AZ CDL School Bus Practice Test 2 2026

You’ve come to the right place to prepare for the Arizona MVD CDL School Bus “S” Endorsement Knowledge Test. Both federal and state regulations require school bus drivers to pass the official knowledge test, followed by a skills test in a school bus. Arizona also requires the Passenger “P” Endorsement for school bus drivers. Additionally, the state requires all school bus drivers to hold a valid Fingerprint Clearance Card issued by the MVD, and every applicant must undergo a background check as part of the bus driver certification process. Note that Arizona issues a “No Passengers in CMV Bus” restriction on Commercial Learner’s Permits (CLPs) with an “S” or “P” endorsement. Therefore, you may only operate empty buses (except, of course, for your driving instructor or driving examiner) until fully licensed. Keep in mind that Arizona school districts may also have additional requirements, such as local safety training, student-management preparation, or district-run driving evaluations.

The School Bus “S” Knowledge Test centers on the safety of children within the bus’s “danger zones.” The CDL manual explains that danger zones can stretch up to 30 feet on all sides of the bus (the first 10 feet being the most hazardous). Because these areas are where most school bus-related injuries occur, you will need to be situationally aware of students, ensuring they are visible, protected, and clear of blind spots. The official test often includes particular attention to mirror use and adjustments. You will also be expected to demonstrate a full understanding of loading and unloading procedures, secure stopping, safe student approach and departure, and constant mirror checks. That’s quite a bit of material and exactly why our experts have crafted a series of Arizona CDL School Bus “S” Endorsement Practice Tests that help ensure you pass the official knowledge test on your first attempt.
