43 . The air entering air storage tanks may contain:
Antifreeze.
The air that enters air storage tanks in an air brake system usually contains a certain amount of water and compressor oil. Because accumulations of these materials can damage the braking system, tanks are equipped with drains to allow their removal.
44 . In a newer vehicle, you apply the parking brake:
By using a black round knob.
In a newer vehicle with air brakes, the parking brake is controlled by a diamond-shaped yellow knob. The knob is pulled out to apply the parking brakes and pushed in to release them.
45 . The two indicators that determine when you should upshift are:
Oil pressure and air brake pressure.
There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.
46 . If the low pressure warning light comes on while you are driving:
You should continue driving, but turn the emergency flashers on to warn other motorists.
If the low air pressure warning light turns on, you should stop and safely park your vehicle as soon as possible. Controlled braking will be possible only as long as enough air remains in the tanks.
47 . When asked to make a lane change during the skills test, you should:
Not make the lane change if you don’t want to.
You will be asked to make multiple lane changes during the driving skills test. Before changing lanes, you should make the necessary traffic checks and use proper signals. Change lanes smoothly when you can do so safely.
48 . When using the controlled braking method in an emergency situation, you should:
Apply the brakes with minimal pressure.
The controlled braking method for emergency stops involves applying the brakes as hard as you can without locking the wheels. Keep steering wheel movements small when braking in this way.
49 . When driving down a steep grade:
The truck should be put in neutral as a way to slow down your vehicle.
When driving down a steep grade, you should rely primarily on the braking effect of the engine to slow down. To prevent overheating, use your brakes only as a supplement to this slowing technique.
50 . When approaching your vehicle, you should ensure that:
The vehicle is parked properly.
When approaching your vehicle before an inspection, make note of its general condition and ensure that it is not damaged or leaning. Look under the vehicle for fresh leaks. Check around the vehicle for hazards to movement, such as people, other vehicles, or low-hanging wires or tree limbs.
