Questions (30)
1. If there is a fire on a school bus, the students:
- Must be evacuated. ✓
- Should stay on the bus but be moved to a part of the bus unaffected by the fire.
- Should stay in their seats.
Answer: A. Must be evacuated.
If there is a fire on a school bus, the students must be evacuated. The handbook sets a general rule that student safety and control are best kept by leaving students on the bus during an emergency, but only as long as staying aboard does not put them at unnecessary risk. It then lists the conditions a driver should weigh when deciding whether to evacuate, and the first one is whether there is a fire or danger of fire, or a smell of raw or leaking fuel. A fire is exactly the kind of risk that makes staying on the bus unsafe, so the students need to be gotten off.
2. Doors should be closed while a school bus is being driven, except when:
- Crossing railroad tracks. ✓
- Needing to cool off the inside of the vehicle.
- There is no vehicle next to the bus.
Answer: A. Crossing railroad tracks.
The doors may be open when the school bus is crossing railroad tracks. The handbook's on-road driving section says a bus driver may be required to open the window and door before going over tracks. That is the exception given for having the door open while the bus is moving. The railroad-crossing passages focus on stopping, sight distance, and clearing the tracks; none of them say doors must stay shut at crossings. So the bank answer fits the handbook: crossing tracks is when door use can be required.
3. An empty truck:
- Requires a shorter stopping distance than a full truck.
- Requires a longer stopping distance than a full truck. ✓
- Takes the same distance to stop as a full truck.
Answer: B. Requires a longer stopping distance than a full truck.
4. During the driving test, when encountering a railroad crossing, you should:
- Pass another vehicle on the tracks if the other vehicle is going too slow.
- Get out of the vehicle to check for a train.
- Not change gears while your vehicle is on the tracks. ✓
Answer: C. Not change gears while your vehicle is on the tracks.
You should not change gears while any part of your vehicle is on the tracks. The handbook says that before the crossing you should decelerate, brake smoothly, and shift gears as needed, but once any part of the vehicle is in the crossing you must not stop, change gears, pass another vehicle, or change lanes. Gears are set before you reach the tracks so you can keep both hands on the wheel and drive straight across without interruption. The school bus section repeats the same idea: cross in a low gear and do not shift while crossing.
5. When near a railroad crossing:
- You should expect to hear every approaching train.
- You may not hear a train, even if one is approaching. ✓
- You will hear two short blasts of a train's horn if a train is approaching.
Answer: B. You may not hear a train, even if one is approaching.
You may not hear a train, even if one is approaching, so do not rely on hearing it. The handbook warns that trains may not sound their horns at some crossings, and signs identify public crossings where horns are not used. It also says noise inside your vehicle can keep you from hearing a horn until the train is dangerously close. Since your ears are not a dependable warning, approach crossings expecting a train, stay alert, and look both ways.
6. If approaching a railroad crossing that is being approached by a train, you should:
- Try to cross the tracks quickly.
- Drive around any lowered gates.
- Stop and wait for the train to pass before beginning across the tracks. ✓
Answer: C. Stop and wait for the train to pass before beginning across the tracks.
Stop and wait for the train to pass before you begin crossing the tracks. The handbook says flashing red lights and bells at a crossing mean a train is approaching, and you must stop and yield the right of way. It tells you to remain stopped until the gates go up and the lights stop flashing, then proceed only when it is safe. It also warns against driving around a gate that stays down. Waiting keeps you from starting across while the train is still coming.
7. If a driver needs to exit a school bus to ensure all waiting students have boarded, the driver should:
- Leave the bus running.
- Turn the bus off and take the key. ✓
- Ask a student to keep an eye on the steering wheel.
Answer: B. Turn the bus off and take the key.
The driver should turn the bus off and take the key. The handbook's loading procedure says to turn off the ignition switch and remove the key if you leave the driver's compartment. It gives the same key-removal instruction for unloading. The separate instruction for a student you cannot account for says to secure the bus and take the key before checking around and underneath it. Together, these passages point to shutting the bus down and keeping the key with you when you step outside.
8. When students are being picked up by a school bus:
- The students should wait at a designated bus stop. ✓
- The driver should pick up students whether or not they are at the designated bus stop.
- The parents should choose where the bus stop will be located.
Answer: A. The students should wait at a designated bus stop.
Students should wait at a designated bus stop, facing the bus as it approaches, and board only when the driver signals. The handbook says students are to wait in a set location for the school bus and face it while it approaches, and they board only after the driver signals them. It also tells the driver to stop with the front bumper at least 10 feet from students at the designated stop, which makes the students walk to the bus so the driver can better see their movements. That setup keeps students in one predictable place for loading. So waiting at the designated stop is the correct practice.
9. Interstate carriers must have what information affixed to the commercial motor vehicles in their fleet?
- Trade name ✓
- Width of the truck
- Length of the truck
Answer: A. Trade name
10. As the driver of a truck carrying a load, you are responsible for all of the following, except:
- Inspecting the cargo.
- Recognizing poorly balanced weight.
- Knowing the phone numbers of all fire departments along your intended route of travel. ✓
Answer: C. Knowing the phone numbers of all fire departments along your intended route of travel.
You are not required to know the phone numbers of all fire departments along your route; the cargo duties are inspecting the cargo and recognizing poorly balanced weight. The fire section of the handbook tells you to make a complete inspection of the vehicle, and it lists cargo as something to check, including cargo that is improperly sealed or loaded. Poorly balanced weight is part of judging how a load is loaded, so it belongs with your cargo duties. Nothing in the handbook asks a driver to collect fire department phone numbers for the route. The fire section is about preventing fires and knowing how to use your extinguisher, not about memorizing who to call along the way.
