What is a crucial responsibility of apprentices regarding their CDL?

Maintaining a valid Commercial Driver's License (CDL) is essential for apprentices in the field of transportation. It ensures that they are legally allowed to operate commercial vehicles, which is a fundamental requirement of their training and future employment. A valid CDL also indicates that the driver has met all necessary qualifications, including passing required tests and complying with regulations. This responsibility is crucial not only for the apprentice's ability to work but also for safety on the roads, as driving without a valid license can lead to legal repercussions and potential hazards. Keeping the CDL valid is an ongoing duty that underpins all other responsibilities an apprentice might have during their training period and career.
