What a planned non-operation actually is
A planned non-operation notice is California's REG 102 PNO. It is not the title. It is not just letting registration lapse.
Is a planned non-operation notice the title? No. People also treat it like just letting the plates expire. Those are different moves.
A planned non-operation notice is the REG 102 Planned Non-Operation Certification. You swear the vehicle will not be operated, moved, towed, or left standing on a California highway for the registration year. Change that status and the renewal is due before it rolls. The same sheet also carries a Certificate of Non-Operation for months already parked. It is not the title. The county still titles it. It is not salvage. It is not a smog certificate. REG 139 is a different sheet.
Why it matters: file after the expiration date and a penalty is due. File on time and DMV keeps the PNO on the record until the vehicle is registered again. A one-day shove down a public road is a Vehicle Moving Permit, REG 172 — not this coupon.
Texas has no planned-non-operation twin. Letting the sticker lapse is just a lapse. Title Only on Application for Texas Title, Form 130-U, is a different paper: title without registration, plates surrendered. Not a yearly park notice.
