Service in cases of operation of motor vehicles

[(a)] The use and operation by any person, whether a resident or a nonresident of the State, of any motor vehicle upon a public highway in this State shall subject the person to the jurisdiction of the courts of this State in any action or proceeding against the person growing out of any accident or collision in which the person and the motor vehicle so used and operated may be involved. The use and operation of the motor vehicle is deemed a signification of the person's agreement that any summons against the person which is served is of the same legal force and validity as if served upon the person personally within this State, whether the person is a nonresident of this State or at the time a cause of action arises is a resident of this State but subsequently becomes a nonresident of this State. Service of such summons is to be made as provided by section 634-36, if the defendant cannot be found in the State. [(b)] This section shall not be construed as repealing or amending any other provision of law relating to the service of process nor as establishing an exclusive method of service of process in cases to which this section may apply.
