How do you become a class B driver?

Becoming a Class B driver requires a Class B commercial driver's license (CDL). You can apply for a CDL or truck-driving program where you will learn the information and skills to pass your state written knowledge test and driving exam. After you have your license, you can begin applying for Class B driver jobs. Federal regulations require you to be at least 21 years old for interstate commercial driving. Some states allow you to be 18 years old for intrastate driving. Some employers may require a high school diploma or equivalent.
