Which of the following can be operated with a Class C CDL?

Answer: D — All of the above

A Class C CDL is designed to allow the operation of vehicles that do not meet the requirements for a Class A or Class B license. This includes passenger vehicles that are designed to carry 15 or more people and certain vehicles used to transport hazardous materials, provided they are not heavy enough to require a Class A or Class B license. The inclusion of passenger vehicles carrying over 15 people is significant because a Class C license permits drivers to operate such vehicles, which is essential for those driving buses or other large transport vehicles. Additionally, the ability to transport hazardous materials is contingent upon obtaining the appropriate endorsements, but a Class C CDL does allow for the operation of vehicles that may fall under this category, assuming all required regulations and endorsements are met. In essence, a Class C CDL encompasses the operation of various vehicles that do not necessitate a Class A or Class B license, making it a flexible choice for those needing to drive smaller, passenger-type vehicles or transport specific goods. Thus, all of the mentioned options can indeed be operated if you hold a Class C CDL.
