Q11During pre-trip inspection you find that the emergency roof hatches on the bus do not latch shut — they flutter slightly when you push them. Which of the following best describes the correct action and the regulatory reason?
✓ Correct answer: A. Place the bus out of service; roof hatches are required emergency exits that must both open readily and latch securely when closed
The FMCSA CDL manual classifies roof hatches as emergency exits; they must open readily for evacuation AND latch securely when closed to maintain structural integrity and prevent inflight opening, so a hatch that will not latch is a defect that takes the bus out of service.
Q12You are inspecting a bus that will cross an active drawbridge today. Which statement about drawbridge procedures is CORRECT per the CDL manual?
✓ Correct answer: B. Buses must stop before a drawbridge unless there is a traffic control signal showing green AND the bridge is not the type that must always be stopped at
The CDL manual specifies that a bus must stop before a drawbridge unless a traffic-control signal is green AND the bridge is not designated as one requiring a mandatory stop; simply having no flashing lights is not sufficient to waive the stop requirement.
Q13A school bus driver completes a route and parks the bus. During the required post-trip inspection walk-through, the driver finds a student's backpack but no child. What does the CDL manual require the driver to do next?
✓ Correct answer: A. Search the entire bus thoroughly — including under seats and in any storage areas — to confirm no child is concealed or unconscious on board before securing the vehicle
The CDL manual's post-trip inspection requirement for school buses mandates a complete interior walk-through to every corner of the bus, including under seats and storage areas, to ensure no child is left behind before the vehicle is secured.
Q14What is the purpose of the standee line on a bus?
✓ Correct answer: B. It marks the boundary behind which standing passengers must remain
The standee line is a marked line two feet behind the driver's seat, and no standing passenger is permitted to stand forward of it while the bus is in motion.
Q15Which of the following is true regarding standing passengers on a bus?
✓ Correct answer: B. No passenger may stand forward of the standee line while the bus is moving
Federal regulations require that no passenger stand forward of the standee line, which is located two feet behind and parallel to the driver's seat.
Q16Which type of cargo is generally prohibited from being carried in the passenger compartment of a bus?
✓ Correct answer: B. Hazardous materials
The FMCSA CDL manual states that buses must not carry hazardous materials in the passenger space, with only narrow exceptions for small quantities of certain items.
Q17Where must baggage and cargo be stowed on a bus to comply with safety regulations?
✓ Correct answer: C. In a location where it will not block exits or fall on passengers
CDL regulations require that all baggage and cargo be secured so it does not block emergency exits, the aisle, or the driver's view, and will not shift and injure passengers.
Q18A passenger wants to board your bus carrying a small container of gasoline for a lawn mower. What should you do?
✓ Correct answer: A. Refuse to allow it because flammable liquids are prohibited in the passenger space
Flammable liquids such as gasoline are classified as hazardous materials and are prohibited from the passenger compartment of a bus under FMCSA regulations.
Q19Which of the following hazardous materials categories is permitted in small amounts inside the passenger space of a bus?
✓ Correct answer: A. Small-arms ammunition, toiletry articles, and medical supplies carried by passengers for personal use
The CDL manual identifies narrow exceptions that allow passengers to carry certain items such as small-arms ammunition, personal-use toiletries, and medical supplies in limited quantities inside the bus.
Q20Before beginning a trip, you notice that a large suitcase has been placed in the aisle halfway between the front and rear doors. What is the correct action?
✓ Correct answer: A. Move or have it moved so the aisle and exits remain unobstructed
Federal regulations require that baggage and cargo not obstruct the aisle or any emergency exit, so the suitcase must be properly stowed before the trip can begin.
