What is one requirement to operate a vehicle as part of a CDL training program?

Answer: B — Must have a valid driver's license

To operate a vehicle as part of a Commercial Driver License (CDL) training program, holding a valid driver's license is essential. A valid driver's license ensures that the trainee has completed the necessary foundational driving skills and understands basic road rules and regulations. This foundation is critical for progressing into more advanced training required for operating commercial vehicles, which have additional complexities compared to standard vehicles. Having a valid driver's license indicates that the individual has already passed the necessary evaluations regarding general driving capability, thus allowing them to focus on learning the specific skills required for operating commercial vehicles without needing to relearn basic driving principles. This requirement underscores the importance of basic driving proficiency before entering specialized training that is necessary for commercial driving.
