Following our decision in Rhodes, Inc., v. Raleigh, 217 N.C. 627, 9 S.E. 2d 389, the General Assembly adopted Cb. 153, Session Laws of 1941, now G.S. 160-200 (31), vesting in the municipalities of tbe State authority “to regulate and limit vehicular parking on streets and highways in congested areas.” Tbe Act further provides in part that “in tbe regulátion and limitation of vehicular traffic and parking in cities and towns tbe governing bodies may, in their discretion, enact ordinances providing for a system of parking meters designed to promote traffic regulation and requiring a reasonable deposit (not in excess of five cents per hour) from those who park vehicles for stipulated periods of time in certain areas in which tbe congestion of vehicular traffic is such that public convenience and safety demand such regulation.” See also G.S. 160-501 and sec. 22 (36), Cb. 1184, S.L. 1949 (Charter of City of Ealeigb).
G.S. 160-200 (31) vests tbe City of Ealeigb with authority to divide tbe areas of tbe city congested by vehicular traffic into zones or districts, *6limit the parking of automobiles in such zones as public convenience and safety may demand, install meters in furtherance of the enforcement of such regulations, and require a motorist who leaves his automobile standing in a meter-controlled parking space to put the meter alongside said parking space in operation by depositing the designated coin in the meter at the time he enters the space for the purpose of parking to the end his parking may be timed or measured by the meter for the information of the law enforcement officers of the city.
Pursuant to this authority thus vested in it, the governing body of the City of Raleigh enacted the ordinance which is summarized in the statement of facts, zoning areas congested by automobile traffic and providing for the regulation of parking within said zones by the use of parking meters.
The ordinance adopted creates two criminal offenses material here: (1) parking in a meter-controlled parking space without first setting the meter in operation by depositing in it one of the designated coins; (2) leaving an automobile standing in said space for a period longer than that specified by the ordinance and signs erected for that particular zone.
The defendant is charged with the violation of each of these penal provisions of the ordinance. He was convicted on both counts. He rests his appeal to this Court primarily upon the contentions that (1) the ordinance is invalid as a police regulation, and (2) the City of Raleigh, in adopting the ordinance it now seeks to enforce, exceeded the authority delegated to it by the General Assembly. He states the question presented in this manner: “Does the requirement, on pain of criminal liability, for the deposit of money in a parking meter in order to park an automobile on the public streets for a period of time which varies in accordance with the amount of money deposited have a reasonable relation to the legitimate exercise of police power in the regulation and limitation of vehicular traffic and parking?”
It is suggested, however, that this raises a constitutional question, and courts do not let a case turn on a constitutional question when it may be decided on any other grounds. This is a sound rule when rightly applied. It is bottomed on the philosophy of equality between the legislative, executive, and judicial branches of our government and the system of checks and balances provided by our fundamental law. While we have cited the rule in cases involving municipal ordinances, strictly speaking, it applies only to Acts of the General Assembly — a co-ordinate branch of the government. S. v. Lueders, 214 N.C. 558, 200 S.E. 22; S. v. High, 222 N.C. 434, 23 S.E. 2d 343.
The constitutionality of the enabling statute is not at issue, and there is no sound reason why we should hesitate to determine whether a municipal corporation, a subordinate branch of the government, a creature of *7the Legislature which can exercise only those powers which have been expressly or by necessary implication delegated to it, has exceeded its authority. Madry v. Scotland Neck, 214 N.C. 461, 199 S.E. 618.
It would seem to be clear that this and the companion case against this same defendant, this day decided, are test cases to ascertain to what extent and in what manner the meter method of controlling parking of vehicles in congested areas of municipalities may be accomplished. It is apparent the defendant agreed to become the guinea pig in the test and is co-operating, for he has made material admissions of fact which the State, no doubt, would have found it most difficult to establish if it had been put to proof.
Moreover, the questions here presented are of vital public interest, affecting many of the municipalities of the State. It is a matter of common knowledge that the criminal dockets in the Superior Courts of those counties in which parking meters are used are becoming congested with appeals from city courts in overtime parking eases. Solicitors and judges alike doubt the constitutionality of some of the provisions of the ordinances and the sufficiency of available proof in many cases. At least one judge of the Superior Court has held a similar ordinance unconstitutional in toto and even members of this Court are not in complete accord.
