Wash. Rev. Code § 46.55.115
The Washington state patrol, under its authority to remove vehicles from the highway, may remove the vehicles directly, through towing operators appointed by the state patrol and called on a rotational or other basis, through contracts with towing operators, or by a combination of these methods. When removal is to be accomplished through a towing operator on a noncontractual basis, the state patrol may appoint any towing operator for this purpose upon the application of the operator. Each appointment shall be contingent upon the submission of an application to the state patrol and the making of subsequent reports in such form and frequency and compliance with such standards of equipment, performance, pricing, and practices as may be required by rule of the state patrol.
An appointment may be rescinded by the state patrol upon evidence that the appointed towing operator is not complying with the laws or rules relating to the removal and storage of vehicles from the highway. The state patrol may not rescind an appointment merely because a registered tow truck operator negotiates a different rate for voluntary, owner-requested towing than for involuntary towing under this chapter. The costs of removal and storage of vehicles under this section shall be paid by the owner or driver of the vehicle and shall be a lien upon the vehicle until paid, unless the removal is determined to be invalid.
Rules promulgated under this section shall be binding only upon those towing operators appointed by the state patrol for the purpose of performing towing services at the request of the Washington state patrol. Any person aggrieved by a decision of the state patrol made under this section may appeal the decision under chapter 34.05 RCW.
