Sample Missouri Passenger Test Questions

Question 1

After stopping a bus at a railroad crossing, what may improve your ability to detect an approaching train?

  1. A Move the bus closer to the nearest rail
  2. B Turn on the radio
  3. C Open the forward door
  4. D Turn off all exterior lights

Correct answer: C – Open the forward door

The driver must look and listen in both directions before crossing. Opening the forward door may improve the ability to see or hear an approaching train, particularly where visibility or sound is restricted. Missouri’s CDL manual presents this as an additional observation technique, not as a substitute for stopping in the proper location and checking the tracks.

Question 2

Which item is not required by the federal emergency-equipment rule for a bus?

  1. A A properly rated fire extinguisher
  2. B Required warning devices for a stopped vehicle
  3. C A general repair tool kit
  4. D Secure mounting for the fire extinguisher

Correct answer: C – A general repair tool kit

Federal equipment rules require a bus to carry a properly rated fire extinguisher and approved warning devices for a stopped vehicle. The extinguisher must be charged, accessible, and securely mounted. A general-purpose repair tool kit is not included among the emergency equipment required by this rule.

Question 3

Which conditions must be satisfied before a bus begins moving?

  1. A Any standing riders are behind the standee line
  2. B Aisles and doorways are unobstructed
  3. C Baggage and freight are properly secured
  4. D All of the above

Correct answer: D – All of the above

Standing passengers must remain behind the standee line on a bus designed to carry standees. Carry-on items must not be left in aisles or doorways, and baggage or freight must be secured. Securement must allow the driver to move freely, keep emergency exits available, and protect passengers if items shift or fall.

Question 4

In which direction does a bus tend to lean while traveling through a curve?

  1. A Toward the inside of the curve
  2. B Toward the front of the bus
  3. C Toward the rear of the bus
  4. D Toward the outside of the curve

Correct answer: D – Toward the outside of the curve

A bus tends to lean toward the outside of a curve. Because buses have relatively high centers of gravity, excessive curve speed can contribute to a rollover when traction is good or a slide when traction is poor. Missouri’s CDL manual warns that noticeable outward leaning on a banked curve indicates the bus is traveling too fast.

Question 5

Which emergency-exit condition must be corrected before a bus is driven?

  1. A An emergency exit door or window is open
  2. B The emergency-exit handles operate properly
  3. C The emergency-exit sign is clearly visible
  4. D The exit warning devices are working

Correct answer: A – An emergency exit door or window is open

Open emergency exits must be closed before driving, and a bus must never be operated with an emergency exit door or window open. During inspection, the driver should also confirm that exits are undamaged, operate smoothly, and close securely. Required signs, handles, lights, and warning devices must be in working condition.

Source: Missouri Commercial Driver License Manual — § 4.1.2, “Access Doors and Panels”; § 4.1.3, “Bus Interior”

Question 6

When may an aisle seat be installed in a bus?

  1. A When it automatically folds and leaves the aisle clear while unoccupied
  2. B Whenever the bus has no more than two aisle seats
  3. C Only when the bus is used for charter service
  4. D Never under any circumstances

Correct answer: A – When it automatically folds and leaves the aisle clear while unoccupied

Federal rules generally prohibit aisle seats unless they are designed and installed to fold automatically and leave a clear aisle when unoccupied. The regulation does not establish a fixed allowance of two, four, or another number of folding seats. Every seat must also be securely fastened to the vehicle before the bus is operated.
