CDL Handbooks And Truck Driver Resources For Your State

The CDL Manual, also known as the CDL Handbook, is the training manual you will study in order to pass the written test to obtain your commercial learner's permit. The commercial learner's permit allows you to drive a tractor trailer as long as you have a licensed CDL holder in the vehicle with you.

The CDL manual also contains various sections of required materials for obtaining your CDL endorsements, or CDL certifications, some of which are required for driving a commercial vehicle, others are optional.

You can also pick up a paper copy of the CDL manual from your state's DMV office.
