(1)(a) A nonresident accepts the rights and privileges conferred by law in the use of the public highways of this state, as evidenced by:
(i) Operation of a vehicle thereon; or
(ii) The operation thereon of the nonresident's vehicle with the nonresident's consent, express or implied.
(b) Acceptance under (a) of this subsection shall be deemed equivalent to and construed to be an appointment by such nonresident of the secretary of state of the state of Washington to be the nonresident's true and lawful attorney upon whom may be served all lawful summons and processes against the nonresident growing out of any accident, collision, or liability in which such nonresident may be involved while operating a vehicle upon the public highways, or while the nonresident's vehicle is being operated thereon with the nonresident's consent, express or implied.
(2) Operation and acceptance under subsection (1) of this section shall be a signification of the nonresident's agreement that any summons or process against the nonresident which is so served shall be of the same legal force and validity as if served on the nonresident personally within the state of Washington.
(3) A resident of this state appoints the secretary of state of the state of Washington as the person's lawful attorney for service of summons or process as provided in this section for nonresidents, if the resident, while operating a motor vehicle on the public highways of this state:
(a) Is involved in any accident, collision, or liability; and
(b) Thereafter at any time within the following three years cannot, after a due and diligent search, be found in this state.
(4) Service of such summons or process under subsections (1) and (3) of this section shall be made by leaving a copy for record and for each address to be served thereof with a fee established by the secretary of state by rule with the secretary of state of the state of Washington, or at the secretary of state's office.
(5) Service under subsection (4) of this section shall be sufficient and valid personal service upon said resident or nonresident provided that:
(a) Notice of such service and a copy of the summons or process is forthwith sent by registered mail with return receipt requested, by plaintiff to the defendant at the last known address of the said defendant; and
(b) The plaintiff's affidavit of compliance herewith are appended to the process, together with:
(i) The affidavit of the plaintiff or plaintiff's attorney that the plaintiff or plaintiff's attorney has with due diligence attempted to serve personal process upon the defendant at all addresses of the defendant known to the plaintiff or attorney;
(ii) A further listing in the plaintiff or plaintiff's attorney's affidavit of the addresses at which the plaintiff or attorney attempted to have process served; and
(iii) If there are no known addresses, a statement to that effect within the plaintiff's or plaintiff's attorney's affidavit.
(6) If process is forwarded by registered mail and the defendant's endorsed receipt is received and entered as a part of the return of process then the affidavit required in subsection (5) of this section need only show that the defendant received personal delivery by mail. However, personal service outside of this state in accordance with the provisions of law relating to personal service of summons outside of this state shall relieve the plaintiff from mailing a copy of the summons or process by registered mail as provided in this section.
(7) The secretary of state shall, within eight business days, send one of such copies provided under subsection (4) of this section by mail, postage prepaid, addressed to the defendant at the defendant's address, if known to the secretary of state.
(8) The court in which the action is brought may order such continuances as may be necessary to afford the defendant reasonable opportunity to defend the action.
(9) The fee paid by the plaintiff to the secretary of state shall be taxed as part of the plaintiff's costs if the plaintiff prevails in the action.
(10) The secretary of state shall keep a record of all such summons and processes, which shall show the day of service.
