Before you may take the skills test for a commercial driver’s license (CDL), you must obtain a commercial learner’s permit (CLP) and hold it for at least two weeks. Your CLP will allow you to practice operating commercial motor vehicles (CMVs) while supervised by a licensed commercial driver qualified to operate that type of vehicle. In North Carolina, you must be 18 years old for a CLP. A key requirement for a CLP is to pass a set of official knowledge tests for the class and the type of vehicles you plan to drive. But no matter which vehicles you plan to drive, you must at least pass the General Knowledge test, which covers general commercial driving theory.
The official General Knowledge test covers many commercial driving topics, including pre-trip and other vehicle inspections. Your test will likely include questions on which systems or components you should check during a pre-trip inspection and how to determine whether they are performing adequately. All questions on the General Knowledge test are based on the official North Carolina CDL manual (North Carolina CDL Handbook 2025). You should study the manual. However, if all that complex information leaves you wishing for additional help to pass the General Knowledge test – well, that’s what we’re here for!

In North Carolina, rapid growth, especially in cities like Charlotte, has increased traffic congestion, which has led to more traffic accidents. Two of the most dangerous stretches of road are in Charlotte: I-77 and I-85. I-77 has seen numerous accidents involving semi-trucks and other large vehicles. I-95 is also considered hazardous because of heavy congestion and aging or obsolete infrastructure. However, a thorough pre-trip inspection of your vehicle will help ensure it’s ready to tackle even hazardous roads safely.
