delivered the opinion of the court:
Cecil Warren, plaintiff in error, was charged with and fined $50 for violating the provisions of section 121.02 of the Uniform Act Regulating Traffic on Highways. This section was amended July 15, 1955. (Ill. Rev. Stat. 1955, chap. 95½, par. 218b.) He appeals directly to this court, and we have jurisdiction because the sole question presented is the constitutionаlity of the section which reads as follows:
“It is unlawful for any person to operate any new motor vehicle of the second division which is purchased on and after September 1, 1955, or any motor vehicle of the second division the splash guards of which have been replaced on and after Seрtember 1, 1955, which replacement shall be necessary when present splash guards are unable to prevent the splashing of mud or water upon the windshield of other motor vehicles, upon the highways of this State outside the corporate limits of a city, village or incorporated town, unless such vehicle is equipped with rear fender splash guards which shall comply with the specifications as hereinafter provided and such splash guards shall be so attached as to prevent the splashing of mud or water upon the windshield of other motor vehicles; provided, that on and after January 1, 1957, this amendatory Act оf 1955 shall apply to all motor vehicles of the second division.
“The rear fender splash guards shall contour the wheel in such manner that the relationship of the inside surface of any such splash guard to the tread surface of the tire or wheel shall be relatively parallel, both laterally and across the wheel, at least throughout the top 90 degrees of the rear 180 degrees of the wheel surface and the downward extension of the curved surface shall extend to a length which shall end not more than ten inches from the ground.
“Such splash guards shall be wide enough to cover the full trend |>zc] or treads of the tires being protected and shall be installed close enough to the tread surface of the tire or wheel as to control the side-throw or wash of the bulk of the thrown road surface material and keep such bulk within a tangent not to exceed 15 degrees measured from a base line formed by the top height of the wheel.
“Such splash guards may be constructed of a flexible material, but shall be attached in such a manner that, regardless of movement, either in such splash guards or the vehicle, such splash guards will retain their general parallel relationship to the tread surface of the tire or wheel under аll ordinary operating conditions.
“This Section shall not apply to motor vehicles whose construction does not require such splash guards, nor to motor vehicles in transit and capable only of using temporary splash guards approved by the Illinois State Highway Police.”
The validity of this section is challenged on grounds which we shall hereinafter consider separately. The motor vehicle in question is one of the second division — vehicles designed and used for pulling or carrying freight and also vehicles or motor cars which are designed and used for carrying more than seven persons. (Ill. Rev. Stat. 1955, chap. 95½ par. 99.) No controverted fact questions are involved.
Every presumption is in favor of the validity of a statute enacted under the police power. (Gadlin v. Auditor of Public Accounts,
No person has the right to conduct a business upon the public highways or to devote them to private gain except as the State, by acquiescence or by law, may permit it. (Hayes Freight Lines, Inc. v. Castle,
The measure of the reasonableness of a police regulation is not necessarily what is best but what is fairly appropriate to the purpose of the aсt under all circumstances. (Keig Stevens Baking Co. v. City of Savanna,
In the present case plaintiff in error does not question the right of the legislature to provide for and regulate the use of splash guards on motor vehicles. He poses only the question whether the legislature has properly exercised its power by the adoption of the section of the statute under attack in its present form. Tested by the rules of constitutional interpretation alluded to above, we find no merit in the contention that the provisions of that section are unreasonable, arbitrary and capricious. The splashing of water or mud upon the windshields of other vehicles on the road is an evil which the legislature rightfully aims to correct. We can give no weight to the contention of the plaintiff in error that the “mud flaps” which were required upon all trucks under the 1951 statute are to be preferred as more simple and inexpensive. It is within the power оf the legislature to solve safety problems, by whatever means it deems best, SO' long as such means reasonably tend to correct the evil. Since this police regulation is fairly appropriate to the expressed purpose of the statute, it is immaterial so far as the court is concerned, whether it is the best possible means or is inferior to the 1951 enactment which it supplants.
The claim that this statute is “impossible of construction” and “requires the doing of an act in terms so vague that men of common intelligence must necessarily guess at their meaning,” is equally without merit. The requirements and specifications fоr the splash guards are intelligible and ascertainable and the standards for their implementation are fully spelled out. The record shows that, without any difficulty, there can be compliance.
The complaint that this act delegates legislative authority to administrative officials, and is therefore invalid, is not substantiated. It is necessary to distinguish between the delegation of true legislative power and the delegation to a subordinate of authority to execute the law. (Lydy, Inc. v. City of Chicago,
The constitution does not require the General Assembly to establish all-embracing absolute criteria whereby every detail and circumstance necessary in the enforcement of the law is anticipated; intelligible standards to guide the agency charged with the enforcement are sufficient. Hayes Freight Lines, Inc. v. Castle,
The act in question delegatеs no power to make the law; it merely imposes upon the Illinois State Highway Police the duty and authority of approving temporary splash guards for motor vehicles in transit. The term “vehicles in transit” is defined by statute. It means those towed or carried. (Ill. Rev. Stat. 1955, chap. 95½, par. 19.) The General Assembly is not required tо concern itself with the myriad of transitory circumstances to be encountered. It may confer reasonable discretion upon the proper agency as to the execution of the law. The ministerial duty of approving temporary splash guards for “in transit” trucks is properly delegated to the оfficials on the spot. The legislature could hardly do this, so it must fall in that twilight area where some discretion is left to the police.
Complaint is made that the statute is discriminatory and that there is no rational basis for the classification between those vehicles which require splash guards and those which do not. A valid and justifiable classification must be based on a real and substantial difference having a rational relation to the subject of the particular legislation. (Hansen v. Raleigh,
This classification is reasonable and is based on substantial differences which have a rational relation to the subject matter. This difference is inherent in the two classes of vehicles — bearing in mind the expressed purpose of the regulation, namely, those vehicles required to have splash guards and those whose construction offers ample protection. Vehicles designed to carry not more than seven passengers, commonly cаlled pleasure cars, are constructed so that no splash guards are necessary. While no evidence was offered on the subject the construction of pleasure cars is quite universally known. Judges are not supposed to know less than the average persons. We take judicial notice of the difference between vehicles of the first and those of the second division so far as the need for splash guards is concerned.
Similar considerations justify special treatment of trucks “in transit,” (hereinabove described,) which are being transported from the factory to the dealer usually with a temporary in-transit permit rather than a regular license. Clearly, it is not an unreasonable classification to permit the installation of temporary splash guards for the purpose of this single trip.
In Hansen v. Raleigh,
Plaintiff in error relies principally on Consumers Co. v. City of Chicago,
The challenged act is a proper exercise of the police power of the State and is free from any unconstitutional taint.
The judgment of the county court of St. Clair County is affirmed.
Judgment affirmed.