None of the parties are entitled to an advisory opinion from this Court. They have adopted the only method available to them to ascertain the validity of the ordinance. In turn we, in the public interest, must do our part by overlooking nonfatal deficiencies in the record and deciding the essential questions presented to the end any necessary revisions of the ordinance may be made and the officers of the law and the trial courts may proceed to enforce parking regulations with assurance as to their duties and the rights of individual motorists.
While necessity does not create power, it sometimes demands the prompt and effective exercise of power. We must not assume authority we do not possess, but we must at times exercise existing jurisdiction at the first opportunity to the end the executive and legislative branches of the government may know what they may and should do to meet a grave problem of general public concern. This is one of those occasions.
As we said in Insurance Asso. v. Parker, 234 N.C. 20, “The complexity of today’s commercial relations and the constantly increasing number of automobiles render the question of parking a matter of public concern which is taxing the ingenuity of our municipal officials.” Unquestionably, the power to enact laws designed and intended to meet this problem comes within the general authority of the Legislature to enact laws to promote the peace, comfort, convenience, and prosperity of its people. Nscanaba, etc., Trans. v. Chicago, 107 U.S. 678, 27 L. Ed. 442; S. v. Ballance, 229 N.C. 764, 51 S.E. 2d 731. The evils to be remedied are *8proper objectives of legislation enacted under tbe police power of the State.
A municipality is a governmental agency or arm of the State, and so the General Assembly may delegate to a city or town the authority to enact ordinances in the exercise of the police power for the government of those within its limits. Bohn v. Salt Lake City, 8 P. 2d 591, 81 A.L.R. 215. This includes the power to prescribe rules or standards of conduct the violation of which shall constitute a criminal offense. Suddreth v. Charlotte, 223 N.C. 630, 27 S.E. 2d 650.
But this power is subordinate to the constitutional guarantee of equality of privilege and of burden contained in the Fourteenth Amendment to the Federal Constitution. Republic Iron & Steel Co. v. State, 66 N.E. 1005, 62 L.R.A. 136; Smith v. Cahoon, 283 U.S. 553, 75 L. Ed. 1264. Any attempted exercise of the police power which results in the denial of equal protection of the law is invalid. Smith v. Cahoon, supra.
Therefore, an ordinance must be uniform and must have a reasonable relation to the evil sought to be remedied. Its objective must be the elimination of the known evil and must be so designed that it applies alike to all within a designated class. In re Appeal of Parker, 214 N.C. 51, 197 S.E. 706; S. v. Danenberg, 151 N.C. 718, 66 S.E. 301; Shelby v. Power Co., 155 N.C. 196, 71 S.E. 218; Clinton v. Oil Co., 193 N.C. 432, 137 S.E. 183; McRae v. Fayetteville, 198 N.C. 51, 150 S.E. 810; Shuford v. Waynesville, 214 N.C. 135, 198 S.E. 585 ; Rhodes, Inc., v. Raleigh, supra.
Furthermore, a municipality is a mere creature of the Legislature. It has no inherent power and must exercise delegated power strictly within the limitations prescribed by the Legislature. Kass v. Hedgpeth, 226 N.C. 405.
So much for the principles of law which must control decision here. In considering the ordinance under which defendant stands indicted, it must be noted in the beginning that its validity depends, in the first instance, upon whether it meets the condition or limitation contained in the enabling statute, and its enforceability is restricted by the condition imposed by the ordinance itself.
The city may enact a meter control parking ordinance only for those “areas in which the congestion of vehicular traffic is such that public convenience and safety demand such regulation,” G.S. 160-200 (31), and the ordinance is effective “when signs are erected in each block giving notice thereof.” Section 19, Code of Raleigh.
On this record it is apparent that defendant is guilty on the first count and his conviction must be sustained if the provisions of the ordinance under which the charge is laid is valid and enforceable as a penal police regulation. We are of the opinion that it must be so considered.
*9A meter is a mechanical watchman set to time the period of parking in the parking space it is set to watch. It has come into widespread use and is accepted by public officials and motorists alike as a practical solution of the traffic problems involved in areas of cities which are congested by vehicular traffic, and it is now an established part of the traffic control system of many municipalities.
