CA CDL School Bus Practice Test 2 2025

To drive California school buses,California requires all applicants to pass the California CDL DMV School Bus “S” Endorsement Knowledge Test. Additionally, to transport students, you’ll need to obtain the Passenger “P” endorsement and satisfy all other federal, state, and district requirements. Many school districts also add their own safety, training, or evaluation requirements, so check with your local authority. The topics covered on the knowledge test are extensive, but rest assured that our California CDL School Bus “S” Endorsement Practice Tests are designed to ensure you pass on your first attempt.

The California School Bus Knowledge Test focuses largely on loading and unloading procedures, because this is where most injuries occur. The manual defines “danger zones” as extending up to thirty feet in front of the bus (the first twelve feet are labeled the most hazardous), and twelve feet along each side and behind the vehicle. Understanding these zones and knowing how to monitor them through constant mirror use (and proper mirror adjustment to cover blind spots) is a key concern and will certainly be covered on your test.

Most student fatalities happen while they are getting on or off the bus, so California’s rules surrounding stops, hazard scanning, and handrail checks are paramount. Drivers are also expected to watch until every child reaches a safe point away from the vehicle before moving the bus again. When routes are complete, the state requires a post-trip walkthrough to check for sleeping children, left-behind items, and any mechanical concerns or vandalism. All of these topics and more are potentially tested on the official exam and covered on our California CDL School Bus “S” Endorsement Practice Tests.

Our California School Bus “S” Endorsement Practice Tests are modeled after the official exam structure. We also provide AI-driven feedback, an interactive CDL Manual, and our state-of-the-art Challenge Bank of questions that remembers any missed questions and presents them again until you’ve mastered them. These features help ensure you are ready to pass your official exam on the first attempt.
