How to Obtain a Class B License in California

A commercial driver's license is a necessity for certain types of jobs. California divides its commercial driver's licenses into classes. With a Class B Commercial Driver's License you may drive a bus (other than a trailer bus), a single vehicle with a GVWR of more than 26,000 lbs, a 3-axle vehicle weighing over 6,000 pounds, a farm labor vehicle and any vehicle that a Class C driver is permitted to drive. Below are instructions on how to apply.

Tips and Warnings

California has established an alternative to the DMV road test. You may submit a Certificate of Driving Skill (DL 170) issued by your employer if the DMV has authorized your employer to issue one.

Under federal law, you must be at least 21 years old to drive a commercial vehicle across a state line. There are also certain additional qualifications necessary for a Class B driver to drive a bus or a farm labor vehicle.
