During what time frame must a vehicle pass a Smog Check after initial failure?

A vehicle that fails a Smog Check must be retested generally within 90 days to avoid additional penalties. This time frame is set to encourage prompt follow-up on repairs and ensure that vehicles are timely brought into compliance with emissions standards. If a vehicle owner allows more than 90 days to pass, they may incur additional penalties, such as late fees or fines, which can complicate the registration process.

The 90-day period serves as a practical guideline for both vehicle owners and inspection stations, enabling the efficient management of emissions compliance while providing vehicle owners the opportunity to address any identified issues effectively. Keeping the retesting window relatively short also aids in maintaining cleaner overall air quality by ensuring that problematic vehicles are not on the road longer than necessary.
