What Are the Requirements?

There are several federally mandated requirements that you will have to meet before being issued a CDL. These requirements were put in place to protect not only you the applicant but to others as well that will be sharing the roadway with you.• You must hold a commercial learner’s permit for no less than 14 days. • You must be able to provide a commercial vehicle of the same type in which you plan to test with. • You must take and pass a three-part CDL test which includes vehicle inspection, basic controls test, and a road test. • Additionally, to get a commercial learner’s permit, you will need to obtain a driving record and a medical examination.There are three types of CDL classes that determine the type of vehicle you may drive and how much you may tow. A Class A CDL class allows you to operate a vehicle with a GCWR of 26,001 if the vehicle you tow weighs more than 10,000 and a Class B CDL allows you to operate a vehicle with a GVWR of 26,001 or more pounds or operate any vehicle towing another vehicle that weighs less than 10,000 GVWR.
