Frequently Asked Questions
When do I need a Class C CDL instead of a regular license?
You may need a Class C CDL if you drive a vehicle that does not fit Class A or Class B, but is designed to transport 16 or more passengers including the driver, or carries hazardous materials that require placards.
How many questions are on the CDL Class C exam?
The number of questions depends on your state and which endorsements you need. Most drivers will take the General Knowledge test, plus any required endorsement tests such as Passenger, School Bus, or Hazmat.
Can I drive a Class B vehicle with a Class C license?
No. A Class C CDL does not allow you to drive Class B vehicles. To operate larger single vehicles like full-size buses, dump trucks, or large straight trucks, you usually need a Class B CDL.
Is hazmat endorsement required for all Class C drivers?
Only if you plan to transport hazardous materials that require placards. If your job involves hazmat, you will need to pass the Hazmat endorsement test and meet additional requirements.
