As a school bus driver in South Dakota, your shift will usually begin early in the morning. You will start by inspecting your school bus to ensure it’s safe and ready for the road. Then you will drive your assigned route, picking up students and dropping them off at school before classes begin. When you’re behind the wheel of a school bus, you must prioritize safety at all times. Even a small mistake can have serious consequences, and that’s why only professional drivers succeed in this field.

The official South Dakota Commercial Driver License Manual (South Dakota CDL Handbook 2025) includes an individual chapter on the safe operations of school buses. Please read its contents several times to learn more about student management, special safety considerations, danger zones, and loading and unloading procedures. Your knowledge of this subject will be tested at a DMV office on the official written knowledge test for the School Bus (S) endorsement.

It is up to date as of September 2025 to reflect the latest changes brought by DMV rules or state law. You get unlimited attempts and nonstop access to train as often as your schedule allows.

The test settings menu includes several features you can use to customize your testing experience. This menu can be accessed by clicking the three dots in the top-right corner of the page. Activate the answer popularity feature to gain helpful insight into the performance of other students. Identify questions where misconceptions are common and ask our automated assistant to explain them to you. This AI coach can also provide real-life examples and hints.
