Commercial drivers can do much more with their CDL license by applying for endorsements. As with regular driver licenses, CDLs offer a range of classes and endorsements that can increase your employment opportunities, although different CDL classes and endorsements typically come at a cost. The CDL HAZMAT endorsement is one of the most sought-after endorsements that can come with a broader range of employment opportunities with greater compensation.
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. With a Class C CDL, you can operate a Class C vehicle that transports hazardous materials.
