Questions (146)
1. Class 1, Class 2.1, and Class 3 materials should not be placed in a trailer with:
- A heater. ✓
- An air conditioner.
- Other items.
Answer: A. A heater.
Class 1, Class 2.1, and Class 3 materials should not be placed in a trailer that has a heater. The handbook sets out a block of special Cargo Heater Rules and lists Class 2.1 flammable gas and Class 3 flammable liquids among the materials those rules cover. Elsewhere it says the rules usually forbid cargo heaters and warn against loading such products into a cargo space with a heater unless you have read all the related rules. For Class 1 explosives it adds a step-by-step precaution: shut the engine off, then disable the cargo heaters, disconnect their power sources, and drain their fuel tanks. The equipment those rules single out is the heater.
2. A Class 7 hazardous material is:
- Explosive.
- Flammable.
- Radioactive. ✓
- Corrosive.
Answer: C. Radioactive.
A Class 7 hazardous material is radioactive. The handbook passage on mixed loads labels Class 7 materials as radioactive, and it discusses packages bearing a transport index and Radioactive II or Radioactive III labels. That direct label ties the class number to the correct choice. The same section also mentions radioactive materials in other loading rules, such as keeping Yellow III packages in a closed cargo space. Since the source states Class 7 is radioactive, the answer follows directly from the handbook rather than from a guess about what the class number might mean.
3. Fuel records supporting IFTA quarterly fuel use tax returns must be kept by carriers for:
- One year.
- Two years.
- Three years.
- Four years. ✓
Answer: D. Four years.
Fuel records that support IFTA quarterly fuel use tax returns must be kept for four years. The handbook explains that the Individual Vehicle Distance Record is the source document used to calculate the fees and taxes owed to the jurisdictions where the vehicle runs. Because those original records can be audited by the taxing jurisdictions, the handbook says they must be kept for at least four years. That minimum is what makes four years the right retention period for the fuel and distance records behind an IFTA quarterly return.
4. If a driver cannot account for a student after the student has exited the bus, the driver should:
- Secure and leave the bus to look for the student. ✓
- Assume the student has safely exited the bus.
- Walk to the back of the bus to see if the student got back on.
- Ask another student if they've seen the student.
Answer: A. Secure and leave the bus to look for the student.
Secure the bus, then get out and check around and underneath the bus for the missing student. The handbook covers this exact situation: if you cannot account for a student outside the bus, secure the bus, take the key, and check around and underneath the bus. The student has already left the bus, so the search happens outside it. The passages also say to check all mirrors and make certain no students are returning to the bus before you prepare to leave. Leaving the bus to look for the student is the only choice that matches that instruction.
5. An underloaded front axle:
- Is important for smooth steering.
- Is encouraged as front axles are usually less strong than other axles.
- Is discouraged as it can cause steering problems. ✓
- Is discouraged as it can improve fuel efficiency.
Answer: C. Is discouraged as it can cause steering problems.
An underloaded front axle is discouraged because it can cause steering problems. The handbook explains that poor weight balance can make handling unsafe. When weight is shifted too far to the rear, the front axle can be under-loaded. That leaves too little weight on the steering axle to steer safely. So the problem is not just comfort or smoothness; the front axle needs enough weight for control. The bank answer matches this passage because it treats an underloaded front axle as something to avoid due to steering trouble.
6. In the event of a bus evacuation, students should be led at least ____ away from the road.
- 10 feet
- 20 feet
- 50 feet
- 100 feet ✓
Answer: D. 100 feet
Students should be led at least 100 feet away from the road during a bus evacuation. The handbook describes a safe evacuation place as being no less than 100 feet from the road, placed toward oncoming traffic. It gives the reason as keeping students clear of debris if another vehicle strikes the bus. The other listed distances do not match this evacuation rule; the 10-foot figure in the loading section is about having students stand where the driver can see them after leaving the bus at a stop.
7. To know which placards to use, you need to know:
- The hazard classes of the materials. ✓
- The types of containers holding the materials.
- The destination.
- The shipper.
Answer: A. The hazard classes of the materials.
You need to know the hazard classes of the materials. The handbook's placarding section lists the hazard class of the materials as one of the facts that decides placarding, and the placard tables are organized around hazard classes. It also links placard requirements to the amount shipped and total weight, but the class tells you which table and which placard applies. So to choose the right placard, start with the material's hazard class.
8. A driver needs a CDL with a hazardous materials endorsement to transport hazardous materials in:
- A vehicle requiring a Class A license.
- A vehicle requiring a Class B license.
- A vehicle requiring a Class C license.
- Any sized vehicle. ✓
Answer: D. Any sized vehicle.
A hazardous materials endorsement is required for any sized vehicle, including vehicles in Class A, B, or C. The handbook says the H endorsement applies to any driver, no matter whether the vehicle is Class A, B, or C, when the load is hazardous material that must be placarded or is a select agent or toxin in any quantity. It also says drivers of placarded vehicles must have a CDL with the hazardous materials endorsement. Because the rule is tied to the cargo and placarding, not to one license class, the requirement covers vehicles of any size.
9. During a basic vehicle control skills test, a look is when:
- A driver checks the gauges on their instrument panel.
- A driver checks their blind spots.
- A driver walks to the back of their vehicle to check its position. ✓
Answer: C. A driver walks to the back of their vehicle to check its position.
A look is when the driver walks to the back of the vehicle to check its position. The handbook says you are scored for a look when you open the door, leave the seated position while in control, or, on a bus, walk to the back for a better view. It also allows limited free looks during backing exercises to check the vehicle's position. So a look is tied to getting out of the driving position to inspect position, not to a quick glance at the dashboard or mirrors. That is why walking to the back of the vehicle to check its position fits the definition.
10. The drive shaft should:
- Be bent toward the passenger side.
- Be bent toward the driver’s side.
- Be bent to one side or the other.
- Not be bent. ✓
Answer: D. Not be bent.
