Q: My vehicle passed the inspection, what do I do next?
A: Once the inspection is completed and vehicle passes a smog certificate is electronically sent to DMV. So all you need to do is just pay your registration and if required provide DMV with proof of insurance.
We'll also give you a copy of the inspection report with emission readings and reference numbers for DMV records which you can keep as a proof in case DMV computers crash. Not likely to happen, but still it's a good to have. Also if you're AAA member you complete your registration at one of their offices or another option would be visiting DMV online registration renewal website or calling them at 800.777.0133 - if you're patient enough you'll get to talk to somebody.
Your smog check certificate if valid for two years or if you're transferring title for 90 days.
