Passenger Transport Practice Test
The P endorsement is required for any commercial vehicle designed to transport 16 or more passengers, including the driver. The exam covers vehicle inspection, loading and unloading, standee rules, prohibited hazardous materials on buses, railroad crossings, defensive driving with passengers aboard, after-trip inspection (including the requirement to walk the aisle), driver wellness, and emergency procedures. Drivers must also pass a behind-the-wheel skills test in a representative bus.
How to use this practice bank
Read each question carefully before checking the answer. Most CDL questions are not designed to trick you, but they do test whether you know the specific rule — not just what feels safe. After reading the explanation, try to restate the rule in your own words; if you can, you've internalized it. If you can't, look up the corresponding chapter of your state's CDL handbook before moving on.
Pass scores vary slightly by state, but most jurisdictions require at least 80% correct on each knowledge exam. With 40 questions in this bank you have substantially more practice material than any single sitting of the real exam, which typically contains 20 to 50 questions per endorsement.

About the Passenger Transport exam
The Passenger Transport knowledge test is a multiple-choice exam administered at every state CDL testing site. The questions on this page are seeded from the AAMVA Commercial Driver License Manual — the same source that state agencies use when writing their official questions — and from the corresponding sections of Title 49 of the Code of Federal Regulations. Real test questions are randomly selected from a much larger pool, so practice covers the rules and concepts rather than the wording of any one item.
The most efficient way to study is to work through this bank twice. The first pass identifies the rules you do not yet know; the second pass confirms recall. Drivers who have studied for years rarely miss a question, but newcomers should expect to need a week or more of repeated reading and quizzing before sitting the real exam. Combine this site with your state's printed CDL handbook for the most complete preparation.
