What must Engineers be prepared to do with their certification card?

Engineers must be prepared to display their certification card upon request. This practice ensures compliance with regulatory requirements and helps maintain safety standards within the operational environment. Having the card available for inspection allows for verification of an engineer's qualifications and competency, which is vital in maintaining trust and accountability in railway operations. It is part of the protocols designed to ensure that qualified personnel are overseeing activities, which directly impacts the safety and efficiency of the entire operation.

While other choices touch on aspects of certification, they do not reflect the immediate requirements of displaying the card when requested by supervisors or inspections. Keeping the card at home does not facilitate immediate verification, and submission or renewal processes are usually governed by specific administrative timelines rather than immediate operational readiness.
