1. 1. Loading & Unloading

   What is the 'danger zone' around a school bus?

   • a.The interior aisle where students stand while boarding
   • b.The 50-foot lane reserved for the bus at the curb
   • c.Only the space directly behind the rear bumper
   • d.The area on all sides of the bus where children are in the most danger of being hit

   Đáp án: d

   Giải thích: The danger zone is the area on all sides of the bus, extending as much as 30 feet from the front bumper and 10 feet on the other sides, where children are at the greatest risk of being struck. A driver may not be able to see students who are within this zone. Extra caution and mirror checks are essential before moving.

2. 2. Loading & Unloading

   If a student drops something near the bus while crossing, you should teach them to:

   • a.Crawl under the bus to retrieve it
   • b.Kick it out of the way toward the curb
   • c.Quickly grab it before traffic comes
   • d.Leave it and tell the driver, never bend down to pick it up

   Đáp án: d

   Giải thích: Students should be taught never to stop to pick up a dropped object near the bus, because bending down puts them in the driver's blind spot. Instead they should tell the driver, who can keep them in view or retrieve it safely. Reaching under or near the bus is extremely dangerous.

3. 3. Loading & Unloading

   When a student is approaching the bus at the stop and is late, you should:

   • a.Keep the bus secured and never move until the student is seated and accounted for
   • b.Close the door and leave to stay on schedule
   • c.Slowly roll forward to encourage them to hurry
   • d.Wave them across from behind the bus

   Đáp án: a

   Giải thích: Never move the bus toward or past a late-arriving student; keep it fully secured until they are safely aboard and seated. Rolling forward can pull a running child under the wheels. Staying on schedule is never worth a student's safety.

4. 4. Railroad & Special

   At a railroad crossing, a school bus must:

   • a.Stop only when carrying students
   • b.Stop, whether or not it is carrying passengers, unless the crossing is exempt
   • c.Slow down but may roll through if no train is visible
   • d.Never stop, to avoid stalling on the tracks

   Đáp án: b

   Giải thích: School buses are required to stop at railroad crossings whether or not students are aboard, except at crossings marked exempt or where a police officer or signal directs otherwise. The driver stops, looks, and listens before proceeding. This rule exists because of the catastrophic consequences of a train collision.

5. 5. Railroad & Special

   When you move toward the oncoming train to evacuate, you angle away from the tracks because:

   • a.Debris from the collision will fly forward, away from the train's direction of travel
   • b.The train crew can see you better
   • c.It is the shortest path to the road
   • d.Trains stop quickly

   Đáp án: a

   Giải thích: You move toward the train but at an angle away from the tracks so that when the train strikes the bus, the debris is thrown forward in the train's direction of travel, away from you. Running away from the train in the same direction it moves would put you in the path of scattering wreckage. This roughly 45-degree angle toward the train is the standard escape direction.

6. 6. Railroad & Special

   After the bus has safely crossed the tracks, the driver should:

   • a.Stop just past the rails to check students
   • b.Turn on the red loading lights
   • c.Continue smoothly and get fully clear of the crossing
   • d.Reverse to confirm the tracks are clear

   Đáp án: c

   Giải thích: Once across, keep moving to get the entire bus completely clear of the crossing and out of any second track's path. Do not stop immediately past the tracks where the rear of the bus could still be in danger. Then resume normal driving.

7. 7. Emergency Evacuation

   Appointing student helpers before an emergency is useful because:

   • a.Trained older students can help open exits and lead others to safety
   • b.It replaces the need for the driver to act
   • c.It lets the driver leave the scene
   • d.It reduces fuel use

   Đáp án: a

   Giải thích: Assigning and training responsible older students to help operate emergency exits and lead classmates to the safe area speeds an orderly evacuation. The driver cannot be everywhere at once. Practiced helpers reduce panic and help account for younger children.

8. 8. Emergency Evacuation

   The driver should carry the student roster during an evacuation so that:

   • a.It can be handed to the next driver
   • b.It proves the route was completed
   • c.Every student can be accounted for after leaving the bus
   • d.It can be used as a fan

   Đáp án: c

   Giải thích: Taking the passenger roster or count during evacuation lets the driver confirm that every student who was aboard is present and safe at the assembly point. A missing name signals someone may still be near or on the bus. Accounting for all students is a critical post-evacuation step.

9. 9. Safe Driving

   The safest way to handle any backing situation in a school bus is to:

   • a.Back quickly to get it over with
   • b.Avoid backing whenever possible, and if you must, use a lookout and go slowly
   • c.Rely only on the mirrors
   • d.Back without stopping

   Đáp án: b

   Giải thích: Backing a school bus is dangerous because of large blind spots, so it should be avoided whenever possible. When unavoidable, back slowly, use all mirrors, and use a trained lookout or ground guide to watch the rear and sides. Never back where students are present unless absolutely necessary and fully supervised.

10. 10. Safe Driving

    When making a left turn, you should:

    • a.Reach the center of the intersection before starting the turn to keep the rear from cutting the corner
    • b.Turn from the right lane
    • c.Cut the corner tightly to save time
    • d.Start turning as soon as you enter the intersection

    Đáp án: a

    Giải thích: In a left turn, move to the center of the intersection before turning so the rear wheels, which off-track, do not cut across into oncoming lanes or over the corner. Starting the turn too early can put the rear of the bus into the path of oncoming or crossing traffic. Take left turns wide and controlled.
