This subdivision shall apply only if the employee complies with requirements set forth in paragraphs (1) and (3).(5) This subdivision shall not apply to the operation of a private passenger motor vehicle when operated by an employee, otherwise subject to this section, for the purposes of reporting to or from his or her regularly assigned work location.(c) As used in this section:(1) “Peace officer” means every person defined in Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code.(2) “Policy” shall have the same meaning as defined in subdivision (a) of Section 660.(3) “Private passenger motor vehicle” or “private motor vehicle” means a motor vehicle that is insured under a personal automobile liability insurance policy insuring a single individual or individuals residing in the same household as the named insured, but does not include a vehicle with less than four wheels.(Amended by Stats. 2012, Ch. 823, Sec. 2.
