If, after such an order has been made, a request for a hearing is filed in writing by the person to whom such order was directed, a hearing shall be held in accordance with the provisions of Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code, and the commissioner shall have all of the powers granted thereunder; unless such hearing is commenced within 15 business days after the request is made (or the person affected consents to a later date), such order shall be deemed rescinded.
