provides for the issuance of three classes of licenses for use of the highways of this State for the conduct of a business of haulage of persons and property for hire.* But as to each class, it is expressly provided in the statute that the Railroad Commission shall have authority to make rules and regulations “applicable to any and all” auto transportation companies. (Section 7 of the Act). It is furthermore provided that both the statute and the lawful regulations of the Commission thereunder shall be enforceable through criminal proceedings (Section 15) as well as by revocation of the certificate or permit to operate.

In the case at bar the petitioner is charged with the violation of paragraph 4 of Section 1011, Rev. Gen. Stats., as amended by Chapter 15625, Acts of 1931, and not with the violation of any portion of Chapter 14764, Acts of 1931, or any lawful rule or regulation as to weight limits promulgated by the Railroad Commission thereunder, restricting the weight limit of the certificated vehicles of petitioner to an amount under the otherwise permissible statutory gross limit of 24,000 pounds, which is applicable in the absence of some special regulation prescribed by the Railroad Commission within the scope of its power to make reasonable rules and regulations applicable to any and all auto transportation companies.

*163Since the provisions of paragraph 4 of said Section 1011 R. G. S., supra, as amended by Section 3 of Chapter 15625, Acts of 1931, are not applicable to any certificated vehicle subject to regulation under Chapter 14764, Acts of 1931, the stated charge against petitioner fails and he must be ordered discharged from custody.

We are not unmindful of the contention made by the Attorney General and his associate counsel to the effect that Chapters 14764 and 15625 are in pari materia and should be construed together. But even so, an application of thus rule of construction requires us to ascertain and declare a separate field of operation for Chapter 14764 when it is obvious that the legislative intent to provide effective and plenary separate regulations of certificated carriers cannot otherwise be made effective. Payne v. Payne, 82 Fla. 219, 89 Sou. Rep. 538; City of St. Petersburg v. Pinellas County, 87 Fla. 315, 100 Sou. Rep. 509; State v. Simpson, 94 Fla. 789, 114 Sou. Rep. 542.

The argument of petitioner, to the effect that any difference in permissible weight limits for contract carriers as against common carriers, results in an unconstitutional discrimination between the two classes is not passed upon.

Petitioner discharged.
