delivered the opinion of the Court.
Defendant in error was tried and convicted before a Justice of the Peace in Cripple Creek, Teller county, upon a complaint in which it was alleged that on November 17, 1959, he drove a motor vehicle while under a suspension order issued by the Motor Vehicle Department of the State of Colorado. The case was appealed to the county court of Teller county where all material facts were agreed to by stipulation of counsel. The pertinent facts are as follows:
On January 10, 1959, on a public highway in Teller county, a horse was struck by a motor vehicle driven by defendant. The director of revenue, upon receiving a report of the accident from one Dobbie, and acting under *212the purported authority of C.R.S. ’53, 13-7-7, suspended the operator’s license which had theretofore been issued to defendant. The suspension followed the failure of defendant to “deposit security in a sum which shall be sufficient in the judgment of the director to satisfy any judgments for damages resulting from such accident as may be recovered * * * ” against the defendant as required by the statute above cited. Defendant admitted receiving notice of the “cancellation” of his operator’s license, and also admitted that notwithstanding the receipt of said notice he thereafter drove a motor vehicle at the time and place named in the summons and complaint filed against him. The sole defense relied upon by him was, and is, that those sections of the Safety responsibility Law, and those statutory provisions purporting to authorize a revocation of defendant’s operator’s license without a hearing or trial, are unconstitutional. The substance of the pertinent statutory provision follows.
Under section C.R.S. ’53, 13-7-6, every operator or owner of a motor vehicle in an accident, accompanied by injury to person or property damages of fifty dollars ($50.00) or more, is required to file with the Motor Vehicle Division of the Department of Revenue, within ten days, a report of what occurred. Failure to file such report is upon pain of having the party’s license summarily suspended — not for fault in the accident, negligent driving or wrongdoing, but merely for failure to obey. By the terms of 13-7-6 the aforesaid report is required to be made to the director of revenue by all parties, whether they are or are not guilty of any violation of a traffic law.
By the terms of C.R.S. ’53, 13-4-26, all required accident reports are secret — “for the confidential use of the department” — “without prejudice to the individual so reporting,” except that by 13-7-33 the essence of the report may be conveyed to any insurance carrier upon *213request and payment of the information fee of twenty-five cents.
According to 13-7-7 the director of revenue is required to suspend the license of every operator and the registrations of every owner of an automobile “in any manner involved” in an accident unless there is a deposit of security referred to as “sufficient in the judgment of the director to satisfy any judgments for damages resulting from such accident as may be recovered against such operator or owner.” This suspension is mandatory. It is not conditioned upon any report being made by the operator whose license is suspended. It is not conditioned upon a criminal trial and a finding of guilt. This suspension must be made within sixty days after the receipt of “a report” —• any report, a true one, a false one, an unsworn one, the report of a bystander or the hearsay report of any kind by any person. A report such as is required by 13-7-6 (viz: by one involved in the accident) is not specified.
Analysis of C.R.S. ’53, 13-7-7, reveals the following characteristics which counsel for defendant contends cannot be sustained.
1. A deposit of security is required regardless of the question of guilt of a violation of a traffic law, and without regard to the question of whether there was any negligence on the part of the person who is required to deposit the security.
2. The deposit is required after the accident and not before it, and operates only to facilitate collection of damages by the party who may thereafter be adjudged entitled thereto. No protection is offered the public with relation to future occurrences.
3. The deposit is required only because of the happening of an accident.
4. The deposit of security is required without any inquiry whatever concerning the liability of the person required to make it, and must be made in such sum as in the judgment of the director of revenue shall satisfy any *214judgment for' damages resulting from the accident, no standards are fixed for the exercise of his discretion, no evidence is taken, and no notice or hearing is afforded as to the amount or nature of the security to be required.
As shown by the stipulated facts, when a report of an accident, which identifies the parties involved, is made to the Motor Vehicle Division of the Department of Revenue, a notice is sent to them by mail. It is called a “Warning of Suspension” by which the parties are informed that if the recipient cannot prove he has insurance covering the accident, he must establish his financial responsibility to the other party to the accident by securing a release from him, or by depositing the amount of money fixed by the director of revenue. In default of which his license to drive a car will be summarily suspended.
Article II, Section 3 of the constitution provides that: “All persons have certain natural, essential and inalienable rights, among which may be reckoned the right * * * of acquiring, possessing and protecting property;- * * * ” A motor vehicle is property and a person cannot be deprived of property without due process of law. The term property, within the meaning of the due process clause, includes the right to make full use of the property which one has the inalienable right to acquire.
Every citizen has an inalienable right to make use of the public highways of the state; every citizen has full freedom to travel from place to place in the enjoyment of life and liberty. The limitations which may be placed upon this inherent right of the citizen must be based upon a proper exercise of the police power of the state in the protection of the public health, safety and welfare. Any unreasonable restraint upon the freedom of the individual to make use of the public highways cannot be sustained. Regulations imposed upon the right of the citizen to make use of the public highways must have a fair relationship to the protection of the public safety in order to be valid.
*215The regulation and control of traffic upon the public highways is a matter which has a definite relationship to the public safety, and no one questions the authority of the General Assembly to establish reasonable standards of fitness and competence to drive a motor vehicle which a citizen must possess before he drives a car upon the public highway. When a citizen meets the standards thus defined in a proper exercise of the police power, he has a right to continue in the full enjoyment of that right until by due process of law it has been established that by reason of abuse of the right or other just cause it is reasonably necessary in the interest of the public safety to deprive him of the right to drive a motor vehicle on the highways. Such action cannot be taken without notice to the party affected and without an opportunity for him to be heard on the question of whether sufficient grounds exist to warrant a revocation of his right to drive a motor vehicle upon the highways of the state. The question of whether a constitutionally guaranteed property right can be denied for some justifiable reason, is essentially a judicial question, and under the doctrine of separation of powers of government it must remain a judicial question. In the instant case Nothaus was denied due process of law. The purported revocation of his license to drive was of no force or effect and was brought about under provisions of a statute which cannot be sustained.
The requirement of C.R.S. ’53, 13-7-7, that the director of revenue, “ * * * shall suspend the license of each operator and all registrations of each owner of a motor vehicle in any manner involved in such accident * * * ” unless such persons deposit a sum “sufficient in the judgment of the director * * * ” to pay any damage which may be awarded, or otherwise show ability to indemnify the other party to the accident against financial loss, has nothing whatever to do with the protection of the public safety, health, morals or welfare. It is a device designated and intended to bring about the posting *216of security for the payment of a private obligation without the slightest indication that any legal obligation exists on the part of any person. The public gets no protection whatever from the deposit of such security. This is not the situation which we find in some states where the statutes require public liability insurance as a condition to be met before a driver’s license will issue. Such statute protects the public. The statute before us is entirely different. In the matters to which we have particularly directed attention, C.R.S. ’53, 13-7-7, is unconstitutional. On a matter so obviously basic and fundamental no additional citation of authority is required. We reach this conclusion notwithstanding the fact that other jurisdictions have seemingly overlooked basic constitutional guarantees which must be ignored in reaching an opposite conclusion.
For the reasons hereinabove stated the judgment of the trial court is affirmed.
