Questions (172)
1. When a combination vehicle goes around a corner:
- The vehicle must use at least two lanes.
- The front and rear wheels will move in different paths. ✓
- It is best to allow the rear wheels to drive over the curb.
Answer: B. The front and rear wheels will move in different paths.
When a combination vehicle goes around a corner, the front and rear wheels will move in different paths. The handbook calls this off-tracking. As the vehicle turns, the rear wheels do not follow the same line as the front wheels. Longer vehicles off-track more, and a trailer's rear wheels off-track even more than the powered unit's rear wheels. That is why you steer the front end wide enough around the corner so the rear end does not run over the curb or pedestrians, while still keeping the rear close to the curb.
2. A placard indicating hazardous materials is shaped like a:
- Diamond. ✓
- Triangle.
- Circle.
Answer: A. Diamond.
A placard indicating hazardous materials is shaped like a diamond. The handbook says vehicles carrying certain hazardous materials must display warning signs called placards, and it describes those placards as diamond-shaped, square on point. The package-label passage also says hazard warning labels are diamond-shaped, so the diamond shape is the one tied to hazardous material warnings. That supports choosing diamond for the placard shape.
3. Gasoline:
- Can be brought onto a bus.
- May never brought onto a bus. ✓
- Can be stored in the passenger compartment of a bus during long trips.
- Should be stored in glass containers.
Answer: B. May never brought onto a bus.
4. If turning to avoid a hazard:
- You should brake hard.
- You should not brake as it could cause the wheels to lock. ✓
- You should turn the wheel very sharply.
- You should hold down the brakes until you are past the hazard.
Answer: B. You should not brake as it could cause the wheels to lock.
When you turn to avoid a hazard, you should not brake, because braking while turning can lock your wheels. The handbook's quick-turn guidance says plainly: do not apply the brake while you are turning. It explains that wheels lock very easily during a turn, and if they lock you can skid out of control. The ABS section makes the same point from the other direction — locked steering wheels mean you lose steering control, while ABS lets you steer around an obstacle. So the safe habit is to keep your foot off the brake through the turn and hold the wheel tightly instead.
5. If cargo containing hazardous materials is leaking, the driver should:
- Drive to find a phone to alert emergency personnel
- Drive to a designated hazardous materials clean up facility
- Park the vehicle and contact emergency personnel ✓
- Continue driving to the destination
Answer: C. Park the vehicle and contact emergency personnel
Park the vehicle and contact emergency personnel. The handbook says a leaking hazardous materials load should not be moved farther than safety requires. If you can get off the roadway safely, do that, but do not keep driving just to look for a phone or truck stop, because that leaves a trail of contamination. Your job is to warn people and give emergency responders the danger information and shipping papers. That points to stopping in a safe place and contacting emergency personnel instead of traveling with the leak.
6. Shippers must label hazardous materials. If an item is smaller than its label, how should the item be labeled?
- The item may be tied together with other hazardous materials and labeled with a sheet of paper on the outside of the bundle.
- The label may be attached to a tag that is securely attached to the package. ✓
- The item may be marked with a large orange dot.
- The item may be placed in a box displaying a warning label.
Answer: B. The label may be attached to a tag that is securely attached to the package.
7. Tar in road pavement often rises to the surface of the road in very hot weather. Spots where the tar bleeds:
- Are very slippery. ✓
- Offer the same amount of traction as the rest of the roadway.
- Offer more traction than the rest of the roadway.
- Will stop a vehicle.
Answer: A. Are very slippery.
Spots where tar bleeds are very slippery. The handbook explains that in very hot weather tar can come up through the pavement. It then states plainly that the spots where tar bleeds onto the surface are very slippery. Slippery means the tires have less grip there than on normal pavement, so the bleeding-tar answer matches the handbook. The other choices claim equal or greater traction, or stopping power, which the text does not support.
8. Containers of nitric acid should be:
- Stacked no more than two containers high. ✓
- Stacked to the ceiling.
- Loaded on top of other products.
- Loaded in the cabin.
Answer: A. Stacked no more than two containers high.
9. Keeping cargo centered on a rig can:
- Help you drive faster.
- Prevent a rollover. ✓
- Make turns more dangerous.
Answer: B. Prevent a rollover.
Keeping cargo centered on a rig helps prevent a rollover. The handbook's rollover-risk section says a load that sits off to one side can make a trailer lean, and that lean makes a rollover more likely. It lists keeping the cargo centered and spread out as one of the things that helps prevent rollover, along with keeping the load close to the ground and driving slowly around turns. So centering the load is a stability measure, not a speed measure.
10. ____ is responsible for properly labeling hazardous materials.
- The shipper ✓
- The loader
- The driver
Answer: A. The shipper
The shipper is responsible for properly labeling hazardous materials. The handbook lists packaging, marking, and labeling as shipper duties, along with preparing shipping papers and supplying placards. It also says shippers print required markings and labels and certify that the package was prepared according to the rules. The driver's job is to make sure the shipper identified, marked, and labeled the materials properly and to refuse improper shipments, not to do the labeling.
