What could happen if a for-hire driver fails to renew their endorsement?

If a for-hire driver fails to renew their endorsement, facing a fine is indeed a consequence they may encounter. In Indiana, maintaining a valid for-hire endorsement is crucial for compliance with state regulations governing commercial driving. If the endorsement expires, the driver is operating without the necessary certification, which can lead to legal penalties, including fines.

On the other hand, continuing to operate legally without a renewed endorsement is not permissible as doing so would violate commercial driving regulations. The automatic loss of a job isn't guaranteed since it depends on the employer's policies, and the assertion that nothing happens because it is not monitored neglects the legal framework put in place to ensure public safety and regulatory compliance. Therefore, the correct answer highlights the importance of adhering to renewal requirements to avoid penalties.
