8 . Looking far ahead of your vehicle while driving is:
Good drivers look down the road at least 12 to 15 seconds ahead of their vehicles. This makes it possible to identify hazards early, when drivers are more likely to have time to respond appropriately.
9 . What can change the height of a vehicle?
Number of windows
The added weight of a heavy load will make a vehicle sit lower than usual. A vehicle will often be taller when carrying a light load than when carrying a heavy load. If your vehicle fits under an overpass while carrying a full load, it is not guaranteed that it will fit under the same overpass if it is empty.
10 . When should you slow for a curve?
You should always slow to a safe speed before entering a curve. Slowing while within the curve could cause a skid.
11 . Air tank drains:
Must remain open while driving.
In an air brake system, the air storage tanks are equipped with drains to allow water and compressor oil to be removed. The water and oil can damage the brakes if left to accumulate in the system.
12 . Broken suspension parts:
Are extremely dangerous.
The suspension system is responsible for supporting a vehicle, supporting its load, and keeping its axles in place. When inspecting your vehicle, check for damaged or missing spring hangers, spring leaves, shock absorbers, u-bolts, and frame members. Broken parts in the suspension system are extremely dangerous.
13 . Talking on a hands-free phone while driving:
While speaking on a hands-free phone while driving is less dangerous than speaking on a hand-held phone, it is just as likely to mentally distract a driver. Simply engaging in conversation takes their mental focus away from the task of driving.
14 . If you plan to slow down, you can warn drivers behind you by:
Putting your hand out the driver's side window and waving.
Before slowing down, it is a good idea to flash your brake lights by lightly tapping your brake pedal a few times. This will warn drivers behind you of your plans to slow down.
