A school bus driver should know to never:
Correct answer: A. Use a handheld phone or text while driving
Why: Federal and state law prohibit handheld phone use and texting in CMVs. With students aboard the consequences are heightened.
Most fatal school bus incidents happen outside the bus, in the danger zones around it. This endorsement exists to make sure every driver can predict the behavior of children entering and exiting the loading zone.
Know the dimensions of the front, side, and rear danger zones, the proper eight-light activation sequence, and the emergency evacuation procedure including front-door, rear-door, and split evacuations.
The School Bus portion of the CDL knowledge exam covers more than this single question. Use this site's full School Bus bank to drill every topic, then test yourself with one of our state-specific practice sets to confirm you are ready for the actual DMV exam in your state. Always check your state's CDL handbook for any local addenda before the test day.
If you are still building your overall CDL foundation, start with the General Knowledge bank — every CDL applicant must pass it — and then work outward to the endorsements you plan to add.
