36 . What must be on an air tank in an air-braked vehicle?
An oxidizer
All air tanks on air-braked vehicles must have one-way check valves located between the air compressor and the first reservoir. This prevents air from flowing out in the event of a leak.
37 . Which of the following is not an example of a driving hazard?
An ice cream truck
Passing an accident scene can be hazardous because the people involved in the accident may not be watching traffic, and the scene itself may distract other passing drivers. Ice cream trucks can create hazardous conditions because they attract children who may not pay attention to nearby vehicles. Shoppers near the roadway are often paying attention to stores, not passing traffic.
38 . When switching gears, what happens if you remain in neutral for too long?
The vehicle will be difficult to stop.
Remaining in neutral for too long when shifting gears may make it difficult to put the vehicle into the next gear.
39 . Dry bulk tanks:
Cannot be driven on interstates.
Dry bulk tanks require special care when being driven because they have high centers of gravity. Drivers should also be careful because the materials being carried can easily shift in transit, causing a change in the vehicle's handling.
40 . When entering fog, you should:
Slow down.
If at all possible, it is best to avoid driving in fog. However, if you must drive through fog, slow down before reaching it.
41 . When passing another vehicle, you should:
Wave to other drivers.
It is always safest to assume that other drivers, bicyclists, and pedestrians don't see you. Be prepared for the possibility that they may suddenly move into your path. It may be safe to lightly tap your horn or flash your lights as you pass.
42 . Laws about securing loads and regulating CMV weights may vary from state to state. During interstate travel:
The driver can choose which state’s laws to follow.
Commercial vehicle weight, securement of cargo, covering of loads, and where large vehicles can be driven are all regulated by federal, state, and local laws. These vary from place to place, so you must be aware of the rules that apply where you will be driving. State laws in the state in which you are driving take precedence.
