(1) Doctors of optometry operating mobile units are required to maintain the minimum equipment requirements of WAC 246-851-250 in such units.

(2) Before examining a patient or filling a prescription for a patient, the doctor of optometry must provide to the patient his complete name, his business phone number, the address of his regular office, and his regular office hours. If such doctor of optometry does not maintain a business phone or regular office, he must provide this information to the patient, and must give him his personal phone number and address in place of his business number and address. If the practice of a mobile unit is owned in whole or in part by someone other than the doctor of optometry operating the mobile unit, such fact must also be provided to the patient, along with the names, phone numbers and addresses of all those who own an interest in the practice. The information required by this section may be provided to the patients by means of a sign on or near the mobile unit which the public may reasonably be expected to see and comprehend.
