What does CDL stand for?

Answer: B — Commercial Driver's License

The term CDL stands for Commercial Driver's License. This designation is specifically used to identify a driver's license that is required for operating large or heavy vehicles, such as trucks and buses. The CDL ensures that drivers meet specific safety and performance standards necessary for handling the complexities associated with driving commercial vehicles. The other options provided do not accurately represent the official terminology or the purpose of this type of driver’s license. For instance, "Commercial Delivery License" and "Common Driver's License" do not reflect the standard classifications and regulations associated with commercial driving. Likewise, "Certified Driver's License" misrepresents the formal designation required by law for drivers operating under commercial conditions. Thus, the correct answer is pivotal for understanding the legal and operational framework governing commercial vehicle operation.
