About the CDL Passenger Endorsement Test
The Passenger endorsement is required for any vehicle built to carry 16 or more people, including the driver. The test reaches beyond ordinary driving into the responsibilities of moving people safely: a pre-trip inspection that includes emergency exits and signaling devices, railroad-crossing procedures, the rule against standees ahead of the standee line, and managing a full load without distraction. Smooth starts, stops, and turns aren't just about comfort here - they keep standing and seated passengers safe.
What's on the CDL Passenger Endorsement knowledge test
The Passenger Endorsement knowledge test is written from Section 4 (Transporting Passengers Safely) of the national CDL manual, the text every state's CDL manual follows. You take it only if you need the P endorsement or drive a vehicle that requires it.
Federal rules fix the pass mark at 80 percent for every CDL knowledge test, but leave the number of questions to each state, so check your own state's CDL manual for the exact count. This practice test uses all 15 questions in our Passenger Endorsement bank, each checked against the manual page shown with it.
- Number of questions
- Set by each state: federal rules require a set number of questions, with a prescribed number from each knowledge area (49 CFR 383.133)
Manual sections this test is drawn from
- Section 4: Transporting Passengers Safely - Vehicle Inspection, Loading and Trip Start, On the Road, After-trip Vehicle Inspection, Prohibited Practices, Use of Brake-door Interlocks
Sample questions from this test, with answers

1. Why must a bus driver be careful about the posted speed on a curve?
- A. Buses may legally go 10 mph over it
- B. It may be too fast for many buses (correct)
- C. It is set for fully loaded trucks
- D. It applies only in rain or snow
Why: In good weather the posted curve speed is safe for cars but may be too high for many buses. With good traction a bus may roll over, and with poor traction it may slide off; if the bus leans outward, you are going too fast.

2. Which statement about hazardous materials on a bus is correct?
- A. Any hazmat may ride along as long as it is labeled
- B. Most hazardous materials cannot go on a bus (correct)
- C. Only explosives are banned on buses
- D. Riders may carry on small gas cans
Why: Most hazardous materials are not allowed on a bus. Allowed items include ORM-D labeled small-arms ammunition, emergency hospital supplies, and drugs, but riders must not bring hazards such as car batteries or gasoline.

3. During an after-trip inspection of a bus, what should you look for and report?
- A. Rider damage to seats, handholds, and exits (correct)
- B. Only the fuel level, so the next driver knows to refuel
- C. Only defects that stopped this trip
- D. Nothing, as long as no rider complained
Why: Inspect the bus at the end of each shift. Riders sometimes damage handholds, seats, emergency exits, and windows, and reporting it lets mechanics fix it before the bus goes out again.

4. Where should you discharge a drunk or disruptive rider?
- A. Right away, wherever the problem starts
- B. On the highway shoulder, safely out of the traffic lanes
- C. At a safe place, such as the next scheduled stop (correct)
- D. At the darkest stop so others don't see
Why: You must protect the disruptive rider's safety as well as everyone else's. Do not put them off where it would be unsafe; the next scheduled stop or a well-lit area with other people may be safer.

5. What is the standee line on a bus?
- A. A floor line riders may not stand in front of (correct)
- B. The line where riders wait outside before they board
- C. A painted stop line at railroad crossings
- D. A line marking reserved seats for elderly
Why: Riders may not stand ahead of the back of the driver's seat. Buses that allow standing have a two-inch floor line or other marker showing where riders cannot stand, and all standees must stay behind it.

6. Can a disabled bus be towed or pushed while riders are on board?
- A. Yes, at any time if you go slowly
- B. Yes, but only on a divided highway
- C. Never, under any circumstances
- D. Only if getting off would be unsafe (correct)
Why: A disabled bus should not be towed or pushed with riders on board unless getting off would be unsafe. Then move it only to the nearest safe spot to let passengers off, following your employer's guidelines.
