What can be a result of failing a smog check?

Failing a smog check typically results in the requirement for repairs to be made before the vehicle can be rechecked. This regulation is in place to ensure that vehicles meet environmental standards for emissions. If a vehicle does not pass the smog check, the inspector will usually identify specific issues or components that caused the failure. The vehicle owner is then responsible for addressing these issues and making the necessary repairs. Once the repairs are completed, the vehicle can be retested to ascertain whether it now complies with the emissions standards. This process helps reduce air pollution and ensures that only environmentally compliant vehicles are allowed on the road.

While the other options describe challenges that could arise after failing a smog check, such as potential fines or registration issues, the immediate and necessary action taken after a failure is to address the repairs needed to meet compliance.
