How this topic appears on the test
The Passenger Transport CDL exam covers Bus operation as a recurring theme. Test-writers favor questions that probe whether the applicant has internalized the safe operating procedure, not merely memorized the rule. When you encounter a question on this topic, slow down and verify that the answer you've chosen describes what a careful, defensive driver would actually do — not what is technically permissible.
If you missed this question, that's exactly the right outcome of a practice session: the goal is to surface gaps before the actual test. Open your state CDL manual to the Bus operation section and re-read the relevant subchapter. Then come back and run through the rest of the Passenger Transport practice exam.
