(a) Notwithstanding Section 23575, if a person is required to operate a motor vehicle in the course and scope of his or her employment and if the vehicle is owned by the employer, the person may operate that vehicle without installation of an approved ignition interlock device if the employer has been notified by the person that the person's driving privilege has been restricted pursuant to Section 23575 and if the person has proof of that notification in his or her possession, or if the notice, or a facsimile copy thereof, is with the vehicle.
