SD CDL School Bus Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Preparing for the School Bus portion of the SD DMV CDL skills test can be overwhelming. You know you have to ace it to drive a school bus in South Dakota, so your entire livelihood depends on it. You have studied the South Dakota CDL manual cover to cover again, but you need to put your skills to the test to see if you have what it takes to pass. You can do just that with the SD CDL School Bus Practice Test. With questions pulled straight from the most recent South Dakota CDL manual, this practice test has the same type of questions that you’ll find on the official test at the DMV.

Gauge Your Knowledge

Begin by using the CDL School Bus Practice Test to determine what you already know. The 20-question multiple-choice test gives you the option of skipping questions that you don’t know. Skip all of the questions that you don’t know, making a note of the ones that you skip. This will allow you to assess your starting point. Then, you’ll know how much reviewing you need to do before you go to the DMV to take your test.

After you have your starting point, hit the books once again. Study up, and once you think you have learned some additional information, take the practice test once again. Skip the questions that you are unsure of again and then get your score. Continue to do this until you are comfortable with all the questions on the test.

How the Practice Test is Scored

Along with providing questions, the South Dakota CDL School Bus Practice Test is scored the same way as the official exam is. You can find out if you would pass the official test when you sit for the practice test.

It’s time to see how prepared you are for the official test. Find out if you’re ready to go to the DMV and get your endorsement. It all starts with the practice test.