But it is a useless device constituting an unnecessary obstacle to free passage on the sidewalk unless it is set in operation at the time a motorist parks his vehicle. The requirement that the motorist set the meter in operation is a necessary part of the regulation intended and designed to control parking in congested areas and must be upheld as such. We do not deem it unreasonable to require a motorist to perform this service as a condition precedent to his right to park. That this is to be accomplished by the deposit of a coin is immaterial so long as it is a means to that end and not a disguised method of raising revenue.
It is quite true that in all probability some feasible method of setting the meter in operation without requiring the motorist to deposit a coin and thus, in a sense, “pay” for his right to park upon a public street may be devised. But the existence of some other method does not render the action of the board in selecting the coin method void. It had the right, in its discretion, to select the plan which it deemed best under the circumstances.
Of course, the difficulty has been and will continue to be the limitation of the requirement that the meter be set in operation by the deposit of a coin in such manner as to retain the regulation as one designed to promote the public convenience and safety and not to raise revenue. It is valid only so long as its prime purpose is to regulate parking in congested areas, and the maintenance fund derived from the deposit of coins is purely incidental. Here it is not found as a fact, and we find in the record no substantial indication, that the ordinance is a revenue-producing measure rather than a police regulation.
This brings us to the second count in the warrant in which it is charged that defendant parked overtime. He parked only fifteen minutes in a one-hour parking space on a street where the signs give notice that one-hour parking is permitted. Yet he stands convicted on this charge.
Section 19 of the ordinance declares that “when signs are erected . . . giving notice thereof ... no person shall park any vehicle” on Fayette-ville Street “longer than one hour at any one time . . .” Signs have been erected in the block where • defendant’s automobile was parked, giving notice that one-hour parking is permitted in that block. The city board has formally declared in the ordinance that public convenience and safety demand that parking on Fayetteville Street between Morgan and Cabar-rus shall be limited to one hour. In view of these positive provisions of *10the ordinance, is a motorist guilty of overtime parking when he leaves his vehicle standing in a parking space in that zone for only 15 minutes? The answer to this question necessitates a consideration of the provisions of Sections 68 and 69 of the ordinance which declare, in effect, that upon the deposit of only one penny in any meter at a one-hour parking space, lawful parking shall be limited to twelve minutes, and that upon the deposit of a second penny at a later interval the lawful parking time shall be extended to a total of twenty-four minutes. Are these provisions, creating limits within a limit, valid police regulations or do they offend the rule of uniformity as contended by defendant ?
The ordinance contains no declaration that public convenience and safety demand that a motorist shall not park his vehicle in the area which includes the parking space in question for more than twelve minutes or twenty-four minutes. Instead, it declares in positive terms, that cannot be misunderstood, that parking for not more than one hour therein is lawful; that parking for more than that period at any one time is the act that is inconsistent with the demands of public convenience and safety. Likewise, the signs erected and the instructions attached to the meters in that block give notice to the public that one-hour parking in a space set apart therein for that purpose is lawful. ¥e cannot say that the ordinance declares that public convenience and safety require that either twelve minutes or twenty-four minutes shall constitute the period of lawful parking in that block without holding that the provision is written into the ordinance by necessary implication in direct conflict with the positive terms of the law and the signs erected pursuant thereto. And it is axiomatic that penal statutes are construed strictly against the State and liberally in favor of the private citizen. All conflicts and inconsistencies are resolved in favor of the defendant.
Furthermore, to say that public convenience and safety demand that one motorist may not lawfully park his vehicle for more than twelve minutes or twenty-four minutes while another may park an hour in the same space would destroy uniformity, eliminate equality of privilege, and create a serious conflict in the terms of the ordinance itself. The conclusion that parking for one hour in a space set apart for one-hour parking is consistent with the demands of public convenience and yet public convenience requires a motorist to remove his vehicle from the identical space at the end of twelve minutes or twenty-four minutes is so conflicting in content as to be utterly irreconcilable. If public convenience and safety will permit one motorist to park in a given space for the period of one hour, then that privilege must be accorded to all, without additional limitation or restriction, in accord with the requirements of uniformity of right and equality of privilege guaranteed by the Fourteenth Amendment of the Federal Constitution.
