Preparing for the CDL Knowledge Test

An individual seeking to obtain a commercial driver’s license must first take and pass all required knowledge tests. For Class A CDLs, the required tests include general commercial knowledge, combination, and airbrakes. There are also various knowledge tests that must be passed in order to obtain certain endorsements, such as School Bus (S) or Hazardous Material (H). To prepare yourself for these important knowledge tests, study the state’s commercial driver handbook and take CDL practice tests to see where you’re at and what you need to focus on before the actual test.

At Elite Truck School, we will teach you everything you need to know to pass the CDL knowledge test. In addition to in-class and hands-on training, we also provide CDL practice tests to give our students the best chance of obtaining a CDL.
