Questions (123)
1. Outage:
Should not be considered when loading liquid cargo.
Is the same for each liquid.
Should be considered when determining how much liquid to load into a tank. ✓
Is only a concern in warm weather.
Answer: C. Should be considered when determining how much liquid to load into a tank.
Outage should be considered when determining how much liquid to load into a tank. The handbook says never fill a cargo tank completely. Liquids expand as they warm, so you must leave room for that expansion, and that space is called outage. Because different liquids expand by different amounts, they need different amounts of outage. That is why outage has to be taken into account when you decide how much liquid to put into a tank.
3. If you are transporting Class 3 flammable liquids and your cargo needs to be moved into another tank, the flammable liquids:
May be transferred on the roadway as long as no other people are nearby.
Should not be transferred on a public road, unless under emergency circumstances. ✓
Should be kept secret when they are being moved to another tank.
Should be transferred at night.
Answer: B. Should not be transferred on a public road, unless under emergency circumstances.
Flammable liquids should not be moved from one tank to another on a public road unless there is an emergency. The hazardous materials section says you should not move a flammable liquid between vehicles on a public road unless an emergency exists. That directly supports avoiding this transfer on a public road in normal situations. The same section also tells you to warn people of the danger and keep them away, which fits treating a transfer as something to avoid on a roadway rather than a routine task. It does not describe a general allowance for doing the transfer when the area happens to be clear.
The amount of packaging required to make the shipment.
The location on the trailer where items may be placed.
How the material should be loaded and unloaded.
Answer: A. The risks associated with the material.
A material's hazard class reflects the risks associated with that material. The handbook says plainly that a material's hazard class reflects the risks associated with it, and that there are nine different hazard classes, with the materials in each class listed in a table. So the class is a summary of the danger the material presents, not a statement about packaging or handling. The manual treats packaging and loading instructions as separate containment rules that tell shippers how to package safely and drivers how to load, transport, and unload, which is a different subject from the class itself.
6. Hazardous materials should be loaded and unloaded:
Away from heat sources. ✓
Near heat, if possible.
With sharp objects.
By being rolled.
Answer: A. Away from heat sources.
Hazardous materials should be loaded and unloaded away from heat sources. The handbook's loading section says many hazardous products become more dangerous when exposed to heat, and it tells you to load hazardous materials away from heat sources. It also says to protect containers during loading, which fits with keeping them out of situations that could damage them. That direct instruction makes keeping hazmat away from heat the correct choice.
7. When preparing to enter traffic, you should do all of the following, except:
Wait for a large gap between vehicles.
Be prepared for your vehicle to accelerate slowly, especially if it is loaded.
Make sure you can completely cross traffic, if necessary, without interfering with traffic.
Assume other drivers will make room for your much larger vehicle. ✓
Answer: D. Assume other drivers will make room for your much larger vehicle.
When preparing to enter traffic, you should not assume other drivers will make room for your much larger vehicle. The handbook's section on space needed to cross or enter traffic says you must judge the gap using your vehicle's size and weight. Slow acceleration and the room a large vehicle takes mean you may need a much larger gap than a car, and you should allow more room when heavily loaded. Before starting across, you must be sure you can get all the way across before traffic reaches you. Nothing in the handbook says other drivers will open a space for you, so that assumption is the exception.
8. Who is responsible for installing placards on a vehicle?
The shipper
The carrier
The driver ✓
The mechanic
Answer: C. The driver
The driver is the one responsible for putting placards on the vehicle. The handbook tells drivers of placarded vehicles that they must learn the placard rules, and it puts the duty on you behind the wheel: never drive a vehicle that needs placards unless you hold the hazardous materials endorsement. It also warns that failing to placard when it is needed risks lives because emergency responders will not know what hazardous cargo is on board. Placing that responsibility on the driver is consistent with the manual's approach, which treats placarding as part of your job as the hazmat driver rather than someone else's.
9. What should a carrier do if hazardous materials are not properly prepared?
Accept the shipment
Accept the shipment under protest
Accept the shipment, but make a notation on the paperwork
Refuse the shipment ✓
Answer: D. Refuse the shipment
The carrier should refuse the shipment when hazardous materials are not properly prepared. The handbook describes the carrier's job as checking, before transport, that the shipper correctly described, marked, labeled, and otherwise prepared the shipment — and it says plainly that the carrier refuses improper shipments. Since improperly prepared hazardous materials are exactly that, the carrier's role is to turn them down rather than move them. The driver's duties point the same way: the driver refuses leaking packages and shipments. So the correct action here is to refuse the shipment.
Are usually shorter than single commercial vehicles.
Are usually lighter than single commercial vehicles.
Require more skill to drive than single commercial vehicles. ✓
Are easier to drive than single commercial vehicles.
Answer: C. Require more skill to drive than single commercial vehicles.
Combination vehicles require more skill to drive than single commercial vehicles. The handbook describes combination vehicles as typically heavier and longer than single commercial vehicles, and it says directly that they need more driving skill. It adds that drivers of combination vehicles need more knowledge and skill than drivers of single vehicles. The answer choice matches that comparison exactly. The other choices describe shorter, lighter, or easier vehicles, which the same passage contradicts.
