Section 28.20.400 - Self-insurers(a) A person in whose name more than 25 vehicles are registered in this state may qualify as a self-insurer by obtaining a certificate of self-insurance issued by the department as provided in (b) of this section. A person in whose name 25 or fewer vehicles are registered qualifies as a self-insurer and shall be issued a certificate of self-insurance if the person provides proof satisfactory to the department that the person has and will continue to have the ability to pay a judgment for property damage, bodily injury, or both, in the amount of at least $125,000.(b) The department may issue a certificate of self-insurance when it is satisfied that the person has and will continue to have ability to pay judgments obtained against the person. The certificate may be issued authorizing a person to act as a self-insurer for either property damage or bodily injury, or both, or within the limits the department prescribes.(c) Upon not less than 10 days' notice and a hearing pursuant to the notice, the department may upon reasonable grounds cancel a certificate of self-insurance. Failure to pay a judgment within 30 days after judgment becomes final is a reasonable ground for the cancellation of a certificate of self-insurance.
