delivered the opinion of the Court.
The District Court, composed of three judges, entered a final decree dismissing the bill of complaint which sought to restrain the enforcement of the Motor Vehicle
Section 2 1 prohibits the operation on any highway of any “ vehicle ” as defined, exceeding stated limitations of size, or any vehicle not constructed or equipped as required, and also the transportation of any load exceeding the dimensions and weights prescribed. The State Highway Department may grant permits, for ninety days, for the transportation “ of such overweight or oversize or overlength commodities as can not be reasonably dismantled,” or for the operation “ of super-heavy and oversize equipment ” for the transportation of such commodities, provided that hauls under these permits shall be made “ by the shortest practicable route.”
Section 5 3 prohibits any “ commercial motor vehicle ” (which the Act defines as one designed or used for the transportation of property), truck-tractor, or trailer from operating outside of an incorporated city or town with a load exceeding 7,000 pounds “ on any such vehicle or train or combination of vehicles,” and provides further that no motor vehicle (which includes passenger buses) shall operate outside a city or town with a greater weight than 600 pounds “ per inch width of tire upon any wheel concentrated upon the surface of the highway.”
The District Court made comprehensive findings. These set forth the various interests of the complainant and interveners (common carriers and contract carriers, in intrastate and interstate commerce, and manufacturers and distributors of commodities), their large investments, the extent of their operations in highway transportation, the character and uses of their equipment, and the losses
Of all the registered vehicles on the highways, including trucks, buses and automobiles, less than four-tenths of one per cent, have a rated carrying capacity of more than 7.000 pounds; not more that 5,500 trucks, out of a total of 206,000, have such a capacity and are affected by the prescribed load limit. There are approximately 200,000 miles of state and county highways in Texas and less than 20.000 miles of these are State Designated Highways, the improvement of which represents a public investment of more than $250,000,000. The annual maintenance cost of State Designated Highways for the past three years averaged $12,000,000, and that of the more than 180,000 miles of county highways “ is many millions of dollars annually.” In enacting the statute, “ the Legislature of Texas found as a fact that 7,000 pounds load weight, plus the weight of the vehicle, is the maximum load that should be allowed to pass over the Texas highways, taking into consideration the manner of past and present construction, probable future construction, cost of maintenance, strength of bridges, condition of traffic, etc.,” and this finding of the Legislature is supported by the preponderance of the evidence before the court.
The number of trucks in use in Texas has increased 300 per cent, in the last six years; official registrations show an increase from 65,536 in 1924 to 206,527 in 1930, not including the large increase in interstate truck traffic; and this increase in “truck density” justifies the dimensional and weight restrictions of the statute in the interest of public safety and convenience and highway protection. In 1930, there were only 900 passenger buses operating over the Texas highways, representing less than .004 of one per cent, of the total number of vehicles; these passenger buses, while similar in many respects in construction to trucks carrying freight, are specially equipped to haul passengers, operate under regulations of the railroad commission and under conditions wholly different from those of trucks; that the difference between these two types of vehicles and the number of each type, and in their operation, is ample justification for legislative classification. Excessive loads on trucks are damaging the highways and the limitation of the net load to 7,000 pounds will cause a saving to the State in maintenance costs. Heavily loaded trucks cause accidents and reduced loads will result in greater safety.
In order to carry on the business of farming, “implements of husbandry, plows, threshing machines, hay pressers, etc.” must be moved from one place to another. The same is true of machinery for water-well drilling and highway construction. The uses of the highways for this sort of transportation are temporary only and essential to the public welfare.
The average distance traveled by trucks carrying property from points of origin to common carrier receiving points, or from common carrier unloading points to destination, is from four to eight miles; these hauls are universally short. Such operations are confined to small areas and greatly reduce the danger of traffic congestion or highway injury incident to truck transportation. Those persons coming under the exception permitted by § 5 (b) of the Act transport under distinctly different circumstances from complainant and interveners, who transport over fixed routes, and from other persons using the highways. This exception will have the effect of diverting from the highways generally a great deal of traffic and thus reduce congestion and danger.
There are a large number of commodities “ such as boilers, transformers, telephone poles, etc,, as [sic] cannot be reasonably dismantled ” and which it is necessary to transport. The State Highway Commission in the performance of its duty of issuing special permits under § 2
Upon the facts found, the District Court concluded that the requirements of the statute, aside from § 3, subdivision (f), if independently considered, were reasonable and within the constitutional authority of the State.
The intervener W. T. Stevens, who is engaged in hauling uncompressed cotton, specifically complained of § 3, subdivision (f) as creating an arbitrary and unconstitutional discrimination against him, and the District Court made separate findings upon this point. The court found that the customary square bale of uncompressed cotton is of a greater size than 30 cubic feet and that the average “ square bale of uncompressed cotton, when compressed to a standard density, is less than 30 cubic feet in size ” ; and that the average square bale of cotton whether uncompressed or compressed, weighs approximately 500 pounds or more. There is the further finding that there is no commodity commonly transported over the highways of Texas which conforms to the description — “ contained, boxed or bound in any container, box or binding, containing more than 30 cubic feet and weighing more that 500 pounds ” — other than square bales of uncompressed cotton. The court held that the limitation of the load to “ fourteen packages, boxes, barrels or bales ” exceeding the dimensions stated in § 3, subdivision (f), was reasonable and valid when construed in connection with the provision of § 5 (which became effective January 1, 1932) limiting loads to 7,000 pounds, and expressed the opinion, that 14,000 pounds of uncompressed cotton may be transported under the provisions of § 7 (§ 5b). But the court also held that if § 3 subdivision (f), is construed independently of the provisions of § 5, the former “ has no relation to the supposed mischiefs to be remedied and is unreasonable and unlawfully discriminatory” in its application to the intervener Stevens.
First. The limitation, by § 5, 5 of the net load on trucks to 7,000 pounds is attacked as an arbitrary regulation depriving appellants of their property without due process of law. Appellants urge that this provision repeals the former law which was properly designed to protect the highways and that the drastic requirement of the amendment is opposed to sound engineering opinion; that when gross weight is restricted by the 600 pounds per inch of tire spread upon the highway there is left a sufficient margin to carry greater cargoes than 7,000 pounds without causing damage; and that damage from overweight can be prevented only by regulations which fix a maximum gross load and provide for its proper distribution through axles and wheels to the highway surface.
In exercising its authority over its highways the State is not limited to the raising of revenue for maintenance and reconstruction, or to regulations as to the manner in which vehicles shall be operated, but the State may also prevent the wear and hazards due to excessive size of vehicles and weight of load. Limitations of size and weight are manifestly subjects within the broad range of legislative discretion. To make scientific precision a criterion of constitutional power would be to subject the State to an intolerable supervision hostile to the basic principles of our Government and wholly beyond the protection which the general clause of the Fourteenth Amendment was intended to secure.

