Questions (16)
1. 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.
Dry bulk tanks usually have high centers of gravity. The handbook's cargo section directly describes dry bulk tanks as needing special care because they have a high center of gravity and the load can shift. That means the weight is carried high, making the vehicle less stable. The same passage tells you to be very cautious, slowing down for curves and sharp turns. The tank vehicle section also explains that a high center of gravity makes a vehicle top-heavy and easier to roll over, which fits the warning given for dry bulk tanks.
3. Trailers with low underneath clearance can present challenges when driving over:
Bridges.
Railroad tracks. ✓
Overpasses.
Answer: B. Railroad tracks.
Trailers with low underneath clearance can get hung up on railroad tracks, so railroad tracks are the hazard named in the question. The handbook warns that railroad tracks can cause problems, especially for a trailer with low underneath clearance, and says not to risk getting stuck halfway across. That directly points to railroad tracks as the place where low clearance matters. The passages do not identify bridges or overpasses as the low-clearance trailer problem.
4. If other vehicles are having a difficult time getting around your truck on a road with two or more lanes, you should:
Speed up.
Drive on the shoulder.
Use the right lane. ✓
Answer: C. Use the right lane.
Use the right lane when other vehicles are having trouble getting around your truck. The handbook says heavy vehicles often get tailgated when they cannot keep up with traffic, especially uphill. It advises staying in the right lane if you can. It also says not to speed up when tailgated and to open space ahead so the driver behind can get around. Using the right lane leaves other lanes free for faster traffic and fits that guidance.
6. When operating a school bus, mirrors should be adjusted:
During the drive.
Before beginning to drive. ✓
After the drive is completed.
Answer: B. Before beginning to drive.
Mirrors should be adjusted before you begin to drive the school bus. The handbook says you should always check each mirror before operating the school bus so you get the maximum viewing area, and have the mirrors adjusted if needed. That places mirror adjustment before the bus starts moving. Checking mirrors later, while driving or after the trip, does not meet the handbook's instruction to check them before operating the bus. The point is to be able to see the danger zone around the bus and look for students, traffic, and other objects.
7. 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.
8. When encountering a railroad crossing during the driving test, you should:
Pass another vehicle on the tracks if the other vehicle is moving too slowly.
Change lanes while on the tracks.
Not change gears while on the tracks. ✓
Answer: C. Not change gears while on the tracks.
You should not change gears while on the railroad tracks. The handbook's on-road driving section says that while any part of your vehicle is on the tracks, you should not stop, shift gears, or switch lanes. It also says to keep your hands on the steering wheel as you cross. The school-bus section gives the same rule in practice: cross in a low gear and leave the gears alone until you are clear. So the action that matches the handbook is to keep the gear you selected and not change it on the tracks.
9. If your vehicle gets stuck on railroad tracks, you should:
Sit in the cab and call for help.
Exit the cab and walk away from the tracks. ✓
Motion for another driver to push your vehicle.
Answer: B. Exit the cab and walk away from the tracks.
Leave the cab and move away from the tracks. The handbook says that if you get stuck on the tracks for any reason, you should get out of the vehicle and away from the tracks. Once clear, check the signposts or signal housing at the crossing for emergency notification information, then call 911 or another emergency number. When you call, give the crossing location using landmarks, especially the DOT number if it is posted. The first action is to get yourself off the tracks, not to stay with the vehicle.
Only use the side mirrors on the passenger's side.
Answer: B. Use both side mirrors.
Use both side mirrors when backing a truck. The handbook lists using mirrors on both sides as one of its basic backing safety rules. It says to check the outside mirrors on both sides often, and to get out and check your path when you are unsure. The passages explain that you cannot see everything behind the vehicle, so you need to watch both sides as you back.
