Does a Phone Photo Count as Proof?
Short answer: California accepts electronic proof of insurance. Showing the card on your phone is valid — you don't need the paper one.
What the law requires
Vehicle Code section 16028 requires drivers to carry evidence of financial responsibility and to provide it when a peace officer asks, and again if you're involved in a collision. The section says in terms that the evidence may be provided using a mobile electronic device — so the photo, the PDF and the insurer's app all do the same legal job as the printed card.
This is settled law rather than an officer's courtesy. If you have a current card on your phone and can display it, you've met the requirement.
Handing over your phone
You're producing a document, not surrendering a device, and the statute is explicit: section 16028 provides that the peace officer shall only view the evidence of financial responsibility and is prohibited from viewing any other content on the mobile electronic device.
Knowing that changes how the moment feels. Open the card first, then hand the phone over — or hold it and show the screen.
At a collision you owe it to the other driver too
This part gets missed. Vehicle Code section 16025 requires every driver involved in an accident to exchange, with the other drivers and property owners present, their name and address, driver's license number, the vehicle identification number, the registered owner's address, and evidence of financial responsibility — including the insurance company's name and address and the policy number.
It isn't optional politeness: the section makes failing to do it an infraction, punishable by a fine of up to $250. A card on your phone satisfies it in seconds, provided you can actually open the thing.
Save it where it opens without a signal
The realistic failure here isn't legality, it's access. A card living in an email thread, or in an app that wants to log in first, is no help in a parking garage with no bars.
Screenshot it into your photos, or use your carrier's offline card if the app has one, and know which you'd reach for. Proof you can't display isn't proof.
Keep a paper copy anyway
Phones die, screens crack, and batteries pick their own moments. A card in the glovebox costs nothing and covers all three.
Make sure it's current
An expired card is not proof of current coverage. When the policy renews, replace the saved image the same day — a stale screenshot is exactly the version people discover at the roadside, months after a renewal they'd stopped thinking about. If you can't find a current one, ask your agent.

Do I still need the paper card?
Not legally, since electronic proof is accepted. Keeping one is still sensible in case your phone is dead.
What if my phone won't load the app?
That's the argument for a saved screenshot or a paper copy. Proof you can't display isn't much use.
Does an expired card count?
No — it must reflect current coverage. Update the saved copy every renewal.