The objection to the prescribed limitation as repugnant to the commerce clause is also without merit. The Court, in
Morris
v.
Duby, supra,
at p. 143, answered a similar objection to the limitation of weight by the following statement, which is applicable here: “An examination of the acts of Congress discloses no provision, express or implied, by which there is withheld from the State its ordinary police power to conserve the highways
Third.
The conclusion that the State had authority to impose the limitation of § 5 for the purpose of protecting its highways meets the contention based on the contract clause of the Federal Constitution. Contracts which relate to the use of the highways must be deemed to have been made in contemplation of the regulatory authority of the State. With respect to the power of Congress in the regulation of interstate commerce, this Court has had frequent occasion to observe that it is not fettered by the necessity of maintaining existing arrangements which
Fourth. We are thus brought to the questions raised with respect to the discriminatory provisions of §§ 3, 5 and 7 of the Act, which are assailed as denying to appellants the equal protection of the laws.

provides that the limitations as to size of vehicle shall not apply to
“
implements of husbandry, including machinery used solely for the purpose of drilling water wells, and highway building and maintenance machinery temporarily propelled or moved upon the public highways.” The District Court was of the opinion that the term “ implements of husbandry ” has reference to such implements as “ tractors, plows, trucks, hay presses, etc.” and that the use of the highways for this purpose, as well as for the movement of the described machinery, is but temporary. 56 F. (2d) at p. 190. Appellants urge that any implement, truck or vehicle used by a farmer is an

We do not find the provision of § 3 (c), 8 fixing approximately the same limit of length for individual motor vehicles and for a combination of such vehicles, to be open to objection. If the State saw fit in this way to discourage the use of such trains or combinations on its highways, we know of no constitutional reason why it should not do so.
Objection is made to § 7 (§ 5b)

permitting an additional length of vehicles and greater loads than 7,000
If taken to be sufficiently definite, appellants deny that the exception is justified. The District Court found that it relates to hauls that are universally short, averaging
Another objection to classification is based on the fact that the limitation of § 5
10
applies to “ commercial motor vehicles ” which, as defined in the Act, do not include passenger buses. The latter motor vehicles, while subject to the general limitation of “ 600 pounds per inch width of tire upon any wheel concentrated upon the surface of the highway,” are not subject to a load limit. The District Court found, as above stated, that there were only 900 passenger buses operating over the Texas highways (representing less than .004 of one per cent, of the total number of vehicles) and that the difference between the two types of vehicles and number of each type and in the conditions of operations were such as to support the classification. Appellants press the contention that, as admitted by the District Court, the damage to the highways is as great from a load of persons as from a load of freight, and that the combined weight of vehicles and load in the case of passenger buses is greater than the combined weight of vehicles and load carrying freight where the net load is limited to 7,000 pounds. These considerations would be controlling if there were no other reasonable basis for classification than the mere matter
In view of our conclusion that the limitation in § 5, and the exception in § 7 (§ 5b) are valid, it is unnecessary to consider the question which has been presented as to 'the validity of § 3 (f), if it were regarded as an independent provision, that is, in case the objections to § 5 were sustained. It appears to be conceded that under the ruling of the District Court as to § 5 and § 7 (§ 5b), which we have approved, motor transportation of uncompressed cotton is placed upon an equal basis with other articles of commerce. 56 F. (2d) at pp. 191, 193.
The decree of the District Court is affirmed.
Decree affirmed.

In the instant case, there was evidence that the weight of an average motor truck would be about 11,000 pounds which, added to the 7,000 pounds allowed for net load, would make the limit of gross weight about 18,000 pounds. Other testimony was to the effect that a truck “ usually weighs about the same as the net load,” and upon this assumption it is said that the limit of gross weight would be 14,000 to 15,000 pounds.
