1. 1. Loading & Passengers

   Which of the following hazardous materials is a bus permitted to carry?

   • a.A large quantity of explosives in the passenger compartment
   • b.Any amount of Division 2.3 poison gas
   • c.Small-arms ammunition labeled ORM-D
   • d.Tear gas devices

   Respuesta: c

   Explicación: Buses may carry small-arms ammunition labeled ORM-D, emergency shipments of drugs or hospital supplies, and small amounts of some other hazardous materials. Buses are prohibited from carrying explosives, poison gas, tear gas, and most other hazardous materials. Never carry hazardous materials unless you are sure the rules allow it.

2. 2. Loading & Passengers

   When passengers are getting on and off the bus at a stop, you should:

   • a.Watch them closely and be alert for slips, trips, or riders reaching under the bus
   • b.Read your route schedule
   • c.Rev the engine to hurry them
   • d.Close the door on the last person to save time

   Respuesta: a

   Explicación: Watch riders as they get on and off to prevent falls and injuries. Be especially alert for children or elderly riders who move slowly. Never close the doors or start moving until everyone is safely clear of the doorway and the bus.

3. 3. Loading & Passengers

   Passengers should be discouraged from standing near the front doorway while the bus is moving because:

   • a.It is more comfortable to sit in back
   • b.They can fall out or interfere with the driver in a sudden stop
   • c.The heater is stronger there
   • d.It slows the bus down

   Respuesta: b

   Explicación: A rider standing at the front door can be thrown against the door or out of the bus in a sudden stop or crash. They can also block the driver's view and controls. Keep standees behind the standee line and away from the door.

4. 4. Loading & Passengers

   A driver who must eject a disruptive passenger should:

   • a.Do it while the bus is still moving
   • b.Choose a safe location and stay calm and professional
   • c.Push the rider off at a freeway ramp
   • d.Leave them at an unlit rural stop

   Respuesta: b

   Explicación: Removing a disruptive rider must be done safely and professionally. Stop at a safe, well-lit place such as a scheduled stop, not a dangerous or isolated spot. Staying calm reduces the chance the situation gets worse for you and other riders.

5. 5. Inspection

   If you find a problem with an emergency exit during your pre-trip inspection, you should:

   • a.Not drive the bus with passengers until it is fixed
   • b.Drive anyway and report it later
   • c.Tape the exit shut and continue
   • d.Only fix it if inspectors are present

   Respuesta: a

   Explicación: You must never drive a bus with an unsafe emergency exit or other safety defect. Have the problem repaired before carrying passengers. Riders' lives may depend on that exit working during a fire or crash.

6. 6. Inspection

   Signaling devices that let passengers request a stop should be checked to be sure they:

   • a.Work so riders can signal the driver to stop
   • b.Are painted yellow
   • c.Play music
   • d.Are disconnected

   Respuesta: a

   Explicación: Many transit buses have cords, buttons, or strips that riders use to signal for a stop. These must work so passengers can tell the driver where they need to get off. Test them during your interior inspection along with other safety devices.

7. 7. Inspection

   Which statement about bus pre-trip inspections is TRUE?

   • a.A bus must never be driven with an unsafe defect that endangers passengers
   • b.Interior items do not need inspection
   • c.Only the engine matters
   • d.Inspection is optional if you are running late

   Respuesta: a

   Explicación: You must never drive a bus with a safety defect that could endanger passengers, such as bad brakes, a broken exit, or unsafe tires. The pre-trip inspection covers both the vehicle systems and passenger-specific items. A running-late schedule never justifies skipping the inspection.

8. 8. Safe Driving

   A bus should not begin to cross railroad tracks unless:

   • a.The signal is red
   • b.There is enough room to completely clear the tracks without stopping
   • c.A police officer is present
   • d.Another bus goes first

   Respuesta: b

   Explicación: Never start across the tracks unless you are sure you can get completely across without stopping. Leave room on the far side for the entire bus before you begin. Stopping on the tracks with passengers aboard is extremely dangerous.

9. 9. Safe Driving

   Speed on a downgrade with a loaded bus should be controlled by:

   • a.Riding the service brakes the whole way
   • b.Shifting to neutral to coast
   • c.Selecting a low gear and using proper braking technique before the grade
   • d.Speeding up to get it over with

   Respuesta: c

   Explicación: Before starting down a long, steep grade, shift to a low gear and keep your speed in check so the brakes do not overheat. Continuous braking can cause brakes to fade and fail. A heavy, loaded bus needs extra care on downgrades.

10. 10. Safe Driving

    A bus with standing passengers should be driven so that the driver:

    • a.Accelerates and brakes sharply
    • b.Takes curves fast
    • c.Avoids sudden stops, starts, and turns that could throw standees
    • d.Ignores the standees

    Respuesta: c

    Explicación: Standing riders can be thrown down by sudden acceleration, braking, or sharp turns. Drive smoothly and look far ahead so you can make gradual speed and direction changes. Smooth driving is the best way to protect standees.
