15 . A low air pressure warning signal should activate:
When tank pressure falls below 5 psi.
In an air brake system, a low air pressure warning signal must come on if air pressure in the tanks falls below 55 psi. This warning signal may come in the form of a light, a buzzer, or a wig wag.
16 . When making a trip at night, you should do all of the following, except:
Do a complete vehicle inspection before driving.
To help ensure that you can see properly at night, do not wear sunglasses. If you wear corrective eyeglasses, make sure they are clean and unscratched. Get adequate sleep before your trip to help you avoid becoming fatigued. As always, do a complete inspection of your vehicle, paying particular attention to lights and reflectors.
17 . A driver can maintain alertness by:
Having another person ride with them.
To maintain alertness while driving, strategies include wearing sunglasses to reduce eye strain; maintaining a cool temperature inside the cab; avoiding heavy foods; and traveling with someone else who can share the responsibilities of driving.
18 . A cardboard box on the roadway:
Should be avoided by driving off the roadway.
Any foreign object on the road is potentially dangerous. For example, something seemingly harmless, such as a cardboard box or paper sack, could contain a hard or heavy object that could do serious damage to a vehicle.
19 . In a combination rig, it is best to make:
Slow, planned stops.
When driving a combination vehicle, it is important to brake well in advance and look far ahead of your vehicle to avoid the need for sudden stops. Making habits of these actions will help you prevent your trailer from jackknifing.
20 . A stopped bus:
Is a concern, whether passengers are visible or not.
Always drive cautiously around a stopped bus. Passengers may cross in front of or behind it, and the bus may prevent them from seeing your vehicle.
