Would you like to land yourself a job driving medium-sized commercial vehicles like small school buses or regular box-trucks? If the answer is “yes”, you’re going to need to pass the Class B test for South Dakota. Class B is the “middle-ground” commercial driving license, being more advanced that Class C but not as advanced as Class A. Unless you see yourself driving huge commercial vehicles cross-country, you will likely find that the Class B DMV test for South Dakota is more than sufficient for your needs. As an added bonus, passing the SD DMV test for a Class B commercial driving license will automatically qualify you to operate any smaller vehicles which come under Class C, as Class B vehicles are more challenging to drive.

As you are probably aware, there are other theory exams associated with the commercial driving licenses. These are the endorsement tests. Once you have your main license, you can apply for further “add-ons” in the form of endorsements, which evidence any vehicle or occupation-specific knowledge you may have.

Most commercial driving roles have one or more endorsements associated with them. Depending on the class of vehicle you hope to drive, you might find some of these tests are mandatory. For instance, becoming a Class B commercial driver would require you to sit the Air Brake endorsement exam at a minimum, as air brakes are a common feature among vehicles in this class. You might then wish to obtain further endorsements, based on your chosen career path. Aspiring school bus drivers would need to obtain a School Bus endorsement, while transporting any hazardous materials would require a HazMat endorsement. There are no DMV test questions on this SD CDL general knowledge practice test for the endorsements; however, we do have other endorsement-specific CDL practice tests on this website you can use when you’re ready.
