Five Pieces of Paper Worth Recognizing
The DMV publishes hundreds of forms and you will encounter perhaps five. Recognizing them on sight — and knowing which are urgent — saves a great deal of confusion.
The SR-1
Report of traffic accident occurring in California. This is the report Vehicle Code section 16000 requires after a collision involving injury, death, or property damage above the threshold the DMV publishes. Due within ten days, owed regardless of fault, and not satisfied by a police report. If you take one thing from this page, take this one: the SR-1 is a deadline, not a formality.
The SR-22
Proof of financial responsibility certificate. Not a form you fill in — your insurer files it with the DMV to certify that a policy meeting the requirements is in force, and it tells the department if the policy ends. It attaches to a person rather than to a vehicle, and it exists because the DMV has required proof for a period.
The notice of transfer and release of liability
Form REG 138. The seller's filing under Vehicle Code section 5900 that records the vehicle leaving your hands. Filed online in minutes, and the single best protection against citations from a car you no longer own. File it the day of the sale.
The planned non-operation certification
The filing that tells the department a vehicle will not be driven, parked or left standing on a public road during the registration period. It has to be filed within the DMV's window, which is tied to the registration expiry date.
The change of address
Not glamorous and quietly the most consequential, because every notice the department sends you goes to the address on file. California's published requirement is to notify the DMV within ten days, and your driver record and vehicle records are updated separately.
How to use this list
Two of these are deadline-bearing — the SR-1 and the planned non-operation certification. One protects you from other people's behaviour — the notice of transfer. One follows a DMV requirement rather than starting one — the SR-22. And one determines whether you ever see the others in time.
Form numbers and filing windows are exactly the sort of thing the department revises, so use the DMV's own site for the current version rather than a link someone sent you in 2019.
If your situation involves the SR-22 in particular, we file those regularly and can tell you what it adds before you commit.

Do I file the SR-22 myself?
No. Your insurance company files it with the DMV against a policy that meets the requirements, and it also notifies the department if that policy ends.
Is the SR-1 the same as a police report?
No, and one does not substitute for the other. The SR-1 is your own report to the DMV under Vehicle Code section 16000, due within ten days of a qualifying collision.
Where do I get the current forms?
From the DMV's own site. Form numbers and requirements change, so avoid third-party copies and saved links.