*11In providing for the lesser parking limitations, tbe, ordinance itself recognizes and classifies the space as a one-hour parking space and unequivocally bases the lesser periods upon the amount of money deposited in the meter. There is no attempt to evade or camouflage this fact. “Each parking meter shall be so set as to display a signal showing legal parking upon the deposit of a . . . one-cent coin therein for a period of twelve minutes, for that part of the street upon which the meter is placed, for parking within a one-hour parking meter zone . . .” Section 67. “If said vehicle shall remain parked in such parking space beyond the period of . . . twelve minutes upon the deposit of a one-cent coin within a one-hour parking zone . . . such vehicle shall be considered parked overtime . . .” Section 68. “Provided that any owner ... or driver of any vehicle shall be allowed to deposit, at separate intervals, one-cent coin for a period of twelve minutes ivithin a one-hour zo.ne . . . the aggregate deposit not to exceed two one-cent coins for two such parking periods.” Section 69. (Italics supplied.)
Other language used in the ordinance likewise refutes any suggestion that the two lesser parking periods provided for in a one-hour parking space are bottomed on the demands of public convenience and safety. A motorist, upon entering a one-hour parking space for the purpose of parking, “shall, upon entering said parking space immediately deposit a five-cent coin or a one-cent coin, depending upon the length of time said owner . . . driver shall require . . .” Thus the right to select the lesser period is made to rest in the individual motorist and not upon the demands created by congested traffic. While the individual motorist is entitled to every consideration conditions will permit, his requirements or desires cannot be made the basis of penal police regulations. Though he first selects a twelve-minute period when he enters the parking space, his right to remain for the full period of one hour in accord with the ordinance still exists.
Therefore, the conclusion is inescapable that the lawfulness of the parking for the lesser periods of twelve minutes or twenty-four minutes in a one-hour parking space prescribed by the ordinance rests not on the demands of public convenience and necessity required by the enabling-statute and the fundamental law but upon the amount of money deposited in the meter. This will not suffice for the lawfulness of parking cannot be made to depend upon the amount of money deposited in the meter. The maximum length of time the motorist may leave his vehicle standing in a parking space on a public street must be fixed by law.
It follows that since the defendant parked for only fifteen minutes in a one-hour parking space he is not guilty of parking overtime as charged in the second count of the warrant.
*12Tbe vice in the ordinance does not lie in the fact a motorist who intends to park only temporarily is permitted to select a period of parking less than one hour and thereby decrease the amount he is required to deposit in the meter to set it in operation. It lies in the fact that when he once selects a twelve or twenty-four minute period, he is thereafter prohibited, on pain of criminal prosecution, from extending that time by depositing additional pennies, not to exceed a total of five, so as to exercise the privilege granted by the ordinance, the signs erected thereunder, and the instructions attached to the meter. Therefore, it must not be understood that we mean to say that it is improper or unlawful for the city to establish shorter parking periods for one-hour and two-hour parking spaces by nonpenal provisions such as those now contained in its ordinance for the convenience of the motorist, to minimize his contribution to the maintenance fund, and to expedite traffic.
If the motorist permits the meter to register overtime parking, he is subject to citation to court to answer the charge of parking overtime. No doubt the coercive influence of this fact, with its attendant expense and loss of time, will induce most, if not all, motorists to comply strictly with such secondary or incidental provisions. In any event, it is for the city board to balance the advantages and disadvantages which may arise therefrom and decide which is the better course to pursue.
The jury returned a general verdict of guilty. There was no error in the trial with respect to the first count and only a minimum fine was imposed. Under these circumstances no cause for a new trial is made to appear. S. v. Foy, 233 N.C. 228, 63 S.E. 2d 170; S. v. Cobb, 233 N.C. 647, 65 S.E. 2d 131; S. v. Best, 232 N.C. 575, 61 S.E. 2d 612; S. v. Merritt, 231 N.C. 59, 55 S.E. 2d 804; In re McKnight, 229 N.C. 303, 49 S.E. 2d 753; S. v. Smith, 226 N.C. 738, 40 S.E. 2d 363.
The court below will enter a verdict of not guilty on the second count in accord with this opinion. In the trial on the first count we find
No error.
