What is a mechanic certification card's status during a station suspension?

During a station suspension, the mechanic certification card's status can indeed be seized. This means that when a station is under suspension due to violations of inspection regulations or failing to meet certain standards, any certifications held by the mechanics at that station could be revoked. This measure is in place to ensure that only qualified and compliant personnel are conducting vehicle inspections. Seizing the mechanic certification card during a station suspension serves as a protective action to maintain the integrity of the inspection process and adhere to safety regulations.

The other scenario choices do not accurately depict the status of the mechanic's certification under these circumstances. For instance, merely reviewing the card does not address the implications of a suspension, and keeping the certification unaffected would undermine the rationale for the suspension itself. Issuing a new card under these conditions would also be contrary to the disciplinary intent behind the station's suspension.
