Veh. Code, § 16028

(a) Upon the demand of a peace officer pursuant to subdivision (b) or upon the demand of a peace officer or traffic collision investigator pursuant to subdivision (c), every person who drives a motor vehicle upon a highway shall provide evidence of financial responsibility for the vehicle that is in effect at the time the demand is made. The evidence of financial responsibility may be provided using a mobile electronic device. However, a peace officer shall not stop a vehicle for the sole purpose of determining whether the vehicle is being driven in violation of this subdivision.

(b) If a notice to appear is issued for any alleged violation of this code, except a violation specified in Chapter 9 (commencing with Section 22500) of Division 11 or any local ordinance adopted pursuant to that chapter, the cited driver shall furnish written evidence of financial responsibility or may provide electronic verification of evidence of financial responsibility using a mobile electronic device upon request of the peace officer issuing the citation. The peace officer shall request and verify the driver’s evidence of financial responsibility, as specified in Section 16020. If the driver fails to provide evidence of financial responsibility at the time the notice to appear is issued, the peace officer may issue the driver a notice to appear for violation of subdivision (a). The notice to appear for violation of subdivision (a) shall be written on the same citation form as the original violation.

(c) If a peace officer, or a regularly employed and salaried employee of a city or county who has been trained as a traffic collision investigator, is summoned to the scene of an accident described in Section 16000, the driver of a motor vehicle that is in any manner involved in the accident shall furnish written evidence of financial responsibility or may provide electronic verification of evidence of financial responsibility using a mobile electronic device upon the request of the peace officer or traffic collision investigator. If the driver fails to provide evidence of financial responsibility when requested, the peace officer may issue the driver a notice to appear for violation of subdivision (a). A traffic collision investigator may cause a notice to appear to be issued for a violation of subdivision (a), upon review of that citation by a peace officer.

(d) (1) If, at the time a notice to appear for a violation of subdivision (a) is issued, the person is driving a motor vehicle owned or leased by the driver’s employer, and the vehicle is being driven with the permission of the employer, this section shall apply to the employer rather than the driver. In that case, a notice to appear shall be issued to the employer rather than the driver, and the driver may sign the notice on behalf of the employer.

(2) The driver shall notify the employer of the receipt of the notice issued pursuant to paragraph (1) not later than five days after receipt.

(e) A person issued a notice to appear for a violation of subdivision (a) may personally appear before the clerk of the court, as designated in the notice to appear, and provide written evidence of financial responsibility in a form consistent with Section 16020, showing that the driver was in compliance with that section at the time the notice to appear for violating subdivision (a) was issued. In lieu of the personal appearance, the person may submit by mail to the court written evidence of having had financial responsibility at the time the notice to appear was issued. Upon receipt by the clerk of that written evidence of financial responsibility in a form consistent with Section 16020, further proceedings on the notice to appear for the violation of subdivision (a) shall be dismissed.

(f) For the purposes of this section, “mobile electronic device” means a portable computing and communication device that has a display screen with touch input or a miniature keyboard.

(g) For the purposes of this section, when a person provides evidence of financial responsibility using a mobile electronic device to a peace officer, the peace officer shall only view the evidence of financial responsibility and is prohibited from viewing any other content on the mobile electronic device.

(h) If a person presents a mobile electronic device pursuant to this section, that person assumes all liability for any damage to the mobile electronic device.
