(1) If the patrol approves the initial application, the applicant will be issued a temporary permit for the vehicle(s) which will be valid for thirty days, during which time the emergency equipment may be installed for the purpose of inspection. After installation of the emergency equipment, the applicant must bring the vehicle to a district or detachment office of the patrol to be examined by any patrol officer to verify the location, make, model, and color (if applicable) of the emergency equipment. A patrol officer will certify the results of this examination on a form prescribed and provided by the patrol and the applicant must file the form with the patrol. Original forms may be mailed to the patrol at the Equipment and Standards Unit, General Administration Building, P.O. Box 42600, Olympia, WA 98504-2600 or the electronic record of the form may be emailed to equipment@wsp.wa.gov. Upon the patrol's receipt of such certification, the patrol will review the documentation and may issue a vehicle permit, which must be carried in the vehicle at all times, and expires when:

(a) The vehicle is removed from the permit; or

(b) The authorized emergency vehicle permit is terminated by the applicant or by the patrol; or

(c) The authorized emergency vehicle permit expires, which will be one year from the date of issuance thereof.

(2) A request to add a new vehicle may be made at any time in writing to the patrol and must include the vehicle year, make, model, VIN, license number, and registered owner. The requests will be processed as outlined in subsection (1) of this section. A vehicle will not be allowed to operate under a permit until the vehicle has been authorized by the patrol and issued a vehicle permit under the applicant's authorized emergency vehicle permit.

(3) A request to add new equipment to a vehicle with a current permit may be made at any time in writing to the patrol. If additional equipment other than that approved under the vehicle permit must be installed:

(a) A new certificate of equipment must be filled out for the vehicle and the patrol must inspect and approve such equipment issuing a new vehicle permit prior to use of the vehicle under the authorized emergency vehicle permit.

(b) The applicant may be required to obtain authorization from each primary jurisdiction of the geographic areas listed in the authorized emergency vehicle permit if the additional equipment was not previously authorized under the current permit.

(4) A copy of the vehicle permit and current authorized emergency vehicle permit(s) the vehicle is authorized under must be carried in the vehicle at all times and presented to law enforcement upon request.
