Veh. Code, § 15024

Upon application for a license to drive, the licensing authority in a party state shall ascertain whether the applicant has ever held, or is the holder of a license to drive issued by any other party state. The licensing authority in the state where application is made shall not issue a license to drive to the applicant if:

(1) The applicant has held such a license, but the license has been suspended by reason, in whole or in part, of a violation, and if such suspension period has not terminated.

(2) The applicant has held such a license, but the license has been revoked by reason, in whole or in part, of a violation, and if such revocation has not terminated; except that after the expiration of one year from the date the license was revoked, such person may make application for a new license if permitted by law. The licensing authority may refuse to issue a license to any such applicant if, after investigation, the licensing authority determines that it will not be safe to grant to such person the privilege of driving a motor vehicle on the public highways.

(3) The applicant is the holder of a license to drive issued by another party state and currently in force, unless the applicant surrenders such license.
