Visit a convenient DMV office (see link in Resources section), and apply for your learner's permit. You must pass a basic vision and knowledge test. Find a truck driving school and complete your truck driving training for the vehicle for which you wish to qualify. For example, a class B license is required for single vehicles with a gross vehicle weight rating (GVWR) of at least 26,001 lbs. When carrying out your training, you must be accompanied by someone who has held the relevant class of CDL for at least two years and a regular driver's license for five years. Study your state's CDL manual (see link in Resources section) alongside your training before taking the written and practical examinations. If you pass, your CDL will remain valid for five years.
Testing for the CDL breaks down into a written knowledge test and a three-part practical examination. Your state's CDL manual will provide all the information you require for the knowledge test (see link in Resources section), while your truck driving lessons will prepare you for the practical exam. Complete the pre-trip inspection to pass the first part of practical testing, which will require you to show knowledge of the basic mechanical and safety functions of the CMV. Progress to the maneuvers testing, where an examiner will accompany you in the cab as you drive a series of basic maneuvers. Finally, finish the practical exam by completing a real-life road test of your ability to drive on the road in regular traffic.
Passing your CDL qualifies you for most driving jobs. Contact employers and inform them of your training both in commercial driving and other education. Communicate clearly about the class of CDL you hold; for example, employers will be attracted by the fact you have passed your HazMat class H endorsement, which entitles you to drive hazardous goods. Apply for a school bus driving job only if you hold the class S school bus endorsement, which requires additional knowledge and practical testing. Take your CDL and any endorsements along with you to job interviews to show your competence.
Training for your CDL also provides you with a number of transferable skills that will benefit you in other career paths. One closely related field you can enter is the administrative side of commercial driving. Using your truck driving skills and extensive knowledge of the laws and regulations on commercial vehicles, you can also train other CDL applicants; you must have held a regular driver's license for five years and a CDL for two years in the class for which you are training. Any CDL endorsements you hold can also qualify you for opportunities. For example, if you have the class S endorsement, entitling you to drive school buses, you can gain an entry-level position at a local school before working your way up the hierarchy to a more important administrative position.
