Ins. Code, § 1763.5

In addition to the requirements of Section 1763, no surplus line broker shall solicit from, or place with, any nonadmitted insurer, any insurance covering private passenger automobiles if that insurance contains in whole or in part the limits of coverage provided under the California Automobile Assigned Risk Plan unless the surplus line broker, producing agent, broker, or insured has first submitted to the California Automobile Assigned Risk Plan a properly completed and executed application in accordance with the requirements of the plan for the coverage provided by the plan and the plan itself has determined that the application is ineligible for the limits of coverage applied for and so notifies the surplus line broker or insured in writing.

For purposes of this section, a private passenger automobile includes motorcycles, but does not include a fleet of five or more automobiles rated for business use and used in a business.
