Questions (13)
1. If you are taking the driving test and the route does not include a railroad crossing, you:
- Will not have to do anything related to a crossing.
- May have to explain how you would cross railroad tracks. ✓
- Will have to take a different route.
Answer: B. May have to explain how you would cross railroad tracks.
If your road test route has no railroad crossing, you may still be asked to explain and demonstrate the proper crossing procedures at a simulated location. The handbook states that not every road test route includes a railroad crossing, and that the examiner may ask you to explain and demonstrate proper railroad crossing procedures at a simulated location. So the crossing requirement does not disappear just because the route lacks real tracks; the examiner can still test your knowledge of the procedures. The safest preparation is to know the crossing steps well enough to describe and show them anywhere.
2. Vehicles driving behind a truck:
- May have difficulty seeing objects in front of the truck. ✓
- Often have a great view of the roadway in front of them.
- Do not need to signal.
Answer: A. May have difficulty seeing objects in front of the truck.
3. When backing a truck, you should:
- Only use the side mirrors on the driver’s side.
- Use both side mirrors. ✓
- 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.
4. When approaching a railroad crossing while transporting chlorine:
- You must stop before crossing the tracks. ✓
- You must reduce your speed before crossing the tracks.
- You may proceed across the tracks without stopping if no warning lights are flashing.
Answer: A. You must stop before crossing the tracks.
When you are hauling chlorine, you must stop before the railroad tracks. The handbook says to stop before a railroad crossing if your vehicle carries any amount of chlorine. It also says to stop 15 to 50 feet before the nearest rail, then cross only when you are sure no train is coming and you can clear the tracks without stopping. The handbook's stop requirement is based on carrying chlorine, so slowing down or rolling across when no warning lights are flashing does not meet the rule.
5. Dry bulk tanks:
- Cannot be driven on interstates.
- Take special care to be driven. ✓
- Are usually not allowed to cross railroad tracks.
Answer: B. Take special care to be driven.
Dry bulk tanks take special care to be driven because of their high center of gravity and the way the load can shift. The handbook says dry bulk tanks need special care for two reasons: they sit high, so the center of gravity is high, and the load inside can shift. That combination makes the vehicle less steady, so you should slow down and be careful on curves and sharp turns. The other choices describe restrictions the handbook never mentions for these vehicles.
6. 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.
7. If backing a truck:
- You should rely on your mirrors to guide you.
- You should first walk the area to become more familiar with obstacles. ✓
- You should look straight ahead.
Answer: B. You should first walk the area to become more familiar with obstacles.
8. Dry bulk tanks:
- Usually have a low center of gravity.
- Usually have a high center of gravity. ✓
- Are usually not allowed to cross railroad tracks.
Answer: B. Usually have a high center of gravity.
Dry bulk tanks usually have a high center of gravity. The handbook section on cargo needing special attention says dry bulk tanks require extra care because their center of gravity is high and the load can shift. That high, shifting weight makes the vehicle less stable, so the handbook says to be very cautious and go slowly around curves and sharp turns. The answer follows directly from that warning: dry bulk tanks usually have a high center of gravity.
9. When driving a truck requiring a CDL:
- You do not need to wear a seat belt.
- You are required to wear a seat belt, but only if transporting more than 500 pounds of cargo.
- You must always wear a seat belt. ✓
Answer: C. You must always wear a seat belt.
You must always wear a seat belt when driving a truck that requires a CDL. The handbook's introduction section says a driver must be properly restrained by a safety belt at all times while operating a commercial motor vehicle. It explains that the belt holds you securely behind the wheel in a crash, which helps you keep control and lowers the chance of serious injury or death, and that an unbelted driver is four times more likely to be killed if thrown from the vehicle. Nothing in that rule depends on what the truck is hauling, so it covers every trip.
10. Who is responsible for cargo that has been loaded onto a truck?
- The person who loaded the truck
- The supervisor of the company
- The truck driver ✓
Answer: C. The truck driver
The truck driver is responsible for cargo loaded onto the truck. The handbook puts the cargo-securement inspection on the person driving the truck. It says drivers transporting cargo must check the securement within the first 50 miles and then every 150 miles or three hours, whichever comes first. Because that continuing check is assigned to the driver, the driver is the choice that fits. The passages do not say the loader or company supervisor carries this duty.
