What are the requirements for getting a commercial driver's license?

To obtain a commercial driver's license (CDL) in Pennsylvania, there are certain requirements you must meet. Firstly, you need to be at least 18 years old for intrastate driving and 21 years old for interstate driving. Next, you must possess a valid non-commercial driver's license and have a clean driving record. A medical examination, performed by a certified healthcare professional, is also mandatory to ensure you meet the physical qualifications. Additionally, you must obtain a learner's permit and pass a written knowledge test specific to the type of CDL you are pursuing. After successful completion of the knowledge test, a skills test including a pre-trip vehicle inspection, basic vehicle control, and an on-road driving examination should be passed. Finally, pay the necessary fees and provide proper identification to receive your CDL.
