Every school morning across Alaska, families trust a school bus driver to transport their children safely. Because this responsibility is so critical, federal requirements must be met, and the Alaska DMV requires every applicant seeking a School Bus “S” Endorsement to pass the official CDL School Bus Knowledge Test. Drivers must pass a skills test in a school bus. In addition to federal and state requirements, applicants must also satisfy any local or district expectations. These can often vary, so be sure to check with your local authority.
The School Bus Knowledge Test places its strongest emphasis on safe loading and unloading, with “danger zones” around the bus being specifically highlighted as where most injuries occur. You are expected to understand how to monitor children as they approach the bus on icy ground, how to maintain complete visibility of blind spots, and how to prevent students from slipping, falling, or getting caught on handrails during entry or exit. The official state CDL manual also covers the importance of controlled stopping on surfaces ranging from hard-packed snow to gravel roads. Also, it’s important to note that drivers holding a commercial learner’s permit (CLP) with a Passenger or School Bus endorsement are prohibited from transporting passengers of any kind until fully licensed.

Railroad crossings are another important topic on the knowledge test. You must also know how to bring a school bus to a safe, complete stop, account for limited sightlines, and make evacuation decisions as needed (and in consideration of when temperatures or terrain pose additional risk). There are also student-behavior-management expectations, emergency response procedures, and mandatory post-trip walkthroughs and inspections to ensure no child is left behind and there has been no damage to the vehicle.
Our Alaska School Bus “S” Endorsement Practice Tests eliminate guesswork and mirror the structure of the official exam. Our experts have eliminated unnecessary information, focusing on only what you’ll need to pass the official exam. Each practice test features AI-driven feedback, an interactive CDL manual, and a state-of-the-art Challenge Bank that returns to missed questions until you consistently answer them correctly. Additionally, your performance breakdown at the end highlights where to focus next. Once you’ve mastered this practice test, try another one here: https://driving-tests.org/alaska/ak-cdl-school-bus-practice-test/.
You’ll also need to pass the Passenger “P” Endorsement Knowledge Test required for all school bus operators. Our Passenger Vehicles Practice Tests provide the same structured approach: https://driving-tests.org/alaska/ak-cdl-passenger-vehicles-practice-test/. Since most large school buses are air-brake equipped, you may want to prepare for the Air Brakes Knowledge Test to ensure you meet these requirements: https://driving-tests.org/alaska/ak-cdl-air-brake-practice-test/.
